Deckard: I was quit when I came in here. I'm twice as quit now.
Bryant: I need the old Blade Runner. I need your magic.
Rachael: Have you ever retired a human by mistake?
Rachael: Is this testing whether I'm a Replicant or a lesbian, Mr. Deckard?

Rachael: You know that Voigt-Kampf test of yours? Did you ever take that test yourself?
Bryant: Christ, Deckard, you look almost as bad as that skin-job you left on the sidewalk.
Dr. Eldon Tyrell: "More human than human" is our motto.

Gaff: It's too bad she won't live. But then again, who does?
Roy Batty: Quite an experience to live in fear, isn't it? That's what it is to be a slave.
Roy Batty: I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhauser gate. All those moments will be lost in time, like tears... in rain. Time to die.
