The Cottages are back to differential-diagnosing now they have some more symptoms to work with. They think Fletch either has a neurological infection or an autoimmune disease, because Foreman and Cameron specialize in those fields respectively and are always ready, willing, and able to assume that their patients are suffering from them no matter what their symptoms actually are. Chase just sulks. The phone rings. It's House, wondering how high Fletch's fever is and why the Cottages haven't called him about it yet. He orders them to treat Fletch for a possible meningitis or encephalitis infection, and to do an MRI on Fletch that they should've lied, cheated, and stolen to get done earlier, as Chase is happy to report to House that Foreman had trouble getting the use of the machine the right way. You know -- the way that doesn't endanger the lives of whatever patients are waiting for the machine before Fletch, and who therefore presumably have a more urgent need for it. House is very disappointed in their honesty as he pulls the boy's rubber ball out of his coat pocket, where he's managed to conceal it after stealing it from him. The boy looks for his ball futilely. Stealing from children is wrong, but maybe not so wrong when the child is such a brat. And it's still not as wrong as kissing children, Chase. He tells them to get a proper medical history from Fletch, despite the obvious difficulties, and says that his flight should be in in a few hours. As soon as House is gone, Cameron snarks that Foreman doesn't seem like he's all that in charge of House after all. I guess she's given up on the diplomatic approach.

Chase tries to get Fletch's medical history by asking him yes or no questions. He narrows down Fletch's last visit out of the country to between two and three years ago.

Cameron sits down with Wifey, who tells her that Fletch hasn't been out of the country since he settled down with her, and that his last vacation was a golfing trip with some friends.
