In an article or in a blog someone mentioned they thought Cora taught Regina magic to the point Regina got more powerful and got rid of Cora.
I do not think that has happened, instead I think Regina learned her magic from Rumple, but she learned behind her mothers back. I do not think Cora would have taught Regina anything. Cora was all about POWER, if she taught Regina magic she would loose the power over her.
Instead Regina learned from Rumple making whatever deals she had to in order to get magic. I think Regina was desperate enough to try any method or means fair or foul to break away from her mother’s power. I think she did it without anyone else knowing. Regina may have gotten rid of her mother either killing her and becoming evil or more evil since I think she always had it in her. Or she banished her mother to Wonderland, stealing her magic from her mother making here weak.
Regina learning / dealing with Rumple would go far to explain the relationship and knowledge she had with Rumple.
Any thoughts from others on my theory would be welcome.
