I thought the paths of pain were ninjs that jiraiya met on his journeys. . .
although I never understood the point of that,
and yeah danzou does look more like madara especially with his eye patch but it still wouldnt make sense
i mean he could have just taken narutos kyubi a long time ago, and the whole thing of danso ordering black ops to spy on the uchiha. . .
but that eye patch. . .damn kishi. . .just show us whats behind tobis' mask alredy
