The relationship between Draco and Ron could take a complete turn. Draco's protection of Hermione could shatter Ron's pre - conceived notions about Draco. Ron might have always seen Draco as the typical Slytherin bully, but now he has to face the fact that Draco is protecting Hermione. This could make Ron feel guilty about his own actions towards Hermione or his general attitude towards Slytherins. On the other hand, Draco may start to feel a sense of superiority over Ron for being the one to protect Hermione. But at the same time, he might also feel a bit of envy towards Ron's relationship with Hermione, which could add another layer of complexity to their relationship.
Well, it definitely makes things more complicated. Ron would probably be very confused and angry at first. He might see Draco's actions as a form of interference or even an insult. He may think Draco has some ulterior motives towards Hermione.
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.
One possible reason could be that Draco has had a change of heart. Maybe he realizes that Hermione is a person worthy of protection regardless of her House or her friendship with Ron. He might have seen some injustice about to befall her from Ron and his Gryffindor bravado getting out of hand.
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.
At first, they're likely to be shocked. But then they start to understand each other more. Draco might become more protective of Hermione, and Hermione might see a different side of Draco. They go from being rivals to having a family - like bond.
In some fanfictions, at first, Draco might be intimidated by Ron's bullying. But as the story progresses, he could start to fight back, which then makes Ron realize that his bullying is wrong. This realization can lead to a begrudging respect between them. For example, they might find themselves in a situation where they have to work together against a common enemy, and through that experience, they start to understand each other better.
Over time, if the fanfiction progresses, Hermione could become a sort of bridge between Ron and Draco. She might encourage them to get along, now that Draco has shown that he can be on Hermione's side. Draco might also start to see Ron in a different way, realizing that Ron's jealousy or rudeness towards Hermione was born out of his own insecurities. This could potentially lead to a more complex and interesting dynamic between the three of them.
If Draco steals Hermione from Ron in fanfiction, it might show a different side of Hermione. She might be attracted to Draco's intelligence in a different way than Ron's loyalty. This could lead to new magical adventures where Hermione uses her knowledge in a more Slytherin - like way, influenced by Draco. It could also make for some interesting interactions between the Gryffindors and Slytherins, as now there's a connection between them through Hermione. The story could explore how love can cross house boundaries in a more extreme way than what we see in the original books.
Draco might be motivated by jealousy. He could be jealous of Ron and Hermione's friendship or a possible romantic relationship between them. So he tries to harm Hermione out of spite.
It can make Hermione seem more rebellious. In canon, she's with Ron, so in this fanfiction scenario, her leaving Ron for Draco shows that she's willing to break away from the expected and follow her own heart, even if it means going against her friends' expectations.
In some fanfictions, Ron becomes more open - minded. He starts to look past Draco's Slytherin heritage and snobbish exterior. For Draco, he often becomes less arrogant and more empathetic towards Ron's situation as a not - so - wealthy Gryffindor.
