Warrick is at the bus company garage, talking to Maddox. Maddox is pointing out that the company had a perfect safety record. "Until last night," Warrick replies. Maddox rebuts that in any transit business, accidents are inevitable. He does not add, "But, I assure you, we do everything possible to reduce their statistical probability." Anyway, Maddox is all, "Accidents are inevitable," and Gil pops into the frame to say, "Criminal acts, however, are not." This immediately puts Maddox on the defensive: "I've got a family. Sometimes they ride my buses. I don't take a chance with their lives or anybody else's. I screen all my drivers, zero tolerance for drugs or alcohol, I keep strict maintenance records, vehicle inspection every forty-five days as required by law. You're not going to find anything criminal here." Gil begs to differ, handing over the sheared bolt and drawling, "I believe this belong to you." Maddox inspects it, saying, "Bolt, grade eight, sheared. That doesn't happen." Gil contradicts him yet again. Warrick steps in and says they have many questions, all of which spring from observing that the suspension didn't hold. His Small Businessman's Righteous Wrath undercut by the implacable stares of Gil and Warrick, Maddox says that he buys all his parts from reputable vendors. Gil and Warrick aren't interested in all the parts -- just the ones that broke, i.e. the bolts. Maddox supplies, "Brillway Bolt Company. I just switched...they were low bid." His face falls as he realizes how his decision affected the bus accident. Warrick piles on the guilt with, "The consequences of saving a buck." This is like the anti-10-10-220 commercial. Maddox grounds the fleet, presumably to remove all the faulty bolts.

Meanwhile, Sara is suffering her own private hell as she matches up umpty-jillion shredded pieces of rubber against the bus and Camaro tires. At least she has some pleasant background music to keep her company as she does so. The music keeps playing as Brass questions people at the rest station in Barstow. A gas-station attendant reports that Marty Draper was a regular; a female attendant points out that she was being ogled by someone who bought a lot of turkey jerky. She also noted a fight between a couple. Brass then talks to a mechanic (note: he's the only one wearing a nametag. It reads "Sean") who can recite the particulars of the bus route. Sean did not notice the couple fighting. The background music kicks up again as Sara continues to work with the rubber tire fragments, swabbing the pieces that match for chemical residue.
