I liked the chapter, it filled in a lot of holes. I guess BZ considers Kaguya his mother since she created the Zetsus. Sasuke was speechless and I can't blame him after realizing that BZ rewriting the tablet is what caused the extermination of the Uchiha. Madara was played from the very beginning, even before his fight with Hashi. The presence Hashirama felt at VOTE was BZ.
Kaguya crying over her sons shows that TNJ might be of enough help to enable them to seal her. According to *********** and Manga Bee she wanted the chakra to give it to her two sons, she had to have loved them very much to want them to have all of the chakra. I guess her love turned to hatred when they sealed her. She went from wanting to give them chakra to wanting to take it back from them.
Also Tobirama was not mentioned in either *********** or Manga Bee. I guess we will have to wait for Viz on Monday. Still some questions left though. What happened to Hamura? Did Naruto heal Obito when he picked him up? Is Madara totally gone, it seemed as though he blew up, or is he somehow inside of Kaguya? Will Madara's will have a hand in defeating Kaguya or was his will all just BZ's will?
