American Horror Story Episode 8.08 Apocalypse: Sojourn

After breaking down over Mead's charred remains, Langdon is confronted by Cordelia, who informs him that Mead's soul is hidden by a spell. Langdon, unable to bring her back, flees into the forest seeking guidance from Satan. Unsuccessfully, Langdon remains strong, but confused, and is led to an obscure Satanic church in the city. At the church, he meets Madelyn, who brings him to her home and offers him food. At her house, Madelyn tells Langdon that she has secured everything in life by selling her soul. Langdon reveals that he is the Antichrist, and Madelyn takes him back to the church, where the congregation falls at his feet in worship.

Langdon tells his followers that he has no ambition or plan now that Mead is dead, despite their willingness to help usher in the end of times. Madelyn takes Langdon to a robotics corporation, run by engineers Mutt and Jeff, who have sold their souls in the same way the other Satanists. It is revealed that Ms. Venable worked for the corporation before the nuclear blast, and that Mutt and Jeff were responsible for recreating Mead's android.
