Ryan Murphy has 'two ideas' for the next 'American Horror Story'

Cast members Lea Michele, Emma Roberts, and Keke Palmer have received the script for the show’s 13th episode, but not the whole thing.

“They get everything but the last act, because I don’t trust them,” creator Ryan Murphy told EW’s Tim Stack at the first-ever EW Fest on Saturday in New York.

So what can fans – and the cast – expect to see in the last episode? “The killer is revealed and we spent a lot of time taking the audience through how the killer got away with what they got away with,” Murphy teased. “So lots of flashbacks, lots of twists and turns.”
