So one evening he shows up at the manor of rich Reinhard Staupen to convince him, to let his son join the Staupen's program for special kids. He argues that Herken's forebears once were servants to the Staupen family and that they once went to the gallows for their masters. Staupen, a vile man, refuses and obscenely insults Herken and his son. In a sudden fit of rage, Herken kills Staupen. Noticing that his bloody deed has been caught on camera, he just drops the binder with the evidence about his forebears and leaves, believing he will be arrested in the morning. Enter Balthasar Staupen. Reinhard's disillusioned, cranky son, who finds his father's dead body.
