Sasuke Pov
I was walking with Naruto back to the Uchiha compound when I saw dead bodies everywhere that is when I went running to my house with Naruto close behind as I entered and saw Itachi standing over our parent's dead bodies then I was about to ask Itachi what happened but that is when two kunai went flying by my head and barely missed but Naruto was not as lucky and get stuck in the chest.
I was frozen in shock, my brother just tried to kill me and Naruto was bleeding out but then I realized that meant he killed Mom and Dad in cold blood. That is when Itachi's eyes started to change and all of a sudden I was watching as Itachi slaughtered the whole clan one by one. I then somehow broke out of it and ran away with Naruto barely able to keep up with me.
Then Itachi appeared right in front of me with a cold expression on his face and said " l killed the whole clan to test my skills." Then I said In a scared tone "I don't believe it. This is unlike you brother." Itachi then told me that I and Naruto had the potential to become his opponents because we could unlock the Mangekyo Sharingan but there was one problem: you had to kill your best friend to get it. Itachi was about to walk away when he said "You are not worthy of killing. and one day, when you and Naruto have the same eyes as I do, come and stand before me." Then I started to feel tired and blacked out.

I was just informed by my root ninjas that Itachi had slaughtered all of the Uchiha so I went to steal their eyes for my gain that is when I saw Hiruzen had shown up also and acted surprised as if he didn't know what happened but that was expected since it was a top-secret mission. I then spoke with Hiruzen and said "It looks like Itachi carried out the original plan and got rid of the Uchiha. I told Hiruzen that the Uchiha would be a problem." Hiruzen then looked away and went to deal with other businesses. That is when I saw the knocked-out Uchiha boy that Orochimaru was talking about the last time I saw him. Then I came up with a plan to get him to join the root AMBU since Hiruzen would never agree to let me have him. So I was about to leave when one of my AMBU stopped and told me if I ever touched Sasuke he would pass on classified village information to every enemy nation and then he burst into crows and disappeared. I know it was Itachi because of his eyes but now my plan wouldn't work. I have to find a way to deal with Itachi so I can get Sasuke on my side.
