The answer: something altogether different. Peters finally arrived to the show in "Chapter Five" -- and in a most flamboyant, petulant, and curious manner. The intro to the episode introduced us to Edward Philippe Mott, an ancestor of American Horror Story: Freak Show's Gloria Mott, the heiress played by Frances Conroy, and her son Dandy, the serial killer in training.
The character's backstory is operatic in the Murphy mode: a member of the post-Revolution upper crust, Mott fled Philadelphia to Roanoke in search of sexual freedom. By day, he commanded his underlings to build him a house (the house, in the context of AHS: Roanoke) so he could fill it with art. By night, he made love to his black manservant. Well, also by day, too. In the backwoods, Mott was going to do whatever the hell he wanted, whenever the hell he wanted. Needless to say, the Evan Peters fanbase wasn't expecting any of it, but they loved it.
