What a jolly mess they are in now. It is kind of hard to figure out why the Kromags want to get to the Sliders' original Earth, however, aside from going there to destroy their original sliding machine. It would have seemed more bright of them just to keep the timer and dispose of their hostages. Why did the aliens really go to all the hastle of releasing and watching? I guess we can't rely on mutant apes to use advanced logic. On second thought, however, perhaps the Kromags actually evolved from politicians in Washington D.C., and are trying to find their way home... which would explain a great deal.
