WATKINS: Vaughn, obviously I can't choose but to work for you. If I refuse, you'll torture me or kill me. I know I can't stand up to torture, and I don't want to die. You're an evil man, Vaughn. You're sadistic. You're a megalomaniac. You're insane. I pity you, but if I get half a chance, I'll kill you.

VAUGHN: Kill me? Would you? Give me your gun, Packer.

( Packer gives Vaughn his pistol. Vaughn points it at Watkin's head then turns it round and offers it to him.)

VAUGHN: Take it. There you are. Take it.

(Vaughn puts the gun in Watkins' hand. Gregory and Packer and the guard back away.)

VAUGHN: Now you're free to shoot me, Professor. Shoot. Shoot!

(Vaughn knocks Watkins down.)

VAUGHN: Come on, the gun's loaded, or haven't you got the courage to pull the trigger?

(Watkins gets up and fires three times, point blank, then faints. Vaughn has three smoking holes in his shirt, but is standing there laughing.)

VAUGHN: Take him away. Get work started on the machine immediately.
