[Terrell disobeys Khan's order to kill Kirk, who taunts Khan over the communicator]
Kirk: Khan, you bloodsucker! You're going to have to do your own dirty work now! Do you hear me? Do you?
Khan: Kirk? Kirk, you're still alive, my old friend?
Kirk: Still, "old friend"! You've managed to kill just about everyone else, but like a poor marksman, you keep missing the target!
Khan: Perhaps I no longer need to try, Admiral.
David Marcus: Oh, no! Let go! He can't take it...!
[Khan beams the Genesis device away]
Kirk: Khan... Khan, you've got Genesis, but you don't have me. You were going to kill me, Khan. You're going to have to come down here. You're going to have to come down here!
Khan: I've done far worse than kill you. I've hurt you. And I wish to go on hurting you. I shall leave you as you left me, as you left her; marooned for all eternity in the center of a dead planet... buried alive! Buried alive...!
Kirk: KHAAANNNN!
[echo]
Kirk: KHAAANNNN!
