I hope that Sakura gained the respect of some of her haters this chapter. This is the definition of not being useless. This is the definition of a true amazing medic nin. Cutting open someone's chest and pumping someone's heart manually.
Now the arguments will probably be that medic nins are useless overall though I'm sure.
It's definitely Yamato behind that spiral Zetsu. I'm PRETTY sure about it.
I was kinda surprised by Karin's new abilities. I'm going to assume that many Uzumaki's had that, which was one of the reasons why there were feared and now virtually extinct. Having the rare chakra of an Uzumaki in your hands appears to be a treasure.
I think the mysterious dirty feet by Sasuke is Kabuto. Who else could it be?
I'm so worried about Kakashi and Minato... Madara is going there next.
I didnt hate Sakura. But too bad Im just rooting for the other side. (Hinata) In this Chapter, Sakura is trying all her might to save Naruto, but I guess she will also do it for the other fellow Ninja. Im quite agree of the other speculation about Yamato & Kabuto though.
