House finds Adam with his parents and Foreman preparing for the surgery. He tells Foreman to turn the lights off, whips out one of those lights that doctors use to look in your eyes and ears, and shines it in Adam's eye. He tells the group that Adam was telling them what was wrong with him the whole time, but since no one knew how to speak autistic, they couldn't figure it out. Fortunately, House read the title of this episode that kind of gave everything away, which I really wish the episode titles would stop doing, no matter how clever they are. House looks into Adam's eye again and finds the worms he was looking for. Ew. Ew. Ew. Adam was seeing those worms moving around and that's what those squiggly lines were. So how did he get the worms? Well, some animal took a dump in Adam's sandbox, and Adam ate the sand, infecting himself with raccoon roundworms which, conveniently enough, don't show up in stool samples and so were undetectable. Even though they tested the sand, it still didn't show up because the roundworms were not playing in that particular area of the sandbox, I guess. As the Magic Schoolbus Cam helpfully shows us, the worms took a tour around Adam's body, first in the lungs, then the liver, and then the eye. Except that they would have had to attack the eye first since Adam was seeing those squiggly lines before anything else happened. But whatever. The worms are curable and Adam will be fine.
Wilson shows up in Cuddy's office to read her some passage about Asperger's Syndrome. Wilson thinks that House fits the criteria, especially with his new inability to accept the change of carpet in his office. Cuddy says that House doesn't have Asperger's, he has Assholitis. A raging and chronic case of it. And let that be the final word on it and please stop discussing House's possible Asperger's in the forums ad nauseum. But Wilson won't let it drop; he says that House only took this case because he saw himself in the autistic kid. "He doesn't want this. He needs it," Wilson says. The scene ends here, but I'd like to believe that, had it continued, Cuddy would have told Wilson to shut up and stop coming to her just to talk about House and thrown him out of her office so he could actually do his job. Which is oncologist, not psychoanalyst. Although he's equally crappy at both.
