Clarke is part of the original 100 and was sent to juvenile lockup for treason. On The Ark, prior to being locked up, Clarke was a medical apprentice working under Abby. Once on Earth, she used these skills to serve as the primary medic for the Delinquents, saving both Jasper Jordan and Finn Collins from life-threatening injuries and helping the Delinquents when The Camp was infected with hemorrhagic fever.
After the deaths of Wells Jaha and Charlotte, Clarke becomes a co-leader of the Delinquents alongside Bellamy Blake. While in charge, Clarke is forced to make life-and-death decisions to help protect the Delinquents from both internal and external threats. After they are captured by Mount Weather, Clarke works hard to form alliances with the Grounders as she tries to free her people, even taking on a leadership role in Camp Jaha despite her mom being the Chancellor. After making the difficult choice with Bellamy to irradiate Mount Weather in order to save their people, Clarke sets off on her own in the second season finale.
In a video from Clarke's childhood, Clarke and her best friend, Wells Jaha, practice for the Unity Day Celebration. As Thelonious Jaha records their practice, Wells asks his father how the Ark stays in space. Clarke mentions that her dad told her it is the thrusters. Thelonious tells her that her father is correct.
A year before the Delinquents are sent to earth, Clarke overhears a conversation between her parents, Abigail Griffin and Jake Griffin, discussing a flaw in the Ark's life-support system and that it is failing. Later that day, Clarke plays chess with her best friend Wells Jaha. Clarke, distracted by the news, starts losing the game. Wells notices something is wrong with Clarke and questions her. Clarke swears him to secrecy and tells him about the flaw as well as her father’s plan to go public.
After coming home, Clarke overhears her father making a video to reveal the truth. She confronts him about the truth and yells at her father, calling him suicidal or dumb because he plans to break into the communications mainframe. Clarke insists on helping him but her father tells her no. Moments later, the door to their home opens and the Ark Guard arrest Jake for treason. Clarke hugs him and promises to warn the people. She struggles with the guards who hold her back as her father is taken away.
Clarke finds her father before his execution and is able to say one final goodbye before Jake is floated for his crime. Clarke watches as her father is sucked out of the airlock and cries in her mother’s arms. Clarke repeatedly apologizes, thinking her father’s death was her fault. Her mother insists it was not her fault. After her father is floated, Clarke is immediately arrested for treason and sent to solitary confinement in juvenile lockup.
Throughout the Series
In the Pilot, in 2149 CE, Clarke Griffin draws a picture on the floor of her room on the Ark. Two Ark Guards enter her room, one of whom orders Prisoner 319 to face the wall. One of the guards opens up a metal box containing wristbands. When Clarke sees the wristbands, she states that she does not turn 18 for another month. When the guard orders Clarke to remove her watch, she protests stating it was her father's. The guard grabs for her wrist and Clarke fights back. Overcoming both guards, Clarke escapes her cell. Outside of her cell Clarke sees guards escorting other juvenile Delinquents out of their cells. Clarke’s mother, Abigail Griffin, appears and hugs her daughter. Clarke believes The Council is reducing population to buy more time for the rest of the citizens. Abigail reassures Clarke that they are not being executed. Instead they are being sent to the ground, all 100 of them. A guardsman shoots Clarke with a tranquilizer.
When Clarke awakens, she finds herself on a drop ship headed for Earth. Clarke discovers that Wells Jaha is also on the drop ship and demands to know why. He reveals he got himself arrested. When they hit Earth’s atmosphere a message from Chancellor Jaha appears and explains to them that they were sent down to Earth because they are expendable. He also mentions that if they cooperate their crimes will be forgiven and their drop site is a military base called Mount Weather. While watching the video, Finn Collins gets out of his seat and performs aerial stunts near Clarke and Wells. Glen Dickson and another Delinquent follow Finn's lead and try to get out of their seats. Clarke yells for them to stay in their seats but they all ignore her. Finn realizes Clarke is the one who has been in solitary for over a year and she recognizes him as the idiot who wasted a month of oxygen on an illegal spacewalk. He defends himself by insisting it was fun. The two Delinquents break free from their seats and Clarke again urges them to sit down. Moments later the parachutes deploy sending the two Delinquents and Finn flying. They realize the drop ship is coming in too fast. Wells worries because the retrorockets should have fired but have not. Clarke reassures that they will. Wells admits that he has something he wants to say to Clarke. Wells apologizes for getting her father arrested. Clarke tells him not to talk about her father. Wells persists stating he does not want to die with Clarke hating him. Clarke declares her father was executed so she does hate him. The retrorockets fire and the drop ship lands on Earth. The Delinquents begin to recover from their landing and unstrap themselves. Clarke gets out of her seat and checks on one of the two Delinquents who followed Finn out of their seats. Clarke asks if the other is breathing. Finn exchanges a look with Clarke, indicating that both Delinquents are dead.
Clarke descends from the ladder to the ground level of the drop ship and stops Bellamy Blake from opening up the drop ship door, explaining the air could be toxic. Bellamy tells her that if the air is toxic they are all dead anyway. Bellamy goes to open the door when a young woman hesitantly calls out his name. A Delinquent shouts out the young woman is Octavia Blake, Bellamy’s sister and the girl they found hidden in the floor. This angers Octavia, causing her to try attacking the Delinquent who made the comment, however, Bellamy stops her. Bellamy offers Octavia something else for people to remember her by: the chance to be the first human on the ground in over 100 years. This excites Octavia. Bellamy opens up the drop ship door and Delinquents experience their first breath of fresh air. Octavia steps out of the drop ship and savors the feeling of being on Earth. Bellamy blocks the others from leaving the drop ship as Octavia jumps onto the ground and smiles. Behind her, the Delinquents and Clarke take in the sights of Earth. Octavia throws her fists into the air and shouts in excitement.
The rest of the Delinquents smile, shout, and cheer as they race out of the drop ship to explore their new world. Clarke jumps onto the ground and her face lights up in excitement. Clarke’s excitement is short lived when she realizes they are not on Mount Weather and that a radiation-soaked forest sits between them and their next meal. Clarke is plotting a route to Mount Weather when Wells informs Clarke that the communications are down. Clarke decides they need to worry about getting to Mount Weather and shows him the path they need to take. Wells asks her where she learned to do that. When Clarke does not answer, Wells realizes her father taught her. Jasper Jordan approaches and playfully flirts with Clarke. Wells roughly grabs his arm and pushes him away. John Murphy sees this and confronts Wells, stating Jasper is one of them. Wells tries to talk Murphy down but is interrupted by Bellamy. Wells explains that they need to find Mount Weather. Octavia mocks Wells and Clarke because they are considered privileged. Clarke informs the Delinquents that she doesn't care who is in charge. She warns them they need to go because the longer they wait the hungrier they will get. Bellamy proclaims Clarke and Wells should go, while the rest wait for them to return with food and supplies. Wells tries to make Bellamy understand that they all need to go. John Murphy shoves Wells trying to start a fight while John Mbege holds Clarke back. Before the two can fight, however, Finn intervenes and tells John Murphy to wait until it is a fair fight. Octavia approaches and suggestively hints for Finn to save her next. He flashes Octavia a smile before walking away.
Clarke goes to check on Wells' injured leg and Finn approaches them and asks when they leave. Clarke tells him "now" before turning to Wells and stating that they will be back tomorrow with food and supplies. Wells questions how two people are going to carry enough food for 100 people. Finn turns, pulling Jasper and Monty Green into the group and mentions there are four now. Octavia invites herself along for the journey even as Bellamy tries to stop her. When Clarke spots a scuff mark on the side of Finn's wristband she scolds him and tells him that the wristbands transmit vital signs to the Ark. If they take them off the Ark will think they are dead, unknowingly giving Bellamy an idea. Clarke sets out for Mount Weather with Finn, Jasper, Monty, and Octavia.
Walking through a lush forest, the group takes their time admiring Earth. Clarke asks them to hurry up and Finn asks how she can block it all out. Clarke wonders why they have not seen any animals and that maybe there are none because they might have been exposed to enough radiation to kill them. They continue walking and Finn asks Monty and Jasper how they got busted. They tell him they were arrested for stealing from the Ark's garden and forgetting to replace what they took. Jasper asks Octavia what she was arrested for. She replies for being born and rushes off to join Clarke, who motions for everyone to join her. In front of them is a deer grazing in the field. Finn snaps a twig and the deer turns to them, shocking the group with its two heads.
As they continue on their journey to Mount Weather, Finn asks why all of a sudden they were sent down to earth after 97 years. Clarke tells them it is because the Ark is dying and only has three to four months of life support left and that is the reason she was locked up in solitary and her father was floated for it. Monty asks if they are going to kill more people and Octavia says they should all float after what they did to her. Octavia then takes off to the edge of a stream and strips off her pants as everyone ogles her. Clarke asks Octavia what she is doing just before Octavia leaps into the water below. Monty reminds Octavia they don't know how to swim and Octavia laughingly stands up, showing them it is shallow water. Clarke is confused because a river is not supposed to be right there but they all start taking off their clothes to join Octavia. Jasper spots something in the water and shouts at Octavia to get out of the water. Octavia is suddenly pulled under by a river snake. She comes up a bit farther downriver, screaming. Clarke, Monty, and Finn toss a boulder into the water to distract the river monster but Octavia is left in too deep water and is unable to swim to shore. Jasper jumps in and grabs her just as the creature comes back and he is able to pull Octavia to shore in time.
Clarke awakens while it is still dark out. Jasper, Monty, and Octavia are asleep behind her as she sits up and witnesses the trees and plant life aglow with bioluminescence. Finn approaches her with a leaf filled with water for her to drink from. He then shows her some tracks in the dirt and says he thinks there might be monkeys. The next morning, down by the river, Finn is holding onto a vine, about ready to swing across the river to the other side. Jasper tells him to let go at the apogee. As Finn is about to take off, Jasper asks if he can go first so he can impress Octavia. Finn agrees and Jasper goes soaring across the river, letting go as he screams, "Apogee!" and lands safely on the other side. They all begin cheering and Clarke is up next. Jasper picks up a sign reading, "Mount Weather," and holds it above his head, telling them they had reached Mount Weather. He is suddenly knocked off his feet and propelled back, pinned against a tree with a giant spear protruding from his chest. Clarke, Finn, Monty, and Octavia all duck down in fear as they realize they are not alone.
In Earth Skills, Clarke, Finn, Octavia, and Monty flee through the woods after witnessing Jasper getting speared by the Grounders. Monty trips and falls and they see a misshapen human skull on the ground. They hear Jasper screaming and race back to the river bed to find Jasper gone. When they return to The Camp, Wells and Murphy are in the middle of a fight. Wells holds a knife against Murphy's throat when Clarke arrives and stops the fight. Bellamy rushes over to Octavia when he sees she was injured and asks where the food is and what happened. They tell him about the Grounders and all the Delinquents gather around to listen as Clarke explains how the Grounders took Jasper. Clarke then sees Wells' wristband is missing and tells them they are idiots because life support on the Ark is failing and taking off their wristbands is killing everyone on the Ark as well as all the Delinquents because they need the people from the Ark to come down and help them. Bellamy then tells them that they do not need the people on the Ark because they are not criminals but fighters and survivors. Clarke tells Monty it is time to go after Jasper.
Later, Wells finds Clarke in the drop ship gathering supplies and wants to go with her to find Jasper. She tells him she does not want him around. Monty tells her that they also need him to search because no one else has volunteered. Clarke tells Monty he is not going either because he has to figure out how to communicate with the Ark. Finn arrives and she asks if he is ready. He tells her he is not going because the spear was thrown with "pinpoint accuracy." Clarke calls him a coward and leaves. Outside the drop ship, Clarke approaches Bellamy who is tending to Octavia's injury. Octavia tells Clarke she is coming but Clarke tells Octavia her leg will just slow them down. She wants Bellamy to join them because he has a gun. She tells him he will go because he wants the rest of the Delinquents to follow him and they will think he is scared if he does not go. Bellamy tells Murphy to come with him and orders Atom to watch Octavia. Wells warns Clarke about Bellamy and Murphy being dangerous criminals and Clarke tells him she is counting on it. Bellamy tells Murphy that he is getting Clarke's wristband so the people on the Ark won't come down if they think both Wells and Clarke are dead. Bellamy grabs Clarke's wrist and says she needs to take her wristband off. Clarke tells him the only way that is happening is if she is dead. Finn arrives just then and says they should split up to cover more ground and he walks off with Clarke.
As they walk, Finn asks Clarke why the Grounders did not attack Jasper until after they crossed the river. Clarke tells him the river is a boundary, meaning Mount Weather is off-limits. They discover a trickling waterfall spilling into a pond and Clarke is relieved they do not have to worry about fresh water. Finn pulls her into the water and they splash around for a moment and discuss her father before Clarke sees Jasper's blood on some rocks on the other side of the pond and tells Finn they need to get the others. Murphy asks if they are going in the right direction and Finn spots some more blood before they hear someone moaning in the distance. They head toward the sounds and they find Jasper strung up to a tree. Clarke hurries up to him but falls into a covered pit with Bellamy grabbing her arm just in time. He seems to contemplate letting her go for a brief moment before they all manage to pull Clarke up. Finn offers to climb up and cut Jasper down. Finn and Murphy are cutting Jasper down from the tree when they hear a low growling coming from a black jaguar. Clarke calls for Bellamy to use his gun but when Bellamy reaches for it, he finds Wells had stolen it. Wells uses the gun and fires multiple times at the jaguar, grazing it once. The jaguar pounces toward Bellamy and Wells fires the last bullet, killing the jaguar. Bellamy tells Wells that now Clarke sees him. Clarke, Finn, and Wells return to The Camp with Jasper while Bellamy and Murphy return with the dead jaguar for dinner.
Later, while Clarke is tending to Jasper in the drop ship, Finn presents her with a metal two-headed deer trinket. Clarke and Finn leave the drop ship and find the Delinquents are removing their wristbands for food. Finn walks up and grabs some jaguar meat with Murphy stopping him and asking if he plays by different rules. Finn tells him he thought there were no rules before walking off. Clarke also grabs some food and walks off. As they eat their dinner, in the trees up above the Delinquents, a Grounder watches The Camp silently.
