- David Quatermain: Anyone who's killed love within himself is capable of doing evil, filling other people's lives with misery.
- Thomas von Gall: What was the matter with that woman?
- Maria von Gall: She'd lost her son.
- Thomas von Gall: How? Are you afraid to tell me?
- Maria von Gall: Yes.
- [long pause]
- Maria von Gall: It was a baby boy, only a few months. At that age, if you're hungry, you scream. If your mother has no milk, you scream. There were thirty of them hiding, the Nazis just above their heads, the life of that boy against the lives of all the others. You understand, don't you, Thomas? This nightmare has to end and never return, and no sacrifice is too great.
- Jürgen Müller: We are at war - the greatest and most conclusive war ever. Do you realize what that means?
- Catherine Lamiel: That it's causing the greatest and most conclusive evil ever.
- Jürgen Müller: War is purification.
- Thomas von Gall: Gregor hated my mother, and now he hates me.
- David Quatermain: What will he do?
- Thomas von Gall: He'll play the spider. He's built his web, and now he'll sit and wait. Sooner or later we'll step on a thread and he'll feel the vibrations.
- Thomas von Gall: You mustn't begin to love people who are going to die. When playing chess, you can't love the pieces during the game, it would be ridiculous. You have to be prepared to sacrifice them.
- Catherine Lamiel: Thomas! What are you saying?
- Thomas von Gall: What grown-ups often do with children, isn't it? Use them and then sacrifice them.
- Thomas von Gall: I have to put the secret in a safe place.
- David Quatermain: Is it that important?
- Thomas von Gall: It's more important than my grandfather's life. It's more important than my mother's. And it's certainly more important than mine.
- Thomas von Gall: I'm not afraid of you any more.
- Gregor Lämmle: Why should you be?
- Thomas von Gall: Because this time, I know either I kill you or you kill me.
- Gregor Lämmle: A child shouldn't talk about death.
- Thomas von Gall: A child talks about what he sees, sir.
- Guard: How do you get to be a chess champion?
- Thomas von Gall: Takes a good memory, sir, and imagination. You should never trust your opponent. You have to be crafty, too.
- Thomas von Gall: I don't believe you're my father.
- David Quatermain: It doesn't matter whether I am or not. I loved your mother more than anyone else in the world.
- Thomas von Gall: My mother didn't love my father. She hardly knew him. I don't think she had much respect for him, either.
- Gregor Lämmle: I believe the little boy is moving towards the source of his secret.
- Jürgen Müller: And the American and the girl will allow themselves to be led by a child?
- Gregor Lämmle: The girl will follow him because she is riddled with guilt. And that moron, like all Americans, enjoys playing the hero.
- Gregor Lämmle: Luckily, suffering and blood have never bothered me, least of all that of children. They are much closer to animals than we are - like little lion cubs.
