Their relationship with Ron would definitely be different. Harry and Hermione being twins means they would have a lot of inside jokes and shared memories that Ron doesn't have. Ron might get jealous initially because they seem to be excluding him. However, as time goes on, Ron would realize that their bond as twins doesn't mean he is less important to them. He could then start to bond with them in new ways, like helping them with their twin - related magic or investigations.
Ron and Hermione's relationship would change in many ways. For starters, they would be sharing a new level of responsibility. Ron, who was once a bit more laid - back, would have to step up and be more involved in the day - to - day tasks. Hermione, on the other hand, might become more emotional and Ron would need to be there to comfort her. They would also be making decisions together for the future of their family, which could lead to some arguments as they both have strong opinions, but in the end, it would strengthen their bond.
Well, at first, it could be a bit of a shock for both of them and they might have some arguments about how it happened and what to do next. But as time goes on, they'd start to really bond over the idea of becoming parents. Ron would probably step up and be more responsible, and Hermione would see a new side of him. They'd have to support each other through the physical and emotional changes of pregnancy. And their relationship would no longer just be about their romantic feelings for each other, but also about building a family together. This would bring a whole new dimension to their relationship, with more love, but also more responsibilities and things to worry about.
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.
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.
It would likely make their relationship more complex. Harry might feel a bit jealous at first because he had such a strong connection with Sirius. Ron, on the other hand, might be a bit confused. But overall, they would still be her friends. They might be more protective of her, especially if there are threats related to Sirius's past enemies. And Hermione would have to balance her new identity as Sirius's daughter with her long - standing friendships.
If Hermione was Harry's sister, the relationship between her and Harry would be more family - oriented. Ron might initially be a bit jealous as he has to share his two best friends in a different way. But overall, they could form a really strong trio with a new family - like bond.
Well, it really depends on how the fanfiction is written. Some might show Ron being completely outraged and cutting off his friendship with them. But in other versions, Ron could be more understanding. He might see that Hermione and Harry have a special connection that he wasn't fully aware of. He could initially be confused and a bit resentful, but as he witnesses their love growing, he might start to support them, seeing that their relationship doesn't mean he loses his place in their lives.
It could become closer. Without Ron as a third party, Harry and Hermione might rely more on each other. They would have more one - on - one study sessions and adventures, which could strengthen their bond.
If Hermione were a Parselmouth, Harry might initially be a bit wary because of his own connection to Voldemort as a Parselmouth. But eventually, he would come to trust her fully. Ron, on the other hand, would probably be more openly shocked and it might take him longer to adjust. He might be a bit scared at first, but over time, their friendship would remain strong as Hermione uses her ability for good.
If Hermione were Harry's sister, Ron might be a bit more intimidated at first. He has always had a crush on Hermione, and this new connection could make him feel like he has to be on his best behavior. However, as time goes on, he would probably get used to it and their relationship could become even stronger, as Ron would see Hermione as an even more important part of his life through her connection to Harry.
