After discovering Langdon's plan for the Outposts, the Coven decide to hide Coco and Mallory in Outpost 3 by giving them new identities, and making sure they survive the apocalypse while Mallory's powers are growing. After discovering Dinah's involvement with Langdon, Cordelia, Myrtle, and Madison bury themselves in the swamp mud to survive the nuclear blast.
In the present day, the Coven face Langdon. As Dinah pledges allegiance to the Antichrist, a newly regenerated Marie Laveau kills her for her betrayal. Cordelia then destroys Mead while Madison shoots Langdon to buy time for Mallory to cast the time travel spell. While Langdon kills Madison, Marie, and Coco, Mallory is stabbed by Brock, prompting Cordelia to sacrifice herself to allow Mallory's rise as the new Supreme. Mallory casts the spell and returns to 2015, where she runs over a younger Langdon multiple times, killing him and preventing the future events.
Mallory eventually returns to Miss Robichaux's Academy, saving Queenie, Misty, and eventually Madison from their previous fates. Meanwhile, Timothy and Emily meet in the new present and, years later, have a son together, who later kills his nanny. Anton LaVey, Samantha Crowe, and Mead visit them, claiming that they came to help.
