In the past, they might have to pretend to be something they're not. This could affect their relationship. If they have to hide their true identities, it could create a sense of mistrust between them at first. But as they get more used to the situation, they could start to understand each other better. They might also meet versions of their parents or other relatives that could influence how they view each other and their family connection.
Their relationship might become more complex. Since they'd be in a different time, they might rely on each other more. In their own time, they had different paths, but going back in time could force them to be closer. They might start to see each other in a new light, like Luke seeing Leia as more of a partner in adventure rather than just a sister.
In time travel situations, they may have to rely on each other in ways they haven't before. For example, if they travel to a time when the Force is not well - understood, Luke may have to depend on Han's non - Force - related skills more. Leia might find herself in situations where she has to mediate between Han and Luke more often, strengthening their bond as a trio. Their relationships would grow deeper as they face new challenges together.
If they time travel, their relationships might become more complex. For example, if they go back in time to before they met, they might initially not trust each other as they do in their own time. Han might be more distrustful of Luke's Jedi abilities, and Leia might not see Han as the hero she knows him to be. But as they face challenges together in the past, they could form deeper bonds in different ways than they did originally.
The relationship would likely be more sibling - like from the start. In the original story, they didn't know they were siblings for a long time. But in this fanfiction, they'd grow up with that knowledge. So, they'd be more protective of each other right away and have a deeper understanding of each other's quirks and abilities.
Their relationship could become stronger. Facing the challenges of the past together, they'd rely on each other more. For example, if they end up in a dangerous situation in the past, they'd have to trust each other completely to get out of it.
In a time - travel scenario, Anakin and Luke's relationship could be transformed. Luke could finally understand his father's struggles more intimately by being present in the past. Padme and Leia might form a stronger bond as well, with Padme being able to mentor Leia in ways she couldn't before. Their relationships would be shaped by the new shared experiences in different time periods and the knowledge they gain from those travels.
In the past, their relationship could be more complex. Kakashi might be suspicious of Naruto's sudden appearance and his knowledge from the future. Naruto would have to prove himself to Kakashi. However, as they work towards a common goal, like saving Konoha from a threat in the past, they would gradually build trust. Their relationship could also change in terms of how they interact with others in the past. For example, they would need to pretend to be normal villagers or ninjas from that time, and this new situation would impact how they relate to each other.
Their relationship might become stronger. In the past, Naruto could show Kurama that he is more than just a host, and Kurama could see Naruto's potential to change things even at an earlier stage.
Their relationship would likely become more complex. At first, they might be more united because they have a common goal of changing the past. However, as they face different situations in the past, their differences could start to surface again. For example, Sasuke might be more focused on revenge - related issues from the past, while Naruto would be more interested in saving lives. This could lead to some arguments between them.
It might become stronger. They'd have to rely on each other more in the past, facing all the unknowns together.
At first, it might be awkward. After all, they've never met their parents before. But as they start talking, they could quickly form a strong bond. Their parents might be proud of the heroes they've become.
