Tobi stands in front of Sasuke.
Tobi: You can ask whatever you want, Sasuke. Be certain that I'll answer every question, solve all your doubts...
Sasuke shakes his head.
Tobi: Well then. If you don't make questions I'll start.
Tobi: As you know, your brother was one of my students. A talented one I must say...I kept my eye on him sice he started the academy. I waited for someone like him all my existence...
Sasuke coughs a little blood.
Tobi: Lay down Sasuke, you need to rest.
Tobi: Well, I knew he had talent, very much talent. I decided to develop his power, but to reach it he needed the extreme sacrifice.
Sasuke: Killing his closest friend?
Tobi: Exact. Now...it's a little long to explain it by words. Let me show you some of my memories.
The sharingan under the mask starts rotating fast...
Sasuke is now looking at Tobi with a young guy.
Tobi: Now boy, you completed the training . I've done everything that I could for you. Now all depends on you. You know what must be done, right?
Sasuke: Is this......genjutsu?!
Tobi stands behind him.
Tobi: Yes, I'm showing you the most important steps in Itachi's life. All starts here with little Shisui.
Sasuke: Shisui!!? Itachi's best friend!
The illusion goes on. Tobi now is facing a young Itachi.
Tobi: Well done Itachi. Now you must complete the last step.
Tobi: and now Sasuke, the most important.
Itachi and Shisui are walking at night in the forest.
Itachi: You wanted to see me? Shisui-san?
Shisui: I must show you one thing. Come, this way.
They walk a little more. Then stop in front of the hideout Naka near to the river Naka.
Itachi: Now what?
Shisui: Forgive me Itachi..
Itachi activates the sharingan
Shisui disappears and pierces Itachi with his kunai.
Shisui looks at Itachi. He is no bleeding.
Itachi appears behind him.
Itachi: What do you think you are doing?
Shisui: I'll kill you Itachi! It must be done, to achieve the ultimate power!!
Itachi: It...you...you have been training with Madara too!
Shisui: What? You know about him? He never said me...But it doesen't matter. He gave me a test and I'll complete it!
Itachi: Do you really want to follow his advice? You really intend to kill me for the superior sharingan?!
Itachi: I don't want to hurt you, but if you force me to defence I will kill you.
Shisui: Katon! Ryuuka no jutsu!
Itachi avoids it.
Itachi: Kage bushin no jutsu
10 clones appear.
Clones: Katon! Housenka no jutsu
Shisui uses his body flicker but the real Itachi manages to catch him and they both fall into the river strangling each other.
Itachi: Shisui stop it...
Shisui is losing his senses. The water calms.
Someone jumps out of water. It's Itachi with Mangekyou sharingan.
Tobi: Good Itachi. After all you were stronger than Shisui. Now I can tell you all about my true plan! For an even greater power!!
Next time: the sorrow of that day.
