Continuity mistake: When the Kromagg sub-commander captures Quinn in the kitchen area, Quinn is leaning back, away from the knife. The sub-commander is a good 8-12 inches shorter than Quinn. The camera angle changes, and now the sub-commander is about 6 inches taller than Quinn.

Question: In the pilot episode, the wormhole physically travels to "capture" Quinn and bring him back to his own world, after his very first slide. How did the wormhole know where Quinn was?
Chosen answer: Remember at first Quinn's timer is working perfectly (it's only because they slide off the ice age world early that it begins to malfunction) & given Quinn's intellect he would have devised a way that he could open a wormhole near him so he wouldn't be trapped on that world for 29 years.
