I know this is a weird theory, but I had a thought about Fujitora's scar.
What if the person who gave Fujitora his scars that made him go blind was also the person who cut of Z's hand, namely the unnamed 7th warlord. Tell me what you think!
Do you think it would have been better if Kishi didn't put the kakashi backstory at the beginning of Shippuden but he introduced the flashback right after the Tobi reveal?
