One aspect could be Naruto's emotional state. He would be deeply hurt by the banishment. He might struggle with feelings of anger and sadness. Meanwhile, the village may start to experience internal strife as some shinobi question the decision. Naruto, during his banishment, could train intensively and come back stronger than ever. He might also learn about the history of other villages and find connections to his own past. This could lead to him having a new perspective on the ninja world and his place in it.
In this type of fanfiction, Naruto could be banished to a far - off land. Maybe he discovers a new form of chakra or ninja technique there. He could also form a new community with outcasts like himself. As for the village, Sasuke might feel guilty about Naruto's banishment and try to convince the village elders to reverse their decision. But the political situation in the village could be complex, with some factions seeing Naruto as a threat even after he retrieved Sasuke.
It could be some of the village elders. They were the ones who decided to banish Naruto, so they could continue to oppose him even when he's in exile. They might see his growing power and influence as a threat to their traditional ways of running the village.
Naruto may turn more cautious. The Sasuke retrieval was a dangerous and complex situation. In fanfiction, it could make him think twice before jumping into action. He may analyze situations more carefully to avoid potential disasters. For instance, he won't be as quick to engage in a fight without considering all the possible outcomes. This is a big change from his usually head - first approach. He may also become more protective. Having almost lost Sasuke, he could be overprotective of his friends and the village, constantly on guard to prevent any harm from coming to them.
Well, perhaps in the fanfiction, after bringing Sasuke back, Naruto discovers that there are some secrets that the village has been hiding from him all along. When he tries to expose these secrets, the village sees it as a betrayal and turns against him. He might then be forced to team up with some unexpected allies outside of the village to clear his name and fight for what he believes is right. It could also be that Sasuke's return actually brings some kind of curse or danger with it, and Naruto is wrongly blamed for it.
Another development could be that it causes some conflict within their group of friends. Some might be accepting right away, while others might be skeptical or have concerns about how this will affect their team dynamics. There could be a lot of discussions and arguments about whether Naruto should continue to be part of the group in the same way.
In this fanfiction, Naruto could develop a new set of skills related to childcare. He would learn how to make baby Sasuke happy, feed him, and put him to sleep. Sasuke, on the other hand, could start to see Naruto as a true brother figure from a very young age, which would shape his personality and relationships in the future.
Maybe Naruto gets banished and ends up in a place full of ancient and powerful artifacts. He discovers how to use these artifacts to enhance his own abilities. He also forms alliances with some outcasts in this new place who share their combat skills with him. As a result, he becomes powerful not just in terms of his ninjutsu but also in terms of strategy and teamwork.
The relationship between Naruto and Sasuke is complex. In this retrieval fanfiction, their past memories together could play a big role. Flashbacks of their time at the ninja academy, their first missions, and the bond they formed could be used to heighten the drama of Naruto's quest to bring Sasuke back.
In a non - adult 'Sasuke kidnaps Naruto' fanfiction, a possible plot development could be that Sasuke kidnaps Naruto in order to protect him from a greater threat that he doesn't think Naruto is aware of. Maybe there's a new enemy in the Naruto - verse that Sasuke believes only he can handle, and he thinks Naruto will be safer away from the action at first.
One possible plot development could be that Sasuke is in a life - threatening situation, perhaps against an extremely powerful enemy. Naruto sacrifices himself to give Sasuke a chance to escape or defeat the foe. This would likely lead to Sasuke being filled with guilt and regret, and might change his whole outlook on life.
Naruto, having been banished, may initially lose his sense of purpose. However, with Karin by his side, he could find a new reason to strive. He might develop a more nuanced view of the ninja world and its politics. Karin, on the other hand, could develop a softer side. She has always been in a tough situation, but Naruto's kindness could make her more empathetic. She may also start to trust others more, especially Naruto, which is a big step for her character.
