On the subject of where Gara is headed, I only see two options. Both could be related to what Kurama told Gara.
A. Finding Minato - this would be the most obvious option and whatever possible plotholes that might arise could be explained away by Minato himself, or if Minato can't do anything, maybe Naruto actually does die and Obito uses the remainder of his lifeforce to revive him. Then we get the Obito/Rin parallel with Sakura present and a Naruto's death scene with Sakura
B. Tomb of the Sage of the Six Paths - instead of just to a remote location to recuperate, which would negate the conversation between Gara and Kurama, maybe there is some connection that could be made to the 6 paths and revive Naruto, maybe we finally get to meet the sage himself in one form or another - this option would be less obvious but cool
I like the previous posts saying that Naruto might meet Jiraya. That too would be very cool.
My only problem with the current situation in the manga is that Bee's state has not been addressed. He is not an Uzamaki, so is he already gone?!
And finally, seeing as how I am a long time NaruSaku supporter, the coolest part of all is that when the next chapter is released, I will be in Japan for the first time.
Coincidence, I think not!!!
I think Killer Bee's whereabouts will be addressed in the next chapter, if not then it'll happen sometime in this volume.
