'Vampire Diaries' Star Michael Trevino Previews His Turn As Klaus

Spoilers ahead if you haven't watched the season three finale of "The Vampire Diaries"!

Earlier this week, we caught up with "Vampire Diaries" stars Ian Somerhalder, Nina Dobrev and Paul Wesley to find out what will become of Elena's compelled-away memories now that she's become a bloodsucker. But our protagonist wasn't the only one left transformed in the season three finale. As you'll recall, villainous vamp Klaus took over Tyler's body. What will this mean for the werewolf and the vampiress who loves him?

"It's going to be very interesting," Tyler's real-life alter ego Michael Trevino told us recently at Comic-Con. "We're just about to finish the first episode of our fourth season. What's really important is the interaction between Klaus-Tyler and Caroline now. Because that's a love triangle within itself, and Klaus is totally going to take advantage of being in Tyler's body, and he totally pushes the limit, especially in the first episode when we come back, so we're going to tackle that right away."

Klaus, pushing limits? How unheard of! But all joking aside, how long can we expect this body-snatching to last?

"I don't know how long I'm going to be able to play Klaus," Michael said. "You figure, Joseph Morgan is a big part of our show. He's a fan favorite, so Klaus is going to come back sooner rather than later, but it is going to stir the pot a bit with him being Tyler and interacting with Caroline.

"I think season four is finally the time we finally figure out who she is going to chose. Is she going to go with Klaus? Is she going to go with Tyler? Or neither? Because that triangle has been in existence for a while now."

Whatever happens, Michael insisted Caroline will make a decision and it won't be both. Too bad.

Which suitor do you think Caroline should choose? Are you excited to see Michael play Klaus? Sound off in the comments and on Twitter!
