Perhaps they are forced to work together on a project in Camp Half - Blood or Camp Jupiter. As they spend time together, they discover a deeper connection and end up in a make - out session. Another plot could be that there is some sort of magic or spell that makes them feel an intense attraction towards each other, leading to a romantic encounter.
Finding 'Percy and Jason make out' fanfiction might be a bit of a challenge. First of all, the Percy Jackson fandom has a wide range of stories, and not all of them will feature this particular scenario. Secondly, different authors have different takes on the characters' relationships. Some might see Percy and Jason as more of rivals or just friends. But it's not impossible. You could start by looking for stories tagged with both of their names and then narrow it down to those with a romantic theme.
One common plot is after a tough battle. For example, Percy and Jason have just fought a powerful enemy. They're both exhausted and injured. They find comfort in each other's arms, and that's when the cuddling happens. It's a way to show their bond and how they support each other in difficult times.
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.
A plotline could involve some sort of magical or supernatural influence that makes Percy and Nico's feelings for each other more intense. They might be under a spell that heightens their emotions, and this leads to them making out. Then, they have to figure out if their feelings are real or just a result of the magic while also dealing with the reactions of their friends and the wider demigod community.
Well, a common theme could be the forbidden love aspect if there are elements in the story that suggest their relationship is not fully accepted. This can add a lot of drama and tension. Another theme might be the power of attraction and how it overcomes any initial differences or hesitations they had. It could also be about the connection between them on a deeper level, like a spiritual or emotional bond that is manifested through the physical act of making out.
One consequence could be that it divides the fan community. Fans who like Jason might not appreciate Percy being portrayed as hating him, and vice versa. This could lead to arguments and a split in the fandom.
Jason might hate Percy fanfiction because it often creates scenarios that he finds unrealistic or untrue to the original story. For instance, if the fanfiction pairs Percy with characters in a way that doesn't make sense in the context of the original series, Jason would likely be put off. Another factor could be that the fanfiction might over - sexualize Percy or other characters, which is something Jason would not approve of if he values the integrity of the original characters.
Perhaps they argue over a girl. They are both heroes and might have feelings for the same person. Jealousy and competition could spark an argument between them. Also, their loyalty to different camps, Camp Half - Blood and Camp Jupiter, could be a source of conflict. They might have different ideas on how to handle the relationship between the two camps, which would lead to arguments.
One interesting plot could be a competition between them for a powerful magical artifact. Percy uses his water - based powers, Jason his lightning and flight, and Nico his control over the dead to outwit each other in a race to find it.
