"Elena: Tell me what Qetsiyah said back at the cabin.
Damon: She told me that...we don't stand a chance.
Elena: And what does she know about us?
Damon: Well, she told me a very interesting little story about the history of Doppelgangers; how they're fated to fall in love with eachother. Basically, the universe programmed you to fall in love with Stefan, not me. Which means...we're a lost cause no matter what we do. (pauses) I'm paraphrasing
Elena: ..."The universe"?
Damon: Her words, not mine.
Elena: So...she's crazy.
Damon: Maybe. Maybe she's not...
Elena: Look. I know I spent the last couple days focusing on trying to find Stefan, but that has nothing to do with how I feel about you, and I'm not gonna let Silas' 2,000-year-old ex-girlfriend screw things up between us.
Damon: You think I am? I mean, no one tells me how I live my life, no one tells me who I love. Especially not some vindictive, prehistoric witch and definitely not the universe. And I'm not gonna let someone else's idea of destiny stop me from loving you, or being with you, or building a future with you, because...you are my life."
