Stuart is a coma patient in the Season 7 episode Family Practice. After House is ostensibly thrown off of Arlene Cuddy's case, he has to distract Martha M. Masters who will obviously squeal on him once she finds out they're still working on the case. As a result, he pretends that Stuart may have a treatable condition and manipulates Masters into running an invasive test in violation of a standing order not to do tests without the family's consent. Masters is so upset she vomits in the nearest toilet. However, she tells Dr. Kaufman anyway.
