Back at the Clinic, the baby is back with more nose problems. House uses some Mob mentality and threatens to snap the baby's nose off if it doesn't stop crying and squirming. It works, and House pulls a tiny firetruck out of his nose. Older brother says his brother isn't very smart, and, of course, House says that genetics are powerful. He sets the firetruck down next to the fireman and the policeman, and then he has a thought. He grabs some crazy electromagnet thing out of the cabinet, saying he's always wanted to use it, and sticks it under the baby's nose. A large metal cat figurine pops out, and House compliments the baby on his well-developed sense of relationships, which we already knew when he did exactly what the dangerous mobster told him to, already making his sense of relationships better than Chase's. House explains that the baby stuck the police and fire people up his nose to save the cat. Great, but how did House know that whatever was up there was made of metal? Or that it wouldn't rip the baby's nose off on its way out? And how can you be smart enough to identify safety officers, but still stupid enough to stick a metal cat up your nose? It all gives House an idea, and he rushes off.
House writes questions to himself on the whiteboard. Why did Joey go into the coma, and why did he come out of it? Chase enters to report that Joey is not improving, and asks House whether he has an explanation for the estrogen thing. House says he does, but that he's not telling anyone. Chase takes that to mean that House thinks he's the one who told on him to Vogler. House says that Chase is at the top of the list, and, getting back to their dying patient, that the only coma you could come out of so quickly is a toxic one. Chase says that wouldn't explain the second coma, since all of Joey's food and environmental stuff has been strictly monitored. And also, he totally didn't tell on House to Vogler. Joey ate steak before his first coma, and fish sticks before the second. House can trust Chase, really. House says that Chase's assertions of honesty don't really mean anything, and leaves.
