Nicky, you are proving my point. Hades still hasn't done anything wrong. A life for a life is a rule and Emma's trying to break that rule.

Let's not specualte Farerb because Emma did choose her family over Hook in Swan Song when it came to the worst. Emma's price will likely be her mother's life and I'm certain Emma will break or at least try to break that rule. So, in essence, Emma is the villain.
