A 6-year-old girl suffers ailments expected in patients much older. Tensions between Chase and Cameron lead House to intentionally assign them to the same tasks, including investigating the young girl's home.
The ex-marine that saved House's life, in a dream he had the day before, is admitted in the hospital with symptoms resembling Gulf War Syndrome. While House is busy dealing with his own health issues, and Chase and Cameron are too busy with each other, the ex-marine gets worse.
Wilson arranges for House to make a deal with Tritter, but House refuses. Meanwhile, Cuddy cuts House off Vicodin and removes him from the team's case: a 15-year-old little person who entered the hospital with a collapsed lung and anemia.
While House is forced to work full-time in the clinic and deal with a rape victim who insists on confiding with him, Cameron deals with a terminal cancer patient trying to take advantage of her state of mind.
