I had a look around your website Lynx! Yes you are quite a Kes fan. On my third watching of VOY all the way through I warmed to her a bit but that was about it. I did think her backstory in Pathways was very interesting.
I think she was more stubborn then weak or passive.. but she was very quietly spoken so she appeared passive. This is is especially true if you contrast her with the other VOY women. Her manner was extremely gentle, which can be mistaken for passivity.
