Sir Percy Heseltine, Home Secretary: The girl he picked up was a nurse named Ellen. As you say, Ellen something or other. He doesn't know her other name, but he dropped her off at Thurlstone Hospital after spending the afternoon with her. He was very reluctant to talk about it. The man's totally exhausted.
Colonel Tom Carlsen: It was the hardest thing I ever did.
Dr. Bukovsky: We understand. It must have taken great courage to try and.
Colonel Tom Carlsen: No, you don't understand. Part of me didn't want to leave. She killed all my friends and I still didn't want to leave. Leaving her was the hardest thing I ever did.
Colonel Colin Caine: But I understand your real interest is.
Dr. Hans Fallada: Death, Colonel Caine, correct. Thanatology's the name for it. Death for you, Colonel, is a bureaucratic problem. Who did it. When, why did they do it. A problem to be solved, am I correct?
Colonel Colin Caine: And for you?
Dr. Hans Fallada: Well, I'm fascinated by death itself. What happens as we die, when we die. What happens after we die.
Colonel Tom Carlsen: She's resisting. I'm going to have to force her to tell me. Despite appearances, this women is a masochist. An extreme masochist. She wants me to force the name out of her. She wants me to hurt her. I can see the images in her mind. You want to stay? Otherwise wait outside.
Colonel Colin Caine: Not at all. I'm a natural voyeur.
Dr. Hans Fallada: I mean, in a sense we're all vampires. We drain energy from other life forms. The difference is one of degree. That girl was no girl. She's totally alien to this planet and our life form... and totally dangerous.
Dr. Hans Fallada: It was two hours ago that the guard was attacked. I wouldn't be at all surprised if we're seeing a pattern here.
