Charlie might be a character who has known Hermione for a long time, maybe through some other connections in the wizarding world. He sees Hermione as someone in need of protection from Ron, whether Ron is acting out of his own accord or is being influenced by external forces. In relation to Ron, he is the one who stands against Ron's actions towards Hermione.
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, 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.
They would become more protective of each other. Ron would be more vigilant about Hermione's well - being as she is now the mother of their child. And Hermione would be more understanding of Ron's insecurities as a new father.
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.
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.
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.
Yes, there are likely fanfictions with such a plot. Fanfiction writers often explore alternative storylines and relationships within the Harry Potter universe. However, this goes against the canon relationship of Ron and Hermione in the original books.
