Get ready to howl with joy, Teen Wolf fans! The second half of this season is about to get even crazier, because the MTV drama is adding yet another killer into the fray.

Sinewy Hellboy actor Doug Jones is going to show up in Beacon Hills on Episode 15, titled “Galvanize” as a known killer named Barrow. The details are sketchy, so we don’t know yet if Barrow is going to be a human, a werewolf, or something else of the supernatural variety — but we’re excited!

Jones is a favorite of fantastical Director Guillermo Del Toro, and has appeared in a ton of creepy roles, including the haunting “Fauno” and the eyeless “Pale Man” in Pan’s Labyrinth. He also gave viewers the shivers as a nightmarish “Gentlemen” in one of Buffy the Vampire Slayer’s most popular episodes, “Hush.”

Sounds like he’s the perfect fit for the Teen Wolf world! But how will Scott, Allison, Stiles, and Lydia handle this new threat? We can’t wait to see what happens when Doug joins the cast of the show after it returns from hiatus on January 6.
