I just sent this into the podcast, but this is what I said in regards to this…
I do think that the Sleeping Beauty storyline with Mulan that occurred during this episode is not the same as the traditional one we are used to from Disney movies, etc. I actually like the idea that this Aurora is the actual Sleeping Beauty’s daughter. The one piece of evidence I have for this goes way back to Season 1, Episode 2. During Regina and Maleficent’s scene, they say…
Maleficent: “Weren’t you about the same age when you were to be married before she (Snow) ruined it all? Yes, you were.”
Regina: “Yes, it was about the same age you were when that Sleeping Beauty got the best of you, my dear Maleficent.”
Based on Regina’s line, it sounds like the traditional Sleeping Beauty story had already happened when Regina obtained the curse.
