Leaving

S1, E12: Already being hounded by Janet for money to replace her air conditioner, Tommy gets a stern warning from Jerry to steer clear of Sheila. And as Jerry complains about a bookie who's forgotten to pay off a big bet, and Franco returns to work with his daughter, Keela, in tow, a trio of rowdy firefighters from Massachusetts ask to stay at the firehouse while they construct a 9/11 memorial. Asking them to keep a low profile, Sean leaves them at the station while he's at a fire where he apologizes to Laura for all the harassment. Meanwhile, after an uncomfortable phone call from Sheila, Tommy learns that Janet is lying about the air conditioner. And when Mike suggests that they consider living together, he's surprised to learn that Theresa is bulimic. Ordered to get his daughter out of the firehouse, when Franco asks his girlfriend, China, for help, she balks, telling him that he'll have to choose between her and Keela. Though surprised when he is paid off for a bet he never made, Jerry has second thoughts about returning it when he learns that his longtime bookie has Alzheimer's. After his dinner invitation to Laura is rebuffed, Sean is startled when he spots Mike and the overweight Theresa. And after Laura complains about how everyone is talking about Theresa behind Mike's back, Sean raises suspicions when he asks that Lou stop harassing the new female firefighter. Meanwhile, when confronted about her lies, Janet tells Tommy that she needs the money for household expenses. As Tommy's recklessness continues to call his judgment into question, the memorial built by Sean's friends sets the firehouse ablaze. While a visit to the firehouse that ignites rumors about an affair forces Tommy to order Sheila to leave and promise to see her later, Sean is delighted when Laura asks him to dinner. Then, as a misunderstanding accidentally reveals that Laura and Sean are sexually involved, a call for help from another firehouse leads Jerry to realize that his wife is starting to exhibit symptoms of Alzheimer's. And after Arlo comes through with the money for Janet, Tommy learns that his dad has left for Ireland. Finally, as Theresa and Mike's relationship starts to crumble, China makes good on her threat to walk out on Franco. And as Janet stashes the money with the rest of the cash she's hoarding, Tommy arrives for his showdown with Sheila.
