before we all go and say the August is Pinocchio, Peter Pan or [insert other relatively minor character], remember that he came from outside Storybrooke. People can’t leave, at least not until the Curse is broken. If they can’t leave they can’t come back, and he clearly came from otuside the town.
Anotehr blow to Pinochio Pan, He would need to be either ten years old or near his fifties. We saw Pinocchio in the pilot as a ten eyar old and Pan can’t be too far behind. Even if Gepetto, Tinkerbell or [insert other relatively minor magical character here} made a loophole, they would nromally age as Emma did.
