If Zelena is Marian, why would she not turn back once outside of Storybrooke and Magic (ie In NYC)? Not saying that it doesn't happen, but I want a good explanation for that one.

Otherwise, Zelena being Marian this whole time is quite plausible. (and I hope it happens)

And, btw, we also know that Barbara Hershey is coming back for an episode. While I do not expect her to be resurrected, at this point I am going to say that nothing is impossible.

Which means, if that happens (which I doubt), we do not have just 3 queens of darkness, we have a whole flock. Can you even imagine the type of chaos that would abound with Cora, Zelena, Regina, Cruella, Ursula, Maleficenta (see what I did there), and Emma all running loose around town? And of course, every last one of them is going to want a piece of Rumple. Regina and Rumple described themselves as the strongest magic users in existence during the Neverland arc. Ironically, Zelena was revealed 4 episodes later to be stronger than either of them. The strongest to have ever existed. That kind of power can't be destroyed.

Magic seems to be an energy, and energy cannot be destroyed or created, it can only change form (something Rumple said about magic as well!) and it would be logical that the reason MOST magic doesn't work in the LWM is because magic gets converted into another type of energy while there.

Emma, Pan's Shadow, The Dragon and Walsh (powered by Zelena's magic), all most likely had enough magic that it couldn't all be converted. Safe to assume the same holds true for Zelena. She had just enough magic left over to keep the glamour spell that disguised her as Marian intact for six weeks in New York City.
