The Humanich army attacks the compound, killing most of the hybrids. Molly takes a shot for Terra, who escapes, and is saved from Lucy by JD. Molly and Ahdu realize that the few survivors, who have scattered, are all infected with the virus. Dorothy discovers Molly, JD, and a rapidly sickening Ahdu at JD's cabin; initially hostile, she comes to accept that Ahdu is an individual, and she takes over his care without notifying the authorities. JD turns himself in, and Kelsey is released. Molly convinces Nate to provide specialized equipment to treat Ahdu, but Ahdu dies of apparent old age in Molly's arms, outside under the sky per his last wish. Molly begins to show symptoms, and turns herself in to Shepherd. Julie is horrified by the weaponization of the Humanichs. Ethan questions the unfair relationship between humans and Humanichs. Having learned that Humanichs are programmed to "expire" as part of the human experience, Lucy blackmails Charlie with surveillance footage of their encounter and demands to become immortal. He confesses everything to Julie, and they realize that Lucy set Charlie up to learn about Julie and John's affair in the first place. They resolve to deactivate Lucy, but Ethan warns her and she tries to choke Julie. Charlie explains the morality of humans and Humanichs to Ethan, who saves Julie by ripping out Lucy's circuitry.
