Dr. August Steiner • Dr. Alec Munsell • Mr. X
- Mr. X: [as Hart is restrained on the operating table] I am just going to cut away your shirt. You don't mind? The pain when I am going through the layers of skin will not be unendurable. It is only when I am able to cut on the inside that you will realize you are having... an experience.
- [He cackles under his surgical mask]
- Mr. X: Wasn't it Nietzsche, who said that unendurable pain merges into ecstasy?
- Jim Henderson: [as Henderson goes into X's lab] Hello, Doc!
- Jim Henderson: [X turns the noisy machines off] How's the old throat specialist?
- Mr. X: It will be a pleasure, Henderson, to work on your throat... someday.
- Jim Henderson: [He laughs nervously] No, thank you, Doctor.
- Jack Hart aka Quinn: I'll guarantee this: no matter what happens to me, this butcher shop won't be here tomorrow.
- Mr. X: Neither will you.
