I hope so. There’s so much mystery around him like how did he get out of the hat? How did he know about the basement? How did he know Belle was down in the dungeon and to send her to Mr. Gold? That means he knows the tale of them and Regina’s part in it…… Wait! Jefferson said he watched Grace/Paige even when we thought he was in the hat. Can… can Jefferson see everything? And in that case could he have written the book. Just an idea, though I still subscribe to the Blue Fairy theory.
