I have to think of everyone. I know you don't want to hear this, but you have to sacrifice the few to save the many. Like I said, good can come out of even the darkest acts.
— Jaha to Murphy. [src]


Thelonious Jaha is a major character in the first, second, third, and fourth seasons. He is portrayed by starring cast member Isaiah Washington and debuts in the series premiere.

Jaha was the last Chancellor of the Council that governed the Ark. As the Chancellor, Jaha had a major role on the Ark, that brought on many hard decisions and challenges, such as ending the lives of hundreds of people in order to save thousands, or choosing to stay behind on the Ark to ensure that some of humanity can return to their home planet.

At the end of the first season, Jaha was alone on the Ark in communication with survivors of the Ark's descent to Earth. In Season Two, Jaha was able to escape the Ark via an inactive nuclear missile. He ended up crash landing on Earth and survived the impact. He was captured by the Grounders and later returned to the Sky People with a message from the Commander to leave or die. Jaha took the threat seriously even though the new Chancellor on Earth, Abigail Griffin, refused to leave. He gathered a group of followers and leads them into The Dead Zone, in search of the City of Light. The group soon dwindles down until only Jaha and Murphy remain when they make it to an island where Jaha is introduced to A.L.I.E..

Sometime after travelling to the mansion, Jaha works with A.L.I.E. to create a device that allowed her to leave. Jaha takes the "key" to the City of Light, falling under A.L.I.E.'s complete control. The two travel to Arkadia and begin to create a small following of people, eventually leading to the mostly all the residents of Arkadia and Polis joining A.L.I.E.. However, a small resistance once led by Marcus Kane fights back against A.L.I.E. and eventually she is defeated after Clarke Griffin enters the City of Light and pulls A.L.I.E's killswitch. Jaha and every other chipped individual are freed.

In the fourth season, Jaha returns to Arkadia and assists with repairing Alpha Station in preparing for the looming death wave. While researching solutions, Jaha comes across a cult called the "Second Dawn", who created two bunkers to try and survive the apocalypse. He finds the location of one with Clarke and Bellamy, but it is not properly sealed. With the help of the new Flamekeeper, Jaha finds and opens the second bunker which is located under Polis.

Early life Edit

Thelonious Jaha was born on the Ark. He was the third generation of Arkers to live in space, a transitional generation, of the last surviving members of the human race. He had a son, Wells, and was friends with Jake Griffin and his family, with Clarke and Wells becoming best friends. Before becoming Chancellor of the Ark, Jaha was an engineer and supervised the redesign of sector 5. He was elected Chancellor some time before the problem with the Ark's life support system was discovered. The Council decided to keep on a "need to know" basis to avoid panic, however, when Jake attempted to go public, Abby warned Jaha hoping he would be able to convince Jake not to go through with it. Instead, Jaha and Kane had Jake floated and Clarke arrested and put into solitary confinement to ensure their silence of the problem.

In order to give the Ark time to fix the catastrophic air failure, Jaha and the Council came up with a plan to send the 100 imprisoned delinquents to Earth as well as to cull 209 people from the Ark. Just before the 100 delinquents were sent to Earth, Wells learned of the plan and set fire to the Eden Tree to get on the dropship. Before the dropship launched, Jaha was shot by an unknown assailant.

Throughout the Series Edit

In Pilot, Chancellor Jaha appears in a recorded message for the 100 delinquents that is played in the dropship on their way down to Earth. He explains their situation and their mission and offers hope and a second chance in case they happen to survive the experience.

On the Ark, it is discovered that Jaha had been shot prior to the Delinquents' dropship being launched. Abby rushes to save his life. While the Chancellor is in surgery Kane begins diplomatic procedures to become Chancellor in case Jaha does not survive. Abby is arrested by Kane for using more than the allotted medical supplies per patient. She is about to be executed for her crime but Jaha intervenes. When Abby leaves angrily with Callie Cartwig Jaha asks Kane about the Delinquents on Earth.

In Earth Skills, Jaha is introduced when he walks into the Earth Monitoring Station, still wearing his nightclothes/robes and clutching his stomach. He looks at the screens and sees that Wells' transmissions have stopped. He then realizes that they sent the delinquents down to Earth to die. Abby tries to convince him that it was the right thing, but Kane interrupts Abby and tells Jaha that the wristbands are telling the Ark that Earth is not survivable. Abby protests and tells Jaha that there is still hope.

