I think that the Wicked Witch is Cora and Rumple's daughter, and was the "unnoticed" child, unlike Regina, who was the main focus of Rumple, Cora, Daniel, Valet, and everyone else. I think that she wanted to be loved so badly, like Regina, that she was willing to do the unthinkable, meaning she probably became green to gain power in order to earn her mother's respect and love. Even though she couldn't because her Mom chose not to keep her heart inside of her.
