Michael returns from Paris as if he's joined a higher income bracket with all the things David has bought him: new car, expensive clothes, and no time for Brian and the others. The harassment at school continues for Justin, but his request for a gay-straight student alliance is still denied. Lindsay continues ahead with her plan to marry Guillaume despite Brian's warning she's marrying the wrong person. Guillaume counters Brian's threat to call Immigration by reminding him that Lindsay could go to jail over their green-card marriage, then pushes Brian's buttons by suggesting that he might adopt Gus to make their arrangement look more convincing. Debbie and the others discover that Michael and David are hosting a black-tie political fund-raiser for State Senator Diane Baxter, but Michael makes it clear they are not invited. Brian, Justin, Emmett, Ted, Debbie and Vic crash the party anyway, with Ted dressed as a biker, Emmett dressed as Jackie Kennedy and everyone else dressed for Babylon. They turn the conservative fund-raiser into a party, Debbie and Diane bond, and everyone is having a great time. Except for Michael, who is horrified and embarrassed by his mother and friends for "ruining" the evening. He demands they leave, in turn making Debbie ashamed of him. Brian stops the wedding by agreeing to sign his parental rights to Gus over to Melanie, on the condition that she and Lindsay reconcile. They make up and Guillaume is sent packing. Justin and Daphne win with the help of Debbie, some protesters, and the media attention Diane brings. Debbie forgives Michael when he comes by the house and apologizes to everyone for his behavior at the party.
