Itachi's Last wish.

Before Itachi died, he told Sasuke about everything. He told him how the Uchiha wanted to overthrow the Hokage, how he was ordered to kill the clan by the elders and that he loved the village more than the clan but he loved him more than the village itself.

He also begged him, as his last wish not to seek vengeance against the village and that he should protect it whenever it's in danger. He told him about the secret of the Sharingan and warned him about Madara and the Akatsuki.

He gave him different Uchiha scrolls full of jutsus and the 4th hokage's scroll of the flying thunder god technique. He entrusted him Shisue eye and told him how special the eye is and how it works.
