Like how it's obvious that in S1 P&S weren't intended to be the princesses of Heaven (Garterbelt constantly treating them like trash, throwing Panty in the streets when she loses her powers (sure it was a ruse but it wouldn't be believable if she was the daughter of the big boss)). God/Judgment being their "mom" seemed to suggest her being the mother of all angels, but then for S2 they decided to make her their actual mother and their father the king of Heaven and even add an uncle and cousins.
