There's a new creep clawing its way into MTV's Teen Wolf. "At the very end of the fifth episode, you find out something scary about this new creature — who it is and why it is," star Tyler Posey told me at the MTV Movie Awards. "It has a lot more strength and importance than anyone thinks. It is just hell for us."

And also hell for the actor who plays him. "There is someone in a suit," confirms Posey. "But there is also some CGI involved. It actually scared me. This is something mythical and legendary you have never seen before." That rules out a maenad. Chupacabra, maybe?
