So she runs off to find out who that someone else is, Delko at her heels. They're back at the packed hotel -- one wonders if Delko's underage groupies were swooning by the pool as he walked by -- and at the room to which Trey was registered. The cops knock, and the jackball who answers is all, "What took you so long? The ad said half an hour." I hope to God they weren't ordering some sort of coed stripper service. Delko makes the introductions, and that gains them entree; Jackball apologizes and explains that he thought they were pizza delivery. The hotel room is pretty unimpressive-looking, and the open-mouthed miscreants splitting their time between playing a computer game and pummeling each other don't help the ambiance any. They do, however, explain how Trey had so many bruises. Delko says that they're there to ask about their roomie, and Jackball quickly says, "Trey? He's not here." God, could he be any more insultingly obvious? Calleigh notices two things: how neat the room is, and how truly moronic Trey's friends are. Jackball tries to throw everyone off the scent with, "I think Trey might have hooked up with that blonde girl from IU," but the blonde woman in the room ain't even listening. Delko pretends to be paying attention. Calleigh then asks for the clothes they were wearing last night. She gets no response. Delko turns off the TV and says, "Your friend is dead. What we need are the clothes you had on the last time you were with him." All three dullards gape at Delko. The cop snaps, "Let's go!" The boys get up and begin searching for their clothes. Delko takes a call from the tox lab; Trey's THC levels were 200 nanograms per milliliter. Calleigh's impressed: "Whoa. That is out of control. Did you guys smoke marijuana with Trey last night?" All three guys claim they didn't. Calleigh boots them so she can search the room for controlled substances. Delko quickly finds a bong hidden in the sofa's box springs, and Calleigh finds the pot in a baggie stowed in the toilet tank.
