Don't you just hate days that start like this? While working on a patient with a grotesquely swollen tongue (and, as we will soon learn, several other nauseating symptoms), House (Hugh Laurie) is confronted by Jack Moriarty (Elias Koteas), the husband of one of his previous patients. Before anyone quite knows what's happening, Moriarty pulls out a gun and shoots House--and the motivation for this horrifying act turns out to be almost as perplexing as the act itself! Despite the blood and the pain, House insists upon continuing the job at hand, while his behavior takes a more bizarre turn than ever before. Before long, House finds it impossible to separate reality from fantasy...and that's the state of affairs as this final episode of House's second season reaches its cliffhanger climax. ~ Hal Erickson, Rovi
