Plot summary
On Bardo, Bellamy convinces Cadogan to spare his friends in exchange for his help in finding and repairing the Flame to begin the last war; when the others refuse to help, Bellamy allows their memories to be scanned, leading to a tense confrontation with his friends. Clarke eventually offers to help Cadogan if he frees the others, but he sends everyone but Raven and Gabriel to a different planet instead to ensure Clarke's compliance. On Sanctum, Sheidheda massacres the Children of Gabriel when they refuse to kneel although Luca survives and is rescued by Indra.
Taking up residence in the machine shop, Murphy and Emori work to protect the survivors of the earlier massacre; although Nikki finds them, she is captured and Murphy seemingly talks her down using the memory of Hatch. Sheidheda locates the group hiding in the reactor and takes Murphy captive, but Emori threatens to detonate the reactor if he attacks, creating a stalemate. Clarke returns to Sanctum with Raven, Bellamy, Gabriel, Doucette and Cadogan and is shocked by the carnage that she discovers.
