I just posted this in the thread Regina and the Queen of Hearts:
Ok, crackpot theory:
In the Through the Looking Glass Alice becomes Queen for a while. I still don’t think Grace will be Alice and even though I like Emma being a kind of Alice, it would be cool to have the character on the show. This theory works with Alice being Jeff’s wife or not. The timeline of the original story (the books) doesn’t necesseraly have to be the same on the show (it’s Kitsis and Horowitz after all).
My thought is, considering the fact Alice became a temporary Queen in one of the books, that she became the Queen of Hearts.
Now, I can’t think of anything really supporting this theory, but I think it would be great twist on the story. 😈