In Earth Kills, in the drop ship, Clarke is checking Jasper's pulse after he was speared by Grounders. She tells Monty to keep an eye on Jasper while she goes to get him some water. Once outside the drop ship, she hears a 13-year-old-girl, Charlotte, crying out in her sleep and goes to wake her from her nightmares. Charlotte tells Clarke that she sees her floated parents in her dreams. Clarke tells her that her dad was floated, too and she asks Charlotte what got her locked up. Charlotte tells her that she assaulted an Ark Guard who took her parents' things to the redistribution center. Clarke points out a bright star in the night sky and tells Charlotte that the Ark up there is something they can move past and the ground is their second chance.
Later, in the drop ship, Clarke is inspecting Jasper's wound and realizes the Grounders saved his life by cauterizing the wound. She notices that the wound is infected and worries that he might be septic and tells Wells to hold Jasper down. Just then, Jasper's cries turn to screams as Clarke tries to cut away Jasper's infected flesh. Bellamy arrives and tells Clarke she cannot save Jasper's life and his screams are making people uncomfortable. Clarke tells Bellamy that this is not the Ark and down here every life matters. Bellamy calls Jasper a "lost cause" and tells Clarke if Jasper is not better by tomorrow, he will kill Jasper. Bellamy tells Octavia to leave with him but she refuses. Finn tells Clarke that Bellamy happens to be right. Clarke tells Finn that he and Bellamy are wrong and that Jasper is not a lost cause. She takes apart the poultice the Grounders had used on Jasper and Wells recognizes the red plant as seaweed. Clarke, Finn, and Wells then leave to go find the seaweed. On their hike, Wells tries to discuss their relationship but Clarke refuses. They stumble across an old vehicle buried in the dirt and Clarke tells them they can look at it later because Jasper can't wait.
Once Clarke, Wells, and Finn reach the riverbank, Wells points out the red seaweed floating in the water. Finn starts discussing a way to retrieve the seaweed while Clarke wades in and grabs it. A flock of birds suddenly swarms overhead as a foghorn is heard. They look up into the sky and see a massive, yellow storm cell bearing down on them. Clarke tells them to run. They flee the Acid Fog and take shelter in the abandoned vehicle. In the vehicle's glovebox, Finn finds some whiskey and he and Clarke begin drinking from it. Clarke gets tipsy from the whiskey and grumpily complains how she can be fun. Wells tells her she is fun and then tries to reminisce with her before Clarke interrupts him, saying, "remember that time you betrayed me and got my father executed?" She then goes on to ask him why and Wells admits he made a mistake. Clarke tells him she wants an explanation and Wells says he can't give her one beyond trusting his father. Wells grabs the whiskey from Finn and takes a swig.
Once the fog has cleared, they head back to the camp with Clarke walking ahead. Finn tells Wells that he knows Wells is covering something up. Finn later tells Clarke that Wells isn't giving her a straight answer about Clarke's dad and he wants to know how sure Clarke is that Wells is the one who told about Clarke's dad. Clarke eventually comes upon Bellamy. His is holding a knife, trying to work up the courage to mercy-kill Atom who had gotten trapped in the Acid Fog when he notices Clarke arrive. Clarke kneels on the other side of Atom and shakes her head at Bellamy that she will not be able to save him. She tells Atom she is going to help him and begins humming to him as she takes the knife from Bellamy's hand. She gently pushes the knife into Atom's carotid artery and continues to hum to him as he expires. Meanwhile, Charlotte observes, hidden from view.
Later that night, they return to camp with Atom's body. Bellamy orders them to get Clarke whatever she needs as Wells tells Bellamy he will go dig Atom's grave. Back in the drop ship, Clarke has made a tea from the seaweed and is forcing Jasper to drink it. She tells Octavia that she is sorry about Atom and Octavia says they will have to get used to people dying, but not Jasper. Clarke then finds Wells digging Atom's grave and asks him if it was her mother who told his dad about Jake's plan to go public with the life-support failure on the Ark. She did not want to believe her father's death was her mother's fault and this whole time Wells had let her believe it was him to protect her from that. Clarke asks if he can forgive her and he tells her it is already done and they hug.
In Murphy's Law, at The Camp, all is quiet as Clarke leaves flowers at Wells' grave. Finn approaches and tells her she should not be out all alone because that is how the Grounders got Wells. He then produces a colored pencil and tells her he got it at the Art Supply Store. Clarke begins to reminisce how Wells was always getting her drawing materials by trading in his own stuff on The Ark. She tells Finn how Wells let her hate him so she wouldn't hate her own mother for killing her father and decides to make her mother feel what she is feeling. She heads to the drop ship and has Monty remove her wristband so her mother will think she is dead. Monty tells Clarke that he did it and was able to keep Clarke's wristband fully operational. Now all he needs to do is patch it into the drop ship mainframe and they will be talking to the Ark by nightfall.
Later, Clarke and Bellamy are approached by Octavia and Jasper who bring them Wells' fingers and the murder weapon: a knife. Clarke realizes the knife belongs to a Delinquent and that the Grounders did not murder Wells; it was one of them. Bellamy tells Clarke she needs to keep this quiet because fear of the Grounders is building the wall that is keeping them safe. Clarke points out the knife belongs to John Murphy and the Delinquents have a right to know that he murdered Wells. Clarke storms out of the tent and confronts Murphy about the knife. She tells Murphy he is going to pay for it and Octavia pipes up that Murphy also tried to kill Jasper. Murphy says he does not have to answer to anyone when Bellamy steps in. Murphy tells Bellamy he did not do it. Clarke asks the crowd if they want a society with no rules. Connor shouts out that they should float Murphy and the crowd agrees. Connor says it is justice but Clarke calls it revenge. Connor then begins a chant to float Murphy and the crowd attacks Murphy and beats him as he is bound and gagged. They string up a noose and wrap it around his neck as Clarke begs them to stop. They pull Murphy up on the rope, hanging him from a branch and Connor gets the crowd to chant for Bellamy to kick the crate out from under Murphy. Clarke pleads with Bellamy, telling him she saw him with Atom and knows he is not a killer. Bellamy shoves her away and kicks the crate out from under Murphy, yelling at Clarke that it is her fault for letting everyone know that the Grounders did not kill Wells. As Murphy twists and wriggles at the end of the rope, Finn comes running up and tries to put a stop to it but Connor holds him off. Charlotte pushes forward and admits that she was the one who killed Wells. Clarke grabs the ax from Bellamy's waist and cuts the rope holding Murphy as Finn unties him.
Bellamy, Clarke, and Finn then take Charlotte inside a tent to protect her from the angry Delinquents. Charlotte tells them she was trying to slay her demons. Outside, Murphy is calling for Charlotte and to let him punish her like they wanted to punish Murphy. Bellamy tells Clarke and Finn to stay inside the tent with Charlotte while he goes outside to deal with Murphy. Clarke and Finn then escape with Charlotte. They are trekking through the woods when Charlotte reaches for Clarke's hand. Clarke jerks her hand away and calls Charlotte a killer and tells her she cannot just kill someone to make herself feel better. They hear Murphy and his followers calling out for Charlotte. Finn gestures to a hatch in the ground, revealing his Art Supply Store, or rather a pre-war bunker that the inhabitants never made it to. They tuck Charlotte into bed and Clarke tells Finn they should share all of the supplies with the group but he thinks they should keep it secret. Clarke thinks the original owners might have been better off dying before making it to the shelter. She tells Finn she doesn't know what to do about Charlotte and that it is all her fault as she should have listened to Bellamy about confronting Murphy. Charlotte listens to their conversation quietly from her bed.
Clarke awakens in the bunker to discover Charlotte missing and wakes Finn up. Meanwhile, Charlotte is running in the woods when Bellamy grabs her and tells her to keep quiet. Clarke and Finn hear Charlotte screaming for Murphy and think that Murphy might have her. Clarke arrives at the cliff-side where Murphy has Charlotte and Bellamy trapped. She tells Murphy it has gone too far. Murphy takes Clarke hostage and Charlotte begs him not to hurt Clarke. Murphy tells Charlotte if she comes with him he will let Clarke go. Bellamy stops Charlotte from going to Murphy and Charlotte says she can't let anyone get hurt any more because of her before she turns around and jumps off the cliff to Bellamy's and Clarke's screams of protest. Bellamy turns and tackles Murphy, punching him over and over in the face until Finn pulls Bellamy off Murphy. Bellamy tells Clarke that Murphy deserves to die. Clarke tells him they do not get to decide that and she was wrong before and they need rules. She tells him they will make the rules and they should banish Murphy. Bellamy picks Murphy up and holds him near the cliff's edge, telling him that if Murphy ever comes back to The Camp, Bellamy will kill him. He then tells Murphy's four followers that they can either go back to camp or they can go with Murphy and die. The four followers head back to camp with Bellamy and Clarke while Finn tosses Murphy a knife before leaving.
Back at The Camp, Clarke and Bellamy explain the new rules to the rest of the Delinquents. Later at the drop ship, Monty has the wristbands ready to hook up to the drop ship Jasper the honor of making the final connection. As Jasper makes the connection, it fries everyone's wristbands and Jackson in Earth Monitoring Station witnesses all of the remaining wristbands terminating at once. Finn takes off in frustration and Clarke follows after him. She catches up to Finn at the bunker where he is throwing things around in anger because he thinks everyone is now going to die on the Ark and they are now all alone on earth. Clarke tells him he is not alone and they have sex as Raven Reyes descends toward earth, her raven necklace from Finn floating weightless in the escape pod.
In Twilight's Last Gleaming, Clarke and Finn are still in the bunker discussing the night before when they had sex and Clarke tells Finn she needed him and wanted it to be him. Finn jokes he just wanted to have his first earth sex and Clarke was around and "passably cute." They start kissing again. Later, Clarke and Finn sit outside the bunker and Clarke tells Finn they should share the supplies with the other Delinquents but Finn tells her they should keep it a secret so they have someplace to hide if they need to. They kiss again just as Clarke sees Raven'sdrop ship falling to earth. Finn tells her it is a shooting star and she should make a wish. As the drop ship continues to fall, Clarke realizes it is not a shooting star. Clarke and Finn get ready to leave the bunker to find out what might have been sent down from the Ark. Clarke is hopeful there is a radio.
Clarke and Finn arrive back at the camp and Fox approaches them, saying that Bellamy told everyone to wait until sunrise before looking for the drop ship. Clarke goes to look for Bellamy in his tent and finds Roma who tells her Bellamy already left a while ago. Clarke realizes Bellamy went after the radio in the drop ship and takes off after him with Finn following. Clarke blames herself for getting distracted by Finn.
Later, at the crash site, Raven awakens in the pod and removes her space helmet, discovering she has a head injury just as Clarke opens the pod door and sees Raven. Raven then steps onto the ground for the first time, twirling in amazement and asking if it is raining. Clarke nods with a smile on her face and welcomes Raven to earth. Finn arrives and calls out to her. Raven runs up to him and they reunite and kiss passionately, much to Clarke's surprise. Finn asks Raven how she got to earth and she tells him how she rebuilt the pod. Raven starts to feel light-headed and Clarke comes over to assist with her head injury. Finn introduces Clarke to Raven and Raven tells Clarke how it was all Abby's doing. She then tells them about the planned culling and how they need to alert the Ark that the Delinquents are alive. They discover the missing radio and Clarke tells Finn and Raven they need to find Bellamy.
Clarke catches up to Bellamy in the woods and orders him to tell her where the radio is. She tells him about the Culling and how they are getting ready to kill 300 people for oxygen. Finn and Raven arrive and Raven tells him that they have been looking everywhere on the Ark for him. Bellamy tells her to shut up as Clarke asks why. Raven tells them how Bellamy shot Jaha and Clarke realizes that is the reason why he took the wristbands. Raven demands to know where her radio is and Bellamy tells her he should have killed her when he had the chance. Raven challenges him to do it and he shoves her up against a tree as she pulls a knife on him and asks again where her radio is. Bellamy lets her go and tells them Jaha deserved to die. Raven tells Bellamy he was a lousy shot and that Jaha is not dead. Clarke tells Bellamy this means he is not a murderer; he was just protecting his sister. Now it is time to protect 300 people and give them back the radio. Bellamy tells her it is too late.
Bellamy then has several Delinquents searching for the missing radio in the river where he tossed it. Finn tells Clarke he should have told her about Raven. Clarke tells him she gets it: she was around and "passably cute." Just then, Jones finds the radio. Raven tells them it will take at least a half day to dry it out to see what is broken. Clarke yells at Bellamy for what he did and that 300 people will die because of him. Raven interrupts and tells them they don't actually have to talk to the Ark; they just have to let them know they are alive. Raven begins organizing the Delinquents on stripping her pod for spare parts to create rocket launchers. Clarke asks if they will be able to see the rockets from the Ark and Raven tells her that Abby will be watching for them. The Delinquents set up the launchers for the flares. They start lighting off the rockets and watch as they go soaring into the evening sky. Bellamy asks Clarke if she thinks the Ark will be able to see the rockets. She tells him she does not know and wonders if they can wish on the flares as a shooting star. Bellamy tells her he would not know what to wish for.
In His Sister's Keeper, Bellamy is wandering around The Camp, looking for Octavia because he can't find her. Clarke offers to help search. Bellamy gathers a search party of Delinquents to help look for Octavia and asks for Finn specifically because they need a tracker. Finn and Clarke talk as a meteor shower appears overhead. It is actually the bodies of the 320 Ark citizens who were culled being returned to earth. Raven tells Bellamy it's all his fault for taking the radio. Bellamy brushes her off, saying he needs to find his sister and the search party leaves. Clarke and Raven stay behind to go to the bunker to see if they can find a transmitter for the radio.
Clarke and Raven head to the bunker as they discuss their mothers. Raven tells her that it was because of Finn that she survived on the Ark. Once inside the bunker, Clarke and Raven start digging through the supplies and they find part of a remote control car that will work for their radio transmitter. Raven also finds the metal two-headed deer trinket that Finn had made for Clarke. Once back at the Camp, Raven confronts Clarke about the two-headed deer. Clarke tells Raven that she did not even know Raven existed. Raven asks Clarke if she loves Finn and Clarke replies that she hardly knows him. Later, as Bellamy carries an injured Finn back to camp and calls out for Clarke to save his life, Clarke tells Raven to fix the radio because she needs her mother's help to save Finn's life.
