So if Naruto is so freaking awesome with the sage chakra why to heaven wouldn't have Jiraiya taken him to the big candy mountain or wherever he's training and dunked him in the oil during that two years we skipped way back when?? Eh. Anyway.

Gonna put money down and say that naruto is figuring out how to properly execute that rasen shuriken dealie he's got. Maybe the sage power lets him use the technique without giving himself cancer or whatever it did to his arm.

Dunno if Pain is attacking Konoha directly at this point. Its hard to tell what his deal is.
