I know some people are dedicated to the idea that August is the real boy, but it would be a let down if so. Just because you don’t see much of a development from Pinocchio. Pinocchio was only seen in the pilot twice. I was hoping that August would be that boy that found Emma when she was a baby on the streets, but IDK. If August is Rumpel’s son then that would widen the plot/conflict a bit to many more possibilities. It would be awesome too and you’ll see a deeper side of Mr. Gold.
However, the writers may just be teasing us as always.
