The thing that got me excited is more of a spoiler for sure --
Season three opens the door to learn more about Klaus and The Original Family as his motives for wanting Stefan on his side are finally revealed. As Stefan sinks deeper into the dark side, Damon and Elena struggle with the guilt of their growing bond even as they work together to bring Stefan back from the edge. The ghosts from Jeremy's past have a powerful message they're trying to deliver to him, not to mention the impact they're having on his relationship with Bonnie. And as Caroline and Tyler grow closer, a war erupts between their families.
SQUEEE!!! So (a) Damon isn't going to be a jerk trying to steal Stefan's girl while he's on a bender, (b) if they're feeling guilt then those feelings are REALLY there and so not platonic, and (c) (in my best Chandler Bing voice) could it BE any more obvious that Damon and Elena are THE love story?
So, again, SQUEEE!
