Post Traumatic Slide Syndrome - S2-E8
Plot hole: Since Quinn's double built a sliding system in his basement, our sliders could have used it to reset the timer and go home, just like they intended to do in the episode "Eggheads."
Post Traumatic Slide Syndrome - S2-E8
Continuity mistake: When Wade enters the recording studio to see Rembrandt, we can see him reflected in the window removing his headphones and handing them to an assistant. The camera angle changes and he removes the headphones (again) & puts them down on a stool.
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.
