Don visits his apartment to check on George’s beer, and continues developing his Bud diagram. He asks for Rosie’s input on the Lesbian Mothers Project. She says someone will try to claim infants without fathers are deprived, but he is more concerned that fathers seem irrelevant. She announces her flight to Melbourne, Australia, the next day.

Sonia invites Lydia to Don’s apartment because she thinks he is mistakenly disengaging from Rosie. George’s band practices, and Don shows them his father’s soundproof crib—which looks like a coffin. Sonia goes into labor, and Don suspects she is suffering from a prolapsed umbilical cord. Rosie enters and at his instruction, holds the baby’s head until paramedics arrive. George and his band, as well as George’s son the Prince, Gene, a reporter, and a photographer look on. Don does not accompany Sonia to the hospital, and Lydia, who still thinks Sonia is Rosie, says he lacks emotions.

Don formally introduces Rosie to Lydia, and explains his deception to both of them; Gene also learns the truth in the process. The reporter and photographer ask what happened, and Don shares his findings from the Lesbian Mothers Project.
