Back at the CSI ATV, Calleigh's back in her civvies, with a pants leg rolled up so she can put on her shoes and socks. Sevilla looks over and comments, "You picked up a few passengers." She has -- leeches. They writhe wetly on a stretch of skin. At this, Horatio falls to pieces and begins sobbing. Leeches killed his mother, you know. Whoops, there I go adding subtext and backstory to a character who's really just a crime-fighting machine. What really happens is that Horatio's all, "Yessss. A leech might leave its jaw behind. Let's use some good old-fashioned saline solution. May I?" Calleigh swoons as he sprays her leg with salt water. Horatio picks up Leech #1 and quips, "Bye." Calleigh laughs. He picks up Leech #2 and says, "Take care." Horatio has a chuckle, but before this can turn into a moment between him and Calleigh, he realizes that the salt in Barracks 2 might be related to leeches and the removal thereof.
Cut to Calleigh digging around a bucketful of leeches, telling anyone within earshot, "Can you believe these little piggies will engorge themselves to up to ten times their original size?" We get the TMICam shot of a leech doing so. Calleigh chortles to herself, "Leeches just fascinate me." Alexx cuts in with, "Leech saliva -- medical marvel, you know. It contains enzymes that expand your blood vessels." Calleigh cracks lamely, "Kind of like Viagra." Dear producers: I know you're trying to set her up as a convention-defying southern belle type, so that we're perpetually surprised and/or amused when this sweet-looking girl makes impish comments, but it's not working. Knock it off. Thank you, Sobell. Alexx merely laughs at Calleigh's comment and says, "Well, not quite. It contains a mild anesthetic so you don't feel the bite." Calleigh's been cutting open engorged leeches as they talk, and she coos, "Don't you hate it when that happens?" Alexx valiantly rises about the lame banter and exposits some more, "It also has plenty of hirudin, nature's own anti-coagulant." Calleigh comments, "My mother still doesn't believe me that they use leeches in modern microsurgery." Hey, direct her to www.leechesusa.com, which goes into interesting detail on how to use leeches for medical purposes and how to dispose of them afterward. Alexx comments, "Let her lose a finger -- she'll become a believer. Just slap this little mouth right on to any reattached limb and watch them do the housework, vacuuming up all that used blood so it doesn't cause gangrene. Which explains why there's no bruising on Dara Winters. The leeches removed the surface blood. The high level of anti-coagulant acted like a blood thinner so she never clotted. Those bites -- they bled for hours after the leeches finished feeding." Calleigh registers this without emotion. Or perhaps she's emotional, but we'll never know under the eight pounds of clown makeup she's required to wear at all times. She says, "It's the beer." Alexx asks, "What about the beer?" Calleigh explains, "The scent of beer is like catnip for leeches. When I was little, we used to pour beer on leeches and watch them whip into a feeding frenzy." Well, if you can't get to the spring break, bring the spring break to you, I suppose. Calleigh realizes that the beer accounts for why Dara had so many leeches on her body. Alexx replies, "At least she never felt it."
