The whole 'since I've mastered nature energy I can detect chakra bit' was OK, except the fact that Naruto never saw Kakashi *after* he 'mastered' it. I suppose we are to believe that he can just tell what kind of chakra Kakashi has, or this whole time he has been subconsciously aware of everyone's chakra?

Other than that, nice to see him kicking ass for once. Finally he turned his wind shuriken into an actual shuriken. He should be able to use that even without Sage mode, I hope.
