After 19-year-old Rory Gilmore (series star ALEXIS BLEDEL) sleeps with her former boyfriend, Dean (recurring guest star JARED PADALECKI)—who is married—she argues bitterly with Lorelai (series star LAUREN GRAHAM), who is disappointed by her daughter's choices. Despite her best efforts, Rory cannot resist Dean, even when she guiltily observes how hard Dean's eager young wife is working to keep their marriage together.

Meanwhile, Lorelai copes with a tricky situation of her own: Eccentric resident Kirk (series star SEAN GUNN) has witnessed her kissing recently divorced coffee shop owner Luke Danes (series star SCOTT PATTERSON) after the gala opening of the new Dragonfly Inn, Lorelai's long-awaited venture with her friend Sookie St. James (series star MELISSA McCARTHY). Despite the gossip, Luke and Lorelai seem to finally be happy together.

The longtime marriage of Lorelai's parents, Richard (recurring special appearance by EDWARD HERRMANN) and Emily (series star KELLY BISHOP), continues to crumble. Impulsively, Emily persuades Rory to join her on a European trip. Also, Rory's friend Lane Kim (series star KEIKO AGENA) bickers with her uncontrollable band mates. And Lorelai orders imperious concierge Michel Gerard (series star YANIC TRUESDALE) to get rid of his mischievous little dogs before they ruin the inn.

Recurring guest star LIZ TORRES plays Miss Patty, the local dance instructor and social commentator. Not appearing in this episode are series stars LIZA WEIL as Paris Geller and MATT CZUCHRY as Logan.
