Well, first of all, it can make Percy's journey more difficult. He has to deal with Luke's possessive actions on top of whatever challenges he already has. This possessiveness can also lead to character development for both of them. Percy may become more determined and independent, while Luke may become more desperate or evil - depending on how the fanfiction is written. It can also introduce themes of control and freedom, adding depth to the overall plot.
Luke's possessiveness can change the alliances in the fanfiction. Other characters might side with Percy against Luke, or some might be influenced by Luke's possessive behavior and turn against Percy. This reshapes the power dynamics in the story.
Hestia's possessiveness can shape the plot in many ways. It might lead to Percy being isolated from other characters who could be important to his development. This in turn can create a series of events where Percy has to either break free or come to terms with Hestia's possessive nature. Also, it could attract the attention of other powerful beings who either oppose or support Hestia's possessiveness, adding more twists to the plot.
Luke's jealousy can drive him to take actions that create conflict. He might try to undermine Percy's achievements or come between Percabeth. For instance, he could spread false rumors about Percy to turn others against him.
It can create conflict. For example, if other characters don't like Jason's possessiveness, it can lead to arguments or even fights.
Well, it could affect the plot in various ways. The gods' possessiveness might mean that Percy has limited freedom. He may constantly be under the watchful eyes of the gods, which restricts his actions. Also, it could lead to power struggles among the gods themselves, with Percy caught in the middle. Maybe one god tries to protect Percy from the others' possessive actions, adding more twists to the story.
The jealousy might cause Percy to view Luke's actions more critically. Even if Luke has good intentions, Percy's jealousy could make him suspect Luke of ulterior motives. This could gradually erode any positive feelings Percy had for Luke before. On the other hand, Luke might start to feel the coldness from Percy and become confused or even resentful. Their relationship could devolve into a cycle of suspicion and animosity, with the jealousy acting as a catalyst for all these negative emotions and behaviors.
It can create a lot of tension. For example, if Harry has other friends or potential love interests, Fleur's possessiveness might lead to jealousy and arguments. This can drive a wedge between Harry and his friends or make the relationship with the other love interest more complicated.
Percy may become more reserved. With Artemis being possessive, he might start to hold back his normal, outgoing nature. For example, he may not be as quick to jump into new adventures or make new friends.
In the fanfiction, Percy's possessiveness might also be demonstrated by his need to be included in all of Annabeth's plans. He may feel left out or threatened if she starts making plans with other people without him. He wants to be a part of everything she does, almost like he owns a part of her time and attention.
It can cause friction. Peter may feel smothered by Tony's possessiveness, leading to arguments as he tries to break free and be his own hero. For example, Peter might want to take on a mission alone, but Tony refuses to let him.
It could also drive Reyna to focus more on her own development. Maybe she decides to prove herself even more without Percy's affection. This can lead to her taking on new challenges and growing as a character in the fanfiction. She might become more independent and self - reliant.
