Mitchell (Jesse Tyler Ferguson) and Cameron (Eric Stonestreet) organize a baby shower for Sal (Elizabeth Banks) with Pepper (Nathan Lane) and Ronaldo's (Christian Barrillas) help. However, they are surprised when they discover that Sal is now a teetotaler who actually cares about her son, Sammy. Though they enjoy it at first, Sal leaves the baby shower leaving Sammy behind and the two couples believe that Sal abandoned her son. Mitchell and Cameron start arguing with Pepper and Ronaldo over Sammy since both couples want to adopt him. Sal finally returns to let them know that she would never abandon her son and informs them that she went to see Sammy's dad who is actually a hockey player and was unaware of Sammy's existence.

Claire (Julie Bowen) reluctantly agrees to attend Phil's (Ty Burrell) cheerleader friends reunion during a weekend. On their flight home, she takes the only first class seat while Phil lands in economy class. Things take an unexpected turn as Claire realizes that Dana (Natasha Leggero), the woman she is sitting with is actually a loud and obnoxious bigot, while Phil enjoys his time with a magician (Penn Jillette) and a masseuse. Claire asks Phil to switch seats but Phil avoids it by lying that he is having a terrible time himself with the people who sit next to him. Claire discovers the truth and the two of them end up fighting with Claire confessing how terrible was the weekend for her and the sacrifice she made for Phil. After Claire's confession, Phil accepts to switch his seat and let Claire have some peace and quiet.
