Knowing that even Itachi couldn’t exterminate the entire Uchiha clan on his own, Sasuke asks who helped him kill the family, planning to kill them too after he deals with Itachi. Itachi doubts that Sasuke can do it, but gives him the name – Uchiha Madara – the founder of the Leaf. Sasuke wonders how Madara could still be alive after so many decades. Itachi warns him not to be fooled by such facts, as Sasuke once thought of Itachi as a loving older brother. Sasuke, angry at Itachi’s condescending use of one genjutsu, demands that the real Itachi finally fight him. Itachi replies that until Sasuke gets his hands on the Mangekyo Sharingan there is no point in fighting him seriously, but nevertheless agrees to tell him about Madara Uchiha.
