McCoy: Well, you must be very unhappy, Mister Spock.
Spock: That is a human emotion, Doctor, with which I am totally unfamiliar. How could I be unhappy?
McCoy: Well, we found a whole world of minds that work just like yours. Logical, unemotional, completely pragmatic. And we poor, irrational humans whipped them in a fair fight. Now you’ll find yourself back among us illogical humans again.
Spock: Which I find eminently satisfactory, Doctor, for nowhere am I so desperately needed as among a shipload of illogical humans.
Kirk: Touché, Bones.
McCoy: Leave me here, Spock.
Spock: We go together or not at all.
McCoy: Don’t be a fool. My hands and face are frostbitten. I can’t feel my feet. Alone you have a chance. Now do what I say. Go try to find Jim.
Spock: We go together.
McCoy: You stubborn, thickheaded Vulcan!
