Her brother, Frieder, and Charlotte find her, but she does not come home with them. After all the old windows have been removed, Frieder rejects the replacement ones that are delivered. Frieder has a liaison an old girlfriend Maria, who is now Charlotte's nursery school teacher. Nina returns to the house without windows.
