hmmm do you understand what sakura was brabbling about in the end "so... when you open it in the middle.... sai... and his brother..." <------- ???????? yaaaa sai and his brother????okaaay......what?
at first i thought she was going to say you could start reading it in the middle, but that doesn't make any sense..
edit: ah btw about kabuto being sai's brother, thats actually a pretty good guess.. hmm if you look at 15:10 isn't sai is focussing on kabuto there?... hmm maybe in episode 45 he does the same, i ll take a look
