I liked the chapter, but I did not expect Sasuke to change in 2 pannels. However, he was already changing a bit, proof of it is that he decided to wake up the dead hokages to learn about the truth (and not to use them as a tool to fight for himself), but most of us did not understand he was already developing because there was too much misteriousness and too little showing what he was doing in the previous chapters, Kishi should have shown more about how Sasuke decided to go to Konoha, or what he was thinking about, and then his change of mind would not have been this sudden to readers.
I predict that as soon as the group reaches the battlefield, everyone there will believe Sasuke is using the hokages against the alliance, he risks not been able to have a chance to talk - who would like to talk to him after his previous unreasonable behavior?
Only Naruto and maybe Sakura will be ready to belive about his change of mind. Naruto will remember that Itachi said that Sasuke is still very naif and can be easily coloured, and that may prompt Naruto to believe in Sasuke's change of mindo.
Oro, really... he has to be absolutely lying!!! His great aim in life is to become stronger, so I guess he's waiting for a chance to get Sasuke's and the Hokage's cells, and a bit of ten-tails, if posible.
