It can create a sense of loss and change the dynamic among the characters. The other characters might have to adjust to Castle's absence, and it could lead to new alliances or rivalries.
The plot could take a darker turn as Castle leaving might be a catalyst for negative events. For example, if Castle was the one who usually solved problems or brought a sense of humor to the story, his departure could lead to a more somber and difficult situation for the remaining characters.
Well, Castle leaving because of Josh could also open up opportunities for new characters to enter the story. Maybe someone comes in to fill the void left by Castle, and this new character could bring their own set of storylines and interactions. It might also force the existing characters to grow and develop in ways they wouldn't have if Castle had stayed. For instance, a character who was previously reliant on Castle might have to become more independent and resourceful.
Perhaps in the fanfiction, Josh has a different set of values or goals that conflict with Castle's. If Josh is pushing for changes or actions that go against what Castle believes in, it might drive Castle away. For instance, if Josh is more focused on power and wealth and is willing to do unethical things to achieve it, and Castle is an ethical person, he would leave to distance himself from such behavior.
The plot could shift focus completely. Maybe the fanfic was about Tim Drake's relationships in Gotham, but once he leaves, it could turn into a story about how Gotham changes without him. It might explore how the villains react to his absence or how the city copes without his vigilante presence.
Well, it can add a lot of drama to the plot. For starters, it could lead to a reconciliation arc between Hinata and Naruto. Their relationship would be in a state of flux, with Naruto perhaps being initially hesitant to forgive or trust her again. This would create tension and anticipation for the readers. Also, Hinata's regret might make her more determined to make amends, which could lead to her taking bold actions to get back into Naruto's good graces and the story's main events.
He might react with jealousy. He could glare at Josh and then give Beckett a hurt look before storming off.
Sakura's regret could lead to her making amends. She might start doing things to show Naruto she's sorry, like helping him in his missions or protecting him. This changes the power dynamics between them and also affects how other characters interact with them, as they all witness this shift in their relationship.
He might be in denial at first. He could keep trying to convince himself that there's no way Beckett would leave him.
Percy's leaving could also have an impact on the family's reputation in some fanfictions. People in the wizarding community might start to gossip, which could put additional pressure on the Weasley family. And some characters outside the family, like Harry, might feel a sense of loss as Percy was also part of his extended circle. He might try to mediate between Percy and the rest of the Weasley family if he gets the chance.
In fanfiction, when Tony leaves NCIS, it often makes the remaining characters feel a sense of loss. For example, Gibbs might become more withdrawn as he has lost a key member of his team. Ziva may struggle with feelings of abandonment since she and Tony had a deep connection. McGee could feel the pressure of having to step up more in Tony's absence. The team dynamics change significantly, and they have to re - evaluate how they work together.
For the other members of the Bat - family, like Dick Grayson or Barbara Gordon, it could create a rift. They might be caught in the middle between Tim and Batman. They may also start to reevaluate their own positions in the Bat - family, wondering if they too should consider leaving or changing their roles.
The plot could take a darker turn. Without Jiraiya's guidance, Naruto might make some wrong decisions. This could lead to him getting involved with the wrong people or getting into dangerous situations that put his life and his goals at risk. On the other hand, it could also lead to Naruto finding his true self more quickly as he has to rely solely on his own instincts.
