The Vampire Diaries, Season 2

Damon:
You're surprised that I thought you'd kiss me back - you can't imagine that I'd believe that you'd want to?

Elena:
Damon...

Damon:
That what we've been doing here means something? You're the liar, Elena. There is something going on between the two of us and you know it. And you're lying to me, and you're lying to Stefan, and most of all your lying to yourself. I can prove it.

Elena:
No-

Damon:
(kisses her)

Elena:
Damon don't. What's wrong with you?

Damon:
Lie about this. (tries to kiss her again)

Elena:
Stop it. You're better than this, come on.

Damon:
That's where you're wrong.

Elena:
No, no, no, Damon...I care about you. Listen to me, I care about you! I do. But I love Stefan. Its always gonna be Stefan.
