Klaus: I do. But I won't... for you.
Caroline Forbes: So you came all the way to Mystic Falls just to back off when I ask you to?
Klaus: No. No. I came all the way to Mystic Falls to gloat over a corpse to be, as you so poetically put it, but I will leave minus the gloating in return for one small thing.
Caroline Forbes: And what is that?
Klaus: I want your confession.
Caroline Forbes: My confession? I din't do anything... Confession about what?
Klaus: Me. As soon as we're done here, I'm gonna walk away, and I'm never coming back. You'll never again have to look me in the eye and cover our connection with hostility and revulsion. You'll never have to loathe the darkest parts of yourself that care fore in spite of all I've done. I will be gone, and you will be free. I just... Want you to be honest with me.
Caroline Forbes: [almost pleading] I'm in college. I'm building a life for myself. I have plans and a future and things that I want, and none of those things involve you. Okay? None of them.
Klaus: I see.
Caroline Forbes: No, you don't Because yes, I cover our connection with hostility. Because, yes, I hate myself for the truth. So if you promise to walk away like you said an never come back, then, yes, I will be honest with you... I will be honest with you about what I want.
Klaus: I will walk away and I will never come back. I promise.
Katherine Pierce: [weakly] Is this the... 'We're not so different you and I'Doppelgänger speech? Because I'd be happy to skip it.
Elena Gilbert: I'll save it for the funeral we probably won't have for you.
Katherine Pierce: Perfect.
Elena Gilbert: I just wanted to get the forgiveness part out. It's part of me that I... I never want to lose.
Katherine Pierce: Good for you. Now maybe you can help a girl out and give me one more syringe, and if anyone's gonna plunge a needle in me one last time, may as well be you. Symmetry and all that. Elena... Thank you for your forgiveness.
