This question contains spoilers, but hey, the series ended in 1999.
In Exodus Part 2, they have the coordinates of our earth stored in the other timer. Remmy asks Quinn to send them immediately, but he wants to help the people first, they get into a heated argument and they fight a little.
Why didn't Quinn take them there, and then returned by himself to finish helping? The timer was native to that world so he could safely set it to 2 minutes, go, leave them there and return later.
Is there an explanation or is it just a plot hole?
