Ryan Kelley's character Jordan Parrish has been through a lot this season, from learning that he is a hellhound to finding out that he is supposedly dead. The actor previewed the much-anticipated fight between the hellhound and the Beast and teased that only one of them will come out alive.

Kelley told TVLine: "It looks like Parrish and the Beast are going to square off with only one of them surviving. Will Parrish even make it out alive? And if he does come out victorious, what's his purpose? Not to mention he's supposedly dead already, as we heard that 'Jordan Parrish is no more.' There are a lot of factors in play here."

According to 29-year-old actor, being a hellhound surprised him more than the fact that he is dead. Ryan told the website: "Probably being a hellhound. Even though Parrish is technically 'dead' — and I'll admit don't really know where that storyline is going — I have to imagine that he's somehow still around, at least part of him. This is Teen Wolf, so if there's any way he could come back, I'm sure he will." A previous report suggested that a major character is set to die in this episode.
