Great and sad chapter. I was about to curse kishi for not using ObiRin as a NS parallel directly to Naruto until I saw that he tried to heal Obito with his palm. Naruto was using his chakra to heal Obito, which obviously had failed. However, I believe what i'm about to say is not a theory but a legit reason behind the OR flashbacks have been seen by Naruto once again.
Flashback to the point where he shared with the alliance Kurama's chakra cloak. Chapter 652 was the tugging between Obi and Naruto's chakra.
He has the ability to sense peoples feelings and memories of that feeling when his/Kurama's chakra intertwines with another person's. And the people who has chakra cloak on them can be allow access to his feelings and the memories that comes with it. Everyone on the battlefield saw Naruto's past (forgot which chapter).
Today's chapter shows him morning, despite Kakashi mimics his posture and despair here.
Chapter 652 backs that up where he also shed tears here.
Overal, ObiRin is now officially canon. R.I.P ObiRin
Despite being a criminal, he was manipulated, so i'll go easy on him. If NS does become canon, Obito is my MVP pick.
So who gives a f*** what SS and NH fans says?
