Plot summary
Maxwell's brother, Nigel, returns to throw him a bachelor party, and Fran is terrified because Maxwell doesn't know that she almost married Nigel a year–and–a–half earlier. She tries to keep the secret, but Nigel gets drunk at the party and reveals all to Maxwell just as Fran pops–out of the cake in a surprise. (Sylvia earlier confessed that Morty cancelled his wedding and ran off with the cake girl at his bachelor party - Sylvia!) Fran and Maxwell quarrel over Nigel's revelation, and cancel the wedding, until C.C. (under the influence of Prozac ) tells Fran that "Maxwell didn't spend 5 years doing the one man show" and reveals one of his liaisons. Fran contacts Marla Maples, who had a quick fling with Maxwell a year and a half ago, to confront him. Fran and Maxwell finally realize they love each other and resume the wedding plans.
