Emma becomes a waitress in Kentish Town at a horrible Tex-Mex restaurant, while Dexter becomes a successful television presenter.

Conversely, Dexter's career collapses, going from presenting a mainstream television show, to cable TV, to being fired from a late-night video games review show.
Each of the main characters have relationships with others, such as Emma with an unfunny stand-up comedian boyfriend Ian, and Dexter with a fellow TV presenter. By 2001, Emma has broken up with Ian, and Dexter has divorced wife Sylvie with whom he has had a daughter, Jasmine. The cause of the divorce is Sylvie's infidelity with Callum, one of Dexter's university friends. After the divorce Dexter goes to Paris to visit Emma, where she is writing her second book.
When they meet in Paris, they confront their relationship and whether becoming lovers is the right choice, after all the years they have been friends and with all the complications such a transition would make.
