I've explained this to all of you before but it seems people just don't retain the facts.
Janeway will be having a baby with 7. Their genetics, their DNA, no one else. Since they are both super busy and important people the baby will be gestated by Harry Kim and when it is delivered caesarean section Neelix can be its nursemaid. Harry Kim will get a girlfriend out of this in the end because he will now have a manly scar on his stomach and chicks dig scars.
