'''Season 4, Episode 17''':
!A Constellation of Doubt

As the rest of Moya's crew searches (in vain) for any mention of Katratzi on any information or communication network, Crichton retreats into his quarters, where he's using a TV brought from Earth to watch a show that Pilot intercepted via the wormhole. In it, [[DocumentaryEpisode a reporter casts doubt and suspicion on the visit to Earth by Moya's crew, and line up experts on science, religion and war to provide commentary on what the crew have to say about humanity.]] D'Argo, Chiana and even Sikozu get concerned with Crichton's new obsession, but he's convinced that he's heard the name "Katratzi" and that the clue to figuring out ''where'' can be found somewhere in the TV programme.

Finally it clicks when he sees some video footage of Sikozu examining a metal tray and holding it up so that it covers half her face. Crichton remembers why "Katratzi" is familiar: when he visited the unrealized reality where everyone seemed to be someone else (i.e. D'Argo as Jool, Aeryn as Chiana), he heard Sikozu-as-Stark say the word "Katrazi" while crossing someone over. Realising what he needs to do, Crichton asks D'Argo and Pilot if they can take Moya back to the wormhole leading to Earth, then goes to see Scorpius.

->'''Crichton''': You set me up, not that I care. I don't care about much. War... death... and wormholes. I don't care about the things you care about. Peacekeepers rule the Scarrans, the Scarrans rule the Peacekeepers. Let them rule together, put your ass in a cage. I care about one thing. One. God have mercy on my soul... I think I'm going to need your help, Mr. Scarran half-breed, to get Aeryn back. Help me get her, and I will give you wormholes. I have an idea of how to find the Scarran base. Aeryn for wormholes. That's the deal.

!Tropes present in this episode include:

* AccentuateTheNegative: A few of the "experts" on the documentary believe everything the aliens say to be either highly offensive or a deliberate psychological attack on humanity, which Crichton lets color his opinion of the whole thing. However, just as many of them, and the program overall, take a fairly positive and optimistic interpretation (which is why his family released the footage in the first place).
* BrickJoke: Noranti is making rat poison just to play with Earth's plant life early on. Twenty minutes later, Chiana is weeping because her pet rat inexplicably died.
* CallBack: D'Argo shows Bobby a recording of what happened to [[Recap/FarscapeS03E22DogWithTwoBones the rogue Leviathan]].
* CreatorCameo: Executive Producers David Kemper and Brian Henson play two of the experts interviewed for the [[ShowWithinAShow documentary]].
* CreditsPushback: Parodied. The usual end credits start up, but all of a sudden a promo for the ShowWithinAShow's next episode begins playing. The sequence directly recreates the style in which the Sci-Fi Channel would push back credits at the time.
* EurekaMoment: Crichton remembers [[Recap/FarscapeS04E11UnrealizedReality where he heard "Katrazi"]] when he sees a clip of of Sikozu where half of her face is obscured.
* FriendToAllLivingThings: Chiana is devastated by the death of a rat.
* HiddenDepths: Based on the clip, Sikozu practices singing when no one else is around.
* HumansThroughAlienEyes: Through Human Eyes. The aliens comment on humans, then the humans comment on the comments. Then Crichton comments on those, and the crew comments on his comments on the comments on the comments. The episode is 90% comments by volume.
* IntimateTelecommunications: Apparently Rygel discovered sex chatlines during his time on Earth and ''really'' enjoyed them.
-->'''Rygel:''' ''(lasciviously)'' You can call females too. 1-900-SLUT GIRL.
* OhCrap: Bobby is completely stunned over how D'Argo's ship completely vaporized a Leviathan.
* {{Retcon}}: In [[Recap/FarscapeS04E13TerraFirma "Terra Firma"]], Crichton's narration referred to Bobby as "my cousin". This episode changes their relationship to uncle and nephew.
* SmallRoleBigImpact: Bobby. His documentary gives Crichton a vital clue over where he needs to go in order to find Aeryn.
