Their college life would likely be a blend of normal and extraordinary. Since they are demigods, they might have to secretly keep an eye out for any monsters that could disrupt their studies. In terms of their relationship, they would support each other in every way. Percy would cheer Annabeth on during her late - night study sessions for big architecture projects, and Annabeth would be at every swim meet, shouting for Percy. They'd also find time to explore the campus and find hidden, magical spots that only they could sense.
They might face new challenges like dealing with difficult professors. In college, the academic pressure could be a big deal for them. Percy might struggle with some theoretical subjects, while Annabeth could thrive. And they could also encounter new mythological creatures that are lurking around the college campus.
They'd probably divide their time carefully. Percy might use his powers in the pool to his advantage in swim meets, which also helps him keep in shape for any potential demigod battles. Annabeth would use her knowledge from college architecture classes to better understand ancient structures related to their demigod world. They'd communicate well and support each other, so if a demigod emergency arises, they'd figure out how to handle it without sacrificing too much of their college work.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
Percy might be a bit flustered and embarrassed. He's protective of his relationship with Annabeth, so having Magnus walk in might make him feel like their privacy has been invaded. He could quickly try to shield Annabeth or just look really shocked.
Their shared experiences play a big role. They've been through so much together, like countless battles and adventures. Percy has seen Annabeth in tough situations and he knows how strong she is, but also how vulnerable. So he feels the need to protect her. For instance, they might have had a close call in a previous adventure where Annabeth was nearly killed, and that memory makes Percy extra vigilant.
Their relationship is likely to be complex. They are friends and comrades who have fought side by side many times. So, there's a strong bond of loyalty between them.
Well, one possible reason could be that Percy made a really stupid decision without consulting Annabeth first. Like, if he went off on a dangerous mission on his own when they were supposed to be a team. Annabeth is a very strategic person and she might feel betrayed or extremely frustrated by such actions.
