You could start by looking on fanfiction platforms like Archive of Our Own (AO3). Just use the search bar and type in 'Jason getting wound treated'. There might also be some on Wattpad, but AO3 generally has a wider range of fanfictions.
In some fanfictions, the wound treatment could be a part of Jason's journey of self - discovery. He might be injured while on a personal quest, and as he heals, he gains new insights about himself. The treatment process could also involve some sort of magic or special technology depending on the setting of the story. For instance, if it's a science - fiction setting, he could be treated with some advanced alien medical device, and this could introduce new elements to the story, like the origin of the device or how it affects Jason in unexpected ways.
Jason could get hurt by a curse. His physical pain is accompanied by mental and emotional turmoil as the curse tries to corrupt his mind. His friends must find a way to break the curse, which might involve going on a quest to find an ancient artifact or a powerful magician. Along the way, they learn more about Jason's past and the origin of the curse.
One great Jason Grace fanfiction is 'Jason's New Quest'. It takes Jason on an adventure that's not in the original books, with new characters and challenges. It really delves into his character and shows his growth in different situations.
In Percy Jackson and Jason Grace fanfictions, Percy is often seen as more of a maverick. He has a very strong connection to the sea and his own unique sense of humor. Jason, on the other hand, is more of a traditional hero type in fanfictions. He's more rule - bound and has that Roman discipline. Their characterizations can be really different in fanfictions depending on the writer's take.
One could be 'Jason's Painful Ordeal' where he gets seriously injured in a battle against a powerful new foe. His friends are left to deal with the aftermath, and it shows their grief and determination to save him.
In some fanfictions, Percy Jackson and Jason Grace can be depicted as brothers. Fanfic writers often like to create new relationships and backstories for existing characters, and this is one such example. It allows for new and interesting plotlines to develop.
One common theme is the exploration of his physical and mental limits. When Jason is hurt, it allows the author to show how far he can be pushed before breaking. For example, in some stories, his physical injuries lead to mental breakdowns as he struggles to cope.
It's inappropriate. These characters are from a world that is meant to inspire adventure, friendship, and heroism. Sexual fanfiction not only misrepresents the essence of the story but also can be a source of discomfort for many fans, especially those who are young and look up to these characters.
Love and romance can also be a theme. Some fanfictions explore a romantic relationship between Jason and the OC. This could involve the OC being a new arrival at Camp Half - Blood and catching Jason's eye, or they might have a pre - existing connection that develops into love over time. However, these stories also often balance the romance with the action and adventure elements typical of the Percy Jackson universe.
