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.
Naruto might come across mementos from Itachi's childhood or his time with Sasuke. This could include old toys, letters, or pictures that would give Naruto a deeper understanding of Itachi's relationship with his family and Sasuke, and the sacrifices he has made.
There could be some sort of hidden passage or compartment in Itachi's room. Naruto, being curious, would explore it and find something unexpected like a prophecy or a key to an ancient mystery that is related to the balance of power in the ninja world.
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.
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.
One unique training method Itachi might use is teaching Naruto through illusions. Itachi is a master of genjutsu. He could create illusions that simulate real - life battle scenarios with various levels of difficulty. This would allow Naruto to practice his combat skills and decision - making in a safe yet challenging environment.
Another challenge is the secrecy that Itachi has to maintain in the original story. If he becomes friends with Naruto, how does he keep his true identity and motives hidden from the other characters in Konoha? Itachi is a master of deception, but Naruto is not very good at keeping secrets. This could lead to some tense situations where their friendship is almost exposed and puts them both in danger.
He might meet a mysterious old wizard. The wizard could be the one who brought Ash to the room, either for a purpose or by accident. The wizard could then guide Ash on a journey, or perhaps be an antagonist who has some dark plan for Ash.

Another consequence could be that it might put Bella in a difficult position within her family and community.

Jiraiya would probably offer some words of wisdom. He has a lot of life experience, so he might tell Naruto that crying is not a sign of weakness but a way to let out pent - up emotions. For example, he could say something like 'Boy, those tears are like the rain that nourishes the seeds of your growth.'
He could go on a road trip across America. Imagine Naruto seeing the Grand Canyon or the Statue of Liberty for the first time. It would be an amazing sight for him.
