Season seven takes place after the destruction of the Syndicate, which marked the end of their long-running story arc. This season marks the end of various other story lines, most notably the revelation of Samantha Mulder's fate to her brother, Fox Mulder.

The season explores various themes such as life, death, and belief.
Season eight was received well by critics but got more mixed reviews by fans and viewers, since David Duchovny elected to return only as an intermittent main character, meaning that he appeared in only half of the episodes.

Duchovny appeared for only twelve episodes in season eight, and reduced his time on The X-Files dramatically in season 9. "This Is Not Happening" marked the first appearance of Annabeth Gish as Monica Reyes, who would become a main character in season 9 as Doggett's new partner in the X-Files office.
