For those who don't like Sasuke, even though he's in this chapter, from the spoilers, it appears it's more about Karin and Naruto. I don't mind Sasuke, but it's been a long time. Why?
A.) We finally see some combat ready abilities she has, such as the vampiric like healing. I find it kind of wierd, but it's unique. I wonder if she had it before she met Orochimaru or if this is one technique she got from him. We finally are going to start seeing team Hawk, and not just team Sasuke.
B.) Supposedly there are 4 pages related to Naruto's training.
3.) Naruto is not coming back to fight Pein until he finishes his Senjutsu training, or he is going to die, be captured, or go beserk (4tails) and destroy Konoha. If he is not supposed to move, but be patient and sense nature in a meditative way, that should tame him some. Rather than flying into battle or getting angry, I believe he will start to think about things first. Jiraiya wasn't the strongest of the three Sannin initially, but I think he may have ended up that way. He learned to make his own jutsu, and Naruto will complete the ones left for him. Namely wind release shuriken rasengan, the frog seal jutsu, which probably can go so far as to remove the seal, a more diversified and controlled summoning capability, and start to make his own jutsus.
In order to control the 9 tails with a weaker seal I expect him to use nature's chakra. The bijou's are chakra monsters that occur in nature, thus it seems logical that nature chakra infused with his own could control the Kyuubi inside of him.
4.) Except for Temari, Ten Ten, Hinata, and maybe another Kunoichi, they are all capable of medical jutsu? That seems kind of biased.
5.) Naruto should use his shadow clones when things are explained to him, since if he doesn't get maybe Naruto 884 does, and then he recollects them.
6.) Where did Kisame and Madara go? I have a feeling Zetsu is watching the fight between Sasuke and the 8 tails. Further, he's probably reporting to Madara what's going on. Karin hasn't sensed him, but he's a spy, so he can probably avoid that.
7.) Madara was certain, or at least said so, that Sasuke would defeat the 8 tails. I wonder if he sent Sasuke there to awaken or force Sasuke to use his MS more in order to defeat the 8 tails.
8.) One last thing. If Naruto marries Hinata, it will make changing the fate of the Hyuuga clan much easier, and leave one hell of a blood line.
Thanks