Later, Abby is in Jaha's room, tending to his injury. He asks her why she came instead of an apprentice and she asks him about his opinion about whether or not they should cull 100 citizens. He says that it seems hopeless and the children die first. He then states that if he doesn't act, everyone will die. When Abby tells him that they have acted by sending 100 delinquents to earth, he corrects her and says that 76 kids are on Earth and that 24 kids are dead, including Wells. He tells Abby that she has no proof of Earth's survivability and that when the end of the human race is at stake, hope is not enough. Abby protests, then leaves quickly, as Kane enters Jaha's Chambers. Jaha asks who shot him. Kane tells him that it was a janitor named Bellamy Blake. Jaha then accuses Kane of taking a part in his assassination attempt. Kaha denies the accusations and calls Jaha weak then leaves

Next, we see Jaha in the council meeting. After hearing that Abby thinks that the kids are taking off their wristbands, Jaha protests, saying his son would never do that. When the vote in the council is a tie, Jaha is required to break the tie. He decides to abstain, meaning that 100 more people will have to be killed when he votes again in 10 days. He tells Abby that he needs proof by then.

In Earth Kills, Jaha is first seen watching an old soccer game with Wells, Clarke, and Jake Griffin. They jokingly banter with each other about the game until Abby walks in and tells Jake something. He leaves and Jaha asks if everything is okay. Later in the episode, Jake is arrested for trying to tell the people about the oxygen levels. Clarke assumes this is because Wells told Jaha.

Next, we see Jaha at Jake's execution. He has a pained expression as Abby and Jake embrace for the last time. When Wells and Clarke run in and are held back by the guards, he says they can come forward. The Griffin family hug until Jaha says that it's time and they separate. He nods to the executioner, and Jake is floated.

In Contents Under Pressure, Jaha is first seen at Abby's Hearing. He's given up on the fate of the 100 and is the one who strips Abby of her seat in the council. When Clarke and Raven connect with them on the radio, he asks Clarke about the fate of his son. She tells him that his son is dead. Later we see him in his room, mourning the death of his son. He begins to talk to the former chancellor, Diana Sydney. She mentions that he's started Project Exodus, a program to bring the Ark back to Earth. Later, Kane feeling the guilt of "killing" the section 17 volunteers, is faced by an angry mob, which Jaha saves him from. Jaha reassures him that the choice was not only his. Jaha then holds a meeting with the station representatives. He apologizes for keeping secrets and lets them know that Earth is survivable. When accused of keeping further secrets, he tells them that he is suffering too. Pressed further, he shouts about the loss of his son. The group quiets down, and he eventually appoints Diana Sydney as a new council member. At the end of the episode, he swears Sydney in and speaks about Project Exodus to the Council. At this time, he explains that there are a lack of dropships on the Ark for all the citizens. The episode ends on this cliffhanger.

In Day Trip, Jaha is introduced talking to Clarke on the video camera, set up between Earth and The Ark. He inquires about the grounder, then asks if they'll be able to survive winter. Jaha mentions that citizens from The Ark will be coming soon. He argues the importance of looking for supplies, then goes to talk with Clarke alone. He tries to convince Clarke to talk to her mother, but she refuses. Jaha is seen later, as a hallucination of Bellamy, blaming Bellamy for the deaths he's caused. Seeing this hallucinogen and fighting it gives Bellamy the strength to face the real Jaha, which he does later, via webcam. Jaha forgives Bellamy for shooting him, then discovers that Commander Shumway had been behind his assassination attempt.

In Unity Day, on Earth, Jaha's Unity Day speech is being broadcast. Jaha says that in under 60 hours, the first ship will be launched, carrying reinforcements for the 100. He tells the 100 to stay strong, and that help is on the way. Diana notes that he cut his speech short. After the bomb explodes, Jaha looks at one of the hurt children with a stunned expression, before expressing his sympathies towards Kane and the loss of his mother. Kane realizes the bomb was meant to kill him and notes that Diana Sydney is missing. Jaha announces that he is putting the Ark on lockdown and the dropship on hold. After the power begins to go out, Jaha is seen, talking to one of the electricians. Jaha says that he is lifting the lockdown in order to evacuate citizens before a complete power failure. Realizing that Kane is missing, he goes to find him and sees him freezing to death. Jaha realizes that Diana is taking the Exodus Ship for herself. When we return to the Ark Jaha is seen locked out of the ship and decides to try to keep the ship from opening. It doesn't work due to one of the workers betraying the Ark in order to go to the ground and Jaha is left on the other side, inside of the Ark that has now lost power.

