American Horror Story writer Douglas Petrie confirmed the setting of the series' fourth season: a presumably very spooky carnival. (All you fans guessing "Hell Circus" weren't far off!) Petrie was a guest on the podcast Nerdist Writers Panel, moderated by Ben Blacker, which was recorded February 16 and released just a few days ago. Petrie was on the panel with a few other television writers, and he starts talking about the fourth season by saying, "I can't say anything." But when Moira Kirland, a writer on Arrow and Castle, offers that she heard a rumor about the season, Petrie confirms it. The revelation happens around minute 33; you can listen to the whole podcast here.
Now it is time for your predictions and theories to commence. Let the circus begin.
