House M.D. Season 2 Episode 21

Foreman's state worsens, blind although he didn't even notice it. Cuddy refuses permission to use the infected cop's body, so House can only use pet rat Steve as a lab animal. He orders combined treatment for all kinds of agents. It works but the drugs soon overload his system. The Foreman's medical proxy goes to Cameron rather than Rodney who would blindly follow House.
