There has been a bevy of shocking moments on American Horror Story, but which ones did the cast find especially traumatic? We caught up with the show's stars at the LA premiere over the weekend, and we asked them to spill on the scenes that scarred them for life. Some of the newer members, like the handsome Matt Bomer, had a particular scene in mind. But veteran cast members like Evan Peters had more than a few to choose from. Find out what they said, and gear up for the season five premiere on Oct. 7.
