Our first sight of Kes was as of a kazon slave girl with a black eye, our second was of Nelix's mistress he was kissing on a transporter pad calling sweetie with the utmost concern for her so much that he started a war between the Federation and the Kason Oogla by LYING to Janeway.
The dark side of starwars fanlore says that Jabba raped Leia in Jedi, and she'd only been a slave girl for a few hours. Kes had been a slave girl for months and the black eye proved nothing else more than that they beat her until she did what she was told.
I saw a woman who was broken and then saved.
So maybe she's hopelessly emotionally indebted to the man that saved her, but after being treated like a toy in the dark cold nights by a herd of kazon miners, he'd know that he had to stand back and wait for her to repair at her own pace as slowly as necessary, which meant no nookie, perhaps forever, but then, he loved her, so it didn't matter.
Oh.
Kodos, McCoy was 137 in Encounter at Farpoint. The average human life span might be easily double 70 years.
Guy's comments are as always very straightforward but I do see many points in them.
We don't know if Kes was sexually abused by the Kazon (according to Jeri Taylor's book "Pathways" she wasn't but Taylor do have a tendency to sugar-coat everything in her stories). We also don't know if sexual abuse is an universal phenomenon even in the 24th century Delta Quadrant or if it's just a 20th-21th century Earth phenomenon.
What we do know was that Kes was beaten and ill-treated by the Kazon and that Neelix rescued her. As for the time Kes was prisoner, I assume that it was more like weeks than months.
Anyway, Neelix saved Kes because he felt sorry for her and was attracted to her and all that made him lie to Janeway and start a war between the Federation and the Kazon-Ogla.
Kes obviously felt gratitude to Neelix and worshipped him, just like a teenage girl can do in a similar situation. She obviously loved him too. Later on when she had started to live her own new life on Voyager she probably started to get tired of his supervision and jealous tantrums but that's another story.
If they had sex or not is an open question. I guess that Guy is right in his comments about Neelix standing back and waiting for her to repair at her own pace as slowly as necessary. That would explain the separate quarters, or maybe that was a part of some Starship policy: "No sharing of quarters on our ships. If you have sex, do it discreet."
Once again, the sexual habits of the species in the Delta Quadrant might differ from those on Earth. As we could see in "Elogium", they were ready to go for it to conceive a child. If they had sex later on, who knows? Maybe, but it looks like their relationship became more complicated in season 2 and onwards until it broke up in season 3.
Note that in the Voyager books "The Murdered Sun" and "Cybersong", Kes and neelix do share the same quarters. However, that must be regarded as a continuity error. The books were published during season 1 and the beginning of season 2 and the authors might have been unaware of them having different quarters at the time they started writing the stories.