In Contents Under Pressure, The Camp is battening down the hatches in preparation for a hurricane while Raven tries to get through on the radio to The Ark and Clarke is tending to a severely injured Finn. Up on the Ark, Abigail Griffin is before the Council and is told that even though she had broken laws and should be floated, they need her medical expertise too badly so she's received a stay of execution. They suddenly hear Raven calling over the Ark-wide channel, asking for help from the ground. Sinclair boosts the signal and Abby is able to talk to Clarke for the first time. Clarke asks for help with Finn and tells Jaha that Wells didn't make it. Sinclair patches Clarke through to Medical so Abby and Jackson can help Clarke with Finn's stab wound. The storm, however, temporarily disrupts the communications.
Octavia returns to the drop ship with Monty's moonshine to help disinfect Finn's injury. Bellamy, Miller, and Drew return, carrying the unconscious Grounder who had saved Octavia's life and stabbed Finn into the drop ship. Bellamy tells them to tie him up on the third floor while they send the rest of the Delinquents to the second floor to give Clarke room to work on Finn. Abby gets back on the radio and Clarke describes Finn's injury to her. Abby guides Clarke through removing the blade from Finn's side. As Clarke is doing so, the storm gets worse and debris hits the drop ship, knocking everyone down, including Clarke and Finn. Luckily, the blade was removed without doing further damage. Clarke finishes stitching up Finn's wound and realizes he is feverish. Abby wants to talk with Clarke but Clarke leaves to the third level.
Bellamy asks how Finn is doing and shows Clarke the Grounder's journal where he has a drawing of the drop ship and tally marks counting the Delinquents. He tells her they are fighting a war just as Raven calls up to Clarke that Finn has started seizing so Clarke rushes back down to him. Clarke is able to stop Finn from seizing and quickly realizes that the blade Finn was stabbed with had been poisoned. She heads back up to the third floor with Octavia following her. Bellamy remembers the vials they had found in the Grounder's bag and brings them to her. They ask the Grounder to tell them which one has the antidote but he refuses to speak. Bellamy tells Clarke she does not have to be there while he tortures the Grounder to find the antidote but Clarke stays. Octavia begs Bellamy to stop, telling him the Grounder had saved their lives even though Finn was dying downstairs. Bellamy brutally tortures the Grounder, whipping him with a seat-belt, yet the Grounder still will not speak. Bellamy and Clarke escalate the torture of the Grounder with Bellamy putting a spike through his hand. Raven comes into the room after Finn almost dies again and begins to electrocute the Grounder, causing him to scream in agony. Octavia puts a stop to it by slicing herself with the knife that the Grounder used on Finn, saying that the Grounder wouldn't let her die. The Grounder finally helps Octavia find the correct antidote to save her (and Finn). Clarke goes downstairs and gives the antidote to Finn while she sends Raven out for water. Abby comes on the radio and Clarke tells her she knows about her mother's involvement in her father's death before turning off the radio and sobbing in sorrow.
Later, Clarke tries to clean the Grounder's wounds but he sees Octavia enter the room and refuses to let Clarke do so. Octavia walks over to help and he allows her to clean up his wounds. Clarke tells Octavia that they tortured him to save Finn. Octavia replies that Clarke didn't even save Finn; Octavia did. Clarke leaves to check on Finn again. When Finn wakes up, Clarke tells Finn that Raven needs him and calls Raven over to him. Clarke leaves the drop ship and sees the Delinquents cleaning up the camp after the storm. Bellamy approaches her, taking the spike that had been in the Grounder's hand and tells her, "who we are and who we need to be to survive are very different things," and that it is hard being in charge.
In Day Trip, Clarke uses the Camp's newly established video chat to attend a Council meeting. Chancellor Jaha wants to know more about the Grounder in hopes he can provide insight on how to survive the winter. Clarke deflects the question by saying they are doing everything they can to prepare for the winter and admits that they will freeze before they starve. Marcus Kane believes he can help prevent that and shows Clarke coordinates to an old Emergency Aid Depot that is not far from their landing site. Kane and Jaha explain that it should have supplies and that it can be used as a shelter for the Delinquents and the citizens of the Ark during the winter. Jaha then asks for a moment alone with Clarke before telling her everyone is proud of what the Delinquents have accomplished on Earth; especially Clarke’s mother, Abigail Griffin. Jaha tries to get Clarke to forgive her mother, however, Clarke does not believe she will ever forgive her mother or Jaha for betraying and killing her father. Clarke changes the subject to the kids who actually want to talk to their parents and leaves to find Dax.
Clarke then returns to the drop ship and calls out for Bellamy. Bellamy snaps at Clarke and tells her no, he still will not talk to Jaha. Clarke tells him about the Emergency Aid Depot and invites him along because she does not want to be around anyone she actually likes at the moment. Bellamy smiles at her honesty and agrees to go with her and Clarke leaves to check in on Finn who is still recovering from a stab wound. Raven is also there and things are awkward while Clarke cleans Finn's wound. She asks Raven to change his bandages in a few hours to make sure Finn stays in bed before she leaves with Bellamy. She notices Bellamy packing more rations than necessary for a day trip and comments, but he brushes her off by saying a lot can happen in a day.
As they are walking through the woods, Clarke mentions that the first drop ship will be coming down soon and that Bellamy cannot avoid Jaha forever. They reach the coordinates and see ruins amidst a swamp. Bellamy says there has to be a door and they split up but stay within shouting distance. Clarke soon shouts out that she found a door. As the two explore the depot they quickly realize that the place is ruined and disgusting. They realize that the Delinquents and Sky People will not be able to live down there. Bellamy finds a box of glow sticks and begins lighting them. Meanwhile, Clarke finds a box full of blankets. While Clarke is happy they found something Bellamy is not when he opens up a metal barrel only to find it full of grease. Angry, Bellamy kicks the barrel over. After the barrel topples over, Bellamy discovers a bunch of assault rifles and ammunition that were stored inside. Bellamy asks Clarke if she’s ready to be a badass and insists on teaching Clarke how to shoot as he eats the Jobi Nuts. When he fixes Clarke’s stance, Bellamy notices how close he is to her and gets flustered. Taking one of the rifles Bellamy decides to demonstrate instead. Bellamy pulls the trigger and the bullet is a dud. Bellamy tells Clarke to try hers. After she shoots for the first time, she is amazed by the feeling and questions if she should feel horrible for feeling that way. They then discuss the Delinquents and Bellamy tells Clarke to keep Miller close. Clarke realizes Bellamy is planning on running away and tries to convince Bellamy to stay, saying Octavia needs him. Bellamy tells her Octavia hates him and she’ll be fine. Flustered, Bellamy tells Clarke to keep shooting and leaves to go get some air.
Clarke tries to shoot her weapon again, only she starts hallucinating and envisions that she is back in her cell on the Ark along with her father, Jake Griffin. Clarke starts hugging her father but pulls away when she realizes her father is not real. Jake tries to get her to forgive her mother. Clarke breaks down over the growing pressure of everyone counting on her and over her torturing the Grounder. Clarke says her mother doesn't deserve her forgiveness and her father tells her that forgiveness is not about what people deserve. Clarke is still reluctant, and then the hallucination changes as Jake calls her a crazy bitch. Clarke is confused as Dax stands behind her, calling her a crazy bitch just before he hits her on the head with one of the rifles and knocks her out.
Dax then goes after Bellamy who is suffering from his own hallucinations. Dax shoots at Bellamy but the bullet jams so Dax ejects it onto the ground and aims again. Just before Dax can pull the trigger and kill Bellamy, Clarke appears pointing a rifle at him. Dax tells Clarke she should have stayed down in the depot; he tried not to kill her but Commander Shumway said no witnesses. Clarke is confused and Bellamy explains Shumway set it up and gave him the gun to shoot the Chancellor. Clarke tells Dax to put the rifle down. When Dax refuses, Clarke pulls the trigger but her bullet is a dud so she runs and hides behind a tree as Dax fires at her. Bellamy realizes Dax is going to kill Clarke and tackles him, sending both of them to the ground as the two get into a fist-fight with Dax gaining the upper hand. Clarke is unable to figure out how to unjam her gun so she charges at Dax. Dax, however, thrusts the end of his rifle into Clarke’s stomach, knocking her to the ground. Clarke’s distraction allows enough time for Bellamy to grab the forgotten bullet and lodge it into Dax’s neck. Dax dies quickly after.
Afterwards, Clarke tells Bellamy that he is okay to which Bellamy replies that he is not okay. Leaning up against a tree, Bellamy breaks down and says he is a monster. Clarke consoles him, telling him that she needs him, that they all need him, and that he is forgiven. He can’t run because he has to return with her face it. Bellamy asks if she means like how she faced her mom. Clarke admits that she does not want to talk to her mother or face any of it. All Clarke thinks about is trying to keep everyone alive but they do not have a choice. Bellamy still thinks Jaha will kill him when he lands on Earth. Clarke responds that they will figure something out. Bellamy asks her if they can do it another time. Clarke leans back on the tree and tells him whenever he is ready.
When Bellamy and Clarke arrive back at The Camp, the Delinquents are worried about the Grounder having escaped. Bellamy announces that they have been scared of the Grounders for too long because of their knives and spears and he is done being afraid. Together, they show the camp the rifles. Clarke warns them they will have to be prepared to give them up to the Ark Guard when the drop ships come, but until then, they’re going to help keep them safe. Bellamy tells them they will start training in the morning so that if the Grounders attack, they will be ready. Finn is not happy about the rifles in camp. Later, as Bellamy tries to make amends with Octavia, Clarke approaches the two telling Bellamy it is time to talk to Jaha. Back in the communications tent, Bellamy and Clarke face Chancellor Jaha through a video chat. Before Jaha says anything, Clarke defends Bellamy and asks for his crime to be pardoned. Jaha explains that it is not that easy. Bellamy tells Jaha it is that easy if he wants to know who on the Ark wants to him dead. Jaha then pardons Bellamy Blake for his crimes, much to both of their relief.
Later that night as Clarke checks on Finn’s wounds, Finn vocally disapproves of bringing guns into camp. Finn does not want the guns in camp because he does not trust Bellamy and Clarke cannot predict what Bellamy is going to do. Clarke tells Finn she trusts Bellamy, shocking him and he tells her she is wrong to trust Bellamy. He also tells her she and Bellamy are leading the Delinquents down a dangerous road and wishes Clarke would have talked to him first. Clarke, however, replies that she wishes Finn would have talked to her about a lot of things but he didn’t. Just then, Raven enters the tent and Clarke quietly leaves while Raven looks after her.
In Unity Day, at The Camp, the Delinquents are listening in through remote broadcast as Chancellor Jaha gives a Unity Day Celebration speech on The Ark about how everyone will be on the ground next year. Clarke walks up to Finn and he tells her how Unity Day is a lie because the Ark only came down after the 13th station was blown up. Clarke tells him that peace came out of that violence but Finn questions whether there even needed to be violence. Later, as the Delinquents are drinking and celebrating. Clarke approaches Bellamy and he tells her he has security covered in case Lincoln comes back with other Grounders. He tells her she could use a drink and reminds her that in two days, her mom is coming down and the party is over. Clarke agrees and tells him he also deserves some fun. She leaves and begins playing drinking games with Sterling, Fox, and Miller. Finn interrupts and pulls Clarke away. He tells her he set up a meeting with the Grounders. He tells her he thinks they can do better this time around and Clarke says they need to bring backup. Finn says the terms were no weapons. Clarke agrees and tells him she will meet him at the gate. She then seeks out Bellamy and tells him about the meeting, asking him to go as her backup without telling Finn.
As Clarke and Finn walk through the woods, Clarke stops to check his stab wound. She tells him she's just trying to keep them alive. As they continue on to the meeting place, Clarke leaves behind a trail that Bellamy, Raven, and Jasper are following. When they arrive at the meeting place on a bridge, Octavia is there waiting for them. Clarke realizes it was Octavia who set it up and Octavia tells Clarke that she trusts Lincoln. Lincoln comes running up shortly thereafter and catches Octavia in a hug, which Bellamy, Raven, and Jasper witness from their hidden location under the bridge. Bellamy gets Lincoln in his sights just as the Grounders arrive on horses. Finn gets upset when he sees they are carrying weapons. Clarke crosses the bridge and meets Anya in the middle and offers her hand. Anya does not take it. Anya tells Clarke that she started a war she doesn't know how to finish when she burned a village to the ground with the flares they set off trying to alert the Ark they were alive. The Delinquents invaded their land and sent an armed raiding party to capture and torture one of their people. All acts of war. Anya asks Clarke if it's true that more warriors are coming down and Clarke tells her that yes, there will be the Ark Guard, but also farmers, doctors, and engineers. Anya asks if Clarke can promise that they will agree to the terms she and Clarke agree on but Clarke cannot promise that. Meanwhile, Jasper spots Grounders in the trees and shouts at everyone to run as he starts shooting at them. The Grounders shoot arrows back at the Delinquents. Anya takes out her knife and is about to stab Clarke when Bellamy shoots her in her arm. Finn runs across the bridge to drag Clarke to safety. Lincoln tells them to keep running till they get back to their camp.
After they return to Camp, they start blaming each other for everything. Finn blames Clarke for bringing guns and for not trusting him, blames Raven for being too preoccupied making bullets, and blames Jasper for firing the first shot. Clarke blames Finn for trusting the Grounders. Raven blames Finn for not telling her about it. And Octavia blames Jasper for ruining everything before she walks away. There is a sonic boom and Clarke and Bellamy look up to witness the Exodus ship coming down a day early, much too fast, and without a parachute. An explosion is seen in the distance and Clarke crumples in grief when she realizes her mother just died.
In I Am Become Death, Clarke, Bellamy, and a group of Delinquents investigate the Exodus drop ship crash. There are no survivors. Raven tells Finn to help her find the black box to explain why the ship crashed. Bellamy warns everyone to keep on the lookout for Grounders in retaliation for the Unity Day bridge battle. Clarke discovers a pink, smelly liquid that Raven tells her to get away from because it is highly explosive hydrazine. She demonstrates by throwing some and creating a small explosion and tells Bellamy to clear the area.
When they return to The Camp, they discover Murphy has returned after having been banished. Murphy tells them he was running from the Grounders. Bellamy starts to point a gun at him for returning and Finn intervenes, telling Bellamy that Murphy might be able to tell them things about the Grounders. Bellamy tells Finn to get out of his way but Clarke tells him Finn is right. She sees that Murphy's fingernails were torn off and that he was tortured. Bellamy wants to know what Murphy told the Grounders and Murphy admits, "everything." Clarke tells Bellamy to let Murphy get better and then force him to leave again and if he doesn't, then they kill him. Clarke heads to the Communications tent and runs into Raven inside. Raven tells her she still has not been able to get back in contact with The Ark since the Unity Day Celebration and she has a bad feeling. As she is telling Clarke she is sorry about her mom, Clarke's eyes begin to bleed. Connor then calls out for Clarke because he's coughing up blood. As more Delinquents begin coughing and bleeding, Clarke tells Raven to stay away.
