Guardian Angels

S4 E4: When a 20-year-old funeral home cosmetician, Irene, has a massive seizure, she hallucinates that the cadavers in the funeral home have come to life, House and the remaining seven fellowship candidates must figure out the cause. Thinking something in the funeral home may have made Irene sick, House sends the candidates on some less-than-desirable investigative missions, including a visit to a graveyard. As Irene’s symptoms become more life-threatening and her ghostly visions more vivid, House surmises that connecting with Irene’s mother might be the best route to diagnosing her illness. Meanwhile, Foreman finds his "House-like" reputation has preceded him as he interviews for a new job, and House must narrow down the candidates from seven to six.
