RACHAEL: Have you ever retired a human by mistake ?
Deckard hesitates before answering the question.
RACHAEL: But in your position that is a risk?
TYRELL (OS): Is this to be an empathy test? Capillary dilation of the so-called blush response. . . fluctuation of the pupil . . . involuntary dilation of the iris.
DECKARD: We call it Voight Kampff for short.
Deckard turns to see an older man, very distinguished, very well tailored, has entered the huge marble office. TYRELL!
RACHAEL: Mr. Deckard. Dr. Eldon Tyrell.
TYRELL: Demonstrate it. I want to see it work.
DECKARD: Where's the subject?
TYRELL: I want to see it work on a person. I want to see a negative before I provide you with a positive.
DECKARD: What's that going to prove?
TYRELL: Indulge me.
DECKARD: On you?
Tyrell indicates Rachael.
TYRELL: Try her.
Deckard looks at Rachael. She's a beauty alright.
DECKARD: It's too bright in here.
Tyrell hits a button. The windows darken, a polaroid effect that seems to give Tyrell the power to turn off the sun.
Deckard is placing the Voight Kampff case on the table. The Voight Kampff opens like a butterfly as the room darkens.
RACHAEL: Do you mind if I smoke?
DECKARD: It won't affect the test. All right, I'm going to ask you a series of questions. Just relax and answer them as simply as you can.
Rachael's eye fills the screen, the iris brilliant, shot with light, the pupil contracting. We hear Deckard's voice and we have the impression the test has been going on for a while.
DECKARD: It's your birthday. Someone gives you a calfskin wallet.
RACHAEL: I wouldn't accept it, also I'd report the person who gave it to me to the police.
DECKARD: You got a little boy. He shows you his butterfly collection, plus the killing jar.
RACHAEL: I'd take him to the doctor.
DECKARD: You're watching television. Suddenly you realize a wasp is crawling on your arm.
RACHAEL: I'd kill it.
DECKARD: You're reading a magazine, you come across a full-page nude photo of a girl.
RACHAEL: Is this testing whether I'm a replicant or a lesbian, Mr. Deckard?
DECKARD: Just answer the questions please.
Tyrell looks on in silence with his all knowing smile. The scene implies time passes.
DECKARD: You show it to your husband. He likes it so much, he hangs it on your bedroom wall.
(Secondary dialogue fade in/Deckard: ...bush outside your window...)
RACHAEL: I wouldn't let him.
(Secondary dialogue fade in/Deckard : ...orange body, green legs...)
DECKARD: Why not?
RACHAEL: I should be enough for him.
DECKARD: One more question. . . You're watching a stage play, a banquet is in progress. The guests are enjoying an appetizer of raw oysters. The entree consists of boiled dog.
Rachel has no response and looks away. Deckard switches off the instrument's beam. They just look at each other for a moment.
TYRELL: Would you step out for a few moments, Rachael?
Rachael exits looking a little shaken. What's going on? Deckard stares at Tyrell.
TYRELL: Thank you.
DECKARD: She's a replicant . . . isn't she.
TYRELL: I'm impressed. How many questions does it usually take to spot one?
DECKARD: I don't get it, Tyrell.
TYRELL: (insisting) How many questions?
DECKARD: Twenty, thirty cross referenced.
TYRELL: It took more than a hundred for Rachael, didn't it.