In the drop ship, Murphy is puking up blood. Clarke asks him how he escaped and he tells her they forgot to lock his cage so he took off. Clarke realizes the Grounders purposefully let him go just as Bellamy enters the drop ship, asking what is happening. Clarke tells him it is biological warfare. Bellamy blames Murphy but Murphy tells them he did not know. Derek starts seizing before collapsing and dying. Clarke orders a quarantine. She asks Connor who else was with them when they found Murphy and Connor admits it was Octavia. Bellamy goes to check on Octavia and brings her to Clarke. Clarke tells Bellamy that she needs to quarantine her. Once Bellamy leaves, Clarke tells Octavia that she needs to talk to Lincoln to get the cure. Another Delinquent dies from the sickness and Bellamy orders everyone back to work. He checks in with Clarke at the drop ship to see if she needs anything and she jokes about needing some medicine. Bellamy then calls into the drop ship after Octavia and Clarke has to admit that she sent Octavia to Lincoln for a cure. Bellamy storms off and tells a Delinquent to get out of his way. The Delinquent turns and his eyes are bleeding. Everyone starts to panic as more kids fall sick. Clarke fires a gun into the air to get everyone to settle down. One Delinquent orders Clarke back in the drop ship and Bellamy knocks him in the face before telling Clarke that her quarantine isn't working. Clarke starts to collapse and Finn rushes over to catch her. Octavia arrives just then with the announcement that there is no cure and the Grounders attack at dawn. Octavia then helps Finn get Clarke into the drop ship. Murphy stands up and offers his spot because he's already starting to feel better. Octavia offers Clarke some water and Clarke asks her to help with the sick and Murphy volunteers to help as well. Clarke then tells Finn to flee camp with anyone healthy enough to go with him.
Later, Bellamy wakes up after having also fallen sick. He looks for Octavia and Clarke as Murphy approaches him with some water and Bellamy pushes him away. Clarke comes over and gives Bellamy some water. He asks where Octavia is and she tells him Octavia was up all night tending to the sick. Bellamy tells her he thinks they should get everyone inside the drop ship and lock them up because sick is better than dead by the Grounders if Finn and Jasper don't pull off their mission to blow up the bridge. They do pull it off and a massive explosion is seen and heard all the way back at the Camp. Bellamy is impressed they did it and Clarke quotes Oppenheimer. Jasper and Monty return to the Camp to cheers and applause while Finn drags in Raven (who has now also fallen sick). Clarke gets her set up in the drop ship and leaves Finn with Raven. She nods at Murphy in thanks for his help as she leaves the drop ship. Bellamy finds Clarke outside the wall at the graveyard and Clarke comments how there are 14 graves. Clarke tells Bellamy that Murphy was right about the bridge and Bellamy warns her about the so-called "Mountain Men."
In The Calm, Bellamy approaches Clarke outside The Camp walls and asks if she thinks the bomb on the bridge scared the Grounders off. She says no and he tells her that Jasper thinks he might be able to make some more gunpowder and Raven can make some landmines. There is still no word from The Ark since the Unity Day blast and they wonder if everyone ran out of air. Clarke does not think anyone is coming down to save them. Later, after a fire burned down the Camp's smokehouse, Clarke asks what happened and Bellamy explains that Del built the fire up too much because Octavia told him it was a bad idea. Clarke tells him they need to go hunting because they can't defend themselves if they are starving. Bellamy tells the Delinquents to go out in groups with one Gunner in each group and to use the bullets for the Grounders but the spears for their food. Myles asks Clarke if she would like to go hunting with him and she agrees. Finn then asks if she wants to go hunting and she says no just as Myles walks up and assumes Finn is coming and they all leave to go hunting together. As they are looking for prey to hunt, Myles is chatting when Clarke tells him to be quiet. Finn realizes the tracks they had been following were made by Grounders and they are the ones being hunted just as Myles is struck down by an arrow in his leg and one in his chest. Finn tells Clarke they have to leave Myles just before he is hit over the head by a Grounder. The last thing Clarke sees is Anya.
Clarke and Finn are led into a room and Anya enters. She releases Clarke as another Grounder reveals a mortally injured Tris. She tells Clarke to help her; otherwise, Finn will die. Clarke asks Anya why she thinks she can save Tris. Anya says that Lincoln had told her about Clarke's medical expertise and since their healer is gone, they need Clarke or Finn dies. Clarke asks what happened and Anya tells her that Tris was on the bridge when the bomb exploded. Clarke asks Finn for help on lifting Tris up and listens to her lungs. She realizes that Tris is drowning and she needs to relieve the pressure. She asks for some tube and Caliban finds some for her. Clarke makes an incision in between Tris' ribs and inserts the tube. Anya returns to the room just then and asks what Clarke has done, shoving her out of the way to get to Tris' side. Anya tells Clarke that Tris is hot and Clarke says that she's probably septic and needs real medicine. Clarke asks how Anya could send a little girl into battle and Anya tells her that Tris was her Second and it's how they train them to be warriors. Tris starts gasping and Clarke says she needs a transfusion and asks for supplies. Finn sharpens a needle for Clarke and they get a syringe ready to do the blood transfusion but Caliban and Anya refuse to let her take their blood. Finn offers his blood up instead and Clarke preps him. She then looks for a vein on Tris and can't find one before Finn lets her know that Tris is dead. Anya takes out a knife and cuts a braid of hair from Tris' head before gesturing to one of her warriors to remove Tris' body. She then tells another warrior to take Finn and kill him. Caliban tells Clarke that if she proves her worth, she'll be welcome with them because their healer is gone. She asks if she will be able to visit the Delinquents and Caliban tells her after tomorrow there won't be anything to go back to. Clarke asks about the marks on Tris' and Lincoln's shoulders and Caliban tells her each scar is a kill in combat, meaning Tris had already killed five people. Caliban shows her the kill scars on his chest, saying half of them were after he hurt his knee. Clarke then kicks him in his knee and uses a scalpel to slice his throat open. As he is gurgling to death, Clarke covers his mouth to quiet him and watches as he dies. She then takes off into the forest and begins running back to camp. As she is running through the woods, she steps in a Grounder trap and is yanked upside-down and pulled high into the tree-tops.
In We Are Grounders (Part 1), Clarke is Anya's hostage at a campfire in the woods. Tristan arrives and Anya asks Tristan if the Commander sent him and he tells her that her unit is now his. He brought his Rangers to complete what Anya failed to do, starting with Clarke. Just then, a signal fire is spotted in the distance, announcing Reapers. Tristan tells Anya to take care of Clarke and Anya asks one of her warriors if Finn is dead. The warrior nods and Anya tells him to finish Clarke as well and catch up with them when he is done. Clarke tries to run away and he grabs her chains, yanking her back hard enough that she hits her head and is knocked unconscious. When Clarke awakens, she is riding in front of a Grounder on a two-headed horse through the woods. They arrive at the hilltop signal fire and she is let down and released. Finn comes out from behind the fire and they hug. The Grounder removes his mask to reveal himself to be Lincoln, who had to kill one of his own people to save them. They see the signal fire that Anya lit in response goes out and Lincoln warns them it means that Anya knows Clarke and Finn are free and Lincoln tells them to run. They reach the Reaper tunnels just as Anya and Tristan arrive. Anya shoots arrows into the mines after them. Tristan tells Anya to let them go because they know where they are going if the mines don't kill them first.
In the Reaper tunnels, Lincoln lights a fire to make a torch and tells them they have to keep moving. Lincoln was hit by one of Anya's arrows and Clarke offers to help him with it. She asks Lincoln why he is helping them and pushes the arrow all the way through his side so he can break off the arrowhead and pull the arrow out. Lincoln tells them he is helping them because what his people are doing is wrong and Clarke cauterizes his wound for him. Lincoln then leads Clarke and Finn back toward The Camp by using a map he took off an enemy. Clarke hears noises ahead and Lincoln says it is the Reapers. They reach a tunnel blocked off by a group of Reapers and they see a mine cart filled with dead bodies. Lincoln gives Finn his book and his sword for Octavia and tells them to wait for him to lead the Reapers away and then they will need to run through the tunnel to get back to camp. He tells them to get all of the Delinquents out of there before Tristan's scouts arrive and tells Clarke to take the Delinquents to Luna's clan in the East. Lincoln then attacks a Reaper and kills him, making all of the other Reapers chase after him. Once the tunnel is empty, Clarke and Finn proceed down it with Clarke stopping at the mine cart. She pulls away a tarp and reveals a barely alive Grounder, reaching out for her help and realizes they are all still alive. A Reaper attacks them and has Finn by the throat when Finn grabs a rock and bashes the Reaper's head in. They make it out of the Reaper tunnels and stop by a stream where Finn begins washing the dead Reaper's blood off his hands. Clarke tells him he did what he had to do. He tells her he is in love with her and she tells him she is sorry, but he broke her heart and she can't. They hear a loud explosion coming from the camp and rush off.
When they arrive at the Camp, Miller calls for the gate to be opened to let them in. Finn tells everyone that it is time to pack because they need to leave. Bellamy asks where they would go that it is safer behind the walls of the camp. Finn tells them about the tribe to the east. Bellamy tells the Delinquents that they built this home from the ground and that now they are on the ground, they are all Grounders now. Clarke says that Bellamy is right that their camp is safe but, if they stay, they will die and tells them to pack only what they can carry. As the Delinquents disband, Raven appears from underneath the drop ship after having been shot by Murphy. Clarke has Finn take Raven into the drop ship while Bellamy tells Clarke he thinks she is making a bad decision and leaders need to do what they think is right, not what is popular. Clarke tells him she is as the Delinquents prepares to leave.
In We Are Grounders (Part 2), in the drop ship at The Camp, Clarke cauterizes Raven's gunshot wound caused by Murphy). Bellamy flips through Lincoln's journal and comes to a drawing of a Reaper and asks if the Reapers might help them fight the incoming Grounders. Clarke tells him it is not an option. She then tells Raven that she cannot walk with the bullet still inside her and Finn goes to get a gurney. Bellamy calls Finn a coward and Clarke interrupts, telling them it is time to go. Finn leaves and Clarke tells Bellamy she needs Bellamy with them because the Delinquents are willing to fight and die for Bellamy. Outside, on their way out of the Camp, Bellamy mentions there are eighteen dead and Clarke tells him there are eighty-two alive and they did good.
After the Delinquents have begun their march to the sea, Octavia brings everyone to a halt, sensing something. A blade comes flying out through the trees and embeds in Drew's head. Jasper screams out, "Grounders!" and all of the Delinquents flee back behind the walls of the Camp. Clarke realizes that they are doing exactly what the Grounders want them to do: returning to the camp so that they are back in place for the assault. With the Grounder scouts already outside, Clarke realizes it is not safe for them to try and leave camp again and they need to stay and fight.
Later, inside the drop ship, Bellamy and Raven tell Clarke and Finn that the main entrance has been booby-trapped with landmines and that Raven has built a couple of grenades. Bellamy plans to keep the Grounders at bay using guns, grenades, and the landmines to hold the gate. Raven notes that if the Grounders get through the gate, they will have to hide inside the drop ship and close the door and pray. Clarke suggests using the remaining rocket fuel from the drop ship, to fire its rockets once the Grounders have surrounded the drop ship, which would burn the Grounders alive. Raven says she can do it. Clarke and Finn head underneath the drop ship, looking for its ignition system, when Raven reveals that she cannot feel her legs anymore. Clarke discovers that the bullet is in Raven’s spine and that she is bleeding internally. Finn suggests going to Lincoln's cave to get some of the coagulant stuff the Grounders use and leaves to go get it. Clarke continues searching underneath the drop ship for an orange wire that is the drop ship's ignition. When Clarke finds the wire she discovers it to be broken. Raven asks Clarke if she knows how to splice a wire. Over the walkie-talkie, Jasper informs Raven and Clarke that the landmines are working. Raven realizes Jasper can splice a wire. Clarke calls for Jasper to get to the drop ship. Jasper joins Clarke underneath the drop ship and Clarke asks Raven to repeat the direction but receives no response. When Clarke goes to check on her, she sees Raven has lost consciousness. When one of the gunners announces through the walkie-talkie that the Grounders have broken through, Clarke tells Jasper to finish the wiring of the ignition system while she goes outside to check out the situation. She tells the gunners they need more time and to stay at their posts and hold off the Grounders while the others get inside the drop ship. A bright light suddenly lights up the night sky, distracting everyone on the ground. Clarke realizes that it is the Ark, entering the atmosphere.
Back inside the drop ship, Clarke injects Raven with the coagulant Finn returned with. Miller comes in and informs them that the Grounders are taking down the gate. Jasper announces that he is ready with the ignition system. The Grounders breach the gate and Clarke yells at the Delinquents outside to get inside the drop ship. She spots Bellamy returning through the secret entrance and watches as he picks up a gun to go after Tristan but there are no bullets. Tristan begins attacking him and Finn grabs a gun and runs to Bellamy's aid. Clarke reluctantly has to leave the two of them fighting Tristan as she goes inside the drop ship and closes the door as the Grounders breach the Camp walls. Anya, however, quickly jumps over the door and is locked inside with the Delinquents. Anya stands, ready to fight the Delinquents with two blades. Clarke tells Jasper to push the button for the ignition but it doesn't work. Outside, the Grounders are making their way up the sides of the drop ship while Anya begins to attack inside the drop ship. She is easily overpowered by the numerous Delinquents as Clarke stops Miller from killing Anya by reminding them they are not Grounders. Jasper realizes he forgot the magnet and reroutes the connection through a magnet, blasting the drop ship's rockets, incinerating the Grounders outside.
The Delinquents and a bound Anya leave the drop ship to find the ashes and skeletons that were a result of the rockets’ ignition. All of a sudden, several red smoke grenades are thrown over the camp’s walls as Anya fearfully says, “Mountain Men.” The red smoke begins to knock out the Delinquents and Anya. Clarke's last image is of several men in gas masks and military outfits with laser-sighted rifles entering the camp and a Mountain Man pointing his gun and laser at her. When Clarke awakens, she is in a completely white room where she is being monitored. She pulls out her IV and goes to the locked door where she sees Monty banging on the door of a similar room across the hall but his door is also locked. A plaque on Monty’s side of the hall says “Mount Weather Quarantine Ward”.
