Will Derek Choose To Save Stiles? Tyler Hoechlin Talks Evolving Relationship On 'Teen Wolf'

Stiles' (Dylan O'Brien) mind has been taken over by the Nogitsune, and Teen Wolf's comedic relief now has viewers on the edge of their seats. Don't worry though, Tyler Posey (Scott) is adamant that, as bad as things are with Stiles, the true villains of the season are the demonic ninjas.

"The ninjas are definitely the main villains of the season," Posey explained to E!. "You'll definitely see [Stiles] go more in the direction that you can already see him going in. Of course, it's Teen Wolf, so we're going to pop up with a couple of different villains in there, so there's no shortage of evilness to come."

"I can tease that were not sure yet if Stiles is really off the rails or not," Davis said on Wolf Watch. However, his current state will definitely "last a little while."

Viewers will soon find out more about the Nogitsune, however, including why its face is completely bandaged. Hint: it has something to do with Japanese internment camps.
