A possible plotline is that Ron is under a spell that makes him act against his will. He doesn't realize he's betraying Hermione until it's too late. Or perhaps Ron has a secret family obligation that he thinks can only be fulfilled by turning against Hermione. Maybe his family has some old debt or pact with a dark force, and he's forced to choose between his family and Hermione.
One plotline could be that Ron is lured by the promise of power. He betrays Hermione to join a dark wizard or group that offers him something he desires, like more status in the wizarding world. Another could be a love triangle gone wrong. If there's a new character who Ron fancies and this person convinces him that Hermione is standing in the way of their relationship, he might betray her.
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.
One common plotline is exploring their relationship in more depth during their Hogwarts years. For example, a fanfic might focus on how they dealt with jealousy issues when Hermione was spending time with Viktor Krum. Another plotline could be set after the war, where they face new challenges as a couple, like dealing with the post - war trauma together. Some fanfics also like to imagine what would have happened if they got together earlier in the series.
Perhaps in the fanfiction, Ron's jealousy gets the better of him. He might be jealous of Hermione's success or her friendships with other characters like Harry or some of her academic peers. His jealousy could manifest in ways that make Hermione feel suffocated or unappreciated, causing her to end the relationship. Also, Ron may have some habits that Hermione can't tolerate anymore. For example, his slacking off on certain responsibilities or not taking things as seriously as she does.
It could be that Ron is having a bad day or going through some personal issues. And instead of dealing with them in a healthy way, he takes it out on Hermione. For example, if he's feeling insecure about his place in the group, he might lash out at her.
One possible plotline could be a situation where Hermione loses her bra during an adventure with Ron and there's some comical or awkward moments as they try to deal with it without others noticing. Another could be that Ron accidentally sees Hermione's bra and it causes some blushing and confusion between them as they realize their growing feelings for each other in a new light.
One interesting plotline could be that their soul bond allows them to share magical abilities. So, Hermione can access some of Ron's natural charm magic, and Ron can get a boost in his intellectual capabilities like Hermione's. This creates a unique dynamic where they become an even more powerful duo in the wizarding world.
One possible reason could be that in the fanfiction, Bill might be depicted as more mature and worldly compared to Ron. Hermione may be attracted to his experience and the different perspective he can offer.
Perhaps Hermione confronts Ron about his lack of commitment to their friendship or to their studies. In the fanfiction, she might be tired of always having to push him to do better and finally snaps at him. For example, she could bring up all the times he's slacked off during group projects or when they were preparing for exams.
Well, one plotline could be that Hermione is heartbroken by Ron's cheating. Draco, who has secretly admired her from afar, steps in to comfort her. This leads to them exploring a relationship that was previously unthinkable due to their houses' rivalry.
In Ron Weasley and Hermione fanfiction, a common characteristic is the re - imagining of key moments in their relationship. For instance, how they might have first kissed or confessed their feelings differently. There's also a strong sense of loyalty in these stories. Ron and Hermione are shown to be loyal to each other through thick and thin. And the fanfictions often play with the idea of their future. Whether it's their careers, having a family, or their place in the wizarding community, these aspects are explored in different and creative ways.
