He let out a small scoff after Sasuke offered an explanation for the question. "You? Kill him?" It was impossible. He knew it better than anyone. Madara Uchiha was beyond the level of ... any shinobi. There was no possible way Sasuke could even touch him.
And again, Sasuke shared his revelation with him. Itachi had to give him some credit - he was smart. But no matter what, even if he showed up ... Sasuke couldn't go after Madara. He had to say something that would get a reaction from Sasuke ... something that would keep him focused on killing him.
"So you've figured it out."
But first came the truth. He shifted a little, turning further to glance at Sasuke, ignoring the pain from the sword.
"Uchiha Madara," he continued, turning back to sit in place. "The first person to ever awaken the Mangekyou ... and one of the founders of Konoha."
