It is sort of unfortunate that the final two episodes seem to take place partially in some sort of fake version of reality, probably that was somehow written into a storybook. We saw the Evil Queen take the pen from Henry. We saw Henry write in the book after he gets it back. We see Henry get hit by a car or something, injuring his neck and arm in this other reality. We see the Black Fairy being the mayor and holding a storybook, talking to Gold, the Gold and son signs, Gideon in a dark suit.
Maybe Henry finds like the real storybook somewhere and runs with it and he is trying to get Emma to believe again, but she doesn’t and she leaves town or almost leaves town.
I mean that is not a terrible idea for an episode, but they have sort of done it before and if this is possibly the end of the show or the end of a lot of characters, it is too bad that they will be fake versions of themselves for it. Especially, right after the musical episode which will probably be utterly bizarre and feel out of character also.
