Stefan and Elena in “Unfinished Business”

Stefan

I'm so sorry.

Elena

We were so stupid. Sneaking around, thinking that we weren't going to get caught.

Stefan

I know.

Elena

We did this... Jenna's in the hospital, and Jeremy could be next. All because we didn't listen to her. Because we're together. Stefan...

Stefan

I know what you’re going to say.

Elena

Then let me say it. I’ve been so selfish because I love you so much. And I know how much you love me. But it’s over, Stefan, it has to be.

Stefan

Elena, I don’t-

Elena

No, Stefan. It has to be.
