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 and apologizes to Laura for the harassment. Mike is in for a surprise when he suggests that he and Theresa move in together.
