Realizing that he has had sex with Quagmire's transsexual father, Brian vomits profusely for thirty uninterrupted seconds, and then he and Stewie begin panicking. After Stewie fills him in on the events that transpired in his absence, telling him that Quagmire's newly gender reassigned father has been staying at the same hotel as Brian, Brian is amused until Stewie informs him that Dan Quagmire's new name is Ida. Peter and Lois go into hysterics, while Brian, still both angry at them for earlier and not aware yet of the whole story, dismisses them as jealous. The next morning, Brian shares his newfound love with Peter and Lois before showing them a picture of Ida on his cell phone. Quickly bonding, they retire to Ida's room for sex. On his way home, Brian stops at the Marriott, meets Ida and has a few drinks with her, unaware of her previous identity. Brian gets angry that they would care that little if he did really leave forever, but Peter says that they always assume he's going to someday leave and go off to die in the woods, and Lois dismissively tells him that he's not really a member of the family and the "Griffin" surname is applied to him as a courtesy it is not legally binding.
Meanwhile, Brian is stunned when he bids the family "goodbye" so he can attend a class on creating a web series and both Peter and Lois react as if he's telling them he's leaving forever – something they are indifferent about. Saddened, Ida leaves Quagmire's home and decides to stay at a nearby Marriott Hotel. At Quagmire's home, Quagmire tells Ida that he is not sure he can deal with her new gender identity. As the dinner begins, however, Quagmire becomes frustrated when the Griffins turn the conversation towards Ida's operation, and storms out of the room.
That night, Ida and Quagmire join the Griffins for dinner. The surgery is a success, with Quagmire's dad emerging as "Ida". Concerned that his dad might actually be gay, Quagmire confronts him and Dan states that he is not gay, but is instead " a woman trapped in a man's body" and that he plans to have a sex change operation during his stay in Quahog, much to Quagmire's dismay. At the ball that night, members of the Navy bombard Quagmire with compliments about his war-hero father, most of which can be taken as double entendres about Dan's alleged homosexuality. The following morning, Quagmire invites Peter and Lois to the Naval Ball being held to honor his father, but soon begins arguing with Peter about his father's sexuality. Expecting to see the inspiration for Quagmire's sexual behavior, they are surprised by Dan's stereotypically gay mannerisms. Peter and Joe visit Quagmire and are introduced to his father, Lieutenant Commander Dan Quagmire.
