Sure. Itachi's saving of Sasuke was a crucial moment in the manga. It was tied to his hidden motives and sacrifices for the greater good of the ninja world and Sasuke's future.
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.
Maybe it's about protecting Sakura. Itachi might think that Sasuke isn't the right person for Sakura and wants to protect her from Sasuke's darker side. And Sasuke, on the other hand, believes he can protect Sakura better than Itachi and that Itachi has no right to interfere.
One reason could be Naruto's power. In the Naruto universe, Naruto has great power, and both Itachi and Sasuke might see Naruto as a key to achieving certain goals. Itachi might want to protect Naruto because he sees Naruto as a force for good in the future of the ninja world. Sasuke, on the other hand, may view Naruto as a rival in terms of power and influence, and in fanfiction, this could lead to a fight between them over Naruto.
Sasuke might develop more patience. Since Itachi is younger in this fanfiction, Sasuke has to be more understanding. He can't be as impulsive as he usually is. For example, he might have to learn to soothe Itachi when he's scared or upset, which helps Sasuke grow into a more empathetic person.
Sasuke could also be confused. He has always had a mix of emotions towards Itachi, including love, hate, and envy. Being kidnapped by him would add another layer of confusion. He might wonder if Itachi has some new plan or if he's finally going to reveal some long - hidden truth. So, he might hold back on his full - fledged resistance and wait to see what Itachi has to say.
In many fanfictions, Sakura might choose Sasuke. They have a long - established relationship, with Sasuke being someone she has loved since childhood. Her feelings for him are deep - rooted and often in fan - created stories, she remains loyal to those initial feelings.
Itachi. He was a highly skilled and intelligent shinobi. His Sharingan abilities were extremely powerful, and he had a lot of combat experience. He also had a strategic mind, which would give him an edge in a fight over Naruto.
In many fanfictions, Sasuke starts as a character full of anger and a thirst for revenge. But in the context of a relationship with Itachi, he begins to soften. He starts to see Itachi in a different light, beyond just the person who killed their clan. Itachi, on the other hand, is often portrayed as a complex figure with many secrets. 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's character could develop in terms of his loyalty. By saving Sakura from Itachi, he shows his loyalty to his friends and comrades. He is no longer just the revenge - driven Sasuke. He has grown to care about others' safety.
