Complete story — includes the ending
The black rain begins to fall, and as the Sky People shelter in the remains of Arkadia, Bellamy tries to rescue a father and son trapped outside, but is unable to reach them. Octavia and Ilian take refuge in a cave, but when he tries to get her to open up about Lincoln, she tries to go into the black rain and kill herself, but he stops her. They have sex, and she decides to go with him back to his family's abandoned farm. At the underground lab on Becca's island, Abby tells Clarke about her new plan to implant Luna's bone marrow into a test subject to see if it can create immunity, but to test this they would need to use a huge dose of radiation on the subject, which could kill them. When a grounder thief breaks into Becca's mansion and is captured, Emori identifies him as her nemesis Baylis. She intends to kill him, but Clarke decides to use him as the test subject. Emori later admits to Murphy that the thief is not Baylis, and that she lied to save herself from being sacrificed.
