Well, he might be really flustered. Percy is often portrayed as a bit of a goof in some fanfictions. He could stutter and turn red, not really knowing how to handle the situation.
Percy could also respond in a more confident way in certain fanfictions. Maybe he has grown more self - assured in the high school setting. He might flirt back a little, using his charm and sense of humor. For example, he could crack a joke about the situation or give a clever comeback that shows he's not intimidated by the flirting.
He might be initially in shock. Percy has been through a lot with Annabeth, so being dumped would come as a huge blow. He could be speechless for a while, unable to process what has just happened.
Well, it depends on who is flirting with her in the fanfiction. If it's someone she doesn't like, she'll probably be dismissive and give cold responses. However, if it's someone she has a bit of an interest in, she could be coy and a bit shy while still maintaining her confident facade.
Percy could also be very sad. He has so many memories and relationships at the camp. He might go into a state of depression for a while, not knowing where to go or what to do next. But then, he would probably start to think about how to get back in or how to make things right. He might start looking for evidence to clear his name if he was wrongly accused. He could also look for new allies outside of the camp who could help him in his situation.
Well, initially Percy would be confused. He would try to understand why someone he trusted would turn on him. Depending on the severity of the betrayal, he might isolate himself for a while, thinking that he can't trust anyone. But as he is Percy, he would also start to look for a way to clear his name and prove his innocence. He would use his wits and his skills to figure out what really happened and expose the truth. He may also have some internal struggle about whether to forgive the betrayer if the situation allows for it.
His friends would be very worried. Annabeth would immediately start looking for solutions. She'd be using her strategic mind to figure out what kind of poison it is and how to get an antidote. Grover would be freaking out a bit but still try to be useful, like using his sense of smell to detect any strange scents around Percy that could give a clue about the poison.
He might be angry at first. After all, he may feel that the school doesn't understand him or his situation. He could be thinking that his actions were justified in some way.
He might be shocked at first. Naruto is used to seeing Kurenai as an ally, so being hurt by her would be unexpected. He could immediately ask her why she did it. If it was a serious injury, he might struggle to stay conscious while trying to understand the situation.
Well, Sirius could get really flustered. It could lead to some comical or tense moments depending on the context of the fanfiction. The howler might reveal something he doesn't want others to know.
Annabeth's reaction could vary. If she's been missing Percy a great deal, she'll be overjoyed. She might show him around the school, proud to introduce him to her friends or teachers (if possible in the context of the fanfiction). However, if she's in the middle of something important like a test or a big project, she could be a bit annoyed at first but still be happy to see him deep down.
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.
