Well, in many fanfictions, Percy is often shown as being physically protective. For example, he would jump in front of Annabeth if there was any danger, like facing a monster attack. He might also be verbally protective, not allowing others to say mean things about her.
Percy's protectiveness in fanfiction can manifest in him being over - cautious about Annabeth's participation in dangerous activities. He may try to persuade her not to take on certain risky tasks, even if she's determined. This is because he values her so much and can't bear the thought of losing her. He also shares his powers or resources with her to make sure she's always in a position to protect herself. For example, he might give her some of his underwater breathing ability - related items if they were in a water - related dangerous situation.
In some fanfictions, Percy's protectiveness of Annabeth can be seen in his constant worry about her safety. He would keep an eye on her during quests, even if she was fully capable herself. He might sacrifice his own comfort or convenience to ensure her well - being. For instance, he would give her the last bit of food or water if they were in a scarce situation. He also stands up for her in social situations, like when some demigods might be jealous of her intelligence and try to undermine her, Percy is right there to defend her honor.
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.
In some cases, Percy might be protective in more emotional ways. If someone were to say something mean or critical about Annabeth in the fanfiction, Percy would be quick to defend her. He would stand up for her and not let anyone undermine her confidence or abilities.
One scenario could be when they are in a battle against a powerful enemy. Percy stays close to Annabeth, using his sword skills to fend off any attacks that come near her. He makes sure to cover her back as she uses her strategic mind to plan their moves.
Probably Poseidon, as he is Percy's father and has a vested interest in his son's well - being. Zeus might also be protective in some cases, despite their past differences, as Percy is a hero who often saves the world which benefits Zeus's realm as well.
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.
Maybe in some fanfictions, Annabeth could be written as betraying Percy's trust. For example, she might side with his enemies or reveal his secrets, which would deeply wound Percy emotionally.
Annabeth could also be angry, not at Percy but at the situation or the forces that led to his death. She might vow revenge and start on a journey to find out who or what was responsible for Percy's sacrifice and make them pay. This could lead her into a whole new set of adventures and challenges as she tries to come to terms with her loss.
She'd probably be shocked at first. But then her face would light up with joy. After all, she and Percy have been through so much together.
She might be heartbroken at first. She could try to jog Percy's memory by showing him things that were important to them.
Their relationship in the fanfiction could develop in a more mature way. College is a time of self - discovery, and they would be no exception. Percy might become more confident in his abilities and be more assertive in the relationship. Annabeth could become more empathetic towards Percy's insecurities. They could also start planning for their future together, like thinking about post - college life and how they can continue to fight for the good of the demigod world while also having a normal life. Maybe they even consider starting a demigod training program for future generations on their own.
