There could be a school janitor who is actually an old demigod who retired from the hero business. He could give Percy some valuable advice based on his own experiences. And of course, Percy will surely meet Annabeth's classmates, some of whom could be friendly and some not so much, depending on how they react to the new boy in school.
Percy could meet the school bullies. And they might pick on him at first, but then be in for a big surprise when he shows his strength. Also, he might encounter some teachers who suspect there's something different about him. Maybe a science teacher who notices his quick reflexes during an experiment or a history teacher who is amazed by his knowledge of ancient mythology.
He might meet normal high school students. There could be the typical jocks, nerds, and popular kids. Maybe he'd encounter a really smart student who is intrigued by Percy's different way of thinking. Or he could meet some mean students who pick on him at first but then learn to respect him.
One possibility is that Percy clashes with the school's jocks or popular kids. Since he's an outsider, they might pick on him at first. But then Percy shows them what he's made of, not with brute strength necessarily but with his quick thinking and his ability to outwit them. He could also get involved in a school competition, using his unique skills to help his team win.
He might meet his former classmates who have changed a lot since he left. Maybe some new students who are intrigued by his reputation.
Well, she might immediately stand out. She's super smart and used to a different kind of education in Camp Half - Blood. At Percy's school, she could ace all the academic subjects, especially in areas like architecture - related studies since she has a passion for it. Maybe she'd also get into some trouble with the school bullies who don't like smart new kids. And she'd probably befriend Percy's other friends, but also keep a bit of an air of mystery about her demi - god status.
Well, she might cause quite a stir. Maybe she'll outshine everyone in academic competitions, which could make some students jealous. And she could also form a study group with Percy and their friends, sharing her vast knowledge of mythology and ancient civilizations.
He could meet some Aboriginal heroes or spirits. They might have their own powers and knowledge that Percy can learn from.
Maybe Percy would struggle to fit in at first. He's used to a different world, like Camp Half - Blood. But with Annabeth by his side, he could start to adapt. He might make new friends or get into some trouble with the school bullies, only to show off his demigod skills in the end.
They would probably meet their old classmates. People like Grover, who was their friend in high school, would surely be there. Maybe some of their old study group members or teammates from school sports teams.
Well, Percy might face some academic challenges at Annabeth's school. Since he's used to his own demigod training, normal school subjects could be a bit tough for him at first. For example, he could struggle with math or history classes.
