Dr. Frank Mannering: I can't do it! I can't destroy Frankenstein's creation. I've got to see it at its full power.

Dr. Frank Mannering: Mr Talbot, if you want us to help you, you must do as we say. Now, please lie down.
Lawrence Talbot: You think I'm insane. You think I don't know what I'm talking about. Well you just look in that grave where Lawrence Talbot is supposed to be buried and see if you find a body in it!

Lawrence Talbot: Why have you followed me?
Dr. Frank Mannering: Talbot, you're a murderer.
Lawrence Talbot: Prove it.
Dr. Frank Mannering: You're insane at times and you know it. You're sane enough now though to know what you're doing. Why don't you let me take care of you?
Lawrence Talbot: You think it would do any good to put me in a lunatic asylum?
Dr. Frank Mannering: You know that's where you belong. It's the only thing to do.
Lawrence Talbot: Oh that wouldn't do any good. I'd only escape again sooner or later.
Dr. Frank Mannering: We might be able to cure you. It might prevent you...
Lawrence Talbot: I only want to die. That's why I'm here. If I ever find peace I'll find it here.

Maleva: He is not insane. He simply wants to die.
