A young man buys a fancy ring in a jewelry store, then gets a little snotty at Sam and Stacy for ripping him off. He walks out with a cane that reveals he's blind. Sam says, "Such a shame he's a handicap." We follow him out to the street corner, where incredibly loud beeping makes him disoriented. He's holding his head and wandering into traffic! Cars! Trucks! Wacky camera! Siren! Opening credits!
House tells his team that he's a blind diabetic. But he's not! And his tox screens are clean, which no one ever checks before diagnosing. House is teleconferencing from somewhere. Park suggests noise-induced epilepsy to counter Chase's suggestion of auditory hallucinations.
Wilson brings a pleasant old woman into the office. Taub claims that House is at an out-of-state medical conference in Baltimore. The woman introduces herself as Blythe, House's mother.
Chase and Park enter the patient's room, where his girlfriend Melissa is tending to him. He says he's never had a seizure. Park introduces herself as being short and Asian. Her offer to let him feel her face seems weird to everyone. Melissa says that they were on a break. This leads to a comment about Friends. Will (his name is Will) insists that he doesn't have epilepsy. He'd know! Chase says there will be tests.
Blythe interrogates Wilson about how House is doing. Is he happy? He notices her medical bracelet, which she dismisses as being related to some mole removal. She refers to House as "Greg," which is creepy. Wilson notices that she has a book about dealing with terminal illness. She would like House to call her, since she's in town for three days. Then she refills her drink and (kind of ostentatiously) leaves her bag behind so Wilson can see that the book is specifically about terminal cancer.
Adams and Taub are running hearing tests on Will. Taub has opinions on how people break up. At 300 hertz, Will appears to have a seizure. But his EEG is clear! They determine that he's choking. He coughs up blood. And a tooth! I think.
Yes, it's three teeth that lodged in his throat. The team throws around ideas. Park suggests poison. House insists on periodontitis, which doesn't cover everything. House throws in broad-spectrum antibiotics.
