Instead of trying to diagnose his patient, Foreman is venting to Chase and Cameron in the cafeteria. Cameron says she's not surprised that House is refusing to help. Foreman pushed him by taking a secret case, so now he's pushing right back. Foreman decides to actually give his case a try and asks what he's missing. Chase says the mother could be poisoning her son for attention. Foreman thinks Evan would have noticed something if that was the case. Yes, because most eight-year-olds are keenly observant of their mothers to make sure they aren't trying to kill their younger sibling. Please. Chase suspects the brother, then. I do, too! He's a little too concerned and cares too much. Foreman doesn't think so, saying Evan isn't jealous of his little brother. In fact, he looks out for him all the time. And that gives Foreman an idea. He takes off. "Think we gave him an idea?" Chase asks. "Either that or he's off to kill House," Cameron says. She's always got House on the brain, doesn't she?
Hadley finds herself at the door of an apartment next to a generic liquor store, courtesy of the Fox backlot. I do love the signs on the window of the store, especially the one that just says "LOTTERY!" A man answers the door, and Hadley introduces herself as the doctor who's treating his daughter for leukemia. She says they need him and his wife to give a sample for a bone marrow transplant. The man is confused. A girl walks up behind him holding a bowl of popcorn. Ew. Sophia's rape-o dad got another girl. Or not. "This doctor says you have leukemia," Dad says to her. "I don't have leukemia!" the girl says, as if leukemia was cooties. I think I'd be more alarmed if a doctor came to my door saying I had leukemia than disgusted. Hadley asks if she's talking to Sophia Isabel Velez. The girl says that's her name. "Do you know something I don't?" she asks. "Just that liars lie," Hadley says. I'll bet the real Sophia Isabel Velez knew that already, though. She's cool. I hope this becomes part of the family lore, like every once in while at dinner one of them will go, "remember the time that woman came to the door and said you had leukemia? And then she was all like 'liars lie' as if she was all deep and stuff. Freak." And then they'll all laugh so loud that the guy who owns the liquor store will bang on the adjoining wall and tell them to keep it down in there.
