List of The X-Files episodes

"Paper Hearts" is the tenth episode of the fourth season of the American science fiction television series The X-Files. It premiered on the Fox network on December 15, 1996. It was written by Vince Gilligan, directed by Rob Bowman, and featured guest appearances by Tom Noonan, Rebecca Toolan and Vanessa Morley. The episode is a "Monster-of-the-Week" story, unconnected to the series' wider mythology. "Paper Hearts" was viewed by 16.59 million people in its initial broadcast, and received positive reviews, with critics praising Noonan's guest role.

The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson), who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, and the skeptical Scully has been assigned to debunk his work. In this episode, Mulder and Scully find that a child killer (Tom Noonan) who Mulder had helped to apprehend several years earlier had claimed more victims than he had confessed to; and in the resulting investigation, learn that the killer is now claiming to have killed Mulder's sister Samantha.

Gilligan came up with the concept for "Paper Hearts" when thinking about the series' longest running storyline, the abduction of Samantha Mulder; he came up with a story questioning whether Samantha had not been abducted by aliens, but was rather murdered by a child killer instead. "Paper Hearts" was written specifically with Tom Noonan in mind for the role of Roche, and was amongst the first television work the actor had done.
