The dorm room is full of pot smoke and gross stuff. And a roommate. Taub and Adams are on the case. The roommate won't talk about drugs because he's pre-law. He does say Derek doesn't party. Then Adams finds a picture of a little boy hidden in Derek's sock drawer.

Adams and Taub go to Derek's room and try to kick his girlfriend out so they can ask him about the picture. He says she can stay. After denying that the picture is anything, he admits that the picture is his brother Christopher, who's been dead ten years. Adams: "Is that the voice you hear in your head?"

Wilson wakes up. House claims he was dead, since he had no dreams. Wilson objects to the claim that House has proven something about death. He also says that neither of them has changed the other's mind. He asks House to leave. But before House can leave, Wilson says that he's spent twenty years holding the hands of people who are just about to die. So he doesn't believe that people are just bags of chemicals.

Park asks the team if they'll be talking about the patient or waiting for House. Taub says that it's viral encephalitis, but the symptoms have been going on for ten years. Park and Adams go to distract House, but Taub says that House never listens to them. How about temporal lobe epilepsy?

Derek and his girlfriend are having an argument about whether he trusts her. Adams and Taub want to take Derek for tests and he tells the girlfriend to leave and not come back.

Epilepsy test. Strobe lights. But he feels fine and smells nothing odd. Adams asks why he won't admit that he hears his brother's voice. He says it's how he was raised. She probes a bit and he reveals that his brother was killed by a drunk driver and his father drank himself to death. He looks confused. After his father moved away, his mother hid all the pictures of Christopher and pretended he didn't exist. And just then! His right eye hurts and shortly after he could see spots. Adams says it's a clot behind his eyes.

House and Wilson look for a place to eat in the cafe, but it's too crowded. House has a story about a kid that Wilson saved and it turns out to be his first case at PPTH. And this is the kid here! Right at this booth! House: "He's going to be a doctor. Instead of being dead." The kid tells Wilson about how much good he could do if he stayed alive. And then, of course, the entire cafe is full of people who are alive today because of Wilson. It's a very nice scene. They start to tell him about the things they've gotten to do because he saved their lives, then they start applauding. House tells him that 74 children and 14 children are alive today because of him. Then Wilson tells House that Mikey Kimball would have graduated high school the previous year. In fact, nobody in the room was really a patient of Wilson's. Yeah, House shouldn't have gone back to the "hire an actor to trick Wilson" move so quickly. It was still a pretty moving moment. I mean, briefly. House says that Wilson really did save all those lives. And maybe it's more impressive that all Wilson's patients are too busy to be there? Wilson leaves.
