She is tutored in the ways of the palace by her grandmother, and suffers repeated episodes of an eating disorder. While Charles is abroad, she meets Camilla for lunch, and realizes that she hardly knows Charles at all, while Camilla knows every detail of their relationship. Distressed, she thinks of calling the marriage off.

Margaret tells the Queen that the marriage will be a mistake, but Philip argues that Charles will grow to love Diana. The Queen tells Charles to focus on his duty, and happiness will follow. The marriage goes ahead amid huge public celebrations.
