Cate smugly reports that the test came back negative. She will not be taking the prednisone. House says the test was probably wrong, considering the conditions it was performed in, but Cate won't budge. Despite House's objections, Foreman says there's one more test they can try. He tells Cate to go outside and see if her kidney pain gets better. Cate's willing to do it, but House reminds her that she'll have to be outside for five minutes, and eight minutes outside in this weather would kill a healthy person. Cate's not exactly healthy. Cate says she'll take Sean the repairman with her. Or not, as she then passes out, taking the computer with her onto the floor where she lies with one eye half-open. That doesn't look good.
When we return from the break, Foreman says it took them twenty minutes to get in touch with Sean, and by then Cate was in a coma. They took advantage of it to shoot her up with prednisone, but it didn't do any good. So they're back to square one. House, Wilson, and Foreman are in an elevator on their way to find the "useful members of [House's] team." So...Chase? Good! I miss him. Wilson's only there so House can grill him on his new girlfriend. Wilson won't tell him her name, saying she doesn't have one. "Some sort of weird birth defect," he explains. So...Wilson's dating 13? I don't like it. House figures Wilson's reluctance to reveal her name means she must be someone House knows. He narrows down the list of suspects: Cuddy, one of Wilson's ex-wives, and "your momma," Wilson supplies. Ha!
On their way down the hall, House rules out Cuddy, since Wilson is straight and Cuddy is manly. You know, House, you can either talk about Cuddy's giant boobs and ass or you can say she's manly...probably not both, though. Back to Cate, they're stuck. They need to run a kidney function test on her but she's in a coma, so they can't. House thinks of a way they can get Sean involved.
"Drink her urine?" Sean says and I just realized why he looks so familiar: it's Matt from The O.C.! It's amazing I'd even remember him when he was so freaking bland on that show. He looks and acts much better here. Anyway, Sean has to drink Cate's urine and tell them if it tastes "concentrated" or watery. Sean's only question is how to get the urine out of Cate, which House finds surprising. Not me, though. I mean, what else is there to ask at this point? I'd want to do as little talking as possible and get it over with, myself. House thinks Sean must be in love with Cate to be so willing to do something so disgusting for her. Plus he'll get to see her naked, sort of. "Now I know that I can get you to do anything to save her," House says, his cold black heart breaking and scheming at the same time.
