Character mistake: Episode 6.12, Moving the Chains: Marcus tells House that he and Eric were arrested for stealing a car, he was 16 and Eric was 14. He also says that his brother never did anything criminal after that. In season 1, we were told that Eric was 16 when he was arrested for stealing a car.
Factual error: During the differential, Chase suggests the underlying condition is a systemic infection. House says this is unlikely since the patient received IV antibiotics the previous week. However, the doctor in the intro scene remarks that he thought the patient had C. Diff, which is treated with oral vancomycin, not IV. Oral vancomycin has next to no oral absorption, and would not treat a systemic infection. Moreover, even if vancomycin was orally absorbed, it would only treat infections caused by gram positive organisms and not other infections caused by gram negative organisms. (00:12:30)
