Horatio checks her stomach bruises, but before he can get a better look, Amy expresses the fear that this will show up on her permanent record. Horatio assures her that her parents won't find out what happened. We find out that the marks on her stomach are from body shots; then we flash back to Amy as the living bar, lest any instance of salacious footage be forever lost to the episode. Horatio wonders if she knew any of the men who were slurping off her stomach, and Amy rolls her eyes as she explains how the whole purpose of spring break is to meet new people. Look how well that's turned out for her. Horatio manages to get Amy to show him the bite marks with, "Amy, listen to me. I know this is difficult, but you see, teeth marks are like a fingerprint and it could really help me go after this guy, you understand?" Amy shows him the bite marks on her thighs, and begins sobbing about how MTV's spring break bacchanalias never feature the biting guys. Horatio pulls the Grief Whispering act on her and reassures her about how she's safe. Boy, he really goes for the damsels in distress, doesn't he?
Meanwhile, back at the party, Ted the marketing weasel is busy spraying people with Madraca Tequila and bellowing about its party-friendly qualities. Speedle is well away from the party, processing another crime scene, when Horatio comes over. They discuss Amy a little bit, and then Speedle asks if Horatio got anything off her bites. Horatio tells him, "No. You know how bruises are." Speedle recites, "Blood rushes to the bites, swallows them, diffuses them, you can't get a match." Horatio adds angrily, "We're back to square one." Better not let Amy hear you say that. Speedle begs to differ; he holds in his hands a memory stick commonly found in video cameras. The two quickly conclude that the attacker could be on the camera.
B-plot time. Delko wanders into the lab area where Calleigh's working and tells her that according to the DNA-lab people, all four boys were sucking on that bong. Calleigh asks about the white specks in the bong chamber, and Delko tells her it was phlegm plus ACL. Calleigh's all, "Stomach acid. Who threw up?" Oh, who do you think? It was Trey. Calleigh figures the vomiting is a symptom of his aneurysm; Delko counters that the aneurysm could have been the result of a trauma. Calleigh asks, "You up for a dog-and-pony show?" Is Delko ever! He loves the circus.