Jaha was not featured in I Am Become Death, although it was mentioned that contact had been lost with the Ark.

In The Calm, Jaha is first seen after he lowered the temperature to protect the ark. It is seen that he is locked in a room that cannot be opened, along with several other people. Jaha commands that Kane leaves him to go protect any other citizens that are still alive. Kane refuses and opens the door to the room with the help of several other oxygen starved citizens. Jaha criticizes Kane for not following his orders, but Kane states that it was necessary. He wonders aloud what he should do now, concerning the Ark. Jaha then remains as a background character the rest of the episode.

In We Are Grounders (Part 1), Jaha is speaking to the remaining Ark citizens, telling them that they will be dead in less than 24 hours. After telling the Ark Citizens to go, he tells Kane, that he's welcome to try and find a solution, but he (Jaha) will be drinking scotch and waiting for his death.

We see Jaha later, watching a video of young Wells and Clarke. While watching, Clarke mentions the Thrusters, that keep the Ark in space. Jaha gets an idea and leaves. Near the end of the episode, Jaha walks in to see Kane and Sinclair replaying scenarios. Jaha questions using the Ark as a dropship to get to earth. They begin to plan out this idea as the episode fades.

AbbyJaha 1x13
In We Are Grounders (Part 2), the Ark makes plans to go down to earth. Jaha is on Alpha Station when he finds out the launch needs to be executed from inside the operations center. While Kane makes the decision to sacrifice himself, Jaha is first and he launches the Ark to the ground. When Mecha station lands, Jaha, and Abby talk to each other and Jaha tells her to go and find their people.

In The 48, Jaha is still on the Ark (or what's left of it) and is still in contact with the people on the ground. However the contact down creases, and Sinclair mentions to Kane that there hasn't been contact in the past hour. In the end of the episode, we see Jaha trying to contact the people on earth. He says it has been 12 hours since last contact. He says he can no longer help and that his job is done. He is tired and looks sleep deprived. He orders Sinclair to tell Kane and Abby that they are on their own. As long as they work together everything will be okay. He urges Sinclair to remind them to keep their people safe. Jaha then looks at the monitor with Wells' file on it, before he switches out the power. He then hears the echo of a baby crying on the Ark. Sinclair says there is still radio silence.

In Inclement Weather, Jaha makes his way through the Ark's corridors. He follows the sound of the cries, and eventually walks into a room. When there is no sound of the baby he listens again, and then finds the baby in the closet behind a jammed door. After that, he starts to anyway he can to get the child to the ground. When he sees the child holding a chess piece, he gets the idea to use a rocket with an airlock to go to the ground. However, he'll have to go outside to get to it.

Jaha constructs a carrier for the baby after using his chancellor authorization code to open the airlock. After gearing up in a spacesuit, he notices a crack in the helmet. He decides to put the helmet on and prepares for his task. He then gets flown out of the airlock, before heading for the missile. The helmet breaks, and barely makes it to the missile.

When he realizes shockingly that there is no baby, he freaks out, until he sees his son Wells holding the chess piece. Jaha then realizes he has oxygen deprivation, and says he's done. When Wells mentions that his people still need him, Jaha says he did his job by getting them to the ground. He says he misses his son, and Wells guides him to the tasks he needs to fulfill to successfully launching the missile. The missile ultimately lands him in an unknown desert on Earth and Jaha exits it, kneeling to the ground and feeling the sand between his fingers.


In Many Happy Returns, Jaha at first seen unconscious in a unknown desert. A young boy name Zoran, who saw him come from the sky stumbles upon him and observes him. Jaha quickly wakes up however after Zoran takes his chess piece. Zoran then takes him back to his home, where he lives with his mother and father. Sienna, his mother is first hesitant to let him stay but allows him shelter for the time being. As Jaha and Sienna continue speaking with each other, an unmasked Zoran walks in with a deformed face. This startles Jaha and makes Zoran run off. Sienna then explains in her village boys like Zoran would usually be killed, but she ran off with her family instead to protect her son. Later when Zoran walks back in the room, Jaha says he does not need to wear a mask in front of him. The two then bond and Jaha tells him about what the chess piece is, and even talks about Wells. As time goes on, however, Jaha is given away by Sienna for a bounty, however, Jaha ultimately respects her decision, and walks away with the man who attacks him with a baseball bat.

