Anyway, Foreman decides to be a doctor again and tells House to stop wasting time talking about a dog and start testing Matty for everything they can. House says that their patient isn't sick enough yet for them to be able to do that; he doesn't have enough germs to show up on the tests, and he isn't sick enough for them to get an idea of what's wrong with him so they can figure out which tests to do. House figures that their only choice if they want to figure out what's wrong with and cure Matty in time to save his brother is to make him sicker. Well, I am impressed -- it usually takes this show a good thirty minutes before we hit the "make you sicker to make you better" mark, but this time it's only been like five minutes. Foreman doesn't think intentionally making a child sick is a good idea, and would rather check Matty's house for "sources of infection," which he says is a "safer choice." Not if he gets caught breaking into Matty's house, it isn't! But Foreman's all about safety now that it's too late for Lupe. Much to Cameron and Chase's apparent surprise, House grants Foreman's wish to check the house.
