In the second season episode 12 it foretells what would happen when something like this happens. When they met the Cromags, at the end of that episode they mentioned that they put a homing device in one of the sliders. So when they do reach home they would invade it. But I'm only assuming things. I haven't seen the 4th season yet, so I'm anxious to see what happens.

I like how Rickman screamed like a girl and took a nose dive at the end. Better late then never? That guy was the most ridiculous villain ever created. The face morph was good but maybe the writers should have just wrote the fact that he can control it, (like T1000 terminator) into the script, which would have resulted in him playing possum plus hide and seek with the slider members cause they eventually get killed or scripted off anyways. Every single episode is a major movie clone. Lack of creative writing put the entire series in a hole. The whole idea of jumping to alternate reality's was great they just needed to be more like the A-Team not the SG-1 X-treme Wormhole dupes. And I thought I would get in trouble for plagiarism for writing a clone of star wars and Mel Brooks rip off, Space Balls. But dam these episodes really took the cake.Plus, how many times do you notice a script change in the middle of an episode just to fit a stupid line or to add a bigger twist? Stick to the story. You can't jump around and just assume things just because the people watching know it. Really Really Bad Writing. Fire Fly was ten times better, but it got canned after the first season. I could probably name ten others that were canned and had better writers.

Just finished looking at season 3 and want to start viewing season 4 as soon as you can.
