Although we are not privy to the conversation, the presence of a composed Cawdrey in the interrogation room seems to imply that the blood on his pants came back matching Dara's blood. Either that, or Horatio's going to quiz him on the Seven Ancient Wonders of the World and make him give an oral history of the Pharos Lighthouse, completed around 270 B.C., and, presumably, the symbolic origin of the detention camp's name. Then Horatio asks, "The blood on your camouflage pants matches that of a fifteen-year-old girl you've never seen. Can you explain that?" Cawdrey says, "I already told you -- I never laid eyes on this girl before in my life." Horatio says, "Right," in such a smug, disbelieving way, I want to smack him. They go back and forth, Horatio arguing that surely he knows how the blood got on his zipper and Cawdrey saying he doesn't. He continues, "I'm very sorry for this girl and her family, but if she was in my camp, then she was trespassing." Horatio concedes the point, then adds, "Why don't we discuss the ride that night?" Cawdrey replies, "You've got it all wrong. Last time I rode that ATV was yesterday morning. I ran it out to the chapel, then to the latrine, then back to admin. Whatever you guys are thinking, I didn't touch any of these girls. I'll take a lie-detector test, whatever you want." We see a shot of Horatio looking skeptically down his nose. He is such an ass -- they're treating this guy like he's got a lock of Dara's hair dangling from his belt, and when the evidence proves he's not involved, will there be a scene where Horatio is apologizing for his approach and explaining that he's got to treat all suspects with skepticism? No, there will not. As for right now, Cawdrey willingly gives prints and a nasal swab.
