Stiles Stilinski has been an integral part of Scott McCall's Teen Wolf pack since the very beginning (never forget the early high school years!) — and when the long-running series returns this fall, the witty, outspoken teen will be right in the thick of all of the lycanthrope action.

In an inaugural look at the upcoming season, we can happily unveil the first image of Dylan O'Brien's on-screen alter ego during a dramatic scene (featured above) in the premiere episode. HE'S BACK!

“Stiles is a big part of the season because a lot of this season’s mystery revolves around him,” executive producer Jeff Davis told Entertainment Weekly. “We’re going to see just what Stiles’s friendship means to Scott, Lydia, and Malia.”
