You also have to take into account that Jade huge-ified the window, so to them the ship is still however many meters long, and the gap is however many times larger than that. So depending on exactly how large the ship is, the distance could be as long as a few kilometers for Jade and John. Thus, relativity would mean that time moves much slower for them than it does for Hussiebot, for whom the distance is still the normal 1 meter long.
