naruto's new found powers seem to be the best possible answer to this situation with the zetsu's so I hope we get something like that comùing up.
and about katsuyu, the pannel your talking about on page 14, it may look like that's what he's thinking about but in fact it is not, she is just on his desk, and the proof is a couple of pages befor that page, on page 12 of this chapter we already see katsuyu sitting on the desk. and if I'm not mistaken it's the first time we see her during this war. in my oppinion tsunade summond katsuyu right befor she and the raikage left to intercept Bee and naruto, and she did this with communication in mind, so that there is always a direct line of communication between them and the HQ.
