Re-watching X-Files, and I want to skip monster-of-the-week episodes if they don’t advance the story arc. I can't remember which site used to list this information, and Wikipedia isn’t super reliable in this aspect either. Any suggestions?

Edit: IMO, the absolute best and most complete list of mytharc episodes can be culled from InsideTheX.co.uk (they’re the ones whose titles are followed by asterisks).

  • I've made a list on my computer. You can pop over to my desk if you want to have a look. (I guess depending on where you live, that might not be quick enough.) Sep 3, 2013 at 12:20
  • How funny. I want the inverse list. I hate the arc. Jun 11, 2014 at 20:38

I think this list should give you all the episodes. They released a four volume collection a few years back of Mythology-only episodes, so this can be considered a definitive list.

There is also a reference book that has a listing of the mythology episodes. The DVD's and the book differ on a few episodes, I believe it is mainly episodes that are Monster of the Week but have a Mythology-arc character show up somewhere in the episode.

The list:

Season 1
Deep Throat
Fallen Angel
The Erlenmeyer Flask

Season 2
Little Green Men
Duane Barry
One Breath (DVD only)
Red Museum
End Game

Season 3
The Blessing Way
Paper Clip
Piper Maru
Talitha Cumi

Season 4
Memento Mori
Tempus Fugit
Zero Sum
Demons (book only)

Season 5
Redux II
Christmas Carol (book only)
Emily (book only)
Patient X
The Red and the Black
The End

Season 6
The Beginning
S.R. 819
Two Fathers
One Son

Season 7
The Sixth Extinction
The Sixth Extinction II: Amor Fati
Sein Und Zeit
Closure (DVD only)
En Ami
Requiem (DVD only)

Season 8
Per Manum
The Gift (book only)
This Is Not Happening
Three Words

Season 9
Nothing Important Happened Today
Nothing Important Happened Today II
Trust No 1
Providence (DVD only)
Jump the Shark (book only)
The Truth

    I tried to figure this out from Wikipedia a while back (for no apparent reason). My list matched this, except for some reason I also included: Season 2: The Host, Sleepless; Season 4: Musings of a Cigarette Smoking Man; Season 5: Unusual Suspects; Season 6: Dreamland I & II; Season 8: Empedocles.

    I could see "Sleepless" (since I think there was some important early Alex Krycek stuff in there) and "Musings..." (some mythology bits seen in flashback). Can't think of anything super-important in the others you listed, though. I might add "Wetwired" from the 3rd season (we learn some details about Mr. X's role in the conspiracy). Mar 7, 2012 at 17:13

    I think you really have to include "Eve" from Season 1. They get into human cloning and Deep Throat is in it.

    Leonard Betts from season 4 is also a possible inclusion. While it is a MOTW episode, it's also the one that reveals Scully's cancer. Nov 3, 2014 at 2:17
  • this list is a little out of order - here is an ordered list on reddit reddit.com/r/XFiles/comments/33zhcr/… Jan 12, 2016 at 3:13
