The Vampire Diaries - First Crossover With The Originals

Klaus Mikaelson is returning to Mystic Falls, TVGuide.com has learned exclusively.

The Originals' Klaus (Joseph Morgan) will cross over onto The Vampire Diaries for the first time since he exited the series in the Season 4 finale. As part of his goodbye — and in one of our favorite scenes of all time! — Klaus told Caroline (Candice Accola) that her boyfriend Tyler (Michael Trevino) was free to return to Mystic Falls. He then added, "He's your first love. I intend to be your last."

Well now that Tyler and Caroline have pretty much called it quits, has Klaus returned for another go at getting Caroline to give in to his love? Reps for CW and Warner Bros. TV had no comment.

Before the season began, Morgan said he was thrilled with the momentary ending between the two characters, but wasn't sure it was permanent.  "There was a responsibility for the fans who were rooting for Klaus and Caroline to at least give them some sort of resolve," Morgan told us. "That's not saying it's the end of that because there's the potential of crossovers."

When we last talked to Accola, she wasn't overly confident about the two ever getting together. "Klaus is a bit of a bad word for Caroline," she said. "It's a little out of sight out of mind — but he's still there."
