Well, if we have to nit-pick, then all of the characters should have been dumped after season 3 because none of them had any arc to talk about.Why only Kes?
Have you read The Eternal Tide yet Lynx? Kes is in that.
Yes, I have! However, I do have some mixed emotions about it.
First of all, I'm very happy that Janeway is back!
As for Kes, I'm, happy that the character is described in a positive light and that there's no "Fury" crap involved.
But i'm not that happy over the scenario with Kes back on Ocampa and so on. I would like to have her back on the ship as a member of the crew.
But, as Mick Jagger once wrote: "You can't always get what you want."
