House limps over to the coffee machine, because nothing goes with saliva-borne pathogens better than java. Foreman asks him what is so interesting about this case. House says that, right now, it's how much Foreman doesn't want to work on it. This, by the way, is the same logic Cuddy must be using when she forces House to do his clinic hours. Ah well, House never did strike me as someone who holds much stock in the Golden Rule.
The lesion-scarred hand of Jane Doe draws a cartoon of two people in front of a building. Chase says that is a nice drawing of Foreman, like just because Foreman and the cartoon are black doesn't mean they're the same person. The Foreman cartoon is enquiring as to James's whereabouts. Chase asks who James is, and Jane grabs her head and starts freaking out, tossing her food tray into the camera. Well, there goes Foreman's theory about homeless people faking sick to get food. Chase runs off to get some drugs, while Foreman tries to hold Jane down. She bites his wrist, which is just silly because now she's going to have to go back and change her drawing of him to show bite marks. Why make more work for yourself? Chase says Jane is negative for HIV and hepatitis C, so there's some good news. That also explains why House didn't hesitate to eat her puke. Pisssed-off Foreman says he's getting a tetanus shot and Jane is getting her MRI so that they can kick her ass out of the hospital.
