Well, Ron could have developed a more patient side to his personality. He's had experiences that taught him to be more understanding. Hermione may have become more laid - back. Maybe she realized that she was too uptight before. When they reunite, Ron's new - found patience helps him deal with Hermione's still - somewhat - controlling nature. And Hermione's more laid - back attitude allows Ron to feel more at ease around her. It's an interesting dynamic shift that can make for great storytelling in fanfiction.
In many fanfics, their relationship develops through shared hardships during the search for Horcruxes. They rely on each other more and more, which deepens their emotional connection.
Maybe a new dark wizard or witch emerges. This character is extremely powerful and manipulative. They target Ron and Hermione because they are Harry's closest friends. By turning them against Harry, this antagonist hopes to isolate Harry and make him easier to defeat. The new antagonist could have some unique magical abilities that allow them to control the minds of others or create very convincing false scenarios.
In some fanfics, the proposal might happen during a trip they take together. Maybe they're exploring an ancient wizarding library, and Ron discovers a really old and rare book that has a special meaning for them. He decides that this is the perfect moment. He takes Hermione to a quiet corner of the library, and with the magical atmosphere of the old books around them, he proposes. Hermione, of course, is overjoyed and says yes immediately.
Hermione would likely be very angry at first. She is a strong - willed character and being kidnapped would go against all her principles of freedom and rights. She would probably try to reason with Ron immediately, using her logical arguments to make him see how wrong his actions are.
Well, Harry Potter is often included. He's their best friend, so it makes sense that he would be around to help out with the baby. Maybe he becomes the baby's godfather and is always there to offer advice or protection. Another common character could be Ginny Weasley. As Ron's sister, she would likely be very involved in the baby's life, perhaps babysitting or helping Hermione with motherly advice since she has her own children in the original story.
Harry Potter often shows up. Since he's their best friend, he might be caught in the middle of their divorce, trying to mediate or just being there for both of them. His presence can add a lot of emotional depth to the story as he struggles with loyalty to both Hermione and Ron.
Well, in some versions, Ron might use his quick wit and knowledge of Hogwarts' secret passages to outmaneuver Draco. He could lead Hermione to safety through a passage that Draco doesn't know about.
The relationship could take a very different turn. Ron might become extremely jealous, especially if he has feelings for Hermione. This jealousy could lead to him lashing out at Hermione and even trying to drive a wedge between her and Draco. Hermione, in turn, might be frustrated with Ron's immaturity and start to distance herself from him. But if they are able to communicate effectively and Ron realizes his jealousy is unfounded, they could start to rebuild their relationship on a more mature and understanding basis.
In these fanfictions, Ron's jealousy is portrayed in various ways. Sometimes he'll try to interfere with Harry and Hermione's time together. He might create small misunderstandings between them on purpose. Other times, he'll show his jealousy more subtly, like by looking sad or disappointed when they share a private joke or moment. His body language can also give it away, like crossing his arms and frowning when they are being friendly with each other.
