- In reality, Henry Mills was given up for adoption by Emma, and became the adopted son of Regina. Henry grew up believing (correctly) that Storybrooke was a by-product of the Dark Curse and that everyone in it were once denizens of the Enchanted Forest. Upon Emma breaking the curse, she and Regina share joint custody over Henry.
- By the end of the show, he grows close to adult Henry and Regina, even calling Regina, Mom.
