What an amazing chapter. Orochimaru crawls out of that snake like nothing ever happened and continues to be a total boss. I just love him. And I like how this is going. Orochimaru being revived gives the plot an unexpected twist, and with him being back on the scene there are going to happen even more unexpected things. Orochimaru will mess up everything. <3
However, I thought Orochimaru wasn't able to master Sennin Modo? Then how is it possible for him to infuse the Juin with Senchakra? If he really would be able to use Senjutsu he'd become even more of a badass than he already is now. Also somewhat incredible that a part of Orochimaru's consciousness resides in each and every Juin. What also bothered me a bit was Sasuke just creating a technique to loose it like it was nothing. In order to seal it, Kakashi had to do preparations. Sasuke, on the other hand, wasn't even known for knowing any Fuinjutsu, and now he's just pulling one out of his sleeve like it's nothing? No, that was a bit noncredible.
But those things are bearable - Orochimaru is just an incredible, truly immortal being, and Sasuke extraordinary skilled. As for 'them', the ones Sasuke wants to meet, my bet is on Rikudo's sons. After all he wants to know everything - what a clan is, what a village is and what a Shinobi is. All in all how everything began - and it all began with Rikudo's sons. They were also the ones to start the chain of hatred.
Now, I wonder where Orochimaru wants to go with them. To one of his lairs/hideouts/laboratories? Or would that be too obvious? He might be talking about Konoha or Tobi's hideout as well.
