The Return is Kathryn returrning, but I believe August is Baelfire because TV shows don't believe in coincidences.
If August is Baelfire, how did he avoid aging all that time? That’s why I also believe he’s Pinocchio.
I finally believe he’s Henry’s father. I thought of it when rewatching episode 9. Of course Emma wouldn’t mention Henry’s father to Mary Margret if he wasn’t going to return some time in the series or in the same episode.
Also, aren’t the Brothers Grimm and Hans Christian Andersen dead and not fairytale characters. That’s just people who think it would be a good plot twist. Does anyone really August is them.
And the opening titles. They changed “Only one knows the truth” to “Who knows the truth?” Because now we know Mr Gold does too. And the Mad Hatter, ish, etc. They also changed “Only one can break the spell” to “Who can break the spell?” What if the Blue Fairy was lying when she said the tree can only hold one? Or she meant one fully-grown adult, so Pinocchio and Emma…
And that’s how August remembers.