In Human Trials, he is seen briefly in an underground complex used as a jail by the grounders. There he stumbles upon Kane, which makes Jaha say "So we meet again".

In Fog of War, him and Kane are first seen shackled in an underground train station, used as a prison for the Grounders. Kane desperately tries to break free, but Jaha says that they were kept alive for a reason, and he should be patient. Soon, Gustus, Lexa, and few other Grounders arrive. Lexa is sent to watch over Kane and Jaha, and Gustus tells the two that they both have committed many crimes against their people and deserve punishment over it. Gustus drops a knife on the ground, telling them that if one of them does not kill the other, they both die. For hours they try to figure out a plan to escape, but they couldn't think of anything. Eventually, Kane picks up the knife, seemingly about to stab Jaha, but reveals that he wants Jaha to kill him for Jaha to escape. When Jaha refuses, Kane slits his arm, but Jaha and Lexa save him before he could do any more damage to himself. When Gustus returns, Jaha grabs Lexa and puts a knife to her throat. However, Lexa takes down Jaha and reveals that she is the Grounder Commander and only needed information from the two. As Jaha is beaten and thrown away, they keep Kane locked up in the cell. Jaha is then seen at the end of the episode arriving at the camp, telling Abby that the Grounders are coming to attack Camp Jaha, and they have two days to evacuate.

In Remember Me, Kane mentions Jaha when he tells Abby that she can't keep him locked up forever.

In Survival of the Fittest, he is seen talking to John Murphy while he is on mopping duty. He tells Murphy that he wishes to visit the grave of his son, and he is asking him as the graves are unmarked. Murphy seeing how it is more exciting than his current job goes with Thelonious to The Camp to visit Well's grave. Jaha mourns his son, and Jaha asks how close he was to Murphy. Murphy says that he was said to be the murderer of Wells, and says how Clarke likely lied about his son's death, and Wells was stabbed in the neck by a little girl. Jaha says that the choices he made helped his people get to the grounder, and it was for the best no matter what happened, but Murphy doesn't listen.

Later while they are in the dropship, Jaha tells Murphy that he remembers his father Alex Murphy and that he remembers everyone that he floated. Before Murphy can say anything, a dozen Sky People walk into the camp, and Jaha reveals they are on a mission to the City of Light. Jaha tells Murphy to join him. At first, Murphy is hesitant, but Murphy rides along with Jaha and the rest of the Sky People.

In Rubicon, Jaha is seen with Murphy and the rest of his people on their journey through The Dead Zone to reach the city. As they journey forward, they come across a grounder named Emori, who is trying to pull her supplies. At first, she is hostile, but Jaha tries to offer water to her. Caspian is hesitant to help her, but Jaha gives her the water anyway and she joins their group.

As they move forward a grounder with an RPG appears and Emori holds Murphy at knife point. Jaha says to surrender their supplies to them, and they listen. When Murphy wakes up Caspian and 5 others are ready to leave, but Jaha says to push forward, and so Jaha, Murphy, and the remaining group pushes forward to find the City of Light.

In Bodyguard of Lies, while Murphy is telling a Sky Person, Harris, to keep quiet, the man talking is exploded by a mine. One sky person, shocked by what has just happened backs away and is killed by a mine as well. Jaha then tells everyone to freeze as they are in a mine field. As they await a sandstorm to pass through, they slowly make haste through the mine field. Jaha then zigzags through the sand desert. One group member, Richards, eventually loses his patience and begins running, but is stopped by Jaha, centimeters away from the mine.

When they finally pass the minefield, Jaha, Murphy and 2 others climb a sand hill as they see the lights shining in the sky, believing it to be the city. However when they reach the top, they only come across hundreds of solar panels. Jaha in disbelief says there is more to it than what they have found, but the others aren't believing him. When Murphy throws a rock at a panel, a flying drone appears, overseeing Jaha and his people. The drone then flies off onto the ocean, where the group comes across a boat. Jaha says this is another sign, and they must push forward to find the city. The others are hesitant, but seeing no other option they ride on the boat to cross the ocean.

