First of all, I'd like to say that I loved the season finale , regarding that I can almost fully agree with Slade, however I didn't really like Elena without her humanity. The writers have built her character upon that compassion and love towards others and without that, in my opinion, she was too similar to Katherine....
As for Caroline and Klaus, I loved their scenes, I've loved them from the beginning and that scene after the graduation at the school was one of the best they had. Sadly, Joseph Morgan has signed to "The Originals" for next fall so Klaus will most likely not be in TVD next season at all. The episode in New Orleans was meant to be the backdoor-episode for the spin-off with creating Marcel and the witches' characters. Also Hayley's pregnancy is very interesting I think (as dramatic and moving the scene where they tell him he's going to be a father is, I was instantly reminded of that scene between Damon and Elena in Georgia where Damon has that line "Vampires can't procreate....but we love to try."), I hope it will bring out the part of Klaus that cares about family, the part we saw when Mikael hurt him so bad (->"Nobody cares about you anymore, boy.", or something like that).
What I REALLY can't see happening is that Camille-girl as Klaus's love interest in The Originals, I mean she really reminds me of Caroline in some ways and I'm not quite sure if that will work.....
