The Right Stuff (House)

"The Right Stuff" is the second episode of the fourth season of House and the seventy-second episode overall.

A pilot, Captain Greta Cooper (played by Essence Atkins), begins hallucinating while in a United States Air Force jet simulator.

Meanwhile, House is being pressured by Cuddy to whittle down his applicant pool. He makes a show of firing many of them arbitrarily, before being paged by Cooper, who seeks to bribe him into diagnosing her off the record, as she doesn't want NASA to disqualify her from the astronaut program. House is initially uninterested, but becomes intrigued when she mentions her sudden synesthesia. House presents her to his recruits, then splits them up to run various tests — and wash his car. While talking to his applicants in his office, House thinks he sees Chase walking past the doorway. House orders Cooper into a hyperbaric chamber where Applicants 6, 18, and 24 attempt to flush out excess oxygen, but she collapses with a heart attack. They try to defibrillate, but it starts a fire in the oxygen chamber, setting off the sprinklers.

Later, they determine the heart attack was not caused by the treatment. House then sends them to run tests and look for infectious substances in the cafeteria. House confides to Wilson that he saw Chase, but Wilson says Chase is in Scottsdale, Arizona, and suggests House is feeling repressed guilt. House is not amused.

The applicants check in with House who orders thyroid tests. Cooper's temperature begins to rise. The applicants inadvertently reveal they broke into her house, and she becomes paranoid and begins to hear color again. They sedate her, but Cuddy notices and wants to know who Cooper is. House thinks he sees Cameron walk through the lobby.