In The 48, Clarke breaks free of her quarantine room in Mount Weather and threatens Maya with a piece of broken glass, demanding she takes her to see Monty. The frightened girl screams "you'll get me contaminated!" Clarke continues to threaten her as Maya leads her into a dining hall filled with many people eating. A woman looks over and sees Clarke holding the girl hostage and screams out in fear that there has been a containment breach, causing panic as everyone starts running away from Clarke. Clarke looks around at the chaos she's just caused and asks "where am I?" in confusion. Clarke is later introduced to Maya, the girl she threatened earlier, who says she won't press charges. Clarke is then taken to a bed in the medical ward. Dante Wallace says he knows she's the leader (like him) and also a painter (like him). He tells her they're not prisoners and has a wardrobe brought out for her to choose from and leaves her to get dressed. She picks up a shoe and snaps the heel off, concealing it up her sleeve as a weapon. When Dante takes her to the other 47 Delinquents in Mount Weather, he stops her and tells her to give him the heel and she does so. She then discovers from the Delinquents that Raven, Bellamy, and Finn aren't there.
Monty and Jasper are enjoying their food when Clarke comes in. She says it's weird that they gave them a map without any exits. She also refuses to eat their food. They dismiss her as being paranoid. Jasper goes to talk to Maya and Clarke also comes over and apologizes to Maya before leaving. Maya realizes that Clarke had stolen her access card and she and Jasper start to chase after Clarke. An alarm goes off and Clarke sees guards running towards her. She runs and makes her way through a restricted area, locking a door behind her and breaking the lock. She finds herself at a set of stairs leading up. Once she gets to the top, she finds a massive, sealed door. She figures out how to unlock the door and is about to pull the lever that will open the door when Jasper and Maya appear and beg her not to open it. If she does, then all the Mountain Men will die from radiation exposure. Maya even goes so far as to get a gun out and is prepared to kill Clarke if she opens the door. Jasper pleads with her, telling her that she saved lives when she pulled the lever that fired the rockets and to not make a mistake by pulling this lever now. Clarke allows herself to be taken into custody.
After Clarke is arrested, she is taken to Dante where he is busy painting the outside world. He tells her how he got to see the outside once when he was seven for five minutes. The Mountain Men saw the first of the Outsiders and thought the earth was survivable but 54 Mountain Men died within the week. He also tells her that they have found no survivors from either the drop ship or the Ark but he'll keep searching. He asks her to give herself time to grieve and that he doesn't want her to try leaving again. Later, in the Delinquents' dorm, she opens an envelope addressed to her with a painting set from Dante. They go out to the Mess Hall and Clarke allows herself to finally eat their food.
In Inclement Weather, the Delinquents are having a good time in Mount Weather and Jasper tells Clarke he likes it there. Miller returns from medical and joins the rest of the Delinquents in their dorm on Level 5. Jasper and Maya Vie begin to flirt with each other when an alarm goes off and Maya tells Clarke it is for someone needing medical attention. Clarke and Jasper follow Maya to medical where people are donning protective gear. Clarke snatches a key card and runs out, saying it is not dangerous for her. She finds a man (Sgt. Shaw) lying dead from an apparent gunshot wound just as another person (Sgt. Langston) is brought in with radiation burns across his body.
Clarke confronts the president of Mount Weather, Dante Wallace, about Sgt. Shaw's gunshot wound because Grounders do not use guns. Dante takes her to Medical where Dr. Tsing shows her Sgt. Shaw's body and explains it was caused by an arrow that was pushed out in the field and she brings an arrowhead out for Clarke to inspect. Clarke tells Jasper that she thinks the Mountain Men are lying and are trying to make the Delinquents think that there are no Sky People outside the mountain. Jasper tells Clarke the only threat to their safety currently is Clarke.
Later, Clarke is on Level 5 with the rest of the Delinquents, studying the map of Mount Weather before scrunching it up and throwing it away. She sees Sgt. Langston, the man with the radiation burns appear, however, he is already almost completely healed. She overhears that he still needs another treatment and decides to get back into Medical by re-opening her arm wound. After Clarke has been treated again for her wound, she gets up from her bed in Medical and begins to snoop around. She follows the tubing used for the radiation dialysis and discovers it leads into another room. She climbs through a vent in the wall and discovers Grounders hanging upside down with their blood being circulated through the Mountain Men. There are hundreds of cages in the room and locked away in one of them, she finds Anya.
In Reapercussions, Clarke tries to help Anya out of her cage in the Harvest chamber in Mount Weather. After ripping off a pipe, Clarke manages to break the lock on Anya's cage. Dr. Tsing walks in and Clarke is forced to hide inside the cage with Anya. The doctor observes the group of Grounders in cages before backing away and leaving the room. After the doctor leaves, Clarke helps Anya out of her cage and they go through a door marked "End Containment Area" that abruptly shuts behind them. An alarm goes off and the ground opens beneath them, dumping them into a mining cart filled with bodies. Clarke manages to get out of the cart and spots piles of clothing. She tells Anya to get dressed and that they need to escape. Anya tells Clarke that she will not leave her people behind. Clarke explains that the Mountain Men have guns and they need to find help to save both of their people. Anya tells her there is no "we" just as Reapers come down the tunnel. They jump back into the cart and pretend to be dead. The Reapers toss a couple more Grounder bodies on top of them before pushing the cart down the tracks. When the cart stops, one of the weakened Grounders is taken out and fed on. With the Reapers distracted, Clarke is quick to escape the cart. Anya remains behind, realizing that one of the Grounders is still alive. Anya takes the Grounder's head in her hands and says in Trigedasleng, Yu gonplei ste odon ("Your fight is over") before breaking his neck. Anya escapes the cart and the two flee.
In the Reaper tunnels, Clarke gets frustrated because they are in a maze. Anya asks what the Mountain Men were doing to her people. Clarke explains that they were using the Grounders' blood to heal the Mountain Men from radiation exposure. Anya starts to go back toward the Reapers and Clarke tries to stop her, telling her the best way out is to work together. While she is talking, Anya takes off and goes her own way, leaving Clarke to fend for herself. Clarke is soon surrounded by Mount Weather guards. As they're about to bring her back into Mount Weather, Anya attacks and Clarke realizes that if they rip off their masks, the Mountain Men are exposed to radiation. Clarke and Anya are able to get free and take off running as more Mountain Men chase after them. They arrive at the end of a tunnel that opens out into the side of Philpott Dam. Anya jumps off the dam and into the waters below. Clarke turns toward the Mountain Men and appears to be surrendering before she turns and takes a running jump off the ledge and over the dam into the water below. Anya pulls Clarke out of the water and waits for her to regain consciousness before telling Clarke that she is now Anya's prisoner. Anya then knocks Clarke over the head with a rock.
In Many Happy Returns, Anya has taken Clarke captive and is bringing her back as a prisoner when they are discovered by the Mountain Men who shoot tranquilizers at them. Clarke and Anya take off with Clarke grabbing one of the tranquilizer darts that missed them. They make their way through the woods, however, the Mountain Men are easily catching up to them. Anya blames Clarke for being loud and smelling too much and slathers her in mud to try to cover her scent. As the Mountain Men continue following them, Anya keeps blaming Clarke. Clarke realizes that they are not really following them; they are tracking them. She tells Anya to look for a bump under her skin and Anya finds one in her forearm. Clarke asks Anya to untie her so she can remove it for her but Anya ignores her and tears out the tracking device with her teeth. They continue wandering through the woods when Clarke jabs Anya with the tranquilizer dart, telling her that she can find her way home from there and Anya is now her prisoner.
Clarke manages to drag Anya back to the drop ship and spots the faded and unrecognizable writing on the side of the drop ship with only her name clearly legible. Anya wakes up from the tranquilizer and the two engage in a bloody, brutal, long-lasting brawl until Clarke finally gets the upper hand. As she is about to kill Anya, she spots a glinting light far in the distance and sees a weather balloon high in the sky and realizes other Sky People are out there still. As Clarke and Anya approach Camp Jaha, Clarke tells Anya that their only chance against Mount Weather is if they fight together. Anya says the Commander was her Second and that she can get an audience. They part ways with Anya heading back to her people when a gunshot rings out and Anya falls over. Clarke runs to her side and tries to help Anya, however, Anya ends up dying.
Clarke wakes up after having been asleep for 10 hours and goes outside and sees Raven and they hug. Bellamy, Octavia, Monroe, and Mel arrive at Camp Jaha and Clarke runs to greet them, giving Bellamy and Octavia hugs. Bellamy tells her Finn is still out looking for her. Abby tells Clarke that Murphy and Finn are not a priority and they are not going after them. Bellamy is outraged that Abby would just abandon them now that she has Clarke back and offers to go on his own instead. She refuses to allow it and Jackson pulls Abby away to deal with an emergency in Medical. Bellamy and Clarke meet Raven at a section of the gate surrounding Camp Jaha. Octavia arrives and they gear up. Raven then has Wick shut down the electricity to that area of the fence and Bellamy, Octavia, and Clarke head out into the woods to go after Finn and Murphy.
Later that night in the woods, Bellamy is keeping watch over the campfire while Clarke and Octavia sleep. Clarke wakes up and they discuss her closing the drop ship door with him telling her that it had to be done. He then tells her how Finn has not been the same since Clarke disappeared and he let Finn go with Murphy and two guns. Clarke tells him she was sure it had to be done, too. They discuss getting the Delinquents out of Mount Weather and Octavia wakes up and makes them include Lincoln in their mission. Octavia leads Bellamy and Clarke to the Abraham Lincoln statue near Lincoln's village. She breaks down and begins to cry as she tells Bellamy about how the Reapers took Lincoln and she couldn't save him. They then hear machine gun fire and race off toward the village, arriving to see Finn massacring the people of Tondc. It is only when Finn spots Clarke that he stops shooting. As Clarke and Bellamy approach, Finn tells Clarke, "I found you."
In Fog of War, two days after the massacre at Lincoln'svillage, Clarke and Bellamy are sitting outside in the bar area of Camp Jaha. They are reviewing Clarke's map of the tunnels through Mount Weather and are discussing an action plan to get the Delinquents out. Finn and Murphy approach and Clarke admits she hasn't talked to Finn since they got back. Bellamy leaves to get drinks and Finn asks about the Mount Weather plan. Murphy tells Clarke they were cleared because the pardon the delinquents received for being sent to earth includes their time on the ground. Clarke still won't really talk to Finn so Finn leaves. Raven arrives and tells Murphy to leave before she reveals to Clarke that she figured out why they had not heard from any of the other Stations: Mount Weather has been jamming their signals. Major Byrne witnesses the conversation and tells Abigail Griffin. Later, while Raven is explaining to Clarke how Mount Weather has been jamming their signals and even crashed the Exodus drop ship that came down on Unity Day, Abby interrupts them and tries to stop them. Clarke and Raven convince Abby that they need to take down the radio tower on Mount Weather so they can find any other Ark survivors to help build their army. Abby tells Byrne to stay behind and guard the camp because Abby will be going with them to Mount Weather.
Clarke, Abby, Raven, and several other Sky People and Camp Jaha Guards are hiking to Mount Weather to take out the radio tower. Clarke and Abby discuss Finn's situation and how the Council cleared him. They then stop to survey Mount Weather and look for the radio tower. Abby realizes that Bellamy and Octavia have taken off on their own to find another way into Mount Weather. She sends Sgt. Scott and two other Ark Guards off to go find them. Finn volunteers to go after them, too, but Clarke stops him. Finn gets upset because of the way everyone is acting toward him since the massacre and storms off with Clarke following after. Acid Fog suddenly starts rolling toward them and Clarke and Finn take off for the bunker. When Clarke and Finn get to the bunker, Clarke sees Delano's corpse still sitting there. Finn covers it up. They discuss the awkwardness between them and Finn gives Clarke back her father's watch that had been around the dead Delano's neck. As the Acid Fog lifts, Clarke tells Finn that she doesn't know who he is any more and he says that he doesn't either. Once Clarke and Abby meet back up at Camp Jaha, Abby tells Clarke that they decided against blowing the radio tower because they're not sure if there are any Ark survivors but they are sure that there are 47 Sky People trapped in Mount Weather. Just then, Jaha approaches and tells them he has a message from the Commander: "leave or die. We have two days."
In Long Into an Abyss, with the threat of the Grounders attacking in retaliation for the massacre in Tondc, Abigail Griffin tells everyone at Camp Jaha that yes, the Grounders have threatened them but they haven't made any decisions yet. Jaha tells everyone to pack and be ready to leave if they need to. He will lead them across the Dead Zone and to The City of Light. Clarke interrupts and asks about the Delinquents still trapped in Mount Weather. Abby tells everyone that no decision has been made yet and they should all report to their station supervisors. As the meeting is breaking up, Bellamy grabs Clarke and tells her she needs to bring a Med kit and go with him to the drop ship.
When Clarke arrives at the drop ship, she sees Octavia and a chained-up Lincoln who had been turned into a Reaper by Cage. Clarke inspects Lincoln and discovers needle marks on his neck. Lincoln manages to break free and begins attacking everyone until Octavia is able to knock him out again. After Lincoln has been restrained again, Clarke tries to remove the bullet from his leg where Octavia had shot him. Octavia tries to give Lincoln some water and he thrashes at her, upsetting her. She goes outside to get more water but returns with Nyko, Lincoln's friend, instead. Lincoln begins seizing and Nyko kneels down with a vial to give to Lincoln. As he's holding the medicine over Lincoln's lips, he says, Yu gonplei ste odon ("Your fight is over"). Clarke recognizes the words from when Anya had said them and stops him from mercy-killing Lincoln. Nyko tells her that death is the only way just as Finn appears to warn them that everyone in Camp Jaha is about to leave. When Nyko sees Finn, he attacks him and strangles him for slaughtering his village. Clarke uses an Ark Guard'sstun stick to knock Nyko off Finn just as Octavia realizes that Lincoln has stopped breathing. Nyko watches in awe as Clarke gives Lincoln chest compressions and gets him breathing again. Clarke realizes that the Grounders have been trying to bring Reapers back but have never been able to do so and she can use that to her advantage to stop the attack. Clarke goes down to the second level of the drop ship where Finn has been waiting alone. Finn tells her that even if Lincoln lives, he won't be the same. Clarke tells Finn that both he and Lincoln are saveable.
