Hunting (House)

"Crystalline Green" by Goldfrapp

"Hunting" is the seventh episode of the second season of House, and twenty-ninth overall. It premiered on Fox on November 22, 2005, and was written by Liz Friedman and directed by Gloria Muzio. House is confronted by a homosexual man who demands treatment when other doctors diagnose him with AIDS, something he admits he does have. House begins making moves on Stacy using sensitive information on her relationship with Mark.

Wilson picks up House while they discuss House's theft of Stacy's treatment notes. Wilson is not pleased, particularly when he finds out Stacy and Mark are not having sex despite his recovered status. As they head out they run into a "stalker", Kalvin Ryan, who wants House to treat him. House quickly concludes his health problems stem from AIDS, but Kalvin claims that tests show that AIDS is not causing the new symptoms. After a brief struggle, Kalvin passes out into anaphylactic shock.

Cuddy insists House meets with Stacy in case Kalvin files a lawsuit, and they spar at Stacy's house as she reveals she has a rat. They share a moment before Mark interrupts, clearly upset. House accepts the case but is bored until they figure out Kalvin is showing all the signs of fighting back against the AIDS but is still getting worse. House suspects the strength of Kalvin's immune system fighting back is causing his new symptoms, and orders more tests. House then prepares to kill Stacy's rat so he can get her to reveal his feelings and get her fired, but notices its odd behavior.

While Kalvin flirts with Chase, House and Stacy head up to Stacy's attic to find the rat and share another moment, but they're interrupted by the staff calling him and updating him. House quickly prescribes some treatments but is more concerned with killing the rat he just spotted. Kalvin's tox screen shows recreational drugs and it's clear he's not too concerned with maintaining his health. He starts to cough and then bleed, spewing blood into Cameron's face.
