In this picture of Ven standing somewhere, which looks like the place where kairi sent her bottle out to sea, if you look at the bottom right of the picture, I see a figure that looks like Riku. However, I could also see the possibility that the shadow figure is Terra, but it fits more with Riku for me. What do you think? Maybe Riku travel back in time or it is just Riku as a little kid...idk( just making a guess) AND SORRY IF THIS WAS ALREADY MENTION, DON"T GO BERSERK ON ME.
Heres the picture