In Camp Jaha, everyone is preparing to evacuate when Clarke arrives and tells Abby that she knows how to stop the Grounder threat. In the distance, lights start to appear in the darkness of the night and everyone realizes the Grounder army has arrived. Abby then decides to head back to the drop ship to save Lincoln while Clarke goes to talk to the Commander. Clarke approaches the Grounder camp outside Camp Jaha and is stopped by Gustus who warns her he'll slit her throat at the slightest provocation. Clarke enters the Commander's tent and meets Commander Lexa who is seated on a throne with Indra on one side. Clarke tells Lexa about Mount Weather and about how she and Anya escaped together and presents Lexa with a braid from Anya's hair. Clarke lies that they can turn the Reapers back into Grounders because she has done it with Lincoln. Lexa demands for Clarke to prove it.
Clarke leads Lexa and her Guard through the carnage outside the drop ship while Abby is trying to get Lincoln breathing again. Abby finally gives up and says that Lincoln is gone but Octavia refuses to believe her and continues chest compressions. Clarke and everyone else enters the drop ship at that moment and they are at a standstill with everyone going for their weapons. Abby picks up the shock baton and holds it in front of her before using it as a defibrillator on Lincoln, shocking him twice before he starts breathing again, much to the Grounders' surprise and the Sky Peoples' relief. Later, back in Lexa's tent outside Camp Jaha, Lexa tells Clarke that she is willing to have a truce as soon as Finn dies.
In Spacewalker, Clarke arrives at Camp Jaha after speaking with Lexa, the Grounder Commander, who has ordered Finn's death for the massacre of Tondc before their truce with the Sky People can begin. Most of the Sky People want to give Finn up to the Grounders, especially because he wasted three months of oxygen on The Ark for the spacewalk that got him imprisoned. Clarke blames Murphy for what happened at Tondc even though Murphy had tried to stop Finn. He tells Clarke to blame herself since Finn was looking for her. Clarke visits with Lincoln who is recovering from being a Reaper. Abigail Griffin asks Lincoln how to negotiate with Lexa in order to save Finn but he says there is no way out of it and Finn must die. Octavia asks what would happen to him and Lincoln tells them that because Finn killed 18, he will suffer 18 deaths as a result. Clarke asks how he can say that about his friend and Lincoln tells Clarke that some of the dead Finn had massacred were Lincoln's friends, too.
Clarke finds Finn gathering supplies to leave. He tells her he is in love with her and he has done everything to keep her safe. He asks her to forgive him and Clarke asks him not to leave. They then hear the Grounders chanting loudly, Jus drein jus daun! ("Blood must have blood!"). Clarke and Finn leave Camp Jaha and are headed to the drop ship when they are attacked by a Grounder who knocks Clarke out. Finn pulls a gun on the Grounder and begs the Grounder to leave so Finn doesn't have to shoot him. Finn arrives at the drop ship, carrying an unconscious Clarke. Bellamy and Murphy take care of Clarke while Raven tries to comfort Finn. Clarke wakes up and Finn tells her he thought she was dead because of him. Clarke tells him he is not defined by the things he has done. Bellamy shouts a warning to them that the Grounders have arrived and they're surrounded. Raven wants to give up Murphy instead of Finn because Murphy was also at the village. Finn steps between Raven and Murphy and tells them they need to stay and defend the drop ship. He instructs Murphy to go upstairs and watch the back while he takes the lower level of the drop shop and Bellamy, Raven, and Clarke will take the front gate. Finn then climbs out the bottom of the drop ship and Clarke, Raven, and Bellamy watch the front gate as they witness Finn step out in front of them and surrender himself to the Grounders.
Back at Camp Jaha, Clarke, Raven, Bellamy, and the rest of the Sky People watch as the Grounders start setting up for Finn's execution. Abby says there is nothing to be done. Clarke, Raven, and Bellamy then meet up at Raven's Gate where Raven gives Clarke a knife so Clarke can kill Lexa because Raven owes Finn her life. Clarke approaches Lexa's tent and Indra stops her with a spear. Clarke presses against the spear, drawing blood. Lexa tells Indra to let Clarke through. Clarke begs Lexa to show how powerful she is by having mercy and that Finn killed those people for her. Lexa tells Clarke that Finn will die for her, then. Clarke asks if she can say goodbye and Lexa allows her to. Clarke walks over to Finn and hugs him, telling him she loves him and that he will be okay. He says, "thanks, Princess" and she steps away from him to reveal that she had killed him with the knife Raven gave her. Lexa tells her warriors that it is done and keeps them from attacking. Raven screams and crumples in hysterical grief while Bellamy catches her and holds onto her.
In Remember Me, Clarke is alone in Lexa's tent as she tries to scrub Finn's blood off her hands after having mercy-killed him. Abigail Griffin enters and hugs Clarke as she cries. Marcus Kane enters with Gustus behind him. Gustus tells Clarke the Commander is ready to talk. Lexa tells Clarke that Finn's body will be given to the people of Tondc since Clarke denied them their justice. Kane and Abby get into a disagreement with Indra over this but Clarke agrees to it. She says once it is done, they will then talk about getting all of their people, both Sky People and Grounders, out of Mount Weather. Clarke tells Abby that if the truce does not hold, then she killed Finn for nothing and walks away. Abby tells Kane that the Grounders are being led by a child and he tells her, "so are we." Clarke approaches Raven who is kneeling over Finn's body and tells Raven she is leaving with the Grounders and Raven needs to work on the radio. Raven tells Clarke she is coming, too and will bring the radio. Clarke then gestures to the Grounders to take Finn's body away. As they are doing so, Clarke sees Finn's eyes open and stare at her.
On the walk from Camp Jaha to Tondc, Clarke sees Finn standing in the woods off the side of the road. Bellamy asks if she is doing all right and tells her she did the right thing. Bellamy then tells her they are wasting time and what they really need is an inside man in Mount Weather. Clarke tells him she does not want him to go because she cannot lose him, too. While camping for the night, Clarke places her bedroll on the side of the Grounders. Bellamy tells her it is safer on their side but Clarke says they need to trust the Grounders. Bellamy places his stuff down on the Grounder side as well. After Clarke has fallen asleep, she is startled awake by the feel of Finn's of eyes watching her. She starts to turn around but doesn't. When they arrive at Tondc, everyone has to disarm before entering. Raven stubbornly forces Gustus to search her and disarm her. As they enter the village, Grounders shout at the Sky People, calling them murderers. One man stands in their way because he lost both his wife and child. Gustus fights the man and is about to kill him when Clarke begs Lexa to stop him so the Sky People will not get blamed. Lexa calls it off and announces to everyone that if anyone tries to stop the alliance, they will pay with their life.
During the funeral, Lexa gives an eulogy for the dead. She then passes the torch to Clarke who steps up and as she lights the pyre guided by Finn's hand, she says, Yu gonplei ste odon ("Your fight is over"), much to Indra's and Nyko's surprise. Lexa and Clarke then stand over the ashes of the funeral pyre as Lexa tells Clarke about Costia who was captured by the Ice Queen because she belonged to Lexa. They tortured her and cut off her head because they thought she might know Lexa's secrets. She got over the pain by recognizing that love is weakness. If Clarke does not do the same, then she puts the people she cares about in danger and the pain will never go away.
Later, at the alliance banquet, Kane brings forth some liquor to share. Clarke and Lexa both take a goblet but Gustus stops Lexa and takes a sip first before giving it back to her. As they toast and are about to take a sip, Gustus falls over from having been poisoned. The Sky People are searched and they find the poison on Raven. She claims it is not hers and that Gustus put it there when he searched her. Lexa commands for all of the Sky People to be locked up. Clarke asks Raven if she really had tried to poison Lexa and Raven punches Clarke in the face. Clarke sees Finn standing behind Raven and begins talking to him. Abby tells Clarke she knows how she feels and Clarke does not like the comparison between Finn's death and her dad's death but she realizes they are the same. Kane goes over to talk to Clarke and tells her that they need to figure out who would want Lexa dead. They come to the conclusion that the poisoner had to be someone who was trying to break the alliance. Nyko and Indra return and take Raven away. Indra tells them that Lexa is merciful and only wants Raven to die. The rest of them are free and they should run. Raven is then tied up outside to a pole where Lexa and Indra begin the "Death by a 1000 Cuts." Clarke remains seated in the alliance hall and sees Finn appear. He points to the goblet on the ground, making Clarke realize the poison was not in the bottle; it was in the cup. She runs outside and asks Nyko for the bottle and drinks from it, showing it was not poisoned. Bellamy realizes that it was Gustus who poisoned the cup because he was trying to protect Lexa from the alliance. Lexa commands Gustus to be tied up in Raven's place. That night, Raven gets the radio signal from Mount Weather and hears Jasper's message. Clarke tells Bellamy he was right and that they need an inside man. She tells him she was being weak and it is worth the risk for him to go. Clarke sees Finn again and tells him, "love is weakness," and he turns and walks away. Abby approaches Clarke to gives her ashes from the fire to say goodbye and Clarke tells Abby that she already said goodbye.
In Survival of the Fittest, Clarke is back in Tondc, planning with Lexa and her leaders a way to get both of their people out of Mount Weather. Quint gets argumentative with Clarke before storming off saying he can't be in an alliance with the Sky People. Lexa tells Clarke that waiting for Bellamy to get into Mount Weather is a prayer, not a plan. Clarke excuses herself for some fresh air and Major Byrne follows after. Clarke is wandering around outside when she spots Quint tracking her. He starts to taunt her and shoots arrows at her as she runs. Clarke pauses while running from Quint and sees Byrne whose arm has been ripped off. Byrne tells Clarke to save herself. Clarke begins running through the woods before she is again attacked by Quint. Lexa comes up and tells Clarke she can kill Quint when they hear a loud roar. Lexa says it's "Pauna" and slices Quint's leg while telling Clarke to run. The Pauna attacks Quint while Clarke, Lexa, and her guard look for a place to hide.
They quickly realize their hiding place is actually the feeding ground of the Pauna (a giant mutant gorilla) when she leaps over and attacks their guard. Clarke shoots at the Pauna but the bullets don't stop her and she chases after Clarke and Lexa, causing Lexa to injure herself. The Pauna grabs hold of Lexa but Clarke refuses to leave Lexa behind, saving her life even as they trap themselves into a room. Lexa tells Clarke that she is being weak by helping her escape the Pauna. Clarke tells Lexa that she needs her because she is smart. The Pauna finds them and begins beating against the door. Clarke has Lexa stand on one side of the door while they let the Pauna charge in and then race out the door, shutting it behind them and trapping the Pauna in the room. Later, Clarke awakens next to a campfire to find Lexa watching over her in the woods. The Pauna is still trapped and they are safe as long as the cage holds. This gives Clarke the idea of using all the caged Grounders trapped in Mount Weather as an army as long as Bellamy can get inside and release them.
In Coup de Grâce, in the woods, two Mountain Men are hidden from sight as they watch Clarke riding with Abby and several Grounders on their way from Tondc back to Camp Jaha. One of them has his sniper rifle trained on Clarke just as the group stops. Abby tries to get Clarke to drink some puddle water but Clarke refuses, telling her she needs to get back to the radio to see if Bellamy has contacted them yet. As they are mounting up, Carl Emerson, one of the Mountain Men, tells the other one he has a shot. Just then, the sniper is hit by an arrow and the bullet misses Clarke, hitting a Grounder behind her instead. Indra and Octavia have found the Mountain Men and Octavia fights Emerson, tearing his radiation suit. Indra tells her to "finish it" just as Clarke rides up and stops her, telling Octavia they want to keep him alive and to check for a patch kit for his suit. Octavia digs through Emerson's bag and finds a picture of Clarke and Lexa on horseback, the intended targets. Indra sends a rider to go warn Lexa of the attempted assassination.
Back at Camp Jaha, Abby is trying to help the Grounder who was shot by the Mountain Men. Jackson is helping Clarke with Emerson when Raven says she can hook up scrubbers to the airlock to make it safe to take off Emerson's protective outerwear. The Grounder ends up dying and Indra tells him, Yu gonplei ste odon ("Your fight is over") as she cuts a braid out of his hair. Clarke tells Abby to let her know when Emerson wakes up. After Emerson wakes up, Kane begins interrogating him but all Emerson will reply back is with his name and rank. Kane threatens to open the door to get Emerson to talk. Clarke tells Kane that torture doesn't work. Kane storms off and Abby puts Emerson under 24-hour guard.
Clarke joins Raven at the radio to see if Bellamy has checked in yet. Octavia enters and asks if there is any word from Bellamy and that Lincoln is still missing, too. Clarke tells her and Raven that Bellamy will get in. A PA announcement requests Clarke's presence at the airlock so Clarke leaves to deal with Emerson. Abby is waiting for Clarke and Kane and tells them that Jackson found genetic anomalies in Emerson's blood that could have only come from a Sky Person. Clarke wants to kill him but Abby tells Clarke she is not in charge. Clarke leaves and tells Raven that Mount Weather has already started bleeding the Delinquents and that it is over. Raven tells Clarke she is not allowed to give up and it is her job to come up with something. Just then, Bellamy's voice rings through on the radio, asking if anyone can hear him. Clarke picks up the radio and Bellamy tells her that the Delinquents have been locked up and that things are going to get ugly. He tells her that they need a plan that doesn't kill everyone because there are kids in there. Clarke tells Bellamy that he needs to turn off the Acid Fog and free the imprisoned Grounders. Bellamy asks Clarke to buy him some time so they won't discover him inside the mountain just yet.
Clarke brings Octavia, Indra, and several other Grounders with her to Emerson's airlock where Clarke makes the guard stand down and tells Emerson to get dressed. They take him outside and bring him to the gates where Kane and Abby try to stop her. Abby tells the Ark Guards to get the prisoner back inside but the Grounders behind Clarke step up threateningly. Clarke tells Abby, "you may be the Chancellor, but I'm in charge," and refuses to back down. Kane tells Abby that it's time they started trusting Clarke. Abby finally gives the order to stand down to the Ark Guards and Clarke makes her way through with Emerson. She tells Emerson to deliver a message to Mount Weather and that they have a secret Grounder army that the Acid Fog cannot hurt. With the tone generator they got off of Emerson, the Reapers can't hurt them either. Mount Weather has one last chance to let the Delinquents go and the Sky People will let them live. Clarke then releases air from Emerson's oxygen tank and tells him he has to make the eight-hour walk back to Mount Weather in six hours. Octavia asks how this will help Bellamy and Clarke tells her that it will make them look outside for this secret army instead of inside where they might find Bellamy and that Bellamy is the key to everything.
