The eighth season of the American science fiction television series The X-Files commenced airing in the United States on November 5, 2000, concluded on May 20, 2001, and consisted of twenty-one episodes. Season eight takes place after Fox Mulder's (David Duchovny) alien abduction in the seventh season. The story arc for the search of Mulder continues until the second half of the season, while a new arc about Dana Scully's (Gillian Anderson) pregnancy is formed. This arc would continue, and end, with the next season. The season explores various themes such as life, death, and belief. For this season, Duchovny elected to return only as an intermittent main character, appearing in only half of the episodes. Actor Robert Patrick was hired as a replacement for Mulder, playing John Doggett. The season also marked the first appearance of Annabeth Gish as Monica Reyes, who would become a main character in the ninth season. In addition to the cast change, series creator Chris Carter updated the opening credits, which had remained unchanged since the first season. Season eight was received well by critics but was less warmly received by fans, many of whom were unhappy that Duchovny reduced his role and that Patrick took over as co-lead alongside Anderson. Ratings for the season were initially strong, but it eventually averaged a total of 13.53 million viewers, down from the seventh season's 14.2 million. Concurrent with the airing of this season, Carter and The X-Files production team created and aired a short-lived spinoff titled The Lone Gunmen. Plot overview At the end of the seventh season finale, "Requiem", Fox Mulder (David Duchovny) was abducted by aliens. Dana Scully (Gillian Anderson) meets Special Agent John Doggett (Robert Patrick), the leader of an FBI taskforce organized to conduct a search for Mulder. Although the search ultimately proves unsuccessful, Doggett is assigned to the X-Files and works with Scully to look for explanations to several cases. When Scully learns that several women have reportedly been abducted and impregnated with alien babies, she begins to question her own pregnancy and fears for her unborn child. Doggett introduces Scully to Special Agent Monica Reyes (Annabeth Gish), an FBI specialist in ritualistic crime, shortly before Mulder's deceased body suddenly appears in a forest at night. Following Mulder's funeral, Assistant Director Walter Skinner (Mitch Pileggi) is threatened by Alex Krycek (Nicholas Lea) that he must kill Scully's baby before it
