One day Kass, you're going to be in a position where there's a baby in your belly and when you tell the father that he is the father, this genius is going to reflexively reply "Are you sure it's mine?" and you're going to have to resist the massive and clinically sane impulse to back hand the bastard in the jaw with the intent to spray his teeth about the room like they were the chief prizes in a lolly scramble. I'm not saying anything bad about you or your special someone, but this is just how the universe predictably unwinds.
Now Sam was drugged, hypnotized and lost three days, whereafter frankly in regards to the Kitarian which we saw in TNG The Game who looked nothing, NOTHING like Naomi, so much so that it's not impossible to assume that everyone on board the ship had had their memories altered also when Caretaker was editing the ships database as to what a Kitarian looked like.
This is how the Cuckoo operates.
The Mommy Birds lay their eggs in other birds nests, then the new born Cuckoo's eat the other young seconds after hatching and wander off smugly proud of how clever they are.
If Caretaker was Naomi's pater, it's more than feasible that Caretaker wanted Naomi to get to earth to fulfil some manifest destiny which in all likeliness was to erect a new homeworld for the Ocampa on top of the razed foundations of whatever is left of Earth by the time she's finished expressing her point of view.
(Neelix said this happened a lot, that Caretaker was randy. It's the reverse of what the Dominion did with Odo and all the other foundlings. So that 80 ships thereabouts carrying his children, all with the impetus that all their bases now belong to him? The Ocampa would only need 80 homeworlds if they breed like Tribbles, and maybe they do?)
Season 8 of Voyager would have been Naomi vs. the Entire Federation, and mark me, she would have had the power to turn wholesale species to the last quarter into fertilizer, if she chose to exercise the powers we've seen these Nacene posses but with an inch of brutality.
