Sofia stomps around to the back of the van. I have no personal objection to either the character or the actress, but I cannot fathom why Louise Lombard elects to have Sofia lurch around like she's on a pair of rented shins. After she hops into the back of the van, Warrick regains the power of speech, asking Emergency Backup David, "You see that blood spot on the lapel? It's inconsistent with the head wound. To avoid cross-contamination, do you think you could cut it out for me?" Emergency Backup David sure can. He's so agreeable. Sofia lurks in the back of the van, possibly preparing to scare the bejeesus out of Warrick from a different angle. Actually, she's telling us all about the possible GSR on the back of the driver's chair, which indicates that the shots were fired from the wheelchair. Warrick's all, "How'd he shoot him in the face?" Sofia calls, "Hey, Vinnie," and when the little flashbacked guy turns around, she makes the appropriate sound effects while pointing her index finger. Unlike the rest of us, however, her finger is lethal. It wings Vinnie in the head and blows a hole in the windshield. Warrick's still skeptical: "We got a guy that fired a shot from the wheelchair, then escaped on foot." Sofia looks thoughtful.
