American Horror Story: Roanoke just might be the new gold standard when it comes to a game-changing twist that changes everything—and the reason you could fall off your couch on Wednesday night.

E! News has learned that starting this week, for the first time in American Horror Story (TV?) history, the show's core cast—including Sarah Paulson, Evan Peters and Kathy Bates—will start playing different roles halfway through the season. "It's a radical twist, a completely new form of storytelling," co-creator Ryan Murphy tells E! News of the episode, which catapults the show into an entirely different direction.

Plus, some long-awaited news for fans: Taissa Farmiga is back! And we will finally get to see Finn Wittrock return and play the "most f--ked-up character of all time," according to Murphy, who also teases some deliciousness ahead for fan favorite Evan Peters. Evan and Taissa and Finn and a mind-blowing twist...It's the stuff that (f--ked-up) dreams are made of, y'all.
