Wilson tells Sgt. John that the antibiotics they're giving him should make that vaginosis go away soon. You'd think that, but I'm going to tell you right now that Sgt. John will have crusty white stuff around his mouth for the rest of the episode, so you can prepare yourself for that nastiness. With that, Wilson starts the biopsy process while Sgt. John whines that he was one of the only guys in his unit who didn't chew tobacco, and now he's the one who has mouth cancer. Wilson says that this kind of cancer is "very treatable if caught early." Sgt. John is pretty sure that this isn't early, seeing as he's spitting smelly white goo out of his mouth.
The Cottages are actually following House's orders and trying to get Sgt. John's dating history. Well, actually, they're wondering why House is making them do it. Cameron thought he was wasting their time with Sgt. John's personal background info to get back at Cuddy for making them take this waste of time case, but since Sgt. John clearly has a real problem, that can't be the case anymore. Who cares, Cameron? Just do it. Investigating some guy's private life has got to be kind of fun. Foreman's doing some investigating on his own, and asks Cameron and Chase where they were when Sgt. John woke up. Cameron plays it cool, while Chase stammers that they went to get coffee. Foreman asks why they didn't have any coffee when they came back to the room, then, like, maybe they drank it already. But Cameron says that's because they didn't actually get coffee; they had hot sex in an empty bedroom. Foreman laughs: "House would do Wilson before you'd do Chase," as if House and Wilson having sex is an unlikely event. "No, you would do House and Wilson before I'd do Chase," Cameron counters. And seven thousands fanfics are begun. Chase gets all offended that Foreman doesn't believe Cameron would ever have sex with him, pointing out, "She did me once!" "She was stoned!" says Foreman. And Cameron smiles like she's proud of this.
