“Teen Wolf” might finally give audiences some answers in Season 5, episode 9. Stiles (Dylan O’Brien) figured out that Parrish (Ryan Kelley) is stealing the bodies in episode 8. According to the episode 9 synopsis, Stiles and Lydia (Holland Roden) will try and answer the question fans have been asking for the last year: what is Parrish?

“Stiles and Lydia seek the truth about Parrish,” the synopsis for episode 9 teases. Will they finally learn what he is? Kelley has been teasing the big reveal for weeks and thinks fans will be surprised by the answer.

“I’m a big nerd, so there are a lot of things I’d been speculating about, which I don’t think people would have known,” Kelley told TV Line. “I love everything supernatural, Greek mythology, all that. I had a pretty good handful of things I thought Parrish was, so it didn’t shock me.”

Elsewhere in this episode, titled “Lies of Omission,” Scott (Tyler Posey) will team up with someone. “Scott turns to an unlikely ally for help,” the summary teases. Fingers crossed that it isn’t Theo (Cody Christian), but who else would Scott consider an “unlikely ally” at this point?

Judging from the promo, it looks like Scott will need help protecting the chimeras. “I can’t deal with another body, another failure,” Malia says. Elsewhere in the video, Lydia is seen attacking someone and Hayden worries that the Dread Doctors are coming back for her.
