Very interesting chapter. I'm not too big on Orochimaru, but with him being physically back into the story for even a short time is good to see. I was really thinking about a weird, mystical entity being the one who knows all of the secrets, but I should've thought about this before (then again, you don't know with Kishimoto at times smh). With everything happening in this one chapter, Sasuke possibly having the Rinnegan could actually happen. Next week needs to hurry up. Also, did anybody else catch this in the chapter:
How clever Kishi...
