Damon was definitely using her as his own personal blood bank. You're right, I shouldn't have said slut.

I must have gotten confused

could be. I may not have paid enough attention. I hope they never introduce any more dopples.

The moms that actually cared about their kids have all been killed and/or turned into vampires.

I know who Valerie is. I'm not talking about her. There was a Caroline look alike at the end of the second episode and glass blew into the building when they showed her.

I completely agree about Stefan and Caroline being the most ill-conceived couple ever. They were great, supportive friends with NO chemistry. There's still no visible chemistry and it sure makes Caroline look like a slut when she's slept with everyone who Elena had a relationship with, except she got to Damon first.…

They showed an excerpt from Stefan's diary about meeting the most beautiful woman aka the missing heretic. Then the last scene was a doppelganger Caroline. I was ready to smack someone upside the head.

I'm so disappointed. The random hero hair comments are annoying but forgivable. They didn't start until well into the show and came out of nowhere but whatever.
