House

Dr. Ezra Powell is working in his laboratory and experimenting on rats with a cancer cure. As he begins a dissection he has an attack and collapses to the ground.

House comes in with the report on Powell but his team is initially more interested in the fact House is back on his cane. House proposes putting Powell on a treadmill to run a stress test to see if his heart or lungs are causing the problem. Cameron administers the test while the others look on, but Powell quickly gives out. House okays the removal of fluid from Powell's lungs so he can take the test.

House is seeing a congested man XXX at the clinic as his daughter SSS looks on. SSS is attracted with House, much to Cameron's distaste. House watches with his team as Powell goes through the stress test without results until House administers a stimulant. They still get no results and Powell demands that Cameron help him die.

The team distress the ethics of assisted suicide and Powell demands that they stop treating him. House administers a lung test but Powell still refuses until House bargains for one more day and agrees to help him die if he can't come up with anything. Cameron checks out Powell's lab and Foreman runs more tests on Powell. the next morning they don't have anything but House suspects a problem with his brain and they run a MRI. Wilson checks the tests which turn up negative for leukemia.

They go in and… House lies to Powell. Powell doesn't buy it and House tries to get more time. Powell refuses and House prepares to inject him with morphine. After a brief resistance, Foreman storms out and Cameron follows. Once Powell's out, it turns out it wasn't a fatal dose, and House runs a tube down his chest and continues the tests.

House notices that Cameron scanned low on the MRI and picked up signs of scarring on the lungs. Chase and Foreman work on him while Cameron withdraws, and Cuddy talks to House but she's okay with hi decision to keep Powell alive. Powell has another seizure and House proposes an open-lung biopsy. House directs Cameron to some magazine article showing Powell did dangerous experimental procedures on babies, apparently to make her feel less sympathetic to Powell. Air starts to build up in Powell's lungs and House does an emergency operation to save him, then notices Powell has no pain reaction on one side of his body, but they'll have to wake him up to test further.

House is there when Powell wakes up and is none too thrilled, and House runs some impromptu sensory tests. Something is affecting the lungs and the nervous system so House needs to get a skin sample. He sends Cameron to get it and tells her to do her job. She confronts him over his experiments but he's unrepentant and she takes a stand… and a skin sample.

Ali, who has been calling House non-stop, stops by to chat with House and he shut her down… for now. House connects from her red thong to using congo red to use as a stain to detect amyloidosis, and the test comes up positive, but it's terminal. Powell can do nothing but die and Cuddy mentions to him the next morning that he passed away at 2:30 after being stable at 2 a.m. House doesn't answer her question as to what he knows about it. Later in the chapel, House tells Cameron that he's proud of her.
