I actually kind of hope August is Pinocchio.
As for the aging thing? If Pinocchio was made of the same enchanted wood, couldn't it be possible that a glitch in the cupboard could have allowed both he AND Emma to escape? And he could be the boy on the side of the road AND Pinocchio in that case.
Exactly! Then he would have been unaffected by the curse. Also, Regina even says he seemed familiar, so she must have seen him when he young in the fairytale land, but now since he's grown up, she can't recognize him.
