What if instead it has to do with revealing the “boss” of whatever curse comes next? We assume it is about New York, and Neal, but it could be about say characters we have not yet met. I like the idea though it would contain some backstory on Neal, and how he got to NY, along side some story of how everyone tries to get somewhere (Emerald City in Oz?!) that has a similar lure to it.

“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
