I'm not questioning the possibilities: I'm questioning the mechanics. And in a binary conception environment, having a surplus of one half means it's pretty much by default complicated. If they just came out (ha!) and said "Oh, the kids are all adopted. We wanted to rescue war orphans." I would be awesome with that cause it builds backstory for all the characters involved including the ones we've yet to meet (all of bo's siblings.).
If they said: oh, we just went to the wizards and they helped us every time; that would be awesome too cause cause I'm only interested in them addressing it.
