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.
In some fanfictions, Harry and Hermione form new alliances with other characters. They could team up with Neville or Luna, for instance. Meanwhile, Ron might be working with the bad guys, but he gradually starts to have doubts about his actions as he sees the true nature of those he has joined. Eventually, there could be a big confrontation where Ron has to choose between his new 'allies' and his old friends.
Often, it ends with Hermione realizing her mistake. She might fight to make amends and try to save Harry from whatever danger she has put him in. For example, if she had handed him over to the bad guys, she could then turn against them and help Harry escape.
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.
In fanfiction, their friendship often develops through shared challenges. For example, when they face a new dark magic threat in the wizarding world, they rely on each other more. Harry's leadership, Ron's humor in tough situations, and Hermione's knowledge combine to make them closer. They also develop their friendship by having deep conversations about their fears and hopes for the future. Maybe Harry shares his concerns about being the Chosen One, and Ron and Hermione support him wholeheartedly.
In the world of fanfiction, this could be a very dark and interesting plot. It might be that Ron is influenced by some dark magic or some external force that makes him turn against his best friends. Maybe he's jealous of Harry's fame or feels overshadowed by Hermione's intelligence, leading to his betrayal.
After the kiss, their relationship might become more openly affectionate. They could start holding hands more often, stealing glances at each other, and being more protective of one another.
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.
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.
Some fanfictions develop their relationship through shared adventures outside of Hogwarts. They go on secret quests together, relying on each other's skills. Harry's courage and Hermione's intelligence complement each other during these adventures. As they face challenges and overcome them, their relationship blossoms into a romantic one while they keep it hidden from their friends.
Their relationship might become stronger as they face the challenges of post - war life together. They have already been through so much during the war, and this shared experience could deepen their bond.
Often, the story will focus on Hermione's struggle to come to terms with her new identity. She may try to find a cure at first. For instance, she might search through ancient magic texts in the library at Hogwarts.
