Well, Itachi might be shocked to see how much Sasuke has changed in the future. Maybe Sasuke has developed new powers or a different outlook on life. Itachi could also feel a sense of pride or regret depending on how Sasuke has turned out.
If we consider emotional dominance, Itachi might be more dominant at first as he has always been in control of his emotions and has a lot of secrets that could shock Sasuke. But if future Sasuke has overcome his emotional turmoil and has a clear goal in mind, he could turn the tables. In a physical or power - based sense, it could go either way depending on how the author of the fanfiction has developed their respective powers and skills in the future scenario.
Sasuke might be initially surprised. He is used to the Sakura from his past, so seeing a different, more mature future Sakura could catch him off guard.
In this fanfiction, Sasuke might be shocked to see how much Sakura has changed in the future. Maybe she has become a more powerful ninja, or perhaps she has achieved great things in the medical field, which could make Sasuke view her in a whole new light.
One possible plot could be that future Sakura, with her advanced medical skills and battle experience, goes back in time and meets a younger Sasuke. She might try to prevent some of the tragedies that Sasuke later endures. For example, she could warn him about Orochimaru's true intentions, which would change the course of Sasuke's journey. This would also lead to different interactions between Sakura and Sasuke compared to the original story. Their relationship might develop in a more positive way earlier on, as Sakura from the future has a deeper understanding of Sasuke's pain and the consequences of his actions.
Their relationship would likely become more complex. Since future Sakura has more knowledge about Sasuke, she would approach him differently. She might be more confident and less shy around him compared to her younger self. Sasuke, on the other hand, would be intrigued by this strange girl who seems to know so much about him. He might start to trust her more quickly than he did in the original story, which could lead to a deeper emotional connection between them.
In this kind of fanfiction, Itachi might use his powerful Sharingan abilities. He could perhaps create illusions to mislead Orochimaru and his minions, then quickly snatch Sasuke away. For example, he could make Orochimaru think that Sasuke is in a completely different location while he secretly approaches and rescues him.

In these fanfictions, his love for Sasuke makes him more vulnerable and human. For example, in some stories, he reveals his true motives to Sasuke, which changes their dynamic.
Sasuke and Itachi's story begins with Itachi being an older brother who Sasuke looked up to. But then came the fateful night when Itachi killed the Uchiha clan.
