His relationships would be turned upside down. His friends would be heartbroken and might have to re - introduce themselves to him. Some might become overprotective, while others could be distant, not knowing how to handle this new Percy.
With his family, it could be really tough. His parents would struggle to connect with him again. His mother might be constantly trying to jog his memory with stories from his childhood. And his father, Poseidon, might be conflicted between using his divine powers to help and respecting the natural process of Percy regaining his memory.
With his friends like Grover, Percy would seem like a completely different person. Grover is used to Percy's emotions guiding his actions. Now, Percy would be cold and calculating. His friends would have to constantly remind themselves that this is still Percy, but it would be hard for them to connect on the same level. They might start to doubt if they can still trust him, as his lack of emotions could make his decisions seem unpredictable.
His relationships would shift in many ways. With his family, if he has one by that point, they would be deeply concerned and try to help him adjust. His comrades in the Hidden Leaf Village would be more watchful over him. Enemies would likely underestimate him at first, which could be both a danger and an opportunity for Naruto. His relationship with the tailed beasts might also change, as they might be sympathetic towards his new disability and offer different kinds of support or advice.
Percy's relationship with his father, Poseidon, could be a bit strained. Poseidon might not understand this strange 'Jedi' thing that his son is so into. He could see it as a distraction from Percy's duties as a demigod. However, Percy could try to convince his father that there are similarities between the power of the sea and the Force. With his friends from Camp Half - Blood, those who are more open - minded would be excited to learn about the Jedi ways from Percy. They would engage in discussions about how Jedi ethics can be applied in their demigod lives. But the more conservative demigods might see Percy as a threat to their traditional values and try to isolate him.
His relationship with Annabeth would be different. She'd have to get used to this new side of Percy. There might be some initial tension as she tries to understand his ice powers and how they fit into their relationship. His friends at Camp Half - Blood would also be in awe and a bit cautious. They'd respect his new power but might not know how to act around him at first. Some might even be jealous.
His relationships with his old friends would be strained. They might be wary of him at first. For example, Annabeth might be very cautious around him as she's not sure if he can be trusted. But over time, if Percy proves himself, they could slowly rebuild their friendship.
His relationship with Annabeth might change. She could be both impressed and a bit jealous of his new skills related to Hephaestus. Percy would now have an area of expertise that she doesn't fully understand. With the Hephaestus kids, he might start as an outsider but gradually earn their respect as he proves himself in tasks related to their father's domain.
The relationship with Poseidon would be extremely complicated. Poseidon would be torn between his love for Percy and his fear of what Percy could become as Kronos' twin. He might try to distance himself from Percy at first, which would deeply hurt Percy. On the other hand, Percy's relationship with some of the minor gods might improve. Since they are often overlooked by the major gods, they might see Percy as a potential ally in changing the status quo. Percy's relationship with Luke, if he were still alive in this fanfiction, would also be interesting. Luke might try to use Percy's connection to Kronos to his advantage, but Percy would have to be careful not to be manipulated by Luke.
His relationship with Annabeth would definitely be affected. She might be a bit wary at first, since Nyx is such an unknown and powerful entity. But she would also be there to support Percy as he figures things out.
Among the demigods at Camp Half - Blood, some of the more romantic - minded ones might flock to Percy, thinking he can give them advice on love since he's related to Aphrodite. But Percy would be really out of his element here. And his relationship with the more 'tough' or battle - focused demigods might be strained, as they might see his Aphrodite connection as a sign of weakness or something that doesn't fit with their warrior - like image of him.
Well, it could really damage his friendships. His friends might be shocked or scared by his outburst and start to distance themselves from him. They may not understand why he lost his temper and think he's become a different person. For example, if he yells at them during his fit of anger, they could take it personally and feel hurt.
