What Was Lost (1): Sacrifice - S4-E2
Continuity mistake: After Oo-Nii tells John that the old woman stole his gun to kill Vella, John looks down at his holster and finds Winona gone. Later while he's shouting for Granny, it keeps cutting to the old woman while she's holding Winona, and after she whispers, "Receive the spirit," it cuts to John and Winona can be seen in the holster on John's leg, but in the next shot Granny still has it.
Continuity mistake: When John and his father are talking about the alien tech, while John's eating popcorn his father's holding a mug and points, but next shot he's still pointing and now the mug's suddenly on the table.
Bad Timing - S4-E22
Continuity mistake: At the end, 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.
Bad Timing - S4-E22
Continuity mistake: When John's at Serenity Base, in the shots from inside the pod when Aeryn looks out the window John's standing beside the flag and their long shadows are cast behind them as he looks toward Earth, but when John's on the phone with Jack, in the overhead shots the shadows are being cast in front of him.
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.
