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 the gods would be completely different. The Olympians would likely be very wary of Percy now. They might see him as a potential threat since Erebus is an ancient and powerful entity. However, some of the minor gods might see Percy as an opportunity to gain more power or status. They could try to ally with him, which would further complicate Percy's relationships with the different factions in the Greek mythological world.
His relationship with Annabeth would become more complicated. She might be initially suspicious of Percy's new connection to Hades, but then come to accept it as part of who he is. Percy would also have a new dynamic with the other demigods. Some might fear him because of his link to the underworld, while others might be curious and want to learn more about his powers.

Grover might be a bit in awe of Percy's new magical side. Percy would also have to form new relationships with the followers of Hecate, who might be very different from the demigods he's used to.
When it comes to his relationship with Hera herself, it would be complex. At first, Percy might be resentful or confused about being adopted by her. But as time goes on, he might start to understand her in a way no one else does. Hera could start to see Percy as a true son, and this could lead to a deep, if somewhat unusual, bond between them. Percy would have to balance this new relationship with his existing ones, and it could lead to some really interesting character development and story arcs.

However, some might be more understanding, especially those who have faced their own identity crises. His relationship with the gods would also change.

Percy's relationship with the other campers at Camp Half - Blood would be a rollercoaster. The children of Poseidon might feel a bit betrayed or confused, as they thought Percy was one of their own.

For example, he could work with the children of Aphrodite to improve relationships in the camp, since Hera has some connection to love and relationships in a different way than Aphrodite. With the gods, his relationship with Zeus would be extremely strained, given Zeus's past issues with Hera. But he might find new allies among the gods who are friendly with Hera, like Hephaestus. Overall, Percy's relationships would be a mix of challenges and new opportunities.
