Will Klaus Be Back Next Season?

Will The Vampire Diaries really kill off Klaus by the season's end? Joseph Morgan hints that's it's a major possibility.

"My character definitely isn't confirmed for Season 4," Morgan tells TVGuide.com. "There's very much a threat he won't make it to Season 4 or even if he does make it to season 4 that it won't be in the way you think. That's a very real threat — I'm genuinely worried by it."

But if Klaus' death means the annihilation of his bloodline (aka our Mystic Falls heroes and heroines), how can the series get rid of him? "I imagine they do something like ... eternity in a box where they keep him alive, but he's no threat to anyone," Morgan says.
