In fanfiction, it could be that Charlie has a more mature understanding of Hermione's intellectual pursuits. Ron sometimes struggles to keep up with Hermione's thirst for knowledge. Charlie, with his own expertise in his field, might be able to engage Hermione in more in - depth conversations, leading her to consider a relationship with him instead of Ron.
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.
In this fanfiction, it could be that Ron is under the control of a powerful wizard who wants to get to Hermione for some reason. Charlie discovers this plot and decides to protect Hermione. He sets up various traps and wards around the place where Hermione is staying. When Ron, being controlled, tries to attack Hermione, Charlie is there to intercept him, engaging in a magical duel if necessary to save Hermione.
If Ron and Hermione leave Harry in the fanfiction, it would change the entire fabric of the story. Harry would have to reevaluate his relationships with other characters. For example, he might turn to Neville for support more often. Also, the power dynamic within the wizarding world could shift. Since Ron and Hermione were important figures in the fight against Voldemort, their absence could give the Death Eaters an advantage, or it could inspire others to step up in unexpected ways. Harry would be forced to grow in ways he hadn't before, and it would be a journey full of self - discovery and new challenges.
One possible reason could be a misunderstanding. Maybe they misinterpreted something Hermione said or did, and in a fit of anger or confusion, they decided to leave. For example, if Hermione was working on a project alone without consulting them, they might have felt left out and left in a huff.
Well, this concept might seem a bit out of the blue for some fans. But in fanfiction, anything can happen. Hermione leaving Ron for Charlie could be due to a growing admiration for Charlie's work with magical creatures. She might feel a deeper connection with Charlie's more solitary and dedicated nature compared to Ron's sometimes goofy and laid - back attitude.
Well, it could be for love. In many fanfics, their relationship has been through a lot, and leaving together is a way to start anew, away from the prying eyes and pressures of Hogwarts and the wizarding community.
One possible reason could be that Ron has deep - seated feelings for Hermione that he's not fully aware of yet. In the story, he might be subconsciously drawn to her and thus won't leave her alone.
Perhaps she tries to find them right away. Using her intelligence and resourcefulness, she starts to search for any clues as to where they might have gone. She could ask other friends, like Neville or Luna, if they have seen Harry and Ron. And she might be determined to bring them back, not willing to give up on their friendship easily.
There's often the sacrifice plotline. They might sacrifice their relationship with Hermione to save a large number of people. For instance, they learn that a dark wizard will spare many lives if they abandon Hermione. Also, the jealousy plotline can exist. If a new character becomes closer to Hermione and they feel left out, they might leave out of jealousy and a sense of not belonging in Hermione's new social circle.
In these fanfictions, a common theme is change. Hermione's life changes drastically when she leaves Ron for Charlie. There may be a theme of new beginnings, as she embarks on a relationship with someone very different. The idea of finding a better fit is also there. Maybe she realizes that Charlie understands her more or can offer her more support in certain areas. Additionally, themes related to family and acceptance can come up, especially if the story delves into how the Weasley family reacts to Hermione's choice and how Charlie's side of the family accepts her.
