In fanfiction where Percy and Thalia fall in love, how would their relationship affect their relationships with other characters?

If Percy and Thalia were twins, their relationship with Luke would change significantly. Luke might see them as a bigger threat to his plans. He might try to drive a wedge between them, knowing how strong they could be together. Their relationship with Chiron would also be different. Chiron would have to train them in a way that takes advantage of their twin connection, perhaps teaching them special combat moves that only work when they work in tandem. The gods would also treat them differently. They might be more watchful of the twins, fearing their combined power could disrupt the balance among the demigods.

Some characters might see it as an opportunity. For the Aphrodite cabin, they would be delighted as it would bring them closer to Percy, who is a powerful and respected demigod. However, characters from other cabins, especially those who have rivalries with the Aphrodite cabin, would be suspicious and might try to break up the relationship. They could think that Aphrodite is using Percy to gain an advantage in the power dynamics among the demigods.

For Hinata, she might be disappointed as she had feelings for Naruto. But she would also be kind and respectful of Naruto's choice. Kiba could be teasing Naruto about his relationship with Ino, while also being a bit protective of Ino as a friend. Choji would be happy for Ino, but might also be worried that Naruto's dangerous ninja life could put Ino in harm's way. And the village elders might view this relationship as a potential political alliance, depending on Ino's family status.

If Percy looks at Medusa in a fanfiction, it could strain his relationship with Annabeth. She might be worried that Percy has been turned to stone or that he's been affected in some other negative way. She could become overprotective or even a bit angry at him for getting into such a dangerous situation.

Their relationships could develop in many ways. At first, Percy and Thalia might have some friendly bickering as they used to, but with Nico there, they start to form a more united front. Nico, being a bit more withdrawn, might gradually open up to them more as they face challenges together. Percy could use his natural leadership skills to bring them together, and Thalia's fierce loyalty would make her a great ally for both of them. As they rely on each other more in the chaotic situations, their bonds would strengthen into deep friendships.

It could make their relationships with Annabeth really tense. Since Percy is close to Annabeth, and if he's fighting with Jason over Nico, Annabeth might be caught in the middle. She could try to mediate but also be frustrated with Percy for getting into the fight.

The demigods would be in shock. Percy was a leader among them. His death at the hands of Artemis would make them question the motives and stability of the gods. Annabeth, in particular, would be devastated. She would likely be consumed by grief and then anger, and might even set out on a quest for revenge against Artemis.

Percy and Nico might grow closer as they face new challenges together in Hogwarts. Thalia could initially be a bit of an outsider to their relationship but then gradually become more involved. Percy could act as a mediator between Nico and Thalia at times.

In highschool fanfiction, their relationships could develop in many ways. Percy and Nico could bond over their shared experiences of being different. Percy might help Nico come out of his shell and make more friends. Thalia would be like an older sister figure to both of them. She would protect them from any mean - spirited students. As time passes, they would have sleepovers at each other's houses (or cabins in Percy's case), and during these times, they would share stories and secrets, strengthening their relationships.

It might make some characters jealous. For instance, if the Sacred Gear gives Percy an edge in combat, some of his fellow demigods who are used to being on equal footing with him could start to feel envious.
