American Horror Story Episode 8.07 Apocalypse: Traitor

With the help of voodoo queen Dinah Stevens, Cordelia arranges a meeting with Papa Legba in an attempt to prevent Langdon's plans. Legba reveals that he owns Nan's soul, and agrees to help entrap Langdon under the condition that Cordelia give him the souls of the remaining girls. Cordelia refuses, and Legba disappears.

In order to learn more about the warlocks and their plans, Madison enlists the help of Myrtle's long time friend, witch-actress Bubbles McGee, who specialises in reading the thoughts and souls of others. At a dinner party held by Myrtle, Bubbles discovers that Ariel and Baldwin know about the death of John Henry, and that they are planning to kill the women of the coven. Zoe suspects Mallory to be the true next Supreme after she saves Coco from choking and confides in Cordelia.

Later, Mallory passes the Seven Wonders after successfully resurrecting John Henry. The coven then capture Ariel, Baldwin, and Mead, and burn them at the stake for their betrayals.
