There is one episode that strikes fear into the hearts of al X-Files fans, and many viewers will be happy to know that the revival's fourth episode has nothing to do with the Peacock family. Instead, the Glen Morgan hour will dive into Scully's (Gillian Anderson) personal life.

"Mulder and Scully are sent to investigate the murder of a city official, which it seems no human could have committed," Fox teased. "Meanwhile, Scully deals with a personal tragedy, which brings up many old feelings about the child she gave away for adoption."
