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.
One idea could be that Jason is jealous of Percy's popularity among the demigods. So, he tries to outdo Percy in various quests, leading to some friendly competition that eventually turns into a real understanding between them. For example, there could be a big quest to retrieve a powerful artifact, and both Jason and Percy are chosen. 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.
One reason could be Percy's popularity. Percy has many friends and is well - liked in the demigod community. Jason might feel overshadowed by Percy's charisma and the attention he gets.
At first, it might show the tension between them due to Jason's jealousy. Jason could be distant or snippy with Percy. But as the story progresses, they might start to communicate. Maybe Percy notices Jason's jealousy and tries to reach out, which begins to thaw the ice between them.
One interesting plot could be that they start off as rivals in a competition but gradually realize their feelings for each other. For example, in a magical quest competition, they initially try to outdo each other. However, as they face various challenges together, they see the good in one another and the romance blossoms.
Another plot could involve a power struggle. Since both Jason and Percy are powerful demigods, there could be a situation where they are competing for a certain power or a leadership role within the demigod community. This competition could escalate into a physical fight.
One plot could be Percy seeing Annabeth spending a lot of time with another demigod on a quest. He gets jealous and starts acting strange around her. This could lead to some misunderstandings between them until they finally talk it out.
In the fanfic, it could be that Percy and Thalia have a certain level of trust and understanding that Jason lacks with either of them. For example, they might communicate in a way that Jason wishes he could with them. Percy's relationship with the gods, especially Poseidon, and Thalia's connection to Zeus might make them a more formidable and enviable pair in Jason's eyes. He may be jealous of the power dynamics and the way they interact within the story.
A plotline could be that Jason is jealous of the easy camaraderie between Percy and Annabeth. Percy and Annabeth have a long history together, and Jason feels left out. So, he tries to insert himself into their conversations and activities. But every time he does, it just backfires. For instance, when they are planning a mission, Jason tries to take over Percy's role in strategizing with Annabeth, but his ideas are not as well - received because he doesn't understand their dynamic as well. This jealousy could also lead to some self - discovery for Jason, where he realizes his own insecurities and works on them.
In fanfiction, it could be related to their popularity among other characters. Percy might be more liked or have more friends, making Jason jealous. It could also be about their achievements. Percy may have accomplished more heroic deeds that overshadow Jason's, leading to his jealousy.
One interesting plot could be Jason and Piper going on a quest together. They might face various monsters and challenges that test their relationship and individual strengths.
