"Why doesn't Prince Philip or Mulan know who Snow White is?" a fan asked.
"They weren't from the same neighborhood," Jane replied.
This makes sense to us. Fairytale Land is vast, with multiple kingdoms. And it's not like they have TV or the internet there — if someone wasn't from around Snow White's kingdom, there's no real reason they should know what she looks like, or even much about her.
Of course, that doesn't explain why Mulan and Sleeping Beauty apparently didn't let Snow and Emma explain themselves before treating them roughly. But they've been through a lot, so we'll give them the benefit of the doubt — even if we don't approve of anyone tying up our favorite fierce mother-daughter duo.
