In We Are Grounders (Part 1), Raven is in the process of building the landmines and planting them around camp, as well as making bombs. She is interrupted when Murphy holds Jasper, and later Bellamy, hostage in the dropship and has to find a way to open the door. Raven slips into a hatch under the ship and is able to open the door but gets shot by Murphy in the process causing nerve damage in her leg.
In The 48, a Grounder is seen inspecting the bodies outside the dropship. He walks inside the dropship where he sees Raven. Presuming she is dead, he flips her over but she shoots him instead. She hears someone coming and gets ready to shoot again before seeing it is Murphy. He asks her not to shoot but she pulls the trigger multiple times anyway, however, there aren't any bullets left. He comes and sits down and says, "I would've shot me too." Raven asks Murphy why he's there and he responds, "Dying, the same as you".
Minutes later, she starts to cough up blood and he rushes to her, trying to help her get on her side. When she asks why he is helping her, he says, "I don't want to die alone." Murphy apologizes to Raven for shooting her. She asks him why he is so psycho. He reveals that his father stole medicine for him to keep him alive, medicine that wouldn't have worked anyway. His father was caught and floated and his mother started drinking herself to death. Before Murphy found her dead, she had told him that it was his fault his father was dead. Later, after the Sky People arrive at the drop ship, Raven tells Abby that Clarke is gone and Abby leaves a message for Clarke on the drop ship before they leave the drop ship to meet up with the other Ark survivors at Camp Jaha.
In Fog of War, two days after Finn's massacre at Lincoln's village, Raven arrives in the outside bar area of Camp Jaha where Clarke and Murphy are seated. She 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.
In Remember Me, Raven wants to give up Murphy instead of Finn because Murphy was also in 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 dropship and Bellamy, Raven, and Clarke will take the front gate.
In We Will Rise, Raven is left with Murphy and Luna while she struggles with her brain condition causing her to have a sudden change of mood resulting in her calling Murphy hurtful names and punching him in the face.
Later on, Murphy offers Raven help and gives her a solution to her problem, and then Raven thanks Murphy for his help which makes him feel a little redeemed.
In God Complex, Murphy begged Raven to stop them from taking Emori, she gave him a look of sympathy. Raven tried to convince Clarke and Abby to stop and find another solution that does not make them murderers. However, when Clarke asks Raven to give them a better idea, Raven is unable to suggest anything.
In DNR, Murphy, Emori, and Raven are joking around and Raven calls Murphy cockroach for fun. Later on, Murphy and Emori grow worried about Raven and how if she is useless, nobody will come back to save them.
Soon after, Miller and Jackson come to their rescue and as Murphy goes to tell Raven he discovers that her brain is failing and that she wants to die in peace by spacewalking. Murphy does not try to convince her to go with them because he knows that is what she wants, he feels deep remorse and apologizes to her while she forgives him. They have a potential last hug and Murphy leaves looking one last time at her.
Raven: "How did you get to be such a dick, Murphy."
Raven Reyes: "How does a kid who's loved by his parents turn into a murdering psychopath?"
John Murphy: "He gets the flu. His father steals medicine that turns out wouldn't help anyway. Gets floated for it and his mother, she starts drinking pretty heavily after that and last words she says to him before he finds her in a pool of her own vomit is that is that he killed his father."
Raven is the only person on-screen to whom Murphy has told about his parents and how they died. Murphy may have told others, including Emori, off-screen. Others already knew the information from when it happened or were told by others who knew.
Murphy shot Raven, causing her nerve damage and disability.
Murphy later apologises to Raven, but only officially forgives him in DNR.
