Sometimes, it leads to a reconciliation arc. After leaving, she might realize that she still has a connection to the Order. Through a series of events, she and the Order members could come to understand each other better, and she might eventually rejoin or work together with them in a new way.
The story could also focus on her solo adventures. She might go on a journey to discover more powerful magic or ancient knowledge that could help in the fight against the Dark forces in a way that the Order didn't consider. This could lead to her becoming a more powerful and self - reliant character.
There could be a new character introduced who helps Harry get over Ginny. This new character could be a friend or a potential love interest. Meanwhile, Ginny might face her own challenges in her new life, like dealing with the guilt of leaving Harry or facing some new enemies. As the story progresses, there could be a possibility of them reconciling or moving on completely from each other, depending on the direction the fanfiction author wants to take.
The story may take a turn where Harry becomes a sort of mediator between the houses. Since he has left Gryffindor, he has a different view and can help bridge the gaps between the different groups in Hogwarts. He might also embark on a personal journey of self - discovery outside the framework of Gryffindor values, which could lead to new magical abilities or insights.
The story could also develop in a way where both Percy and Annabeth grow separately. Percy might discover new powers or aspects of his personality while he's away. Annabeth, on the other hand, could focus more on her own goals and become even more independent. Eventually, they might meet again and have a new understanding of each other.
Another way the story can develop is that the remaining Avengers try to win Tony back. They realize their mistakes and make efforts to reconcile with him. This could involve a lot of emotional scenes and character growth for both Tony and the other Avengers.
After leaving Gryffindor, Harry may embark on a journey of self - discovery. He could travel to different places, learn new magic, and meet new characters outside of the Gryffindor - centric environment. This new path could lead him to discover a new purpose or a new way to fight against the forces of evil that doesn't rely on the Gryffindor identity.
Often, his friends will try to find him. Misty and Brock, or his newer friends like Serena, might set out on a journey to track him down. Their search could lead them to new places and new Pokémon they wouldn't have otherwise encountered.
The story may split into different plotlines. Harry's journey on his own could lead him to new allies and enemies. He might face challenges that change his character in ways different from when he was with the Golden Trio. Meanwhile, Hermione and Ron could be dealing with threats in Hogwarts or the wizarding world that they have to handle without Harry. As the story progresses, there could be a build - up to a reunion, which is often a very emotional and significant moment in the fanfiction.
In some cases, the story might focus on Hermione's journey after leaving. She could end up in a new and strange part of the wizarding world, meet different characters, and learn new magic. Meanwhile, Harry might be on a quest to find her and in the process, uncover secrets about the wizarding world that they never knew before. This can lead to a reunion later on, but with both of them changed by their experiences.
Often, Harry and Hermione have to fend for themselves without Ron at first. They might feel betrayed and angry, but they also realize they need to be stronger. Then, they start to uncover the real reasons behind Ron's betrayal. Maybe they find out that Ron was being controlled or manipulated, and they try to save him from the dark side he has fallen into.
Often, there's a period of sadness and confusion for both of them. Hermione might try to figure out what she did wrong and reach out to Harry. Meanwhile, Harry might start to realize that he misses her friendship. Then, there could be a reconciliation scene where they finally talk things out and their friendship is restored, stronger than before.
