Chief sits in his den, watching the game. Pete walks in and reports on Jeannie's actions of the day. As soon as Pete sits down, Chief says he's tired, and that he's going to bed. Pete sits there alone.
Tommy and Lou discuss Lou's weird bone marrow recipient. Lou points out that donating bone marrow isn't exactly pleasant, because it involves "getting wheeled into surgery and having a spigot shoved into [your] spine like a goddamn maple tree at the height of sap season." Tommy can't believe the guy didn't thank Lou at all, and Lou says he's tempted to find out the guy's name and go tell him off. Tommy gets back to his favorite subject, himself, and asks if he can crash at Lou's place for a few nights. He adds that Colleen is staying with Pa Gavin, but Tommy isn't interested in staying at the House of A Thousand Cats. Lou says that he sold his house and has been secretly staying at the firehouse. He tells Tommy that there's plenty of room, with one caveat: "I don't spoon." Tommy asks, "Since when?"
Sheila grabs some snacks out of a cupboard in her house, and that woman has the most well-stocked snack cabinet I've ever seen. It's packed to the gills with food. She walks into another room, and once she's gone, Tommy sneaks in the back door and into the kitchen. He finds a bill or statement or something with Sheila's doctor's name on it. Sheila hears him and calls out, thinking it's Damien. She walks back into the kitchen, still eating, but Tommy isn't there. Once she walks out again, Tommy runs out of the cupboard where he was hiding and exits quickly out the back door.
Tommy shows up at Sheila's doctor's office and tells the receptionist that he's with Sheila Keefe. The receptionist thinks he's Mr. Keefe, and Tommy doesn't correct her. The receptionist says she will let the doctor, Dr. Feinberg, know that Tommy is there.
Chief approaches Garrity in the locker room and asks to talk. Garrity says that if it's about Heather and her prior dating history, he's already heard it and he's not interested in rehashing it. Chief says it's slightly different. Grinch read the report on Heather's fire, and realized that it's the third friend's apartment Heather was staying in when it caught fire. Chief adds that, in two fires, candles got too close to some curtains, and in one, the fire started with newspaper in a bathtub. Chief asks if Garrity gets the message. Garrity, of course, doesn't. Chief says that Heather is a firebug, and that she probably starts fires to meet firefighters. Garrity gets all fired up (no pun intended), and Chief points out that no fire starts in an empty bathtub unless someone lights it, and orders Garrity to get rid of her. Garrity just hangs his head.
