This is just a little thought not a prediction about obito's story that I would have liked to see. With obito being considered a bit of a loser outcast in some respects with none of the kids his own age wanting to hang out with him. It would have been cool if kishi showed him hanging out with the littler kids telling them stories about his adventures saving his comrades. It would have been neat to see a young itachi listening to him starting him on the path of what he believes in.
Again just a thought not a prediction
Would like to hear other ideas people have about what they would have liked to see
