Have you heard? Klaus is coming.

Yes, 'Vampire Diaries' fans, I know that's all anyone can talk about these days, but come on -- the guy is an Original. We've witnessed some pretty powerful supernatural stuff on that show, but Klaus' arrival will absolutely be the craziest thing we've seen yet.

We hit the Atlanta set of 'The Vampire Diaries' to catch up with the cast and talk all about the O.G. fanged one's arrival in Mystic Falls. Who's met Klaus so far? And who's gone head-to-head with him? "Actually I've just shot one scene with him so far," Paul Wesley revealed. "It was pretty submissive ... one of us was relatively submissive. [laughs]"

Katerina Graham dished about Bonnie's inevitable showdown with Klaus: "She's the one person -- that's been revealed -- that can stop him. ... So I don't think she's expecting to just fly to Hawaii and forget about him for a while."

I know, I know ... no new 'Vampire Diaries' for weeks feels like an eternity living among the undead. But just because the show isn't on your TV doesn't mean you can't hang out with its stars.

We visited Mystic Falls, a.k.a. the 'TVD' set in Atlanta (more on the top-secret episode they were shooting in a few months), to catch up with a vampire, a werewolf, a witch, a kid who can't be killed and the most clueless guy in town. Translation: Caroline (Candice Accola), Tyler (Michael Trevino), Bonnie (Katerina Graham), Jeremy (Steven R. McQueen) and Matt (Zach Roerig).

They dish about last night's fall finale cliffhangers and OG vampire Klaus, plus who's the funniest when the cameras stop rolling and on-set pranks that may or may not involve Ian Somerhalder mooning everyone. Then they humored us a little and answered this burning question: Since several cast members are musically inclined, and music plays such a huge part in the show, any chance you'd be up for a musical episode?
