At first, it could be a bit rocky. Percy might think Annabeth is too uptight, and Annabeth might think Percy is too carefree. But as they spend more time together in the high school environment, perhaps during lunch breaks or in after - school clubs, they start to see the good in each other. For example, Percy might notice how Annabeth always stands up for what's right in class debates, and Annabeth might see Percy's loyalty to his friends.
It could develop quickly. They might immediately start planning their next adventure together.
They could start off on the wrong foot. Maybe Percy accidentally spills something on Annabeth's books. But then, they are paired for a debate in class. They realize that they both have really strong opinions and are quite intelligent. This mutual respect starts the development of their relationship.
It could develop into a deeper friendship at first. They might study together and support each other in their college pursuits.
It could be that they face some challenges in their relationship upon meeting again. Maybe there are misunderstandings or new characters that cause some jealousy or friction. However, through communication and their shared experiences, they would work through these issues and come out with an even deeper bond.
It could develop slowly. At first, they might just be acquaintances who exchange polite greetings in the hallways. Then, they could be grouped together for a school project. Through working on it, they'd start to see each other's strengths and weaknesses, and a friendship would begin to form.
It could become more complex. As adults, they have different responsibilities and experiences. Their relationship might start off a bit strained as they try to fit into each other's new lives. But eventually, they could find a new level of understanding and respect for each other.
Sally would likely become a mother figure to Annabeth. She would offer her advice and support, just as she does for Percy. Percy and Annabeth's relationship would become more domestic. They'd have more time to just be together, sharing small moments like having breakfast together in the morning. Their bond would strengthen as they face the normal day - to - day challenges of living together, along with Sally.
It could develop quickly. They might share a glance across the cafeteria and feel an instant connection, and from there start hanging out right away.
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.
It can develop through this moment of closeness. Just the act of her sleeping on him can show a level of trust, which Percy might recognize and it deepens their bond.
