“Teen Wolf” aired its Season 4 premiere on Monday – and you could say it left us howling for more. Jeff Davis managed to fill up the hourlong first episode with nail-biting moments from start to finish as we watched Scott and the gang try to find their missing friend. But nothing – and we mean nothing – shocked us more than the final seconds of “Dark Moon.”

Once the Alpha and Braden located Derek, whom Kate Argent had taken hostage and locked away in an abandoned, villain-filled were-jaguar temple, they came to a shocking conclusion.

“Is that him? Is that Derek?” Malia asked Stiles during the premiere as Scott and Braden dragged a person from the crypts.

“Uh, sort of,” Stiles replied.

That’s when fans saw Derek was no longer the bearded wolf they last saw during the Season 3 finale. Instead he was a hairless, teenage version of himself.

With that said … what’s next for the teens of Beacon Hills? Well, according to the synopsis for episode 2, “117,” the group will be “anxious to put an end to Kate’s plan.” But what exactly is Allison’s aunt up to? Is she still out to destroy the werewolves of Beacon Hills? Or has her supernatural transformation altered her plot of seeking vengeance?

The summary for episode 2 continued that “Scott must team up with an unlikely ally to accomplish the task” of thwarting Kate’s wicked plan.

“Do you have any idea why Kate would turn Derek back into a teenager again?” Scott asks in the promo for “117.”

Apparently Kate decided to take Derek back to an age when he knew her and still trusted her.

“Derek’s been aged backwards. He can’t remember anything,” Scott explains.

Episode 2 of "Teen Wolf" will air on MTV next Monday at 10 p.m. EDT.
