Damon Salvatore: Cute pj's.
Elena Gilbert: I'm tired, Damon.
Damon Salvatore: Brought you this.
[holds out her necklace]
Elena Gilbert: I thought that was gone. Thank you.
[about to take necklace, but Damon pulls away]
Elena Gilbert: Please give it back.
Damon Salvatore: I just have to say something.
Elena Gilbert: Why do you have to say it with my necklace?
Damon Salvatore: Because what I'm about to say is... probably the most selfish thing I've ever said in my life.
Elena Gilbert: Damon. Don't go there.
Damon Salvatore: I just have to say it once. You just need to hear it. I love you, Elena. And it's because I love you that... I can't be selfish with you. And why you can't know this. I don't deserve you... but my brother does.
[Kisses her on her forehead]
Damon Salvatore: God, I wish you didn't have to forget this... but you do.
[Compells her]
