M3, T13: The days following his brother's funeral and his sister's wedding find Tommy wrestling with his promises to care for Janet and their kids now that Johnny is dead, and to retire to the beachfront home Sheila has bought for them to start life anew. As Jerry's stroke leads to the appointment of a temporary replacement, Franco enlists Natalie's brother to help him prepare for the lieutenant's exam and Mike considers a ménage a trois with a brother and sister. And as Maggie and Sean are caught having sex on the new chief's desk, Lou tricks Tommy into having dinner with Theresa, the nun whom he is planning to live with on board his cousin's fishing boat. As Tommy soon discovers, the difficulty keeping his promise to care for their kids pales in comparison to what he and Janet are up against when they have to come up with an explanation for her pregnancy. In the wake of his date with Sara and Greg, Mike reconsiders any thoughts of his suspected bisexuality, and things suddenly become even more complicated when Jerry escapes from the hospital and shows up at work. Meanwhile, as failing to complete the lieutenant's exam leads Franco to realize that he isn't really prepared to care for his daughter, a visit to the fishing boat with Theresa convinces Lou that he isn't cut out for life on the water. Though he hasn't said anything about it at work, Tommy goes to file his retirement papers but balks before he's done. Meeting face-to-face to tell Keela that she is better off living with Alicia, Franco learns that she's being sent to a boarding school in Europe. Finally, as Lou tells Theresa that he cannot live on a boat, and Maggie insists on having sex at the firehouse, Tommy's friends change their minds about leaving 62 Truck. And once Tommy reveals that he has to take care of Janet and the kids, an angry Sheila drugs him into unconsciousness during their first beach house dinner and then leaves in a panic after accidentally starting a fire.
