She might become more independent. Without the structure of Hogwarts, she'd have to figure things out on her own. For example, she'd have to find her own sources of magical knowledge. This could make her a bit of a maverick in the wizarding world.
Her relationships would be different. Instead of having school friends like Harry and Ron, she might form alliances with other self - taught wizards or those from different magical backgrounds. This could lead to a more diverse and complex social network, which in turn would shape her character in unique ways. For instance, she could become more diplomatic as she deals with different magical cultures outside of the Hogwarts - centric wizarding world.
She could end up in a non - magical educational institution for a while. During this time, she might try to apply her love for learning in a different context, like studying advanced sciences. However, her magical abilities would still be there, and she could end up using them in unique ways, perhaps accidentally, which could draw the attention of the wizarding world and lead to her being brought into the magical community in a very different way than going to Hogwarts.
Her character might develop in a way that she constantly tries to prove herself. Because of her parents' polar - opposite reputations, she would feel the need to show that she is not defined by their actions or reputations. She could excel in both academics and magic - related sports, like Quidditch, to gain respect.
Hermione's character would likely become more laid - back. Growing up in the Weasley household, she'd be exposed to their carefree and fun - loving nature. She might not be as uptight about rules and studies all the time. For example, she could start joining in on the twins' pranks more often.
Hermione's character would likely be more complex. The founders had their own quirks and beliefs. If she was under their influence from a young age, she would inherit some of those traits. For instance, if raised by Salazar Slytherin, she might have a more calculating side, while still maintaining her good nature. This combination would make her a very interesting and different character compared to the Hermione we know in the original books.
If Hermione joins the BAU in fanfiction, her character would develop in many ways. Firstly, her knowledge base would expand as she learns about forensic science and modern - day criminal psychology. Her magical knowledge would start to blend in unique ways with her newfound skills. Emotionally, she'd become more resilient. Dealing with the horrors of some of the cases would toughen her up. Socially, she'd learn to communicate in a more direct and less academic way, which would be a big change for her. She might also start to see the world in a more grey - area way rather than the more black - and - white view she had in the wizarding world.
In a fanfiction where Hermione is adopted by Bellatrix, her character development would be complex. On one hand, she would have to adapt to the dangerous and unpredictable environment of Bellatrix's world. This could make her more resourceful and street - smart. She might also start to show some signs of the ruthlessness that Bellatrix has, but only as a means of self - preservation. However, deep down, she would still hold onto her core values of friendship, loyalty, and the pursuit of good magic. For instance, she might pretend to go along with Bellatrix's plans while secretly working to undermine them and help the side of good. This inner struggle would shape her character in a very different way from the original Hermione in the Harry Potter series.
Hermione's character would become more complex. She might start off being more in tune with the dark side, but her natural goodness could still be there. It would be like a battle within her. She could have a very different style of magic, more in line with Bellatrix's chaotic and powerful style. However, she would also face a lot of internal conflict as she realizes the true nature of the things she's been taught.
Maybe in the fanfiction, Harry has some bad experiences at Hogwarts before. For example, he might have been bullied by some students or had a really tough time with certain teachers. So he doesn't want to go back.
It could be that in this fanfiction, Harry has found a new place outside of Hogwarts that he feels more comfortable in. He might have made new friends or discovered new magic that he can't practice at Hogwarts, so he doesn't want to go there.
