Black Hole (House)

A high school senior named Abby is sitting during a class discussion in a planetarium with her boyfriend, Nick. Suddenly, she starts drooling blood and sputum from her mouth. At Princeton-Plainsboro, House orders the team to do an MRI. During the MRI, she hallucinates that she is getting sucked into a black hole. Many diagnosis attempts are thwarted by negative tests. While Nick proposes to Abby, she hallucinates a younger version of herself coercing her to "tell the secret." Moments later, she begins seizing.

As a last-ditch effort to diagnose her, House and his team use an experimental procedure called "cognitive pattern recognition" to map the unconscious thoughts of Abby. This yields images of outer space and what appears to be Abby's father who had died in a plane crash. Eventually House reveals that Nick's father, a food importer traveling around the world, contracted a Middle Eastern parasite which he then inadvertently transmitted to Abby sexually, triggering a cerebellar schistosomiasis delayed hypersensitivity allergy.

Meanwhile, Wilson attempts to furnish his new condo. He rents the furniture, much to the dismay of House, who returns the furniture. Then, Wilson is seen in a furniture store trying to buy furniture, but is unable to choose anything. Finally, he hires a decorator and fills the room with furniture, buying House a Hammond B-3 organ. House is pleased with the gift and plays "A Whiter Shade of Pale".

Throughout the episode Taub is having a marital issue. His wife is upset that he is not spending enough time with her. While at work, House takes Taub's phone and sexts with Taub's wife. Later, Taub and his wife make up. Taub proposes, getting down on one knee and giving his wife a diamond ring. When she points out that they're already married, Taub responds, "I want to be better at it." However, his fidelity to his wife is questioned once again when House sees him walking with an attractive nurse as the episode ends.
