Kumar, Foreman, and Taub catch up with Hadley at the elevator and immediately start in telling her they're sorry about her Huntington's and stuff. Hadley says she doesn't have Huntington's and House only said she did so they'd stop asking him about Wilson. Ah, nice deflection there, Hadley. Very nice. The guys aren't quite buying it, though.
The patient (her name ends up being Lou, although I never heard anyone call her that for the entire episode) is on the phone working hard when Hadley arrives wheeling a cart full of B12. Lou thinks she was just tired and dehydrated and there's nothing to worry about, because hallucinating an ant invasion and taking your clothes off in front of an office full of men in the middle of a sexual harassment meeting is as minor as a case of the sniffles. Hadley orders Lou to get back in bed for the B12 shot that we all know won't make her any better and will probably make her worse. Hadley injects her and says she's sure Marg will be okay without her for a few days. Lou says she wants to be there because her work with Marg makes her feel like she matters. "Yeah, I mean, without you who knows how much starch they put in her shirts," Hadley snaps. Wow, where did that come from? I guess when women get together, they can't help but be bitchy to each other! Heh, I only said that to piss Marg off. The joke's on Hadley, though, as Lou reacts to her insult by shitting the bed. Oh, wait -- the joke is back on Lou since that's not shit - it's blood. Blood coming out of someone's ass? House is officially back, y'all!
