Things are just getting started on Teen Wolf.

In an extended sneak preview of the MTV supernatural drama's Jan. 13 episode, which The Hollywood Reporter exclusively debuts, as the gang continues to deal with the effects of the ritual sacrifice, a frantic Stiles (Dylan O'Brien) asks, "What the hell is happening to me?"

"I'm straight-up losing my mind," he later says in voiceover as letters start to fall from an open book on a table.

Meanwhile, his best friend, Scott (Tyler Posey), is dealing with troubles of his own when he's told to harness his inner beast -- "Become everything you're afraid of!" -- before he's bloodied to a pulp: "What if I can't control it? What if I can't turn back?" To make matters worse, Allison (Crystal Reed) is being haunted by her aunt Kate.

The action in Beacon Hill seems to culminate in a climactic battle with the werecoyote, and Sheriff Stilinski (Linden Ashby) is seen urging Stiles and Scott to keep things quiet.
