I think we’re missing a very improtant question in this whole equation. What KIND of magic does Emma have? Her magic stems from two possible sources. The true love of her parents that brought her into this world, and Rumpel’s magic, that for some reason chose her to be the key to breaking the curse. Rumpel has given her some type of magic that helps break his dark curse. Why? I think she has elements of good magic in her, and elements of dark magic in her.
