An intriguing episode in which the patient stays in his house instead of being hospitalised. Love it. I like it when Cameron joins the differential. I miss it. Every since Cameron, Chase and Foreman leave the team, I keep hoping they'll rejoin House for at least once to solve a case. Although Chase doesn't join them, Cameron brings the old feeling back. Anyway the patient, to me, is kind of annoying. I know he has phobia, but I really have trouble believing that hospital is a dangerous place. At least compared to his house.
The final diagnosis is unexpected. I never know bullet shards can cause a damage so severe. Overall, the episode is good.
