"all things" is the seventeenth episode of the seventh season of the American science fiction television series The X-Files. Written and directed by lead actress Gillian Anderson, it first aired on April 9, 2000, on the Fox network. The episode is unconnected to the wider mythology of The X-Files and functions as a "Monster-of-the-Week" story. Watched by 12.18 million people, the initial broadcast had a Nielsen household rating of 7.1. The episode received mixed reviews from critics; many called the dialogue pretentious and criticized the characterization of Scully. However, viewer response was generally positive.
The series centers on Federal Bureau of Investigation (FBI) special agents Fox Mulder (David Duchovny) and Dana Scully (Anderson) who work on cases linked to the paranormal, called "X-Files". Mulder is a believer in the paranormal. The skeptical Scully was initially assigned to debunk his work, but the two have developed a deep friendship. In this episode, a series of coincidences lead Scully to meet Dr. Daniel Waterston (Nicolas Surovy), a married man with whom she had an affair while at medical school. After Waterston slips into a coma, Scully puts aside her skepticism and seeks out alternative medicine to save Waterston.
