The “Teen Wolf” Season 5 midseason finale is going to be full of reveals for audience members and pack members. However, there is one person the audience knows more about than the pack members: Theo (Cody Christian). Fans discovered Theo’s alliance with the Dread Doctors in the beginning of the season, but it looks like his loyalties will finally be revealed. In a sneak-peek from episode 10, Theo confronts Lydia (Holland Roden), and admits that he isn’t an ally after all.

In the clip, Lydia is seen having some sort of premonition. “You know what’s coming, don’t you?” Theo asks.

“Someone’s going to die here,” Lydia says. She doesn’t say who, so it could be anyone. However, Theo seems to know who it is.

“Right, I can’t let you tell anyone,” he says.

Lydia doesn’t understand. She has to warn someone that there is going to be a death. “I want you, Lydia. I want all of you,” Theo explains.

“What are you talking about?” Lydia asks.

“Don’t worry,” Theo says. “I’ll give you some time to think about it.” He punches Lydia in the face and knocks her out.

Watch the sneak-peek video for the “Teen Wolf” Season 5 finale below:

Theo is likely referring to the fact that he wants Scott’s (Tyler Posey) pack. As previously reported, in promo videos Theo reveals that he wants Scott’s powerful friends, and that he doesn’t need Scott at all.

Theo’s true loyalties won’t be the only reveal in the “Teen Wolf” midseason finale. Fans will also find out what Parrish (Ryan Kelley) is after waiting a year for answers. Is he a phoenix? A hellhound? Something else entirely? Viewers will have to tune in to find out.

“Teen Wolf” Season 5, episode 10, the midseason finale, airs Monday at 10 p.m. EDT on MTV. Whose death did Lydia see? Sound off in the comments section below!
