A fan figured out a way that August could be Baelfire regardless of how many centuries have passed after “Desperate Souls”.
The writers of Once Upon a Time have been known to use stories that aren’t your typical fairytales, but still have Disney films made about them like Pinocchio, Alice in Wonderland, etc. What about Peter Pan?
What if Baelfire managed to end up in place where Rumpelstiltskin may have not been able to retrieve him for some reason? A place like Neverland. Baelfire could have been one of Peter Pan’s lost boys. It would certainly put a new spin on the phrase, “I lost him.”
We all know that people who find themselves in Neverland never age. It is possible that Bae could have somehow escaped the curse and found himself in the real world as a 14 year old boy.
