One idea could be that Percy's sneeze accidentally triggers some sort of magical reaction. For example, it could cause a mini - tsunami in the middle of Camp Half - Blood because his powers are all jumbled up due to his sickness. Another plot could involve Percy sneezing and accidentally revealing his location to some monsters who are on the hunt for him while he's weakened by the illness. Maybe his friends have to figure out a way to keep him hidden and also cure his sickness at the same time.
His friends would first be really concerned. Annabeth would be in her problem - solving mode. She'd try to analyze the symptoms, not just the sneezing but also any other signs of Percy's sickness like his temperature or any strange marks on his body. Grover would stay by Percy's side, constantly offering moral support. He might also use his empathy link with nature to see if there are any plants that could help. Leo would likely try to invent some sort of device that could either stop the sneezing or figure out what's causing it, while Piper would use her charm - speak to try and soothe Percy when the sneezing fits get really bad.
His sneeze could be related to his demigod abilities in a more defensive way. Suppose an enemy tries to use a spell or attack that targets his water - based powers. His body could automatically react with a sneeze, which releases a small burst of water - like energy that deflects the attack. It's like his body's natural defense mechanism using his demigod powers in an unexpected way.
In this kind of fanfiction, one scenario could be that Will Solace uses his healing powers to try and cure Percy. He might be really worried as Percy is not only his friend but also someone he cares about deeply. Maybe he brings Percy to the infirmary in Camp Half - Blood and stays by his side, constantly checking on his condition and using his medical knowledge and powers to make Percy better.
One common theme is the vulnerability of the characters. Percy, who is usually strong and heroic, becomes weak when sick, showing a different side of him. For example, in many fanfictions, he might struggle to even stand up or use his powers.
One possible scenario could be that in the fanfiction, the sick person is a demigod who has been poisoned during a quest. Percy Jackson and Will Solace team up to find a cure. Percy uses his water - related powers to purify some of the ingredients needed for the antidote, while Will Solace, with his healing skills, tries to keep the sick demigod stable. They face various obstacles along the way, like monsters trying to stop them from reaching the final ingredient. In the end, they manage to save the sick demigod and strengthen their friendship.
Well, maybe Percy could be poisoned by a monster in disguise at school. He starts feeling really sick, like having a high fever and being super weak. His friends, like Annabeth, suspect something is wrong and start investigating. They might find out that there's a new threat in the school that's targeting demigods.
One common theme is the struggle of Percy dealing with his sickness while still having to face the challenges of the demigod world. It could be a physical illness that weakens his powers or a mental affliction that affects his decision - making. Another theme might be his friends rallying around him to help him get better, showing the strong bonds between the characters in the 'Percy Jackson' universe.
Annabeth would probably be very worried and take charge. She'd start researching immediately, looking through books in the camp library to find a cure. Grover would be constantly by Percy's side, using his nature - related powers to try and make Percy more comfortable, like bringing in fresh air and plants to help him feel better.
These fanfics can have a significant impact. They add new dimensions to the characters. For Percy, being sick shows his vulnerability, which is not always explored in the original books. It makes him more relatable to fans who have also experienced illness. Fans can then engage more deeply with the character.
