To your first question:
If I remember it correctly, Indivi answered the question a long time ago, that raising a child wouldn’t fit the life of an adventurer, so that it would only be one possible ending.
There was also a reason, for the NPC’s to not raise a child, but I don’t remember what it was.
About the third question:
I don’t think so. But I don’t know why I think so.
So that means I can't raise a child? Darn...
Welp, I guess that's kinda sucks, but that's okay by me. I mean, it's Indivi's choice whether they'll* add that feature or not.
Also, I really have high hopes for impregnation for Fawn's post-event. Since I've learn the fact that Cassie is impregnable after rescuing her (finishing her route), why not Fawn?
*not assuming Indivi's gender btw.
