I think Caroline’s biggest struggle is parallel to Stefan’s biggest struggle. This is a season of Caroline just really wanting to do the right thing, and to do the right thing by the people that she cares about. It coincides with Stefan, who just wants so hard to do the right thing and to have Elena grow and experience being a vampire in a perfect, safe, right way. He’s almost re-doing the way that he became a vampire through Elena. He’s getting another chance, and he wants things to go a certain way, even if it’s not necessarily the best thing for her, he wants it to be right. Caroline wants to be strong and support Tyler, but she doesn’t necessarily believe in supporting him. She’s not sure that he’s going about things the right way, so she’s conflicted. He’s potentially risking his life, and she doesn’t like that, and Stefan is feeling the same way about Elena. I think that’s where the bond of friendship comes from. They’re both trying to support the people that they love, even if they don’t agree with how they’re going about their lives at the moment. There’s a really beautiful friendship that is continuing to grow from Season 2 — it took a vacation for a minute, but the roots are still there, and we’re able to watch it grow now.
