In the first promo, Allison asks if Stiles is really the one causing all this trouble, and Scott is quick to defend his best friend, saying it’s whatever is inside of him that’s doing it. Meanwhile, Peter is lying on the floor, screaming.

In a sneak peek of the episode, we get some cute scenes between Danny and Ethan, and then Kira and Scott. But everything is turned on its head when Coach enters, subsequently getting shot in the stomach with an arrow.

A short TV spot also gives us a little extra footage, including more shots of Isaac collapsing to the ground, the police station blowing up, and the moment at the end between Scott and Stiles that everyone is dreading.

In the extended promo, we see Sheriff Stilinski and Deputy Parrish trying to find out where Stiles has gone. Meanwhile, Stiles tries to convince his friends that it’s actually him — and not the nogitsune — that’s talking to them. He’s holding one of the Argents’ ultrasonic emitters, and we have to wonder what role they’ll play in tonight’s episode.
