how is madara going to pull this dilema off??
okey, it's obvious that obito is going to witness rin's death, this is probably a setup by madara and the zetsu's to make sure obito's biggest and strongest connection to the outside world is gone. might activate his MS or at least provide the emotions to activate it later (I'm also thinking kakashi used the feelings of loss of rin to activate his MS years later)
but none of that matters very much in this thread, what i'm wondering is how madara is going to convince obito not to revive rin.
I think this discussion is going to come up because at some point madara is going to have to tell obito that he plans to be revived by nagato's rinnegan. I'm thinking obito is going to aks why nagato then also can not revive rin. it looks like madara's death is close so there will be a lot of time until his planed revival, I'm sure obito will make to case to revive rin at this time, I wonder what madara is going to say to make sure obito doesn't do that.
