why did they add in the "unless senju's chakra" part?
the fact that the uzumakis are senju decendants, trees growing on shit when fox chakra naruto has been touching them, I am almost certain it will come to be that Naruto has some sort of diluted version of Hashirama's chakra for the sake of plot. I guess that depends on what happens to that crow though, if it will end up being stored in naruto again once this is all over. I am sure Itachi will find a way..
