In her rage, Clarke tells A.L.I.E. that she is going to fry her, accidentally revealing that they plan to use an EMP. A.L.I.E. says she will send somebody to the dropship as that is where there will be an electromagnet.
At the dropship, Monty and Octavia pull up to the dropship. Octavia is upset as she doesn't feel she belongs anywhere as Lincoln was her people. Monty reminds that she is still part of the 100.

Monty is forced to shoot his mother.
Back at Niylah's, Jasper and Bellamy are watching Raven. She begins to make fun of Jasper and calls him a waste of space and mockingly claims that everybody should protect him. Bellamy sends Jasper out and Raven begins to talk to Bellamy about how he is not a leader. Clarke has only been back and day already Bellamy is taking orders. She says that it's a shame he was never very devoted to Gina but says that at least he avenged her by murdering the army of grounders.

Jasper picks up the chip and says he will destroy it. Clarke tries to stop and cries, saying it's Lexa in the flame. Clarke then realizes that she has seen Titus extract an AI before and realizes the key could be extracted in the same way. She cuts open the back of Raven's neck and the AI is taken out. Raven then awakes and is hurt by the cut showing she is un-chipped, much to everyone's happiness.
Monty is upset that he could have saved his mom and when Jasper attempts to comfort him, he rejects him. Octavia gives Niylah a lantern as thanks and Clarke convinces her to go otherwise she will be chipped as well. Outside, Bellamy is upset over the massacre and asks Clarke what to do when you realize you might not be the good guy. Clarke repeats Abby's words that maybe there are no good guys.
