Poelzig : [about Joan] You're interested? Werdegast : Maybe. Poelzig : I thought so. Well I'm not. Only spiritually. Werdegast : Spiritually? Poelzig : Tonight, it is the dark of the moon. We shall gather and...You had better come Vitus. The ceremony will interest you. Werdegast : Don't pretend Hjalmar. There was nothing spiritual in your eyes when you looked at that girl. You plan to keep her here. Poelzig : Perhaps. Werdegast : I intend to let her go. Poelzig : Is that a challenge Vitus? Werdegast : Yes, if you dare to fight it out alone. Poelzig : Do you dare play chess with me for her? Werdegast : Yes. I will even play you chess for her - provided if I win, they are free to go. Poelzig : You won't win, Vitus.
