STEFAN: I hope Damon didn't drive you too crazy. 

ELENA: No, actually, he was on good behavior. He even apologized and explained why he is the way he is. And it all goes back to Katherine. 

STEFAN: Hmm. 

ELENA: So tell me about her. What happened? 

STEFAN: It's not something I like to talk about. 

ELENA: I get that. I do. I just want you to know that you can. I mean, I burden you with all of my drama, and I want you to do the same.
