Re: Madaras dead, but lives on!
I don't like to include Danzou (Mostly due to him being a complete whore). But, to keep the substance of the thread going.... I could see someone trying to put a co-op between them. At that time the Forth had been chosen and Danzou could have been looked over again. Even more so that Danzou beleives that the village needs to be "Reborn" in order to thrive (Load of crap).
Now the shell of his former self.... I still don't think that this statement fits with the situation your trying to play out. I think Itachi might have said something a little different if it wasen't madara, then again it's not like there are pictures on display to let everyone know what these people looked like.
