It would likely be strained. Ron has a strong dislike for the Malfoys, so if Hermione was suddenly part of that family, he'd be conflicted. Harry might also be suspicious as Lucius has been an enemy. Hermione would be caught in the middle, trying to balance her old friendships with her new family ties.
Hermione's relationship with Ron and Harry would face significant challenges. Ron's family has a history of being against the Malfoys. So Ron would find it hard to accept Hermione as part of that family. Harry, who has fought against Lucius, would also be wary. Hermione would have to work hard to keep her friendships intact, perhaps having to hide her new family situation from them at first.
For Hermione, her relationships with Ron and Harry would become extremely complex. Ron, with his in - built prejudice against the Malfoys, would initially be hostile towards Hermione's new family connection. Harry, too, would be on guard as he knows Lucius's true nature. Hermione would be in a difficult position, having to prove that she is still the same person. She might try to keep her two worlds separate, but that would be hard as Ron and Harry are such important parts of her life.
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.
It might make Ron a bit jealous at first. He could see it as Hermione choosing Harry over him in a way. But then he realizes it's just a friendly gesture and starts to be more supportive of their friendship.
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.
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.
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.
Well, they might become closer to Neville. Since they lost Harry, Neville could step in as a more reliable friend. He has always been there and now with Harry out of the picture, they could rely on each other more. Also, they might have a different relationship with the teachers. Without Harry's influence, the teachers might view them in a new light, either more positively or more negatively depending on the situation. For example, Snape might still be mean to them, but McGonagall might be more sympathetic as she sees them dealing with the loss of a friend.
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.
Draco's relationship with Hermione could change drastically. He might start to feel sympathy for her, which could turn into a reluctant friendship. Lucius, however, would be more resistant to any positive change. But as Hermione shows her strength even while injured, he might develop a begrudging respect. Overall, Draco could become more of an ally to Hermione, while Lucius would be in a more complex situation of having to re - evaluate his views due to Draco's new attitude.
It makes them more self - reliant as a duo. Without Ron, they can't fall back on his more laid - back approach sometimes. So they have to be more decisive together.
