One possible plot could be that in the fanfic, Jason is jealous of Percy's natural leadership skills. Percy always seems to know what to do in a crisis, and the other demigods look up to him. Jason, on the other hand, feels like he has to constantly prove himself. So, he starts trying to outdo Percy in every mission, which leads to some tense and exciting situations. For example, they might both be trying to solve a mystery at Camp Half - Blood, and Jason's jealousy causes him to take unnecessary risks just to show he's better than Percy.

Jason, being jealous, initially tries to take the lead all the time but realizes that Percy's skills are also valuable and they end up working together successfully.

He might be more careful not to show off his skills too much around Jason, which shows his maturity.
In many fanfictions, Percy's jealousy of Jason can be due to multiple factors. Jason may have a more seamless integration into the Roman camp's hierarchy.
