Sage Mode???? Hmm, this chapter had its ups and downs, but I'm so over Obito. His redemption is too little too late; but redeemed nonetheless I suppose. So while Hagoromo was the first to unlock the key to Ninjutsu, his mother truly was the first to use chakra as a weapon. It's also interesting to learn about the original intention of chakra.
It appears we all may have jumped the gun, and that Naruto will end up with the Yang half after all. In fact, Obito may be reaching to pull the Ying half out of Madara as well. So that leaves one hero, but the other may still be in trouble (Until we find out the mysterious figure really is Kabuto there to help lol I mean Obito was just redeemed, so Kabuto falling next in line wouldn't surprise me.) I have to admit, I'm still hoping Madara is just messing around with Obito, and that he will fail in attempting to get the two halves over to Naruto. If that does happen though, it undermines Obito's words and actions.
Oh wait a minute! Minato is the only one who can perform the seal anyway! Unless Obito or Kakashi magically knows this Uzumaki seal. I didn't think much of it before, but now that he has lost his other arm, he can no longer seal either half of Kurama inside of Naruto. I have my doubts that anyone else could perform the seal though, except for maybe Orochimaru or someone who knew of the Uzumaki clans sealing techniques. Orochimaru and other possible applicants are busy with other things however. If anyone though, it'll probably be Obito since he has done similar things, and it will further his redemption.
PS: Uhh..Did Obito just make his hermit staff manifest?
