The Vampire Diaries, Season 2

Elijah:
Good evening, Katerina. Thank you for having the good sense to be frightened. (to Stefan) Your release has been requested.

Stefan:
What? By who?

Elijah:
The lovely Elena drives a hard bargain. However, we reached a peaceful agreement, she and I. Please, come.

Stefan:
I can't.

Elijah:
Yes, you can. I've had the spell lifted.

(Stefan exits the tomb. Katherine tries to escape but Elijah stops her).

Elijah:
As for you, however... You shall not exit until I say so. When Klaus comes he'll want to know exactly where you are. (to Stefan) You're free to go. Elena will explain the arrangement to you. If she keeps her word, I'll keep mine.
