This week we go back into the core mythology of Once Upon a Time: dark magic, Henry's twisted family tree, Hook on an adventure that is going wrong at every turn, authors, saviors and the revelation that we're on the last chapter of that Once Upon a Time book that started it all. We have so much fun theorizing and talking about what could be coming up in the next month, and wondering how all of those loose ends will be tied up. Could the entire series be wrapping up... or are we in for a dark curse to end all dark curses?
