Katherine: Klaus made me call Jenna to lure her out. There was nothing I could do. I didn't have a choice.
Damon: That's why I gave you the vervain, so you had a choice.
Katherine: It was her or me, I chose her.
Damon: I helped you, you owed me. Now when Klaus dies, you're going to walk out of here without a scratch, and Elena's aunt dies. Somehow you're the only one that wins, how'd that happen?
Katherine: I didn't let love get in the way.
Damon: Enjoy an eternity alone, Katherine.

Stefan: They were your friends. They were your family. And you just sold them out.
Katherine: Without blinking.

Elena: And the answer to your question, about our friendship, is yes. You have lost me forever.
Damon: But you knew that already didn't you? You used me today.
Elena: You had information about Katherine that I needed to know.
Damon: I thought friends don't manipulate friends. You and Katherine have a lot more in common than just your looks.

Damon: So what's it going to be, huh? Fight to the death?
Stefan: I'm not going to fight you.
Damon: Why?! I'd fight me.

Damon: I know you love Stefan. And it will always be Stefan. But I love you. You should know that..
Elena: I do.

Hello my lovelies, are we ready?

Klaus

I will always choose you.

Damon

I could have compelled her to behave, but a real ripper enjoys the hunt.

Klaus

It's okay to love them both. I did.

Katherine

Damon: You should have met me in 1864. You'd have liked me.
Elena: I like you now. Just the way you are.

I made a lot of choices that have gotten me here. I deserve to die.

Damon

Damon: Why must you always run from me?
Katherine: Because I know you'll chase.
