I really liked how this chapter began via Orochimaru & co. I liked that Kishimoto shed some light into Katsuyu’s origin. The Shikkotsu Forest may also possess a slug sage and the reasoning behind Tsunade never having mastered a Sage Mode could have been because of changed beliefs via Dan & Nawaki’s deaths. For so many that have claimed Tsunade to be useless or weak were very much corrected in this chapter as the woman was severed in two and still surviving. Its too bad that her old face wasn’t shown but I suppose Kishimoto did this as a homage due to her self-consciousness.
Karin/Suigetsu/Orochimaru were all amusing. I was shocked at Orochimaru’s approach. It appears as though he truly has begun to change as he could have rather taken advantage of Tsunade’s weakened state and attempted to kill her. Orochimaru has come to see Sasuke in a different light which provoked this change and seemingly holding him in high regards.
Concerning Sasuke’s actions in this chapter, I think could be rationally explained. While many may continue to think that he is scheming and never actually changed, I disagree. In my opinion, I think that his decision to refuse Naruto and allow the black flames to continuing burning was due to wishing for an end to the tailed beasts which if anyone would stop to think for a minute and remember that he doesn't know of the tailed beasts changing. Thus he believes that they are all still malevolent and this was his chance to eliminate them once and for all. Sasuke in my opinion even though I am saddened to say is seemingly becoming more like Danzou as he is choosing to implant his own ideals rather than maintaining an open mind. I'm pleased that even though Sakura may be a little doubtful of Sasuke that she is choosing to believe in him and Sai’s continual suspicion I think is Kishimoto’s way to obscure Sasuke’s revelation.
The Kaka/Obito entry was out of nowhere and insane as it seems as though Kishimoto may want to end both their lives. If this is true or if only Obito dies, I hope he changes and revives everyone he killed.
