Back in the classroom, Alex stops House's story to ask why he's talking about breaking into Dr. Hourani's office and finding sexy photos of his wife when they all thought House was Dr. Hourani. House has the entire commercial break to try to think of an explanation.
In the principal's office, House gets a call from Foreman. Hey, remember that patient? Well, he's still dying and the tests for sarcoidosis came back negative. The patient's only remaining lung is collapsing. House orders Foreman to start him on treatment for sarcoidosis anyway and hangs up. He turns to the kids and explains that sarcoidosis is a diagnosis of exclusion, which means that most of the time, it takes doctors a long time to get to it and by then the patient is usually dead or about to be. The kids don't care about that, of course. Zack wants to know why House lied about his last name while Colleen wants to know what House found in Cuddy's journal. I don't buy that ten-year-olds would really give a shit about any of this, but whatever. House says they've proven his point: not all cases are interesting, even if the patient is dying. Perhaps, but I'm much more curious about what's wrong with the patient than I am about any of the other stuff. Zack insists that House must have done something worse than use Cuddy's toothbrush or refuse to take out the garbage for her to be so mad at him, but House claims that's exactly what it was.
House is on Cuddy's doorstep, but she won't let him in. She says she needs "some time alone." House says it's "insane" of her to act like this because of a toothbrush and the garbage, but Cuddy says it's not just that, of course -- it's the fact that House does whatever he wants all the time and he's always right. House doesn't understand the problem. "Do you want me to be wrong?" he asks. Cuddy says she wants him to care about more than just what he wants and what he thinks. Well, if she wanted that, she shouldn't have dated House. This is Cuddy's fault, really. She says House may love her, but he doesn't care about her. "And I deserve someone who does," she concludes. Yeah, well, you were engaged to him like a year ago and you dumped him for House.
