That was a cool new development, I agree! Hopefully that hit Sasuke and Naruto landed on Obito didn't have an adverse effect on Kakashi through the link. We don't really know how closely they are connected--does it go beyond audiovisual?
Have to admit, if Obito is done in by this, then I'm gonna be pissed. That being said - I would not mind maybe one or two 'AU' pages about what life would have been had Obito chose to remain in the village. I don't know, maybe Obito casts the Tsukuyomi on himself and wants to die 'happy' or some cliched out of character BS like that....
That being said, if Kakashi dies in the next few chapters. Lost-y be very pissed-y.
I'm chuckling at the expressions on their faces!