In Rubicon, at Camp Jaha, Clarke asks Raven if Bellamy has checked in yet. She is worried because he is late. Clarke sees that Raven has been working on plans for the dam and asks her how many tone generators have been created to stave off the Reapers. She gets upset when Raven tells her they only have two so far. Bellamy comes in over the radio and Clarke scolds him for being late. Bellamy tells Clarke about how the Delinquents are being taken away one at a time. Clarke tells Bellamy to find the missing Delinquents and leaves to tell Kane that she is no longer going to Tondc so he needs to go instead. Abby enters and Kane says that maybe the Chancellor should go to Tondc instead but Clarke says Abby is needed at Camp Jaha.
In Mount Weather, Bellamy is crawling through the air vents trying to find the missing Delinquents. He hears the sound of drilling and heads down a duct toward the noise and witnesses Dr. Tsing drilling into the now-dead Delinquent she had chosen earlier and extracting bone marrow to give to Emerson. Cage Wallace asks Emerson about Clarke and Emerson gives him the message that they're supposed to release the Delinquents. Cage then tells Emerson that it doesn't matter because tonight, he's going to drop a missile on Tondc where all of their leaders are meeting. Bellamy asks Clarke if she heard everything through his earpiece and she tells Raven she is leaving for Tondc. Bellamy asks after Octavia and Clarke lies that she is not in Tondc any more. Raven gives Clarke a hug goodbye.
Clarke rides into Tondc and is greeted by Octavia. She tells Octavia to take her to Lexa and Octavia asks what is wrong. In the woods outside Tondc, a Mountain Man (Whitman) reports back to Mount Weather that Clarke has arrived. Clarke and Lexa go someplace private and Clarke tells Lexa about the missile headed for Tondc. Lexa tells Clarke that they can't tell anyone about the missile because then Mount Weather will know they were warned ahead of time. Clarke wants to warn everyone but Lexa tells her that if she really did, then she would have done so before telling Lexa about the missile. Lexa and Clarke then leave. As they are sneaking out of Tondc, Clarke hesitates and tells Lexa they should find the spotter. She suddenly sees her mom in Tondc and goes back for her. Clarke gets Abby to leave with her while Kane and Indra realize Clarke and Lexa have gone missing. The missile lands on Tondc causing a massive explosion that knocks Clarke and Abby off their feet. Clarke's ears are ringing as she checks on her mom, telling her they have to go. Abby realizes that Clarke knew about the missile ahead of time and can't believe that Clarke would let it happen. She begs Clarke to tell her it was Lexa and it wasn't Clarke who did it, telling her she crossed a line but her secret is safe. Abby leaves in disgust and sadness and heads back into Tondc.
In Resurrection, Clarke witnesses the aftermath of the bombing in Tondc. A horse races past her, its mane and tail on fire. A woman stumbles out, holding her own amputated arm. Lexa grabs Clarke and shakes her to attention, telling her, "victory stands on the back of sacrifice." Clarke states that she wants all of the Mountain Men dead. Clarke tells Lexa that the spotter is the one who is shooting at the survivors and that she's going to find him and kill him. They begin hiking around Tondc as they look for the sniper, Whitman. Lexa keeps trying to convince Clarke that she did the right thing. They hear a noise ahead of them and run into Lincoln who is also going after the sniper.
Lincoln is shocked to see both Clarke and Lexa are safe and not in Tondc. He goes with them as they search for the sniper. They start looking for Whitman on higher ground but he spots them first and fires at them. Clarke draws his fire while Lincoln sneaks up on him and attacks Whitman. The sniper uses a tone generator to incapacitate him and holds Lincoln hostage with a knife while pointing a gun at Clarke. Lincoln tells Clarke to let Whitman kill him and then shoot Whitman because her people need her. Clarke replies, "You are my people," and kills the sniper in one shot through Lincoln's shoulder.
Lincoln returns with Clarke and Lexa and reunites with Octavia. Lexa starts to give a speech about making the Mountain fall and avenging the dead when Abby interrupts and tells them there are still others who need saving and to get back to work. Clarke walks up to Octavia and Octavia tells her she's glad she's not dead to which Clarke replies, "you, too." Clarke then tells Abby she needs to go back to Camp Jaha with the wounded but Clarke will be marching on Mount Weather because the sniper wasn't wearing a hazmat suit which means they're killing the Delinquents. Abby asks her to not forget that they are the good guys. Clarke and Lexa then leave for Mount Weather with Octavia, Lincoln, Indra, and the rest of their army.
In Bodyguard of Lies, in the Grounder camp outside Mount Weather, Clarke is stressing over the battle plans and Lexa tells her she should rest because she is wasting her energy. Clarke worries over whether or not Bellamy will be successful and Lexa tells her that's what it means to be a leader. Lexa tells her she was born to be a leader, just like her. Later outside, Clarke approaches Octavia across from a campfire. Octavia confronts Clarke about the bombing of Tondc and asks Clarke to tell her she didn't know it was coming. Clarke tells her she did it to save Bellamy and Octavia tells her that Bellamy would have never agreed to it and would have found another way. Clarke tells Octavia she cannot tell anyone and Octavia says she knows; the alliance would break. They are then interrupted by Lexa and Ryder, one of her warriors. Ryder tells Octavia to go relieve the southernmost guard position. Octavia tells them Indra expects her to be on a scouting mission with Lincoln. Ryder tells her that Indra will join her there shortly and Octavia walks off. Clarke tells Lexa that Octavia won't say anything and Lexa says she can't be sure of that. After Clarke leaves, Lexa tells Ryder to kill Octavia.
Clarke spots Indra seated near a fire and asks her why she is not on watch with Octavia. Indra tells her she doesn't stand watch and Clarke then asks where Octavia is. Indra tells her that she is with Lincoln, scouting as planned. Clarke then heads off to find Octavia and spots Ryder with an arrow aimed at Octavia. Clarke points her gun at his head and tells him to stand down and come with her and she leads him away from Octavia. Clarke brings Ryder back to Lexa and tells her that Octavia is not a problem. Lexa tells Ryder to stand down and sends him away. Clarke tells Lexa she can't kill anyone she doesn't trust. Lexa says yes, she can. She calls Octavia a threat and Clarke tells her that Octavia wouldn't ever endanger her brother's life. She then tells Lexa that she's a liar and really does have feelings, about Gustus, about Costia, and about the people who burned in Tondc. Lexa tells Clarke that she didn't let her burn. Clarke asks for Lexa to trust her that Octavia is not a threat and then warns Lexa that if she does anything to Octavia, Clarke will tell everyone about the missile.
Later, Lexa summons Clarke to her tent to tell her that Octavia has nothing to fear from Lexa because Lexa trusts Clarke. Lexa tells her that their ways may be harsh but it is how they survive. Clarke asks if maybe they deserve more out of life than just surviving and Lexa kisses Clarke. Clarke returns the kiss before breaking away, telling Lexa that she is not ready to be with anyone. The Grounders then raise the alert that a flare has been spotted and they prepare for battle. Lexa tells them to sound the horn and announces they are going to war.
As the Grounder Army marches on Mount Weather, Octavia is with Indra and the other Grounders when Clarke walks up and tries to assign Octavia to the Rear Guard where she'll be safe. Octavia tells her she does not take orders from Clarke; she takes them from Indra. She then breaks off their friendship. Indra tells Clarke Lexa is looking for her and Clarke takes off. Indra and Octavia then discuss the Tondc bombing and Indra tells Octavia that Lexa and Clarke didn't do anything; it was the Mountain Men. They then sound the battle cry as they continue their march.
In Blood Must Have Blood (Part 1), Clarke and Lexa are in their Command Post tent with their military leaders when Monroe and Sgt. Miller arrive and Sgt. Miller gives her a package of hydrazine from Raven. Abby is not there because she stayed behind to help the wounded from the bombing in Tondc. Lexa and Clarke then begin to discuss the action plan and Clarke makes it clear that it is supposed to be a rescue mission and that they do not want to wipe out the Mountain Men. Clarke explains how there are four teams: one at the dam (Raven and Wick), one in the mines (Indra and Octavia), one inside the mountain (Bellamy and the caged Grounders), and Clarke's team who will take the front door. Clarke has found out from Maya Vie that the main door has a flaw if the power goes out. Raven and Wick will take out the power coming from the dam, causing a one-minute delay before the backup generator kicks in. This gives them one minute to blow the lock on the door. The reason they don't also want to blow the backup generator is because it would leave the Mountain Men without power for too long, killing them all. Clarke then admits that they've lost contact with Bellamy after he blew up the Acid Fog machine. She goes on to tell them that once they get the door open, they will be under heavy fire from Mount Weather and that's what they want. While they're distracting the Mount Weather Guards, Indra and Octavia will be getting the Grounders and Delinquents out the back door and through the Reaper tunnels. Lexa then gives an encouraging speech, ending in the chant of Jus drein, jus daun ("Blood must have blood") and all of the Grounders chant after her.
At Mount Weather's front door, Monroe drills a hole into it so Sgt. Miller can insert the hydrazine bomb to blow the lock. Lincoln follows him to provide protection in case any of the Mountain Men try taking any shots. Sgt. Miller's hands start to shake as he tries to insert the bomb and Lincoln tells him to do it for his son. Sgt. Miller replies that the Mountain has taken enough from both of them and steadily inserts the bomb. Clarke and Lexa then wait for the power to go out. Lexa invites Clarke to their Capitol, Polis, telling her it will make her change the way she thinks about the Grounders. Clarke tells Lexa that she already has. They soon hear gunfire coming from the dam and get ready to blow the door.
In Mount Weather, the power goes out all over the place and Cage Wallace tells Emerson over radio to start the clock for one minute. Emerson tells Cage he's not letting them get near the door. When the light over the door goes off, Sgt. Miller tells Clarke they have one minute to blow the lock. Clarke and Lexa hold the trigger and press the button together but nothing happens. Clarke realizes that Mount Weather is jamming the trigger signal and says she has to get closer. As she starts to approach the door, gunfire rains down from above and Lincoln grabs her to safety. Emerson and his men shoot at them from the ridge above the door, preventing them from getting close to the door. A group of Grounders create a shield to take Sgt. Miller to the door so he can trigger it manually. They are all shot down before they can make it. They only have a few seconds left when Lincoln comes up with the idea to use a flaming arrow to trigger the bomb on the door. He makes the shot with only a second to spare and the lock is blown. Lexa tells Lincoln to remain with Clarke while she takes a group up the ridge to take down Emerson's contingent so they can work on getting the door open. After the shooting has stopped. Monroe notices that Sgt. Miller is still alive underneath the Grounder shields and helps him. Lincoln then commands the other Grounders to start hooking lines onto the door so they can pull it open. As the door creaks open, Clarke gives the command to attack just as Lexa interrupts, telling them all to stand down.
Lexa arrives from the ridge, towing Emerson along just as through the open door, harvested Grounders start stumbling out. Clarke asks if that means they surrendered and Emerson says, "not quite." Clarke asks Lexa what she did and Lexa tells her she saved her people but Clarke's people were not part of the deal. Emerson then heads back inside Mount Weather as Echo and the last of the Grounders are released. Lincoln asks Clarke what is going on and Clarke tells him what Lexa did. Lexa tells Lincoln the deal is done and orders the retreat to be sounded. Lincoln refuses to retreat and Lexa has him restrained. She then turns to Clarke and says, "may we meet again," before leaving with her army. Sgt. Miller, Monroe, and the rest of the Sky People tell Clarke it's time to go back to Camp Jaha to get reinforcements but Clarke refuses to leave, saying, "it can't be over," as she stands alone in front of the main door.
In Blood Must Have Blood (Part 2), down in the mines underneath Mount Weather, Octavia is waiting by herself for Bellamy to open the intake door. An alarm sounds and a body is dropped down a chute into a mining cart. Octavia sees Fox, dead from bone marrow drilling. Clarke comes running up, telling Octavia that Lexa and the Grounder army has left. Octavia and Clarke then get in a fight because Clarke is desperate to get into Mount Weather and will bring unwanted attention on them. Suddenly, the door opens and Bellamy appears with Monty, Jasper, and Maya and everybody hugs. Clarke asks Bellamy if he has a plan and he tells her no, but they can speak to Dante Wallace. Maya's oxygen tank beeps, warning her she is running low on oxygen. They split up with Bellamy, Clarke, and Monty going after Dante and Octavia going with Jasper and Maya to get her to Level 5 before she runs out of oxygen. In Dante's room in Mount Weather Quarantine, Clarke, Bellamy, and Monty come to him for help. Dante tells them that there is no one in the Command Center watching because everyone is trapped on Level 5. Clarke explains how they did everything they could to keep the Mountain Men safe and he needs to help them. Dante refuses to help but they take him with them anyway to the Command Center. Monty breaks them into the Command Center as Dante tells Clarke that he is not with his people because it is his responsibility to "bear it so they don't have to." Bellamy realizes that it was Dante who set up the alliance with Lexa.
Once in the Command Center, Bellamy sees Raven strapped to the table in the dorm room while Clarke spots Emerson in the Mess Hall. She calls him over the radio and tells him to give the radio to Cage Wallace. Clarke tells Cage she has his father and tells him she'll kill Dante if he doesn't let her people go. Dante tells Cage to "stay the course" and Clarke raises up her gun and aims it at Dante. Cage tells his dad he will take care of their people and Clarke shoots Dante dead. Clarke then tells Cage she will not stop until her people are free and will irradiate Level 5 if he does not let them go. Cage orders Emerson to go to the Command Center and kill them. Bellamy asks Monty to deactivate Emerson's key card as they watch Cage head toward the dorm. Clarke tells Monty to get it set up so they can irradiate Level 5 if they have to. In the dorm, Cage orders Raven to be removed from the table and has Abby put on instead. Kane tells them no one has to die because the Sky People can donate it. Cage tells him that it will never happen and they cannot all survive as they begin drilling into Abby. Bellamy warns Clarke there is no going back if they do this. Bellamy then sees Octavia and Maya get discovered by the Mount Weather Guards just as Emerson arrives outside the Command Center. Octavia and Maya are soon chased into the Mess Hall and are quickly surrounded by Mount Weather guards. Monty finishes the settings to irradiate Level 5 as Emerson gets ready to blow the door to the Command Center. Jasper is walking over to kill Cage while Abby is unconscious on the table. Bellamy watches as Octavia and Maya get caught in the Mess Hall. Clarke reaches for the lever and Bellamy places his hand on top of hers, saying, "together," and they pull the lever. The Mount Weather residents begin to succumb to the radiation. Emerson realizes what they have done and takes off running. Clarke, Bellamy, and Monty then walk through the Mess Hall and past all of the deceased residents of Mount Weather. Jasper is cradling a dead Maya and asks them what they did. He asks Monty how he could have let this happen. Clarke is reunited with her mother in the dorm and tells her she tried to be the good guy. Abby tells her, "maybe there are no good guys."
