Also, if Henry had been born out of wedlock in the Enchanted Forest, he would have been stigmatized as illegitimate, not honored as a knight of the realm or an heir to the throne.
Well, it is Emma’s wish-world, anything goes I assume.
But even if it wasn’t, while we have heard the titles Kings and Queens, we’ve never been shown how their titles are passed. Legitimacy may only an issue if the paternity is unknown *and* relevant to a child’s status. Maternity is not in question, and the mother is a princess. It would be different if a woman was claiming to have gotten pregnant by royalty (like Cora). And, unless Neal Jr is around – and males are first-in-line, then Emma is next-in-line for the Throne(s).
(Who’s kingdom are the ruling, and who is the reigning Monarch anyways? Snowing’s Kingdom, or James’ Kingdom? Or both?).
I don’t know why in Emma’s fantasy world – outside of want to wish herself been widowed by Neal (which makes no sense, wouldn’t you rather he be alive, even if just for the sake of your son?) – why she would wish for that world to follow archaic beliefs around child-legitimacy that she certainly doesn’t subscribe to herself?
