Regarding the Kazon and their [unspecified length greater than S02E24 but less than S07E26]
story arc, I really feel that if Voyager is "rebooted" at some point in the future that the writer's will learn their lesson and fix the glitch. There is no way the Kazon should have been able to control that much space, and even less of a way for all the Mages to get together in Alliances! It would have taken some of those Mages years to get to the conference.
NuBSG ended up really good because they learned their lessons from the original BSG.
Oh, and for the record, I hope nobody reboots Voyager.
And, for the OP, it gets better, hang on. I'll keep this spoiler-free, so enjoy the ride!
