@ zeroLT It's not killerbee we're talking about
Probably gunna happenI think that Konoha will fight off pain ( not kill him ) with many losses of unknown shinobi and 1 loss of a shinobi known to naruto so that he can take it personally.
Think Danzo will feel the grunt of Konoha's hate towards Naruto not showing up. Imagine Naruto finding out it was Danzo who killed the toad messenger + it'll be a double blow for him 1, Danzo killed one of his contract animals 2, Danzo was responsible for him not being able to save his friend.The people of konoha will question /blame him for not coming to konoha as pain was after him afterall. Naruto will feel like shit. at the time naruto returns will be the time i think sasuke will reach the leaf village and will try to kill the elders ,with the truth about the uchiha massacre coming out....
If Sasuke shows up then both of them will hate the Elders with a passion.... Thats gotta test his loyalty, or at least start a brawl with the elders.
