Sasuke runs frantically in search of Naruto. He flashes back to when he was 8. He had asked his brother to help him with a technique after school. Itachi had replied that he was too busy and that Sasuke should ask dad to help. Sasuke pouts. Itachi always treats him like a nuisance and never wants to spend time with him. Later, chibi Sasuke asks his parents if Itachi like shim. Dad says even he doesn't understand Itachi. It seems like he doesn't like interacting with people.
Itachi had always been talented. He graduated from the Academy at age 7 and became Chuunin at 10. He learned how to use the sharingan at 8. Sasuke remembers Aunt Shi*u telling him that if he was confidence in himself, he too, could one day be like his brother.
That day, Sasuke ran home from school to find Itachi crouched on top of a telephone pole. When he looked again, Itachi was gone. Chibi Sasuke notices all the lights are off in the village, but it's not bedtime yet, and starts to grow concerned. Then suddenly it dawns on him. The village has been attacked. He sees dead bodies everywhere. He immediately runs home to check on his parents. When he runs to the main room, he senses someone inside. He opens the door to find his parents dead bodies and Itachi standing over them. Itachi soon reveals that he was the clan's exterminator, and with his special Mangekyou Sharingan, he allows Sasuke to relive the day.
Sasuke is nauseated by the horrible scene he is forced to relive. He weakly asks Itachi why he would do such a thing. Itachi replies coldly that he wanted to see what he was capable of. Sasuke can't contain his rage and charges at his brother, only to be met with an uppercut that knocks the wind out of him. He falls limply beside his parents' bodies. Fearful, Sasuke's adrenaline kicks in and he takes off, running for his life. Anywhere will do, but he must escape his brother. He begs Itachi to let him live. Itachi is amused and exclaims that the boy isn't worthy of killing. His final words - If you wish to kill me, hate me, detest me, and survive in an unsightly way, do so. Run and cling to life.
Back in Shikuba town, Sasuke catches up to his brother, who has taken Naruto captive. He powers up chidori and runs, full of rage, at his brother. Itachi easily deflects the blow. Naruto taps into his Nine Tails chakra to defend his friend, but Hoshigaki uses his sword, Samehada, to devour Naruto's chakra.
Luckily, Jiraiya appears…
