David: We're all alone here. They waited until everyone was on leave to do this. Reliant is supposed to be at our disposal, not vice versa.
McCoy: Do you want a tranquilizer?
Kirk: Khan, how do I know you'll keep your word?
Khan: Oh, I've given you no word to keep, Admiral. In my judgment, you simply have no alternative.
Joachim: They're still running with shields down.
Khan:Of course! We are one big, happy fleet! Ah, Kirk, my old friend, do you know the Klingon proverb that tells us revenge is a dish that is best served cold?
It is very cold in space.
and...
David:Lieutenant Saavik was right: You never have faced death.
Kirk: No. Not like this. I haven't faced death. I've cheated death. I've tricked my way out of death and patted myself on the back for my ingenuity. I know nothing.
David: You knew enough to tell Saavik that how we face death is at least as important as how we face life.
Kirk: Just words.
David: But good words. That's where ideas begin. Maybe you should listen to them. I was wrong about you. And I'm sorry.
Kirk: Is that what you came here to say?
David: Mainly. And also that I'm proud, very proud, to be your son.