In Blood Must Have Blood (Part 2), Murphy, Jaha, and the others are seen rowing their boat. One the Sky People, Craig, complains about how they need rest, but Jaha says to move forward. Suddenly, a sea creature of some sort attacks the boat, taking one of the Sky People, Richards. As the creature circles the boat, Jaha throws Craig into the water to save himself and Murphy. Jaha and Murphy then horrifically watch as their friend gets swallowed by the creature. After the disaster, the two manage to make it to shore, where they find a lighthouse. Jaha sees the drone again, and leaves Murphy on the shore wounded telling him he will come back for him, chasing the drone.

When Jaha finally reaches the drone, he comes across a mansion with tons of drones circling it. He enters the mansion in search of answers, and is greeted by a woman named A.L.I.E., who welcomes Jaha into her home. Jaha asks how he knows his name, but before anything Jaha discovers that the woman is a hologram. The woman then takes Jaha into her room where he comes across the same missile that he used to arrive down on earth. A.L.I.E. then says that they have a lot of work to get done.

In Wanheda (Part 1), Jaha welcomes Murphy back in A.L.I.E.'s mansion, and claims that he has found the City of Light. Murphy greets him with anger due to the fact that Jaha allowed him to stay locked up in the bunker for three months. Murphy swings a punch at Jaha but misses because his body has been weakened from living in solitaire for three months. He falls but Jaha catches him and carries him away. Later, Murphy tries to speak to Jaha but A.L.I.E. appears and notes that Jaha is meditating in the "City of Light", and therefore can't hear him. When Jaha awakes, he attempts to tell Murphy how wonderful the City of Light is, and that it doesn't even compare to the real world. Murphy isn't having it, however, and reminds Jaha that A.L.I.E. was the one who ended the world. Jaha refutes by saying she saved the world. Murphy gets frustrated and leaves the room, but A.L.I.E. assures Jaha that "he'll come around". That night, Jaha finds Murphy on the shore where they first arrived three months ago. He apologies to Murphy for keeping him locked in the bunker, but tries to justify it by saying he needed time to convert the nuclear warhead into a power source so A.L.I.E. could become mobile. Jaha then offers the stone-like object he used while meditating to Murphy as a device that will allow him to experience the City of Light. He also explains to Murphy that in the City of Light, there is no hate, pain, or envy. Murphy declines and sarcastically replies that those are the ABC's of him. Jaha tells Murphy to decide later as he hands him the device. Once Jaha sees Murphy climb aboard a boat that Emori has pulled to shore, he asks Murphy if he changed his mind. Murphy says he might. A.L.I.E. appears again, telling Jaha that she told him Murphy would come around. Jaha leaves on the boat with A.L.I.E., Emori, Murphy, and Gideon.

In Wanheda (Part 2), Jaha and A.L.I.E. are wandering around the empty City of Light. A.L.I.E. reiterates how there will be no more suffering in the City of Light and Jaha volunteers to fill the place, starting with the Sky People. Murphy's voice breaks through Jaha's mind journey to the City of Light and he opens his eyes, seated at the front of the boat that has arrived on-shore. Emori tries to unload the case containing A.L.I.E. and Gideon grabs it from her, taking it with him off the boat. Emori tells them they're going around the Dead Zone this time as they start walking. Emori's brother, Otan, asks Jaha if he has really been to the City of Light. Jaha takes Otan off on a walk while Gideon sits and thinks his way into the City of Light.

Later, after Emori kills Gideon and she and Murphy take off back to the boat with A.L.I.E.'s backpack, Otan shows up and demands the case from Murphy, taking Emori hostage. Jaha arrives as Emori asks what is going on. Murphy says that Otan "ate the damned chip" that Jaha gave him and threatens to drop the case into the water unless they let Emori go. Jaha starts proselytizing about the City of Light to Murphy and Murphy goes to drop the case in the water. Jaha and Otan give up and release Emori. Murphy throws the case far from them and into the water, leaving them running after it while he and Emori take off in the boat. Jaha is transported to the City of Light and tells A.L.I.E. they should go after them. Otan is there with them and his face is no longer disfigured. A.L.I.E. tells Jaha there is also no death in the City of Light as Gideon appears, also not disfigured and not dead.

