Continuity mistake: At the end of "Bad Timing", the final shot of the boat with Aeryn & John crystalized shows that their pulse pistols are still there and intact. But when they are reconstituted at the beginning of "The Peacekeeper Wars", the pistols reappear on their belts for them to draw.
Visible crew/equipment: After John successfully instructs Aeryn on how to maneuver and slingshot Moya away from the PK's Command Carrier, Zhaan gives John a very special thank you. When it cuts to the DRD scooting across the floor in Moya's empty Command, a crew member wearing shorts can be seen at the right side of the screen, as he's looking in the direction of the DRD, and is presumably controlling the DRD's remote control.
Visible crew/equipment: After Matala's shuttle and the Scorvian cruiser are torn apart by the black hole, when it cuts to Rygel in the galley as he burps just before John walks in, we can see the puppeteer's right arm and hand (wearing a wedding ring) behind Rygel.
Revealing mistake: After Rygel realizes that he can loosen the soil with the dumped gruel, it cuts to John and Aeryn as they approach the Tavlek camp, and when Aeryn tells John, "I am going to take out every last Tavlek. No survivors. No mercy. Now give me the oculars," John holds up the syringe (with Zhaan's sleep mist) that Aeryn had given him earlier, and we can see "DG-4" engraved on the side of the gun, revealing that the prop dept used the model DG-4 aluminum air blow dust gun to play the part of the syringe.
Visible crew/equipment: Aboard the Zelbinion, when Aeryn and John question Gilina about how the Zelbinion died, after Gilina says, "Officer Sun, I think you should know, I consider you a traitor...," when it cuts to Rygel in his hoverchair with his flashlight in hand, there's puppeteer movement behind him. Later, after Zhaan tells Rygel to find Durka's corpse because it'll set him free, when Rygel's back aboard the Zelbinion, although he's just remembering being in a cage in front of Durka, it's interesting to note that we can see the puppeteer's movement behind Rygel.
Visible crew/equipment: After Aeryn extracts the worm from John's abdomen, when Rygel says, "If I were warmer, I would have an appropriately venomous reply. Be warned, I owe you one," he drops down off the table, and as Rygel waddles away the boom mic dips into view at the top right side of the screen.
Continuity mistake: When D'Argo, Aeryn and John start their search for clorium, D'Argo is wearing arm bracers which extend over the palm and back of his hands. After John says, "Pilot said you press this, this and...this. Works just like a VCR, except easier," D'Argo grabs the particle analyzer from John, but in the closeup of the particle analyzer the hands we see are bare, which means it's not D'Argo, then in the next shot D'Argo is still holding the device.
Visible crew/equipment: While Rygel watches over John's body, Rygel performs his own version of the Hynerian Ceremony of Passage to declare John dead so as to claim John's possessions, and when he pulls at John's boots, the puppeteer's arm/elbow becomes visible behind Rygel.
Continuity mistake: In the scene where Crichton and Crais are fighting with the chains in the room with the metal whirly-gig you see Crichton fall and Crais wraps the chain around Crichton's boot. In the very next shot you see Crais yank on the chain with all his might, but the chain is now attached to Crichton's hand instead of his boot.
Visible crew/equipment: While Rygel's in his quarters tossing out his junk, when D'Argo walks in and asks him about it, as Rygel replies, "Just items that I've procured since our escape," the hand of the puppeteer can be seen behind Rygel at the left side of the screen.
Visible crew/equipment: After D'Argo finds the Peacekeeper control panel and rips out the wire, he's thrown back and slides down a shaft. When he stops sliding we can see the safety cable behind him just before he finds the Peacekeeper shield, and then when he continues to slide down the shaft we can see the safety cable once again.
Continuity mistake: When Rorf and Rorg are firing at John and D'Argo who are pinned down in an area with no "back door," the lens surface on John's goggles are scratched/cracked, but once John makes the comment about soldiers of fortune and Aeryn walks out, the small holes on both lenses are now perfectly intact.
Visible crew/equipment: After Aeryn tells Furlow that she cannot see, it cuts to Zhaan as she enters the command deck, and when Rygel asks her if she's fully clothed Rygel lifts his arms to cover his eyes, and we can see both of the puppeteer's arms up in both of Rygel's sleeves.
