Ok, so she never learnt that the child of Snow White and Prince Charming would be a daughter, yet in the Pilot Gold says to her “I would say you think you know exactly who she is.” That does suggest that she should know or at least has some clue who Emma is. And in the coming weeks/months Emma gives plenty of reason to suggest to Regina her true identity – she’s got an aweful lot to do with MM and so on.
HOW come Regina just doesn’t kill her off? It would solve all her problems?? Sure, no more plot for Once Upon a Time, but I still keep wondering. It would’ve been soo easy. She knows Emma doesn’t have any relations, etc in the rest of the world. Come ON, woman!
