The Kes splinter story was in the String Theory trilogy, and it went a long way to redeeming Kes after the awful Fury. Kes is one of my very favorites, she and Janeway are my top two, so I really hated how her character was damaged so badly in this story.
I'm guessing JL didn't read the script before she agreed to do this story.
I think Fury is so bad it would've took a massive rewrite to make it work. A different, better story should've took it's place.
