House finds Cameron down in the ER, working on her day off. He wants to know why she's still at PPTH. If she wants to monitor Doug, she can do that just as easily from home as she can at work. "You're not at my home," Cameron says teasingly. Actually, House says, it's more like Chase is at her home. Except that he's actually at PPTH now, since House called him in to do the surgery. "You and Chase are over," House says. Cameron wants to dump Chase and is using House to do it. The smirk leaves Cameron's face, and she says that Chase is going to propose on their vacation. She found the ring while she was packing. It's not that she doesn't want to marry him; she doesn't want him to ask right now. So avoiding the vacation entirely makes things a lot easier. For Cameron. She thinks she just doesn't want him to ask right now, because it'd be a fear reaction to Kumar's death rather than a genuine desire. I guess the second time around, Cameron wants to make sure she getting married for all the right reasons. Meanwhile, House was not expecting all this emotional stuff and doesn't know what to do or say. He goes with "oh" and leaves.
Quick, House! To the emotional bankruptcy of Clinic duty! A husband and wife are there, and while the wife's the one with the fatigue and sore breasts, the husband's the one who won't give her a chance to say anything. House instadiagnoses her with a hot tub-related problem, but the husband denies that his wife has had any exposure to a hot tub. House tries to give the wife a chance to say she used a hot tub during a business trip, but she speaks up for the first time to deny that as well. Cuddy walks right on into the exam room to talk to House, and he's happy for the chance to think of more ways to give the wife an excuse for how she was in a hot tub without her husband but not having an affair. He says this out loud, but it still manages to go over the wife's head. Cuddy's big important question that she had to compromise a patient exam to ask? "What's going on with Cameron?" As soon as House says Cameron doesn't want to sleep with him, Cuddy is satisfied, and House notes that Cuddy didn't really want to know what was up with Cameron -- just that whatever it is has nothing to do with House. Cuddy's busted. The husband loses his patience and asks how this is a medical crisis more important than whatever's going on with his wife. "A lot of STDs hang in the balance!" House says. But he'll pay for turning around to make that clever quip, as when he turns back to Cuddy, she's gone. As for the wife, she'll need vinegar compresses four times a day on her breasts for the skin infection she picked up in the hot tub she used without her husband. I think the wife's "I'm busted!" face is actually better than Cuddy's.
