Booth busts open Bro's door and tells Brennan that if anyone asks, the door was open. So much illegal police activity on this show. Booth walks through the apartment, calling for Bro, and clears each room, gun drawn. He declares the apartment clear and Brennan calls Jack to report all the chemicals sitting on the kitchen table. Jack confirms that they are bomb-making materials. Booth finds a wall torn away where Bro was getting the insulation. Booth thinks that Musrak discovered Bro's activities, and that's when they were both exposed to the poison. So helpful of Bro to leave all his clues sitting out in the open like that! But wait! There's more! Booth finds a mechanic's guide to Musrak's SUV with the page about odometers dog-eared. No, I'm not making that up. He really found that. For crying out loud. I wish that were the end of it. Brennan finds Bro's prayer rug and extremist materials! He wasn't a Christian! Booth finds something that convinces him that Bro has made another bomb, and is out in the world with it right now. Brennan asks Jack what the dispersal rate is for two liters of dioxin. Jack says it's three to five hundred meters, and it would be horrible for anyone exposed. If only Bro had left one more clue about what he was planning! Oh, but wait! Booth finds a day planner with that day marked.

As Booth and Brennan speed away in the SUV, Booth is on the phone with the FBI, reporting that the store owner across the street saw Bro get on a bus and head downtown. Brennan is on the phone with Angela, also trying to figure out bus schedules. Booth says that 5:30 PM was circled in the date book. Brennan reports that to Angela, who does an online search and…what a break! Man, it only takes one break to make a case. Or in this instance, like five million breaks. Angela finds that there is a peace conference at the Hamilton Conference Center with speeches by Arab moderates and a senator. Booth and Brennan banter about how ridiculous it is to blow people up to bring about peace, like, thanks for the anti-terrorism lecture. Booth tells the FBI what they know, and calls for backup, but warns them not to spook Bro, or he'll blow himself up. Booth once again tries to convince Brennan to let him handle it, and predictably, Brennan's not having it.
