So now we are in chitchat/flashback (in a flashback :P) mode. So would you like it if it lasts for 10 chapters? 5 chapters? Because right now Kishimoto is trapped again. He can't go back to the fight because then he will have to stay there for many chapters. I guess it depends on what the "history class" will be about but still some people can't wait to see what happens in the battlefield.
