Nathalie, Bruno’s grandmother and Father’s mother, was a singer in her youth, before she married Grandfather. She is very dramatic, and still loves to sing. Each Christmas, she devises a play for herself and the children, to be performed at their holiday party. Grandmother opposes the Nazi party, and gets into a huge fight with Father when he accepts the new post at Auschwitz. They do not make up, and she dies while the family is away at Auschwitz.
