SCOTT [OC]: Engineers, man your stations. Engine rooms, report. Cycling station, report. This will be an emergency restart of engines.
KIRK: Where have you been? What happened?
SPOCK: My mother. I could never tell her I loved her.
KIRK: We've got four minutes, maybe five.
SPOCK: An Earth woman, living on a planet where love, emotion, is bad taste.
KIRK: We've got to risk a full-power start. The engines were shut off. No time to regenerate them. Do you hear me? We've got to risk a full-power start!
SPOCK: I respected my father, our customs. I was ashamed of my Earth blood. (Kirk slaps him) Jim, when I feel friendship for you, I'm ashamed.
KIRK: (hitting him repeatedly) You've got to hear me! We need a formula. We've got to risk implosion!
SPOCK: It's never been done! Understand, Jim. I've spent a whole lifetime learning to hide my feelings. (finally hits Kirk back)
KIRK: We've got to risk implosion. It's our only chance.
SPOCK: It's never been done.
KIRK: Don't tell me that again, Science Officer! It's a theory. It's possible. We may go up into the biggest ball of fire since the last sun in these parts exploded, but we've got to take that one in ten thousand chance!
UHURA [OC]: Bridge to Captain. Engineer asked, did you find
KIRK: Yes, I found Mister Spock! I'm talking to Mister Spock, do you understand?
UHURA: Yes, sir. Three and a half minutes left, Captain.
KIRK: I've got it, the disease. Love. You're better off without it, and I'm better off without mine. This vessel, I give, she takes. She won't permit me my life. I've got to live hers.
SPOCK: Jim.
KIRK: I have a beautiful yeoman. Have you noticed her, Mister Spock? You're allowed to notice her. The Captain's not permitted
SPOCK: Jim, there is an intermix formula.
KIRK: Now I know why it's called she.
SPOCK: It's never been tested. It's a theoretical relationship between time and antimatter.
KIRK: Flesh woman to touch, to hold. A beach to walk on. A few days, no braid on my shoulder.
SCOTT: Captain.
KIRK: Scotty, help.
SPOCK: Stand by to intermix. I'll call the formulae in from the Bridge.
