Finally , the cat was let out of the blood-soaked bag! During the two-hour Season 1 finale of “Scream Queens,” which aired Tuesday night, the mysterious Red Devil killer was officially unmasked (after a few deaths, of course). And to our surprise, the Kappa Kappa Tau sorority sister behind all the gruesome deaths was none other than Hester/Neck Brace/Chanel No. 6 (Lea Michele) herself!

“I really wasn’t thinking I was the killer at  all,” Michele told TVLine, noting that due to her relationship with the show’s co-creators (Ryan Murphy, Brad Falchuk and Ian Brennan) she was sure they would have clued her in on the jaw-dropping twist. “I found out when I got the final script. I had no idea leading up to it. I just read the final script and when she says, ‘It was me all along,’ I just went, ‘Oh. My. God.’ I was really excited and, more so, happy to know that she got away with it.”

Although Hester did get off scot-free, Michele confessed that she fears her character’s murderous past may come back to bite her in the butt if “Scream Queens” is renewed for a Season 2. (Fox has yet to confirme if the installment will be picked up for a sophomore series.)

"I've talked to Ryan about what [Hester’s] role would be in the next season being that she was the killer this year,” Lea revealed to E! Online. "And how funny would it be if all these killings started happening again, and if they found out that she was The Red Devil, she could just be like, ‘I'm really NOT doing it this year, I promise?’ We've talked about how she then would unfold into another season."

Well, as we all saw in the final moments of the “Scream Queens” finale, there is another killer -- and, according to reports, it’s definitely not Hester. Michele confirmed to the Hollywood Reporter that Murphy had “mentioned that there will be a new killer next year” and that Hester's head could potentially be on the chopping block. 

“I think she could be in the position of someone coming after her, which would be really fun to play,” she spoke of the potential shift of her character. “This year, it was interesting to have to always play things with it being in the back of your mind that you may be the killer. But to go into another season and potentially be a victim could be fun.” 

Let the theorizing begin!
