Some might be excited. They've probably heard a lot about Percy from Annabeth, so they are eager to meet him in person.
There could be a few who are a bit intimidated. Percy has that demigod aura about him. They might feel a bit out of their depth around him, especially if they sense his power. For instance, if Percy gets a bit angry and his eyes flash, they might be scared. But then as they get to know him better, they start to relax.
A couple of them could be jealous. If they like Annabeth in a more than just a friend way, seeing her with Percy might make them envious. They might try to find faults in Percy at first, but as time goes on and they see how much he cares about Annabeth and how brave he is, they might change their minds and become friends with him.
His friends could also be divided. There might be those who immediately embrace Annabeth because they see her as an asset. For instance, if there are any students interested in architecture or strategy (which Annabeth is good at), they'd be thrilled. However, there could be some who are more territorial and feel like she's invading their space, which would create some interesting relationship dynamics in the fanfiction.
Well, he might get into some funny situations. Maybe he shows off his demigod skills accidentally and the friends are all shocked. For example, he could make a fountain shoot water really high just by looking at it in a certain way.
They might be shocked. Percy is not an ordinary guy, and his abilities would be quite a surprise to them.
Some of Annabeth's friends could react with laughter and jokes, while others might be a bit flustered and not know how to act. It really depends on the personalities of the friends in the fanfiction.
Grover would probably be really excited. He might bring all kinds of nature - related gifts for the baby, like a special plant that has protective powers. He would also be very protective of the baby, using his nature senses to detect any danger.
Grover would be super excited. He'd probably start bleating happily and immediately start thinking about all the great food he could eat at the wedding. Jason would be very supportive and offer his help in any way he could, like with security for the big day. Piper would be thrilled and would probably start planning Annabeth's bachelorette party right away. Leo might crack some jokes about Percy finally tying the knot but deep down he'd be really happy for them.
Percy could stand up to Annabeth. He's a strong character. He might confront her directly about her bullying behavior and tell her it's not okay. This could lead to a turning point in their relationship, where Annabeth realizes she's been wrong.
They might be a bit in awe at first. She has a certain presence about her that comes from her being a demigod. Maybe they're curious about her and ask Percy a lot of questions about her later.
The students would probably be very excited. Percy has a lot of charisma and his tales of adventure would be really interesting. Some students might be a bit intimidated at first, but once they see his friendly side, they'd warm up to him quickly.
Well, in the fanfiction, Percy might initially seem a bit out of place among Annabeth's mortal friends. He could accidentally do something that reveals his demigod nature, like reacting too quickly to a threat that normal people wouldn't notice. Maybe he'll be super strong when helping them move furniture or something.
