who shot house at the end of season 2
No Reason (House) As House and his team work on the diagnosis of Vincent, a man with a giant swollen tongue and a high temperature, a disgruntled former patient named Jack Moriarty walks into House's office and shoots House twice with a handgun. Vincent develops two additional symptoms: blood leaking into his left eye, causing it to swell outward (and eventually be removed), and a burst testicle. The symptoms appear to have no possible connection to each other.
