Cancer Man has a telepathic conversation with Mulder, then gives him an injection that takes away the ESP effect and allows him to accompany Cancer Man out of the hospital. Oh, and he says he's Mulder's father. Skinner says it's best if he doesn't know the whereabouts of Scully or the now missing Mulder. Cancer Man tells Mulder that he's entering a sort of witness protection program and becoming a man without an identity. The codetalker, doing much better now, visits Scully and tells her to find Mulder.
Cancer Man takes Mulder to a nice suburban house and gives him the option of staying there or driving himself back to work on the X-Files. Scully realizes that Mulder's mother checked him out of the hospital, but apparently did so after talking with Cancer Man. Much to Mulder's surprise, Deep Throat pays him a visit at the house and says he survived the shooting and lives down the street. Scully gets a book on the sixth extinction that has Native American writing identical to that found on the African craft; she tells Skinner that she thinks Mulder's illness is a protection against the coming apocalypse, and he's assaulted soon after (probably by Krycek) and has something taken from him. Fowley also comes to see Mulder, and they spend the night together; like Deep Throat, she tries to get him to abandon his commitment to the X-Files.
Scully finds that Kritschgau has hacked into her files and had the alien artifacts analyzed by the National Institutes of Health; he says they prove that Mulder has become biologically alien. Mulder and Fowley visit Cancer Man, who says Samantha has been staying with her. We see that Cancer Man actually has Mulder in a secret location and he is merely dreaming. Cancer Man says he's immune to the coming apocalypse, and therefore the savior the Syndicate has been looking for, but might not survive a coming procedure.
In his mind, Mulder flashes through an alternate life and becomes an old man. An unaged Cancer Man says he knows Mulder has been having visions of a boy on the beach, and Mulder has another one: in which the boy has made a sand UFO identical to the one in Africa but destroys it because Mulder was supposed to help him build it. In another vision, unaged Cancer Man tells Old Mulder that his friends and family have all died; he then goes to a window and watches the world outside, which is burning after the alien colonization.
Both Cancer Man and Mulder undergo surgery. Krycek murders Kritschgau, steals his laptop, and torches a bunch of documents. Scully gets a keycard to the Department of Defense from an unknown person. She also appears to Old Mulder in his dream and denounces him as a turncoat, telling him he can't believe this vision and must fight. And then she rescues him from the operating room, the procedure now completed. One week later, Mulder reveals to her that the codetalker was dead when Scully saw him; Scully says Fowley has been murdered, apparently after sending her the book to help her out. The two agents say they're basically the constants in each others lives. In a final dream, Mulder helps the boy build a new spacecraft on the beach.
