Cameron asks Carnell about any prior recreational drug use. Carnell doesn't want to answer with his dad in the room, but Dad assures him that, at this point, Carnell's drug use is the least of his worries. Carnell admits that he tried ecstasy "at Christmas," which is either almost a year ago or just happened, judging by those Christmas decorations we saw before. Or maybe whoever owns that building loves Christmas so much that he leaves those decorations up year-round. It would explain why Carnell and all his friends are graduating in the middle of the school year. Before Carnell can elaborate on how amazing his dorm carpeting felt while he was rolling, he is shocked again.
Foreman's latest test shows that Carnell doesn't have lupus, which they already knew. Chase thinks Foreman should be concentrating on getting new information about their patient like House told them to, not doing the same tests over again. Meanwhile, Chase appears to be doing nothing but watching Foreman work, so...whatever, Chase. You could at least be spending this free time getting a haircut. Cameron walks up and says she got a more detailed family history that didn't show anything significant about Carnell's medical condition, although she did find out that Carnell's maternal grandfather served in an "all-black tank battalion under Patton." "Fascinating" is Foreman's sarcastic response, but I'm guessing he's just mad that House is giving them riddles to solve instead of a way to treat their dying patient, because that stuff about the tank battalion under Patton is pretty awesome. I want to know more, but this is a medical show on Fox, not a military history show on the History Channel, despite R. Lee Ermey's appearance later on (spoiler!). Foreman still thinks they're dealing with MS, despite the fact that the MRI ruled it out (since as we all know, MRIs are totally useless. And dangerous). Foreman explains the low white count by saying that Carnell is an alcoholic, as evidenced by the 2.0 blood alcohol content he was sporting when he was admitted to the ER. Cameron protests that Carnell was just doing some pre-graduation partying, not like she'd know anything about that, since I'm guessing Cameron's college experience involved absolutely nothing illicit or fun whatsoever.
