Actually, a thought just occurred to me. Did the Sorcerer and Apprentice choose a new author after they imprisoned the author we just met? We don’t even know if the author even still has his powers, because his quill was taken away by the Apprentice. Maybe August knows all of this information because he was secretly chosen as that author’s successor? As for why he’s not telling Emma and company this information, he may have his reasons. But yeah, August being chosen as the succeeding author would explain so many things. Yeah, I know this theory might have its holes, but I thought I might as well suggest it.
