House

House goes to Cuddy to get a bone saw to get a brain sample of Joe's brain. Cuddy refuses, concerned about the bio-safety hazard. She's called in the CDC but it'll take three days and Foreman only has 36 hours. House goes to Foreman in quarantine and walks him through an autopsy. Cuddy calls in security but before they can get in, Foreman goes blind without realizing it and fails to get a sample.



House and his remaining staff go over what they've tried so far and what they've eliminated, and House orders multiple treatments even though it'll mess up their tests. House goes to Joe's apartment and with Foreman's help over the phone walks through what Foreman did while using his rat. Foreman then calls his father while House watches the rat, waiting for it to manifest symptoms.



While he waits, House meets with a clinic patient whose mother reports she's been having epileptic fits. House concludes the girl has "gratification disorder." Foreman recovers his sight but now they don't know which medicine helped, and his pancreas shuts down from the treatments. House suggests they stop the treatment to buy time and Foreman agrees, and then his father Rodney shows up. House takes him to Cuddy after telling Rodney about the autopsy that could save his son's life. Cuddy explains the situation and Rodney accepts it.



Rodney then talks to Eric and Eric lies to him about the painful part of his upcoming death. House is planning how to get to Joe's corpse while Eric and his father discuss their family, particularly his mother who has Alzheimer's. They argue over Rodney's religious beliefs and Eric is skeptical – Rodney promises to pray for him.



Foreman gets worse and faster than Joe did – House seizes on the discrepancy and notes that the rat still isn't showing symptoms and may be the key. Cuddy goes to visit Eric and he's angry she isn't letting the autopsy go ahead to save his life. House arrives and notes that the cop had Legionnaire's disease – it slowed down the fatal disease in Joe. House exposes him to it after Eric refuses to be infected with Legionnaire's.



Cameron monitors Foreman as his temperature drops and the pain doesn't increase. House pursues the rat angle and wonders why Cameron isn't getting sick as well. He concludes that Foreman's body isn't recognizing the disease but then the Legionnaire's triggered the antibodies. House thinks the answer is listeria but the treatment will kill the Legionnaire's as well. Foreman insists House do a white-matter biopsy on him despite the risks. House refuses, and Foreman reluctantly concedes for now.



House goes to confront Rodney with the fact they'll be putting Foreman in a coma. Rodney agrees to let House make the medical decisions, trusting Eric's description of him as the best doctor Foreman knows. Foreman wants Cameron to act as his medical proxy and apologizes for stealing her article. Cameron refuses to accept his apology but agrees to act as his proxy. She tells House they need to do the biopsy but House refuses.



Chase talks to Rodney and advises him to tell Eric he loves him. Rodney visits his son in quarantine and assures him, asserting he knows it'll turn out okay. They have a tender moment and then Cameron induces the coma…but not before accepting his apology.



Wilson meets with House to tell him to do the biopsy since Eric only has four hours left. Cameron comes in to order the biopsy, revealing she is his proxy. Rodney is upset that Eric didn't trust him but Cameron is insistent. House asks for one hour to go back to Joe's apartment and find a dead animal they can do a biopsy on. House goes in without a suit and finds a blind pigeon. The pigeon flies away but he spots a leaking pipe and concludes the water for Joe's marijuana is on a timed system. House figures out it's on a separate water system and determines the culprit is the Naegleria parasite...but Cameron has already determined that from the biopsy she ordered.



Cameron tells Rodney that Eric can be cured of the disease… but they don't know how the biopsy affected him. Foreman eventually wakes up and his brain is fine... but when he is asked to wiggle his left toes he moves his right, and when he tries to raise his right arm, he raises his left instead.
