. . . What if Yang and Ruby's parents weren't in a monogamous relationship? I know it's pretty far out there, but no one seems to have mentioned it yet. What if the laws in Vale allows for multiple spouses? Yang and Ruby could share a father who had multiple wives. This would explain why they look so different, aren't step-sisters, and don't seem to bear any resentment towards each other.
