We don't know when. We don't know why. We don't know how.

But we do know what Joseph Morgan will be returning to Mystic Falls at some point on The Vampire Diaries Season 5.

TV Guide has confirmed the news, though reps from both The CW and Warner Bros. are mum on just what brings The Hybrid back to town.

It's not hard to guess, though, is it?

Tyler showed up to seek revenge against Klaus on The Originals Season 1 Episode 7, concluding the hour by seemingly making a deal with Marcel.

Prior to that, Tyler split with Caroline.

So what better way for Klaus to both hurt Tyler and satisfy his own desires than by making some kind of move for the beautiful blonde (newly single!) college freshman.

Who can forget, after all, his parting words to Caroline on The Vampire Diaries Season 4 finale, regarding Tyler?

"He's your first love. I intend to be your last."
