As you may know (sometimes) between chapters you'll see artwork showing off things such as naruto riding a frog. But if you can see this it is on the first volume but he doesn't ride or control a frog by volume 11 NOTE: I'm only going up to volume 11. Even if 12 has been read or not we'll not go on from there to avoid spoilers but you also see Sasuke by a snake and Sakura by a Slug! Could this be a clue to a seperate later story also I saw one with Kakashi without his mask! But covered by the bed sheets he was sleeping in and also you see him with his students in a picture and beside THAT picture you see a kakashi looking child with his mentor and a young girl in the middle with a boy to the left Gai? Or the girl Tsundae(sp?) and thats it tell me if you seeany so called "hints" post them here.
