4x7 - Absolutely Fabulous

Upon discovering that Serge is gay and living in New York, Edina is thrilled to reunite with her long-lost son as she plans a trip to New York Fashion Week with Patsy—despite Saffron's objections. In exchange for Serge's contact information, Edina and Patsy are forced to get married by a counsellor at an LGBT drop-in centre where Serge volunteers. Edina finally locates Serge, who works in a second-hand bookstore and, to her surprise, is essentially the male equivalent of Saffron. Despite initially rebuffing Edina's attempts to reconnect due to unresolved issues, Serge is convinced by his flamboyant boyfriend, Martin, to spend the day with her. Edina, Patsy, Serge and Martin attend Fashion Week and later go on a bar crawl. The night ends with Edina and Patsy getting arrested after accidentally setting a bar on fire. The pair return home after Saffron posts bail, and Edina reveals that she has disowned Serge in favour of Martin, whom she has "adopted".
