The MTV star delved into the most enigmatic piece of season 5's first promo (see video below), explaining what Dr. Deaton means when he says, 'The rules have changed."

"There's a new type of supernatural character on the show and they are made by not how you think they're made," Posey hesitantly told Hollywood Life, carefully avoiding any major spoilers. "I don't know if I've said too much."

What new creature could Posey be talking about? While the actor doesn't specifically mention if these new Beacon Hills residents are evil or not, Posey is probably referring to the Doctors.

"As always, we bring in some new mysteries and new monsters," series creator Jeff Davis told TV Line. "I think this season is very much about the line between science and supernatural."
