One possible scenario in this fanfiction could be Fugaku seeing Sarada's potential and taking her under his wing to train her. He might recognize her Uchiha blood and want to ensure she becomes a strong shinobi like the Uchiha of old.
Itachi would probably be very calm and composed. He might see Sarada as a symbol of the new generation of ninjas in the village. He could be gentle with her, perhaps sensing her potential and her desire to grow as a ninja.
In a Sarada meets past Sasuke fanfiction, it could be that Sarada has to keep her identity a secret at first. She might be on a mission in the past for some reason. As she observes past Sasuke, she could notice his skills and the way he interacts with others, like Naruto. This would give her a chance to understand the bond between her father and Naruto from a whole new perspective, which could be really interesting for the readers.
In a fanfiction where Shisui meets baby Sarada, Shisui might be feeling a bit melancholic as he has seen so much turmoil in the village. But when he sees Sarada, he feels a glimmer of hope. He may hold her gently and think about how she is the future of the Uchiha clan. He could even vow silently to protect her from the shadows, just as he has always tried to protect the village.
In the fanfiction, the interaction between Sarada and Sasuke's family could be filled with emotions. Maybe Sasuke's family has high expectations of Sarada, given her relation to Sasuke. This could create some tension at first, but as they get to know her better, they start to accept and love her.
It would be a moment full of anticipation. Sarada, with her hand on her kunai, ready for any threat. Madara, standing tall and imposing. The air around them would seem to crackle with chakra. Sarada's Sharingan would be activated, trying to predict Madara's moves. Madara, on the other hand, would be smirking, amused by the young Uchiha's bravado. Their first words to each other could set the tone for the entire encounter, whether it be one of hostility or a begrudging respect.
Itachi's skills and wisdom would no doubt rub off on Sarada. His combat expertise and his way of thinking could give Sarada new ideas on how to approach battles and solve problems. This would make her a more well - rounded and formidable ninja, thus contributing to her growth in the ninja world.
At first, it could be a bit awkward. Sarada has only heard stories about Itachi. But as they start to interact, they might develop a mentor - mentee relationship. Itachi could see Sarada's potential and start to guide her.
