I wonder if Patrick Fischler could return as Isaac for this episode? He did write page 23, and last we saw of him he was arrested by the Charmings. So heโs probably still locked up somewhere in Storybrooke.
I wonder if this means that page 23 is the original and her current story is the one that Issac rewrote…a theory that many of us including myself postulated and begged for an answer over ๐
Maybe the AU we will see is what should have happened if Isaac wasn’t in the habit of writing to control the stories.
