Nevil frakking Chamberlain!
Peace in our time my asymmetrical ass.
The one thing about Fury that few people fail to consider is that not only did Kes Not leave, but she made it all the way to Earth as cargo in her coffin. It's like they never fired Jennifer at all. In fact since Kes was part of every episode then between series 4 and seven Jennifer could conceivably sue Berman for back pay since they were using her virtual likeness without remuneration.
Isn't that just the most sweetest most adorable consideration?
(Starfleet is probably going to eventually use her remains to create a biological stardrive. I have no idea why Janeway didn't. 50 more years in space waddling along or defile the corpse of a crazy old lady who tried to kill her?)
