Huh? "Mosaic" was a flashback novel relating the story of Janeway's pre-Voyager family life and career. Kes was barely in it. "Pathways" was a collection of "origin stories" of all the other main characters, told round the campfire. Kes had already left the show, so Taylor had to rewrite the Kes tale to be channeled by Neelix. Neither of which example proves your claim that Jeri Taylor told lies. When a show-runner says a character is hard to write for, and therefore not working as they'd like, they are obviously not telling you all the reasons why that is so. But the writers certainly painted themselves into a corner. Kes was scheduled to become an old woman - very soon - wearing expensive latex wrinkles in every episode till the end. But... ideas and opportunities can be exhausted. Unemployment and auditions. It worked. Wil Wheaton got more fan mail than any other character while he was on the show, AFAIK. I thought it was that he was originally scheduled to be killed off in the cliffhanger of the pilot episode, but they decided to keep him. This decision was before any episodes had aired.
