Why didn't they do an episode that's sort of the reverse of Yesterday's Enterprise where something effects the timeline and they are suddenly in the AQ (or a version of the AQ) that's closer to what it would have been if they never left. Then it's clear they have to make things right in order to push themselves back in to the DQ. They all realize at some point that their "proper present" is in the DQ, so they have to do whatever they need to do to fix things (reluctantly and then only at the insistence of Janeway of course) and then they are all back where they left off. Seems like that would have been cool. Could have included some cameos from TNG or DS9 cast. Perhaps in this alternate universe, Yar is still alive too (KIDDING)!
