One possibility is that the Greek class is a place for Percy and Annabeth to show their relationship development. They could be paired up for a project on a particular Greek hero. While working together, they start to understand each other better. Annabeth might be really into the research part, while Percy brings in his practical understanding of how the hero's traits could be applied in a real - life - or rather, demigod - life - situation. And through this, their bond deepens as they both contribute their unique perspectives.
Perhaps Percy would use his knowledge of Greek gods and goddesses to impress the teacher. He could share some unique insights about a particular deity that are not commonly known. This could lead to him getting special privileges in the class, like being excused from a difficult assignment or getting extra credit.
It could be Chiron in disguise. Since he has a vast knowledge of Greek mythology, he would be a great teacher. He could also use his centaur form in some secret or magical way during the class to teach important lessons that only Percy and Annabeth would notice.
One possibility is that it could lead to Percy's downfall. If Annabeth, who has been his close ally and friend, betrays him, it might shatter his trust not only in her but also in others. He could become more isolated and vulnerable, making it easier for his enemies to target him.
Well, it could be that Annabeth and Percy meet in a different setting than in the original stories. For example, they could meet in a modern city but still have to deal with their demigod issues. They might discover new powers or abilities within themselves as they interact. And there could be some romantic moments as their relationship often has that element in fanfictions.

Well, perhaps in the fanfiction, they initially feel a bit awkward sharing the bed. But as the night progresses, they find comfort in each other's presence.

They could end up falling asleep while holding hands, symbolizing their strong bond.
Well, perhaps Percy plans this elaborate scheme to ask Annabeth out. He might enlist the help of their friends, like Grover. Grover could set up a picnic in a beautiful meadow. Percy then shows up with a bouquet of Annabeth's favorite flowers and asks her out. She would be touched by the effort he put in and say yes. Then they start planning all the things they want to do together on their first official date.
Maybe in 'Annabeth meets famous Percy fanfiction', the famous Percy fan could be from another dimension or time. Annabeth would be really confused at first.

They could end up teaming up to face some new threat in the world of fanfiction that is related to Percy's story, like a new monster that is attracted to the idea of Percy's fame within this fan - created world.
In some fanfictions, Annabeth and Percy might struggle with PTSD. They could have nightmares about their time in Tartarus. Percy might be overly protective of Annabeth, and they may need time to heal their emotional wounds together.
