Re: 513prediction /spoilers
513 is probably going to be a dumb filler chapter, With gaara and kabuto heading towards the island. Then cut to madara and zetsu conversation of " should we trust kabuto...blah blah blah. and then probably some convo between Naruto, Kirabi, and yamato & co. about what they should do to prepare for an enemy attack. 514 will probably have gaara and kabuto arriving at the island.
