Perhaps Naruto sneaks in to confront Itachi about Sasuke. He wants to understand Itachi's actions towards Sasuke better and hopes to find a way to prevent Sasuke from going down a dark path. He might be shocked to find Itachi in a vulnerable state, different from the all - powerful image he had of him.
In some fanfictions, Naruto might be searching for some crucial information about the Uchiha clan. He could stumble upon Itachi's personal diary and learn about his true motives and the secrets he's been keeping from everyone.
He could find Itachi's collection of jutsu scrolls. These scrolls might contain rare and powerful jutsus that Naruto has never seen before, which could give him new ideas for his own training.
In the fanfiction, Naruto could be sneaking into ANBU to prove himself. He might think that if he can infiltrate this elite group, he'll be seen as a true ninja. Once inside, he could encounter some old friends or foes who are also part of ANBU. He'll have to use his wits and skills to avoid getting in trouble. He could also discover some new jutsu or training methods that the ANBU use, which could help him in his future battles.
One possibility is that Sarada, being a young and inquisitive ninja, would be in awe of Itachi's skills and reputation. She might ask him for advice on becoming a better ninja. Itachi, in his calm and wise way, could offer some insights on the importance of self - control and protecting the village at all costs.
Well, in the fanfiction world, it could be that Percy is on a mission. He sneaks into Annabeth's dorm to find some important item related to their next adventure. He might search through her bookshelves or drawers carefully while trying not to wake her. If she wakes up, she could be initially shocked but then understand when Percy explains the situation. And they might end up planning their next move together right there in the dorm.
One thing that could happen is that Naruto's influence might make Itachi more open about his feelings. Itachi has always been a very private person, but Naruto's outgoing and empathetic nature could break down those walls. They could also combine their abilities in combat in unique ways. Naruto's Rasengan and Itachi's Fire - Style jutsu could create some really cool and powerful attacks.
One possibility is that Snape has a secret mission related to Hermione's safety. Maybe he discovers a plot against her and sneaks in to protect her without her knowledge. He could leave some protective charms or a note warning her.
Well, Naruto might be shocked at first. He'd probably notice the resemblance to Itachi right away. And then he'd start thinking about his own relationship with Itachi.
One possible outcome is that Naruto, being in Itachi's place, might have a very different approach to dealing with the Uchiha clan situation. Naruto is known for his strong belief in redemption and friendship. He could have tried to reason with the Uchiha clan instead of the events that Itachi had to go through. This might have led to a different relationship between the Uchiha and the village.
One possibility is that Naruto could try to change the Akatsuki from within. He might use his positive attitude and strong will to influence the members. For example, he could try to convince Hidan to give up his brutal ways, or persuade Kisame to question the Akatsuki's more extreme goals. Since he has a connection with Itachi, Itachi could act as a sort of protector and guide for Naruto within the organization. Naruto might also learn some new and unique jutsu from the other Akatsuki members, which could change his fighting style.
There could be a situation where the inn is under attack by a common enemy. Itachi, Sasuke and Naruto have to put aside their differences and work together to defend it. They use their unique skills - Itachi's genjutsu, Sasuke's fire - based jutsu and Naruto's shadow clones - to fend off the attackers. This experience bonds them in a new way and they leave the inn with a newfound respect for each other.
