I actually think that Emma used Henry's heart to cast the Curse that brought them from Camelot to Storybrooke. It's confirmed by A&E that someone did lose their heart, and a Dark Curse can rip people from their land. But you have to use the Heart of The Thing You Love Most. "The Dark Swan", Emma hates everyone but Henry, even saying "You didn't fail me". While Dark Ones can love their children, they can also be cruel to them. I might be wrong, but it's not the worst theory I've ever had.
