Hermione's character could develop in terms of her relationships. Through saving Fred, she might form a stronger bond with the Weasley family. She may also become more empathetic as she experiences the fear of losing someone dear. She realizes that there are things more important than just academic knowledge. So, she starts to balance her intellectual side with her emotional side more effectively.
Hermione may develop her leadership skills. When saving Fred, she might have to take charge of a difficult situation, directing others to help her. This could be a new experience for her as she's usually more of a behind - the - scenes planner. Also, she might learn to trust her instincts more. Instead of always second - guessing herself, she becomes more decisive in her actions to ensure Fred's safety.
She likely becomes more confident in her abilities outside of just academic knowledge. Saving Fred would require her to take risks and trust her instincts, which could make her more self - assured. For example, if she has to perform a spell she's not entirely sure about, but does it anyway to save Fred, it shows her growth in believing in herself.
Hermione might become more distrustful of Ron. After being saved by Lucius from Ron, she could start to see Ron in a different light, perhaps as someone with a darker side she hadn't fully recognized before. This could make her more cautious in her interactions with him.
Hermione's character could develop in terms of her understanding of the grey areas between good and evil. Saving Fenrir goes against the common perception of him as a monster. This could make her more open - minded and less judgmental. She might start to see that even the most feared creatures can have a chance at redemption.
Hermione could develop a more complex understanding of magic. Since saving Harry's parents would likely involve delving into some very rare and powerful magic, she would expand her knowledge greatly. This new knowledge could make her more respected among the wizarding community, and she might use her new status to advocate for better magical education and research, all while her character grows in wisdom and leadership.
Well, in some versions, Fred might use his quick-witted magic skills. He could cast a distraction spell to draw Bellatrix's attention away from Hermione. Maybe a spell that creates multiple illusions of himself, confusing Bellatrix long enough for him to grab Hermione and disapparate them to safety.
His courage becomes more evident. By saving Hermione, he shows that he is willing to face great danger for his friend. This act of heroism can make him more confident in his abilities as a wizard.
Hermione, on the other hand, could become more daring. She is already brave, but this situation could push her to take risks she normally wouldn't. She might be the one to suggest trying untested spells or taking paths that are less known in order to escape. As they run, she could learn to trust her instincts more and not just rely on book knowledge.
Hermione's character could develop by becoming more confident in her own instincts. Following Dumbledore, she may start to trust her own judgment more as she observes his actions. For instance, if she disagrees with one of his decisions, she might be more assertive in voicing her opinion, which is a growth from her more deferential nature in the original books.
Hermione's character could become more complex and conflicted. She would constantly be worried about getting caught in her lie, which might make her more cautious. This could also lead to her becoming more secretive, which is a big change from her usually open - book self. At the same time, she might develop a stronger sense of justice as she tries to use her false blood status to fight against the unfairness in the wizarding world.
Often, Hermione's character develops a sense of belonging in adopted fanfics. Since she was an outsider in some ways in the original series, being adopted gives her a new home. This makes her more empathetic towards others who might be in similar situations. And she uses her new - found stability to be more assertive in the wizarding world, standing up for what she believes in even more than before.