In Hakeldama, Jaha returns to Arkadia with ALIE and Otan with the goal of convincing people to join the City of Light. He and Otan arrive at the gate and are greeted by Shawn Gillmer. Gillmer, however, refuses to let Otan enter under the orders of Chancellor Pike he then asks Otan to hand over his backpack. Otan refuses and Gillmer shoots him and ends up killing him. In Otan's final moments, Jaha tells him to go the City of Light and says that ALIE will be waiting. He then notices a very concerned Abby looking at him.

Jaha later meets with both Kane and Abby informing them he has found the City of Light. Neither of them believe him but their conversation is interrupted by Hannah Green, who informs him that Chancellor Pike would like to the speak with him. Jaha then speaks with Pike and requests permission to distribute his chips which Pike grants to him, as long as he doesn't interfere with Pike's plans. Jaha is seen preaching a group of Arkadians about the City of Light and it's ability to relieve pain when Raven calls him out on it. He and ALIE agree they'll need Raven since if she joins others will follow and he tells her he'll be ready when she is.

Jaha then approaches Raven who is sorting scrap metal for ammunition and offers her the key to the City of Light once more, telling her she truly has nothing to lose.

In Bitter Harvest, Jaha is seen distributing chips to more Arkadians while a concerned Abby and intrigued Jasper watch. He later offers Jasper a chip which he almost accepts before Abby intervenes. Abby asks Jaha if he would've given a chip to Wells and Jaha seems confused at this. ALIE reminds Jaha that Wells is his son as Abby informs Jaha she is shutting him down. Jaha begs her not to saying that it has been so long since he thought of his son and that the City of Light will relieve pain. Abby takes his bag of chips and leaves after informing Jaha "whatever it is, it relieves more than just pain." Jaha seems somewhat distressed before ALIE reassures him. Jackson who is revealed to be chipped informs the two that he will keep an eye on Abby.

In Terms and Conditions, ALIE, Raven, and Jaha are still searching for the other AI. Raven tells Jaha that she and ALIE have run the calculations and determined the debris of Polaris must have landed in the ocean. When Jaha asks her what the percentage of accuracy is Raven tells him 70 to 80% which Jaha deems as not good enough. Raven tells Jaha she can't guarantee any more accuracy than that but Jaha offers her more resources. He says they will need to increase the population of the City of Light in order to make ALIE more powerful. Raven agrees but tells him the issue is that when Abby confiscated their chips Pike took the chip maker. Jaha tells her she'll need to get it back. At first, Raven is skeptical and asks who would even consider doing something so stupid. The two then notice Jasper yelling at Sinclair in the distance and are struck with an idea.

Later, Jaha is talking to ALIE. ALIE is perplexed as to why Raven was able to resist. Jaha informs her that free will is the problem and they must override it. ALIE says she can not but Jaha informs her he may be able to.

In Fallen, Jaha is speaking with ALIE about Raven who is trying to remove the chip from her head. ALIE reassures him it will not work. She later asks him about the wristbands he sent to ground with the 100 and says that Raven may have found a way to disconnect. Jaha commands the chipped victims to find the wristband. He finds Jasper in a storage room taking the wristband and with the help of some chipped victims, he is able to chain Jasper to a bar on the wall and smash the wristband with a hammer.

He is later seen standing with Raven and Jackson as Abby wakes up. He informs her she's stopped them for too long and she needs to take the chip and tell the people of Arkadia that what he is doing is safe. Abby at first refuses but when Raven slits her wrists in order to give Abby a choice. Abby begs Jaha to untie her so she can save Raven but he refuses and says she can be freed when she takes the chip. Jaha gives Abby the chip then unties her wrists when he knows she has swallowed it.

He is later seen standing with Abby as they distribute the chips to the people of Arkadia. ALIE alerts him that Jasper is taking Raven and he commands the chipped victims to pursue Jasper. As Jasper is escaping in the rover Jaha has the chipped victims shoot at him. As Jasper gets away ALIE reassures him that once Raven wakes and sees her surroundings, ALIE will locate her and the rest of her friends.

In Nevermore, he and ALIE stand in the City of Light. He reassures ALIE they will get Raven back but she informs him the situation has escalated. She tells him that with Raven's knowledge she'll understand that the second A.I can stop ALIE and they'll need to kill them all.

In Demons, Jaha arrives in Polis disguised as a grounder. He informs her he knows she isn't the real commander and when she asks how, he says that Murphy told him. Jaha informs her that the people will soon discover she is ruling with the wisdom of the Commander's spirit and he offers her the key to the City of Light. Ontari orders Murphy be locked up and takes the key.

