BEEP BEEP BEEP! Bob is screaming in pain. And understandably, too, because his skin is peeling off in huge swathes. Make-up extravaganza! And poor Jamie Bamber probably thought he was going to get to lie in bed for the whole episode. Nothing's more relaxing than pretending to be in a coma!
So Bob's getting worse, not better. Park asks if everyone's trying to think of an answer or is trying to avoid saying an answer that fits everything: Stevens-Johnson Syndrome. For which there is no treatment. House tells everyone to go home. "Case closed." Everyone leaves. Chase last.
Bob looks super-gross now. Chase looks at him from behind a surgical mask, presumably because he just couldn't bring himself to go home.. Bob feels like he's in hell. Chase says more pain medication will make his condition worse. Bob says he has one final confession to make. He claims to have killed his business partner, shooting him in the head and making it look like suicide. "And he was just the first." There were three. Or four. Chase, doing an admirable job of looking skeptical when half of his face is covered with that surgical mask I just mentioned, says,: "Try not to kill anyone else before i get back."
The team is back in the hospital, looking at a brain scan. It's an aneurysm! In the communication center of his brain. He'll confess to anything now! They demonstrate this experimentally. Park questions how this could explain the skin problem. House says it couldn't, so the aneurysm is just another symptom. The new answer is Kawasaki Disease. The key is the rug burns! It has something to do with carpet-cleaning chemicals. Fine.
House leaves, followed by Taub. House, who has a significant folder in his hand, insists that Taub say he was right. Taub says he doesn't care. House threatens to shred the file if Taub doesn't agree to go to the light box in the lab. Taub eventually stops him. Then he takes the folder, glances in it, and shreds it. "Just wanted to make sure all three were inside." House looks thoughtful. So that's the resolution!
