The Vampire Diaries, Season 4

Elena:
What the hell are you doing here?

Katherine:
Your boyfriends invited me. They want to know if you still have a heart. There it is. Your bodyguards won't let me kill you, but I can rip your throat out. So I don't have to listen to you whine. But first, satisfy my curiosity,what did you tell Elijah back in Willoughby?

Elena:
That's why you're here? He dumped you, didn't he? Now you're just looking for a scapegoat.

Katherine:
Tell me what you said to turn him against me or I will feed you your own eyeballs.

Elena:
I didn't have to say anything. Look at you. A self-obsesses egomaniac on the run for 5 centuries. What good would you be to anyone? You're the definition of damaged goods. No wonder Elijah left you.

Katherine:
Yeah, I've done some pretty horrible things to survive, but unlike you, poor, delicate Elena, I don't turn it off. I deal with it. You wouldn't last a week as a vampire without everyone fawning over you. By I'd love to see you try.
