After Mulder's disappearance, Scully returns to FBI Headquarters to find Special Agent John Doggett heading up an FBI manhunt for her partner. Knowing that type of search will prove futile, Scully and Skinner turn to the Lone Gunmen in hopes of uncovering information about additional UFO activity around the time of Mulder's disappearance. Although such information leads them to Gibson Praise, the man with Gibson, an a man who appears to be Mulder, is in fact an alien bounty hunter. Finally realising that Mulder will not be found so easily, Agent Doggett (ie. Robert Patrick, best known as the seemingly unstoppable Terminator from Terminator 2 ), is officially assigned of the X-Files. Now after all she has been through with Mulder, it is Scully who is "the believer" and who must find a way to work with "the skeptic".

With David Duchovny only scheduled to appear in half of the season, Gillian Anderson embraced her expanded role and her moving portrayal as the heartbroken and pregnant Agent Scully reinforced the reasons why this talented actress has won an Emmy, a Golden Globe and two Sag Awards for her work on the X-Files.
