I read that the last 2 are spoilers. Yet When Rikage and Tsunade were running after the surgery, they spoke of the Shinobi Alliance. Rikage did have both arms and Tsunade did have her necklace. The discussion of the shinobi alliance seems to mess with the time frame.
Regarding the previous episode Finding Sakura it seemed like the 4th hokage was the spirit which possesses Sakura. I wonder if he will pop up again as Sakura is doing her job during the war currently. I am confused by this episode. Any feedback is appreciated!
