Dr. Willoughby: I'm going to Silver Creek if I have to go alone.
Adams: Why don't you just try that? You'll never be seen or heard of again.
Dr. Willoughby: Would you like to accept that responsibility, Major?
Adams: I don't really know much about women.
Dr. Willoughby: That's very honest. It's rare to find a man who would admit it, Major.
Dr. Willoughby: (to Grover) You're a fool. The worst kind--an educated fool.
Adams: Carol, you better get some rest. This may be a night we'll never forget--if we live through it.
Adams: I just hope you're a good doctor. If there's one thing I don't want to be it's a dead hero.
