Percy's relationships with his fellow demigods would be full of suspicion. They would be constantly watching him to see if he shows signs of following Chronos' evil intentions. However, Percy could also use this new position to bring together characters who were previously at odds. For instance, he could broker a truce between two warring groups in the demigod world by showing them the greater threat of Chronos.
His relationship with Annabeth could become more complex. Since Percy has this new role as the Champion of Aether, Annabeth might feel a bit left out or worried that he's getting too powerful. His friendships with other demigods at Camp Half - Blood could also shift. Some might look up to him more, while others might be envious. And his relationship with the gods could change too. The gods might see him as a more important figure and try to use him for their own purposes.

His relationship with the gods would be complex. The gods who are friends with Ares might be more favorable towards Percy. However, the ones who dislike Ares, like Poseidon in some ways, might be disappointed in Percy. Poseidon might worry that Percy is being led astray by Ares and could try to persuade him to give up this new role.
Percy's relationship with his mortal family would also be affected. Since Hestia is all about home and family, Percy could be more involved in protecting his mortal family. He might use his new powers and influence to ensure their safety and well - being. This could bring him closer to his mother, and he could also start to learn more about his family's history and heritage through Hestia's connection.

With the other demigods, Percy could become an outcast at first. They might see his adoption by Erebus as something unnatural or dangerous.

For example, he could use his shadow - related abilities to help in battles or rescue missions, showing that he's still on their side.
His relationship with Annabeth would be severely strained. Annabeth, who has always known Percy as Poseidon's son, would be confused and a bit distrustful.

However, some might be more understanding, especially those who have faced their own identity crises. His relationship with the gods would also change. The gods who were once somewhat friendly or at least neutral towards him might now see him as a threat. Zeus, for example, would be extremely wary of Percy's Tartarus - related abilities.
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.
