Plot.
When the team takes on the case of Emily, a six-year-old girl who has numerous preexisting health problems, they must work with her mother, Elizabeth, a doctor who specializes in her daughter's condition. The team must also deal with the battles raging between Emily's mother and father who have conflicting views on how to handle her health issues. When searching the family's home for clues to Emily's illness, the team realizes that Elizabeth's determination to cure her daughter could be the very thing that is killing her. Meanwhile, House and Wilson deal with Wilson's stage two cancer at House's apartment. Wilson feels that going forward with the more radical treatments first would be the best way to deal with it instead of dying a slow death, and this puts his life in jeopardy.
