Ok sorry bout starting the fan fiction spam but time to stop
Who thinks its the real danzo?
I'm torn. As I've said before, I
sincerely think that Danzo will not die here. Likewise, we all know that Sasuke won't die here either.
Or, Sasuke could die and be resurrected. We have seen more than one resurrection jutsu used in this series. Regardless, we know Sasuke is going to make an appearance in the series finale, so he isn't dead "for good" here.
Do we really think that Danzo would go all-out against some young punk, when Danzo has nothing to gain from this encounter? Why would he risk his death here, now, against Sasuke? It makes no sense and I think it would be lousy story-telling from Kishi to do it.
Danzo has mokuton still, which he's barely used. He has his bandaged right eye that has yet to make an appearance. He has that whole face on his shoulder that he hasn't used yet. Seriously, what does that face do?!?! He can't die until we know that much.
I don't think we've seen the end of his tricks. And that's just it: Danzo has too many resources available to him, he isn't going to just get stabbed in the chest without some kind of defense or backup plan. He's not going to just die for no reason.
I bet this is a genjutsu from Danzo. I think his right eye has finally recharged, he's cast a genjutsu, and by the time Sasuke realizes it Danzo will be halfway back to Konoha.
