Grey's Anatomy Season 10, Episode 7 is sounding spookier and spookier. The installment — tellingly dubbed "Thriller" — is set to air on Halloween and will feature multiple types of monsters.

Last week, we reported that an actor had been cast to play a "zombie" in the episode. (Those quotation marks seem to imply that the character is not actually undead, which we're really hoping is the case.)

But now, as E! Online reports, the doctors of Grey Sloan Memorial will encounter a different type of beast:

"Are you by any chance a fan of werewolves?" E! spoiler-hound Tierney Bricker writes. "Then you'll be quite happy with an upcoming episode, where a patient will honestly and wholeheartedly believe that he was attacked by a werewolf. We're talking full-blown crazy, begging Dr. [Spoiler] to call the FBI and move him into a quarantined area. Since the doctor treating him is a big skeptic, the situation goes from annoying to dangerous fairly quickly."

Granted, Tierney didn't specify which episode would feature the werewolf storyline, but c'mon. It's got to be the one airing on All Hallow's Eve, right?

Listen, folks. It's Season 10. The writers will have written more than 200 episodes by the time this one airs. They can be forgiven for going a bit loony. (As long as they ensure that a shirtless Taylor Lautner is cast in the role.)

Are you looking forward to the scary episode, or are you just scared it's gonna be bad? Let us know in the comments below, and catch the two-hour Grey’s Anatomy Season 10 premiere on Thursday, September 26 at 9 p.m. ET on ABC.
