Suddenly Gorillaz blare on the soundtrack. Yikes. What is contemporary pop music doing on this show? That's disorienting. Various upper-class twenty-somethings are grooving to the beat at a party. A guy named Dylan is informed that his cousin has arrived. Upon learning that the cousin in question is named Billy, Dylan says, "That's not possible," and then turns around to see Billy. Finally, someone let him out of his cage. And we've certainly seen destruction and demise, corruption in disguise. So yeah: we get it. Billy looks around, spies a couple smooching on the couch, and says, "Somebody should talk to them about appropriate public behavior." Dylan looks worried.
Happy little blood cells frolic about, unaware that Wesley is looming over them, using a microscope to spy on their innocent antics. He invites Fred to take a look, and she says it looks as if "some of the red blood cells are kinda supercharged." They're carrying more oxygen than usual? Wesley guesses that's the result of Billy's "demon lineage." If Billy's part demon, then presumably so is Congressman Blim. Or the Congressman's in-laws are. They conclude that Billy's power stems from his blood. Sure. This is just a suggestion, but I think it would be best if the writers kept far, far away from any pseudoscience. Just say, "Billy is magic. And so is his blood!" Implying that Billy's "supercharged" blood has filled him so much hatred that it's literally oozing out of his pores is profoundly dopey. Fred adds, "It could also be in his sweat or his saliva, or even his touch." Wesley looks up and gets the best non sequitur ever as he asks, "Speaking of saliva, where is Cordelia?" Fred tries to follow that train of logic, but Wesley curtly repeats his question. Fred nervously says that she thinks Cordy went out. Wesley asks where, and Fred replies, "She said an errand." Wesley triumphantly observes that if Fred spoke to Cordy, than Fred knows that Cordy went out. Fred admits that Wesley's right, and he leans back over the microscope before saying, "Lie to me again and we're going to have a problem." Let's use this commercial break to try and figure out why Wesley's being such a jerk. More than usual, even.
