In the episode, A Curious Thing, Snow White has the crush Prince Charming's heart in order to cast the Dark Curse. After Zelena used a memory potion to make the all forget the past year in the Enchanted Forest, Snow asked Regina to split her heart in two so that she could share her heart with Charming.

Here is my theory, and yes it might seem crazy:

Does casting the Dark Curse require a whole heart or could it be half of a heart? To me, it doesn't state that it has to be a hole heart. So could it be half of the hear that belongs to the person that caster loves most?