The next day, the Sky People return to Camp Jaha. Bellamy watches at the gate as Monty gives Clarke a hug before entering Camp Jaha. Clarke tells Bellamy to have a drink for her and Bellamy realizes she is leaving. He tells her, "if you need forgiveness, I'll give you that. You're forgiven." She tells him, "I bear it so they don't have to," before hugging him and kissing him on the cheek in goodbye, telling him, "may we meet again." As Bellamy turns back to Camp Jaha, he replies, "may we meet again."
Clarke is a beautiful young woman with pale complexion, blue eyes, a round face, dimple chin, and blonde hair. Her hair is often pulled back in a half-up/half-down style throughout season one. Clarke is 5'4" (1.65 m) and has a medium to slim physique. Clarke is also shown to wear earrings. Generally, Clarke is covered in dirt and/or blood and she very rarely smiles.
She usually wears thermal long sleeve shirts with crotchet cuffs combined with a jacket, dark jeans, and boots. She is often shown in dark colors such as; black, gray, navy blue, dark green and tan.
While in Mount Weather Quarantine, Clarke was seen in stark white clothing, a tank top and capris. After being released from quarantine, she was seen in pastel colored clothing, a pale pink singlet, a light blue jacket and light blue capris.
In Season Three, Clarke has adapted a style very similar to the Grounders, including braided hair and war paint.
Clarke is headstrong, determined, dependable, and intelligent. As a natural born leader who is capable of inspiring all around her, Clarke will contemplate and ask questions before acting. However, she has been shown to make impulsive decisions. She is also fair, selfless, caring, and loyal to a fault. Even after his death, Clarke shows a high level of devotion and admiration towards her father. She is quick to call people out on their behavior. She has a natural maternal instinct, as shown when she comforts Charlotte and later protects her. While she certainly has a good head on her shoulders, she is quick to accuse, and has displayed poor judgment which resulted in Charlotte’s death.
Despite the harsh world she lives in, Clarke is fiercely determined to save everyone’s lives, even if they do not deserve to be saved; which is evident when she helps John Murphy, who once tried to kill her and is partially responsible for Charlotte’s death. Finn believes her desire to save everyone comes from the fact that she could not save her father. Clarke has a strong moral compass; even to the point of stopping Miller and other Delinquents from killing Anya, their enemy.
Unlike Bellamy Blake, her co-leader, Clarke is idealistic and sees no reason for torture, cruelty, or violence of any kind. She does not wish for violence or war and tries to avoid fighting. However, she will betray her beliefs to protect those she loves and cares for; which is seen when she gives Bellamy the go-ahead to torture Lincoln to save Finn. She also agrees with Bellamy on bringing guns into camp for protection, even if she does not like the thought.
Clarke tries to make the best decisions for the camp, which often leads to her undermining Bellamy’s authority and rule. Clarke has a surprisingly keen mind for warfare and strategy, a trait that takes Bellamy, Finn, and Raven completely by surprise.
Clarke is described as a natural born leader, especially by her mother; who mentions Clarke got her leadership qualities from her father. Clarke’s father once mentions she gets her stubbornness from her mother. She has often shown maturity and wisdom beyond her age. Though Clarke can be rather blunt and closed off, she does have a vulnerable side, which she only shows around those she loves and cares for. Like her mother, she is a healer and puts her skills to good use.
Clarke is also portrayed as artistic, one of her strengths which was seen as she drew along the walls of her cell.
Clarke is Abigail Griffin's daughter. Before Clarke is sent down to Earth in the Pilot, Abigail tells her to be safe and that she loves her. After, Abigail closely watches over Clarke's vitals. While on Earth, Clarke learns the truth about her mother's involvement in her father's death in Earth Kills. This causes a rift between Clarke and her mother. To punish her mother for her father's death, she takes her wristband off, letting Abigail believe her to be dead. When Raven Reyes makes contact with the Ark in Contents Under Pressure, Clarke confronts her mother and tells her she knows the truth. Abigail tries to apologizes explain his death was never supposed to happen. Clarke truly believes she will never be able to forgive her mother for turning in her father. When Clarke believes her mother to be dead in the Exodus ship crash, she is devastated.
When they are reunited in Many Happy Returns, Clarke is happy to see her but their relationship is strained. Clarke goes behind Abby's back to the point of usurping her authority on numerous occasions. Abby often disagrees with the decisions Clarke makes in regards to the people. Tensions escalate in Coup de Grâce when Clarke tells her mother that even though Abby is the Chancellor, Clarke is the one in charge. In Resurrection, when Abby finds out that Clarke knew ahead of time about the bombing of Tondc, she is appalled that her daughter would do such a thing and begs her to not forget they are the good guys. By Blood Must Have Blood (Part 2), Abby has come to realize the difficult choices her daughter has had to make are not so different than the choices she made on The Council and tells her daughter that maybe there are no good guys.
The relationship between Clarke Griffin and Bellamy Blake starts out antagonistic towards each other. In the beginning, Bellamy shows a great amount of animosity towards Clarke and considers her to be "privileged". Bellamy looked down on Clarke because of her upbringing on the Ark. Meanwhile, Clarke often disagrees with the decisions Bellamy makes.
As season one goes on, however, their relationship develops into a partnership. Their partnership grows into a friendship filled with mutual respect and trust. They are both shown to care if the other lives or dies.
Bellamy and Clarke have been known to clash on many different occasions. This often leads them to be on the opposite sides of an argument. The two have also been known to contradict one another. One such occasion is when Bellamy makes a speech about staying at camp and fighting the Grounders. Minutes later, Clarke makes a contradicting speech about surviving to fight another day and that they should leave camp.
Clarke shows great concern for Bellamy during the fight with the Grounders. She refuses to close the door until Bellamy is back. When Clarke is forced to leave both Bellamy and Finn Collins outside to die, she is shown to be remorseful as she closes the Dropship door.
Clarke and Finn Collins start off as friends. They eventually become romantically involved. Although Finn is in love with her, Clarke has refused to be romantically linked to Finn.
Finn accompanies Clarke on the journey to Mount Weather. While on the trip Finn learns that the Ark is dying and tells Clarke they need to warn the people. Later the two bond in the bio-luminescent forest.
When Clarke searches for evidence of Jasper's whereabouts, Finn does not accompany her, at first. When he calls it a suicide mission, Clarke calls him a joke and leaves. Later he appears and joins the rescue party.
Clarke, Finn, and Wells look for medicine that can assist Jasper and eventually they are forced to take cover in a buried vehicle when an acidic fog appears. Clarke and Finn bond and talk about having fun. Later on, Finn explains to Clarke that Wells loves her and that she should forgive him. Finn is also quick to realize that it might not have been Wells who turned in Clarke's father. He asks Clarke this, leading her to realize that it wasn't Wells.
When things go wrong in camp, Clarke and Finn keep Charlotte protected after John Murphy seeks revenge for being accused of a crime he didn't commit. Finn leads the two to an underground bunker that he had found. That same night, Finn learns that all of the wristbands have been fried and loses hope that they will not contact the Ark. As a result he runs off to the underground bunker. Clarke follows after him and tries to calm him down. The two end up having sex.
Later that night, Clarke and Finn sit under the stars and see a falling pod, believing it to be a shooting star. Clarke is devastated after Raven Reyes, appears and is revealed to be Finn's girlfriend from the Ark.
Throughout the rest of Season One, Clarke tries to distance herself from Finn for Raven. However, they still have romantic feelings for each other. Finn holds Clarke's hand on the bridge before the peace meeting takes place. Finn also catches Clarke when she falls, due to her sickness, with knowledge that he may catch the virus Clarke has. Sometime after Raven and Finn break up, Finn confesses his love for Clarke, however, she rejects him because he broke her heart. In the final battle with the Grounders, Clarke is shown to very upset and regretful when she leaves Finn outside the Dropship to die.
When Clarke and Finn are reunited later in Season Two, Clarke discovers that Finn has massacred an entire village of Grounders trying to find her, and she backs away in horror once she sees what happened. Clarke tells Finn that he is savable, although, he has trouble believing it. Finn later shows remorse for his actions and when the Grounders want to kill Finn, Clarke defends him by trying to hide him at the Dropship to keep him safe. When Clarke says that Finn can't run off because the Grounders will find him and kill him, Finn says he deserves that for what he did. He then confesses his love for Clarke again and she begs him to stay. Later on, after they are both attacked and almost killed by a Grounder, Clarke assures Finn that the things they have done to survive do not define who they are, but Finn believes that this is who they are now. Finn later gives himself up to the Grounders at the Dropship to save his people from being slaughtered by the Grounders. Later that night, Clarke tries to convince Lexa to show mercy to Finn and let him go, but Lexa won't do it. Clarke also tries to get Lexa to kill her in place of Finn, but she won't let Clarke take his place. Clarke asks permission to say goodbye and Lexa accepts. Clarke runs to Finn and kisses him and tells him that she loves him. Finn says that he is scared but Clarke reassures him that he will be okay. He whispers "Thanks, Princess" in Clarke's ear and his head drops to her shoulder. Once Clarke pulls away, the knife Raven gave to her to kill Lexa is covered in blood, and Clarke's hand is covered in blood. Clarke had killed Finn, and he told her "Thanks, Princess" to thank her for killing him quickly, stopping the torturous death the Grounders wanted to give him.
Clarke and Wells Jaha were best friends. They were best friends prior to being sent to Earth. It is shown that their families were close.
One day, Clarke told Wells that her father discovered that the Ark is dying. He promised he would not tell anybody. Later that night, Clarke's father was floated and she developed a hatred for Wells, believing him to have told his father.
Before Wells' death, the truth about Clarke's father's death is revealed. Clarke and Wells never got the chance to fix their friendship, as he was murdered the next morning.
"You get your stubbornness from your mother. That's what I love about both of you."
Clarke is Jake Griffin's daughter. They were very close while he was alive. Even after his death, Clarke speaks highly of her father and shows great devotion to him. Jake's death left her devastated and emotionally scarred. As a memento Clarke continued to wear her father's watch.
Clarke overhears a conversation between her mother and her father and learns the Ark is failing. Clarke learns her father plans to tell the citizens of the Ark. Clarke offered to help with her father's plan but he refused her because he didn't want to involve her. When Jake was arrested and later floated Clarke blamed herself for his death. She believed she killed him by telling Wells Jaha of Jake's plans.
Clarke later learns, however, that his death was not her or Wells' fault. Clarke refuses to forgive her mother for the part she played in Jake's death.
Clarke: "I feel the sun on my face. I see trees all around me, the scent of wildflowers on a breeze. It’s so beautiful. In this moment, I’m not stranded in space. It’s been 97 years since a nuclear apocalypse killed everyone on Earth, leaving the planet simmering in radiation. Fortunately, there were survivors. 12 nations had operational space stations at the time of the bombs. There is now only the Ark, one station forged from the many. We’re told the Earth needs another 100 years to become survivable again. Four more space-locked generations, and man can go home, back to the ground. The ground, that’s the dream. This is reality."
Clarke(To the 100): "Do you think we care who's in charge? We need to get to Mount Weather. not because the Chancellor said so, but because the longer we wait, the hungrier we'll get and the harder this'll be. How long do you think we'll last without those supplies? We're looking at a 20-mile trek, okay? So if we want to get there before dark, we need to leave now."
Clarke: "You idiots. Life support on the Ark is failing. That's why they brought us down here. They need to know the ground is survivable again, and we need their help against whoever is out there. If you take off your wristbands, you're not just killing them. You're killing us!"
Clarke(To Charlotte): "See that bright star up there? That's the Ark orbiting above us. I think whatever happened up there, you know, the pain maybe we can move past that now. Maybe being on the ground is our second chance."
Clarke(To Wells): ""I made a mistake, Clarke." Not good enough. You know, I bet you couldn't wait to run to daddy. Tell him everything so that he'd finally believe you were the perfect son he always wanted."
Clarke(To Wells): "Wells? I know I probably don't deserve it, but I need to know the truth. It was my mom. Wasn't it? She's the one who told your dad. I didn't want to believe it. I-I couldn't. I blamed you because my father's dead and it's my mother's fault. Isn't it? Wells Please."
Clarke(To Bellamy): "No, I was wrong before, okay? You were right. Sometimes it's dangerous to tell people the truth. But if we're gonna survive down here, we can't just live by "whatever the hell we want". We need rules."
Clarke(To Bellamy): "Bellamy, don't you see what this means? You're not a murderer. You always did what you had to do to protect your sister. That's who you are. And you can do it again, by protecting 300 of your people. Where's the radio?"
Clarke(To Raven): "Do you think I wanted this? I didn't even know you existed. Look, as far as he knew, you were dead, Raven. Or you would have been soon enough. My mom, too, and everyone we ever knew on the Ark, and there was nothing we could do to stop it."
Clarke(To Thelonious): "I know you both think that betraying my dad, killing him, was an unavoidable tragedy, but I don't see it that way, and I never will. So just tell me who's next and let someone who actually wants to talk to their parents have a turn."
Clarke(To Thelonious about Bellamy): "Before you do, I'd like to say something. When you sent us down here, you sent us to die, but miraculously, most of us are still alive. In large part, that is because of him, because of Bellamy. He's one of us, and he deserves to be pardoned of his crimes just like the rest of us."
Clarke(To the 100): "If we leave, we may never find a place as safe as this. And God knows, in this world, we could be faced with something worse tomorrow. But that doesn’t change the simple fact that if we stay here, we will die, tonight. So pack your things, just take what you can carry. Now!"
Clarke(to Carl Emerson): "I have a message for your leader. We’re coming for him. You’re watching us, but you haven’t seen a thing. The Grounder army is bigger than you think, and even if you could find it, your acid fog can’t hurt them, and now, thanks to you… Neither can the Reapers. So you have one last chance. Let our people go, and we’ll let you live. It’s just that simple."
