Joan ducks into a room and looks in Adam's bag. She pulls out a bunch of wires or something, bent into a V-shape. Mystified, she puts them back, and then goes up a flight of stairs. Through the window on the landing, she sees the street cleaner and races outside.
Daghlian has reports indicating that the arsonist employed a sophisticated device involving magnesium accelerant. He concludes that they're looking for a pro. Will says, "Well, magnesium is a type that outdoorsy people get from outdoorsy stores to start fires in outdoorsy places." He calls Daghlian's attention to the list of people who'd recently purchased it. Daghlian notices Tom Wyatt's name on the list, and comments that he's not the outdoorsy type. Will shows Daghlian (can we get a first name on the guy? Wait, I just looked it up on IMDb and it's Michael) a list of shareholders for a development company called Badger Hill. Apparently that company owns most of the property around the arson site. Daghlian, looking at the list: "Wyatt again. Did he really think we wouldn't get here?" Will thinks maybe he didn't care. He tells Michael about the party he was at the night before, where most of the guests seemed to have something to do with Badger Hill. Reading the list of shareholders, Michael says they're the people that run things: "They're way higher than I am on the food chain." Will: "We arrest people. We're the top of the food chain." Michael manages to say that he'll do whatever Will wants, but...Will: "Only if I specifically order you to do so? Maybe you want it in writing to fully cover your ass?" Michael: "It's the real world, Chief. I gotta live here."
