A curious thought might be this: Henry said that Frankenstein wasn't in his book (for obvious reasons.) So would it be possible for there to be other books concerning the stories that happened in the OTHER worlds? This clearly isn't the story Mary Shelley wrote as it diverts greatly from the original novel. However, I myself find it doubtful that there would be another book of its kind. So my questions to you are:
1. Do you think there might be other books out there about the worlds we saw in the Portal of Doors? (When you think about it, Henry didn't know about the whole involvement with Frankenstein back in the Enchanted Forest and frankly, neither did the rest of the town. So who knows what other characters from other worlds ended up there that weren't in the book that Regina wanted from somewhere else? Were there other lands behind the doors that weren't in the book?)
2. Some of these stories are clearly a bit more...shall we say "newer" than others, so how do you suppose these new worlds come into being? Did the authors simply create the worlds through the books, thus birthing new worlds? OR did the authors visit these worlds and simply write them down?
3. Why do you think whoever wrote the OUaT book decided to do so? Were they hinting to something? Or were they subliminally trying to reach out to Emma and wound up in Henry's posession instead?
What do you think?
