Harry Enfield is Prince Charles and he's trying to keep his clan in order, but Wills wants to mingle with the people.
Meanwhile, Kate is keen to impress her new family, so she offers to help Harry with his fancy dress ball at Buckingham Palace, and Pippa's very jealous her sister's bagged herself a prince, so is out to lure Harry.
Elsewhere, Fergie's determined to party with her daughters Beatrice and Eugenie, and Camilla's alarmed at Kate and Wills' popularity and comes up with a series of very optimistic plans to derail them.
