Quote context

[...]

- Tonight is the dark of the moon. And we shall gather, and... You'd better come, Vitus. The ceremony will interest you.

- Don't pretend. There was nothing spiritual in your eyes when you looked at that girl. You plan to keep her here.

- Perhaps.

- I intend to let her go.

- Is that a challenge, Vitus?

- Yes, if you dare to fight it out alone.

- Do you dare play chess with me, for her?

- Yes. I will even play you chess for her.

- Provided if I win, they are free to go.

- You won't win, Vitus.

- Hurt?

- Not a bit.

- What happened last night? Did I do anything silly?

- Silly? How could you do anything that wasn't entirely lovely?
