And you're right that the author did not write the happy endings in storybrooke. He was already trapped inside the book by that point. Remember that they said that it was the Sorcerer and the Apprentice that were responsible for choosing the Author. The Apprentice imprisoned the previous Author, and my feeling is that the job has since been left unfilled. Meaning that either the Sorcerer or the Apprentice may very well be serving in the capacity of the Author until a new one is found. (Hence, all the blank storybooks in the Sorcerer's Mansion).

I also think that Emma being the savior is a little bit of meddling on the part of the Sorcerer in order to balance out what the previous Author did. Which means that if Rumple can fill Emma's heart with Darkness, then he can undo the meddling by the Sorcerer, which leave it open to redo the endings differently.

Just a thought.
