Thanks for explaining the flashback scenes. I will go back and read the manga in which these scenes are from because I am wondering a bit about Danzo's use of Izanagi to survive, as CJ Mac stated, and whether he may resurface later on.
I am also wondering about the many ".........." Sasuke is shown having in manga 587 as Itachi's is explaining how Izanami/Izanagi works. As I read 587, specifically at the end with the Kabuto scene of his orphan brother still waiting for him to come back (9 o'clock), I notice a parallel with Naruto still waiting for Sasuke to return. I also thought about, and am wondering, if Itachi is trying to actually help Sasuke make a "decision" while trying to get Kabuto to make a correct decision while trapped in Izanami.
