I was trying tro relate to kablez's context statement to be honest, though now I'm wishing I hadn't so my position would be clearer. But her literal age really doesn't matter; her "world experience" is what matters. Or her lack thereof rather. Neelix, at times, seem's to be taking advantage of someone who is young and naive. Neelix absolutely does evolve past it and becomes quite good friends with Tom later on. The last scene of "Parturition" always makes me smile. But up until that point I always find Neelix and Kes's scenes a little bit cringey.