In Join or Die, Jaha and the chipped victims have completely taken over Polis. He orders that Pike be freed before offering him the chip. When Pike refuses to take the chip, Jaha has him locked away. He offers the same thing to Kane. When Kane refuses as well, Jaha jas the guards take him. However, Abby approaches Jaha and tells him to leave Kane to her.

He later watches as Kane is nailed to a cross after refusing to give Abby information regarding Clarke. Later, Jaha informs Kane he is running out of time and he needs an answer. Kane tells Jaha to just shoot him and get it over with. Jaha, however, decides against this, saying that if he shoots Kane he won't the information he's looking for. He then turns the gun on Abby's head instead. This causes Kane to surrender and Jaha hands him the chip in delight.

In the flashbacks, Jaha, Kane, and Abby meet with Pike and inform him he will be teaching Earth Skills to the Delinquents. After Wells arrest, Pike offers Jaha his condolences and tells Jaha he's taught the Delinquents nothing. Jaha informs him that he is the kid's last hope and he needs to find a way to teach them.

In Red Sky at Morning, Jaha is standing with ALIE in the City of Light when ALIE notices an intrusion coming from Arkadia. Jaha suggests that it is either Jacapo Sinclair or Monty Green, but ALIE informs him that Sinclair is dead. Jaha tells ALIE he has a way to distract Monty and gets Hannah. The plan is almost a success until Monty deletes his mother's code refusing to have her used again him in such a way. Jaha urges ALIE to pull out of Arkadia but ALIE says it unwise since if she does the mobile backpack unit would be her sole power source. As the intruder gets inside ALIE's citadel she finally pulls from Arkadia after migrating to the Ark. Jaha informs ALIE that everything could have been destroyed today but ALIE tells him not to worry.

In Perverse Instantiation (Part 1), Jaha exits the Polis tower to greet Roan and Clarke and asks that Clarke give him the flame. When Clarke refuses and tries to run he has guards take her to the top of the tower. Jaha watches as Abby tortures Clarke in an effort to get the passphrase for ALIE 2.0. ALIE then informs Ontari that she must not let Clarke unchip her and give her the flame. Ontari complies and Jaha strikes her in the head, rendering her brain dead. Bellamy then shoots Jaha but not fatally.

In Perverse Instantiation (Part 2), Jaha is in the throne room still commanding the chipped army. In the City of Light, he informs Clarke she has nowhere to run and needs to surrender herself to ALIE. Clarke, who is with Lexa, fights back and Lexa attacks the approaching City of Light residents. Later, after Clarke terminates the City of Light, Jaha awakens in pain.

Personality Edit

Jaha is portrayed as a strict, trustworthy, organized and understanding person. He is tough to those that have a problem with him. However, he cares deeply for the citizens of the Ark and is willing to put himself in danger for their safety. He tries to avoid giving himself special treatment, even allowing his son to be part of the 100, and almost becoming part of the Section 17 volunteers.

Physical Appearance Edit

He has black hair and brown eyes with a dark skin tone, similar to his late son, Wells Jaha.

Relationships Edit

Wells Jaha Edit

Main article: Thelonious and Wells

Wells was Chancellor Jaha's only son. When it appears that Wells has died, due to Bellamy and his friends forcing him to take off his wristband, the Chancellor appears to be very distressed. In Contents Under Pressure, he learns his son has actually been killed and he hides his anguish. Later, however, he snaps at one of the family members of the Section 17 volunteers when they tell him that he doesn't understand what they're going through.

After taking the Key to the City of Light, Thelonious no longer remembers that Wells ever existed, as the Key took away the pain of his son's death and by default took away any memory of Wells so he never knows Wells was ever alive, let alone dead.

Abigail Griffin Edit

Chancellor Jaha cares about Abby. They generally tend to agree, but there are times where they disagree. For example, Abby is more optimistic about the 100's chances than he is. She saved his life after he was shot by Bellamy, risking her own in the process. In return, he stopped Kane from executing her. They both care deeply for their children who are on the ground.

Marcus Kane Edit

Councilman Marcus Kane is Chancellor Jaha's second-in-command. Despite this, the two often disagree. Jaha has expressed that he thinks that Kane may have been involved somehow in the plot to kill him. But, Kane has appeared to care about Jaha, advising him not to take his own life with the 320 whose lives will be taken.
