Now that Klaus has been promised to Caroline that he will live town for good in S05E11,does it mean that they will not see each other ever again?

I'd love it to be true, but I'm pretty sure it wasn't their last scene together, since they have a very large fanbase.

I really hope that it isn't. I mean there is so much potential for the two. They obviously have chemistry, and their actions proved to be more then just puppy love, so I don't think that the writers will completely throw the whole story line away, however with the whole spin off, Klaus has a lot on his mind supernatural, wise, and Caroline has a lot on her mind future, college wise, so I do not think that there paths are going to be crossing anytime soon, however there is definite potential for the future. I love klaroline so much, so I really really do hope that this wasn't the writers way of ending it.

I think it means that although ive only seen up to S05 E09

Ahem, "I may not be your first love, but I intend to be your last." -Klaus

no I think he'll come back to check up on Caroline :)!!!!!!
