In the Hokage tower
Naruto was on the couch, sleeping while the anbu that knocked him out and Hiruzen were talking.
"Sigh, Now give me a report of what happened," Hiruzen said with tiredness. ' Hai Hokage Sama,' the anbu said and started to explain what happened in the fight between Naruto and Sasuke, telling Hiruzen about the skills Naruto showed; he also explained that Naruto seemed to be in an unconscious state while fighting and about the attack on Iruka.
Hiruzen was shocked. He would kind of understand if Naruto had beaten Sasuke in a normal state, but beating the son of the Uchiha patriarch while unconscious with skills that far outclass him.
Hiruzen was thinking, "Could it be that he has a teacher, or maybe it was the nine tails controlling his body? Either way, I have to keep a close eye on him. Snapping out of his mind, Hiruzen looked at the Anbu, thanking him for the information and sending him off. The anbu bowed and shun-shined away.
Hiruzen got up and started to look out the window waiting for Naruto to wake up.
A few minutes passed and Naruto was finally waking up. Naruto sat up opening his eyes, seeing his grandfather figure standing looking out the window. Hiruzen turned around and walked toward Naruto sitting beside him. He asked with a calming voice, " Naruto, are you alright? ".
Naruto looked at him with a confused face and asked what happened saying that he could have sworn that he was about to fight Sasuke. Hiruzen then looked, thinking, " he doesn't remember".
Hiruzen began to explain to Naruto what happened and Naruto was extremely happy to hear that he flawlessly defeated Sasuke but immediately got sad hearing how he attacked Iruka. Hiruzen started to calm Naruto down telling him that it was fine and that Iruka would be fine.
He also started to explain to Naruto about how he would be training him over the three years in the academy so that something like this wouldn't happen again, but other than that he had another reason to watch Naruto he wanted to make sure that Naruto didn't have any secret mentors and making sure that the nine tails don't take control over Naruto's body.
Getting out of his mind he told Naruto that he could go. Naruto got up and ran off being sad about Iruka but also extremely happy about the Training he would get from His grandfather figure.
