Till the Blood Runs Clear - S1-E11
Revealing mistake: While John and Aeryn are in the module, which is leaking plasma, just as Pilot tells them that Moya does not want to put her baby at risk, we can see the puppeteer rods controlling Pilot's arms as they move.
Till the Blood Runs Clear - S1-E11
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.
Chosen answer: It's never explained. John mentions a theory that his less technologically developed craft simply interferes with the wormhole less than the "superior" Vipers, but they never make a concrete determination on that point. But we also have to take into account the fact that Moya traverses wormholes with no ill effect as well.
