Elena and Stefan in “Unfinished Business”

Elena

Lexi found you like this before, in the 20s, and-- and she saved you.

Stefan

And you know what I did after that? I spent 30 years trying to pull myself together. To a vampire, that's nothing. To you? That's half your life.

Elena

I can't give up on you, Stefan.

Stefan

Yes, you can. It's done - that part of my life is done. I don't want to see you. I don't want to be with you. I just want you to go.
