Well, according to sources Michael Trevino will make one more appearance before exiting for the season. I can spoil that he will be back to share one more pivotal moment with Caroline but after that he's gone. Michael might not ever come back to the show, this news will probably be disappointing to people who love the relationship between Caroline and Tyler. Although people who support Klaroline (Klaus and Caroline being a couple) will rejoice, hoping that Klaus will take the chance that is given to him.
Personally I like Klaus as a character, but when he's around Caroline he's different. He's supposed to be the bad guy but he seems so good around her. It's sweet that Caroline brings the good out of him but if he could be bad and have her I think that would be better than pretending to be someone he's definitely not.
According to that Vampire Diaries spoiler, Klaus has an intimate scene in Season 4, Episode 18, “American Gothic.” As Joseph pointed out, “He hasn't really ever kissed anyone! I mean in the form of Tyler he has, but I think he's finally going to get some action. It's going to be interesting.
However it hasn't been confirmed who this scene is with; so Klaroline supporters don't get your hopes up just yet because this show seems to let a lot of those hopes down.
