One possible scenario could be that Sarada is initially in awe. Meeting the Uchiha clan, she might feel a strong sense of belonging. She could discover new jutsus that were unique to the clan and passed down through generations. This would not only enhance her skills but also give her a deeper understanding of her heritage.
Sarada might be initially shocked and sad. She loves both her parents, and the divorce would be a huge blow to her. She could become withdrawn for a while, not wanting to talk to her friends about it.
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.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
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.
One possibility is that Sarada, being an Uchiha herself, would be in awe of Itachi. She might ask him about the secrets of the Sharingan, as Itachi was a master of it. Itachi could see the potential in Sarada and offer her some wisdom about the Uchiha legacy and how to handle the power of the Sharingan responsibly.
