Continuity Notes



Season 8: Episode 1

8x01 Within

An FBI taskforce is organized to hunt for Fox Mulderbut Dana Scully suspects the taskforce leader, Special Agent John Doggett, and instead chooses to search for her lost partner with Walter Skinner.


This episode marks the first change in the opening credits, and the introduction of Robert Patrick as Agent John Doggett. Gibson Praise also returns. Kersh is made Deputy Director of the FBI.

Although phone records are shown which indicate a March 11th date for the episode, that's impossible based on internal evidence, which indicate this takes place about two days after the events of 7x22: "Requiem." The phone dates would indicate 8 months have passed since then, which, given Scully's pregnancy, clearly cannot be. Perhaps the internal computer clock was off (possible due to unresolved Y2K issues), and the FBI are aware of it (which is why Skinner doesn't point it out to the interrogators).


According to Doggett's findings, car rental receipts on Mulder's Visa reveal he traveled to the same place four consecutive weekends in May. This would indicate he was abducted between the 29th and 31st, as per Doggett who in 8x11: "The Gift" says Mulder was abducted in May.

June 1-2, 2000


Season 8: Episode 2

8x02 Without

At a remote school in the Arizona desert, Doggett, Scully, Gibson and Skinner–as well as a host of students and agents–do not know who to trust as the bounty hunter works among them; and–in a spaceship close by–Mulder is experimented on.

Gibson Praise is put into protective custody. Agent Doggett is assigned to be Scully's partner on the X-Files.

June 2-5, 2000


Season 8: Episode 3

8x04 Patience

Having been assigned to the X-Files, John Doggett joins Scully to investigate a series of gruesome murders that appear to be the work of a bat-like creature. This being their first case together, Scully and Doggett find that their investigative techniques are less than similar.

This is the first episode in which David Duchovny's name does not appear in the opening credits.  At least a few weeks of recovery time is required based on the extent of Scully's injuries.  Episode begins on a Monday.

June 12-17, 2000

Action takes place over the course of the first two days and last day.


Season 8: Episode 4

8x05 Roadrunners

Working alone, Scully pursues a cult that worship a slug-like organism; but in her efforts to save an injured stranger, she discovers she's in over her head.

No internal dates provided. Episode begins on a monday.

July 10-18, 2000

Action takes place over the course of first two days and last day.


Season 8: Episode 7

8x07 Via Negativa

Doggett and Skinner work to avert the murderous spree of a religious cult leader, while Scully takes time off to deal with the early stages of her pregnancy.

Dogget meets the Lone Gunmen for the 1st time

No internal dating

Late July


Season 8: Episode 13

8x08 Per Manum

Scully becomes personally involved when she encounters several women who had no way of naturally conceiving but who claim to have been abducted and impregnated with alien babies.

Scully's baby is fourteen weeks old. Given that she announced her pregnancy to Skinner at the very end of May, it seems likely that she conceived in mid-May, which would give a mid September date for this episode.

Mid September


Season 8: Episode 5

8x06 Invocation

Having been kidnapped for ten years, a little boy mysteriously reappears but has not aged one bit. While the case stirs up painful memories for Doggett, suspicion stirs that the boy is not all he seems.

First mention of Luke Doggett.


Dating is based on the ten year mark of the abduction of Billy Underwood.  There is no internal evidence that it's the exact anniversary date of his abduction, so given that Doggett needs recovery time, this date makes sense.



Season 8: Episode 10

8x11 The Gift

Doggett comes upon an old case about a professed ‘soul-eater’ that Mulder kept secret from Scully, which he hopes will ultimately prove the truth behind Mulder's abduction.

No internal dates provided. It is said to be roughly a "year" since Mulder visited Squamash, but given the events of Episode 8x14: This is Not Happening, it's more like under half a year. Doggett confirms that Mulder was abducted in May. He went to Squamash, PA on May 6-7, and returned there on the 24th.  Doggett also reveals that Mulder falsified case reports, which explains how the dates might be off at the end of Season 7.

Late September 2000


Season 8: Episode 14

8x14 This is Not Happening

Doggett calls on another agent, Monica Reyes (Annabeth Gish), to assist in the Mulder case, but Scully's fears about finding him come to a head with the sudden recovery of abductees seized at the same time.

Passport indicates this can be no earlier than 11/16/00.

Mid November 2000

8x10 Salvage

Mid November 2000


Season 8: Episode 8

8x09 Surekill

The fatal shooting of a realtor while alone in a cinderblock jail cell has Doggett hoping motive will yield more than method, but they soon learn that there is more to this case than meets the eye.

January dates appear on billing receipts, and the accountant states they're from last month. This would make it February, the same month Scully is giving birth, yet is impossible as she's not showing, which indicates that either the billing dates are erroneous, a "1" is missing, or that the receipts run several months from January of the prior year, which we don't see on screen.

Late November/Early December 2000


Season 8: Episode 6

8x03 Redrum

After his wife is murdered, a lawyer friend of Doggett's tries to clear his name of the crime but the days regress backwards.

Mulder still in hospital. He says that Scully will be going into labor in "a couple months," which is specifically in mid-February, placing this episode in January. Frohike says Mulder's been dead for "six months," which would imply that he died in July, yet he says this in the context of a joke, and it seems likely the "six months dead" is also meant in jest.

Early January 2001
