The ninja tha was questioned by erosenin was talking bout how Pain/Nagato/God killed the salamander guy ( the vilage boss or smth) Ero was suprised ( flashback to a scene, when that guy, ero, oro. tsu meet ) He alaso talked bout how Pain killed that guys familly, frainds, clients and so on.

But there is one thing that is buging me, if Pain wanted to destroy any link to thaat guy, why didint he killed Danzou ?
