Or she would be if series creator Ryan Murphy hadn't removed the last page from the actress' episode 13 script.

"We actually just got episode 13 and the last act is missing ... they don't want us to know." Roberts (Chanel) teased, according to Entertainment Weekly. "So I think we'll be left until the last couple of days to find out who the killer is and why and what the setup's gonna be for next year."

Take heart, viewers, even the cast had to go through the entire first season without knowing who is hiding behind the Red Devil's mask.

"They get everything but the last act, because I don't trust them," Murphy explained to Entertainment Weekly.

Although it may sound like it, the untitled ep won't close the season with little to no explanation. The audience, and the characters, will fully understand the killer's motives and strategies before Scream Queens heads into its first hiatus.

"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 said. "So lots of flashbacks, lots of twists and turns."
