But didn’t Cora say that she had to make a ton of deals in order to gain what she had? And since it’s been confirmed that Cora is the original miller’s daughter, something tells me that she made those deals with Rumpel. The only thing of any real value that she possesses is magic. Yes, she a large estate and lots money, but Cora said herself, power is the only thing that lasts. I think she made a deal with Rumpel to gain her powers.
And I think killing someone powerful in order to obtain their powers only applies to the Dark One. What about the fairies? What about Jefferson? And what about Emma’s magic? She didn’t have to kill anyone to gain her magic. So far, the only person who had to kill in order to obtain their powers was Rumpel. I think that’s a trait that only applies to the Dark One.
