There’s so much we don’t know at this point but was nice to have a few things new to mull over.
I don’t know about the potion/talismans/gurney business but I know it sounds like Wicked is going to be an antagonist to Regina, and guessing our other main characters will likely be on Regina’s side or caught in crossfire. I don’t think Wicked is shaping up to be “misunderstood” any more than Pan or Cora. Pan’s ambitions were kind of narrow when you think about it, despite the scale of his operation. All he wanted was to live forever and fly. He wasn’t exactly planning world domination or something.
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
