Shania gathers Goldie and the guys for a big announcement. She's getting married! Well, pretend married; she's only nine after all. Wilbur, Shania's classmate, proposed to Shania with a candy ring pop, and she's completely smitten. Bryan is thrilled with Shania's announcement, while David finds it just downright silly.
Later, Bryan waxes poetic over the romance of Wilbur and Shania's impending fake nuptials. David isn't so romantic, as Bryan flashes back to David's thoughts on marriage early in their relationship. Sure gay men can have fabulous commitment ceremonies, but until it's sanctioned by the U.S. government, it's just playing house. Until every adult can get married in this country to whomever they choose, he refuses to get married himself.
It doesn't take long for Bryan to go into full wedding planner mode, even prepping a tasting platter of hors d'oeuvres for Shania and Goldie. David thinks this has gotten a bit out of hand: we're planning a full-blown ceremony now? It isn't even real! Soon enough Nana arrives to put a damper on the mood. She thinks this charade is ridiculous and makes a mockery of the institution of marriage. In her eyes, marriage isn't for children, or for gay men for that matter.
Shania's big day is finally here! Goldie made Shania a beautiful wedding dress out of autumn leaves at Shania's request, and even Bryan admits that Goldie did a wonderful job. Meanwhile, Wilbur's sweating bullets as David gets him all suited up. David reminds him that he has no need to stress out; this wedding isn't even real, and as such, it means nothing. Bryan overhears and is crushed by David's harsh words.
Between a recital of lyrics from Shania's favorite "poet" Nicki Minaj and Shania's truly heartfelt vows, the ceremony is equal parts ridiculous and moving. But things come crashing down when a troupe of conservative nine-year-olds (recruited by Nana) out Wilbur and his womanizing ways and destroy the wedding. Shania runs out, devastated.
Bryan takes the loss even harder than Shania, opting to eat his feelings. His spirit broken, Bryan claims that David was right; the wedding was a dumb idea. Meanwhile, Goldie tells Nana that she's had enough; ruining Shania's wedding was a heartless and devastating move. It's time for Nana to get out of their lives and go back to Ohio.
Later, Bryan drowns his emotional devastation in an episode of "Say Yes to the Dress." David drags him away promising him Chinese food, but really he tricks him into going to his office. In the procedure room, which is filled with candles, Goldie is there with the baby's heartbeat up on the screen. David gets down on one knee and proposes to Bryan, telling him that he wanted their baby to be there for this moment. When David saw Bryan's true tears during Shania's fake wedding, he realized how real and important marriage is to Bryan, and also to him. Bryan, of course, accepts!
