She becomes more confident in her decision - making. Following Dumbledore's orders, she often has to make quick and important choices. This forces her to trust her instincts more, which in turn makes her more self - assured. For instance, when she has to decide whether to enter a dangerous area to retrieve an important item for Dumbledore, she learns to weigh the risks and benefits on her own and act accordingly.
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.
She might be involved in tasks like researching ancient magic. Dumbledore, being very knowledgeable, could send Hermione to dig into old books and scrolls in the library to find information about a particular dark magic threat or a powerful spell that could be used for good. For example, if there's a new dark wizard on the rise, he might ask Hermione to look for any historical records of how similar threats were dealt with in the past.
One possible plot twist could be that Hermione discovers a hidden side of Dumbledore. Maybe she finds out about a secret mission he was on long ago that has consequences in the present. For example, she could stumble upon a hidden prophecy related to Dumbledore that changes the way she views him and the entire wizarding world's future.
Hermione's character often becomes more confident. Since she has knowledge of the future, she can take more risks and be bolder in her actions. For example, she might be more assertive in her interactions with teachers or other powerful wizards.
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'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.
Hermione's character would likely experience a great deal of internal conflict. On one hand, she has her Gryffindor values and her loyalty to her friends like Harry and Ron. But on the other hand, she now has this new family connection to the Malfoys. She might become more empathetic towards Draco and start to understand the pressures he has faced as a Malfoy. Her confidence might be shaken a bit as she has to re - evaluate who she is in the context of this new family. She may also become more secretive as she tries to figure out how to handle this new situation without losing her old friends.
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.
In these fanfictions, Hermione often becomes more confident. For example, in some, her demigod powers give her a new sense of self - assurance. She may start off being a bit hesitant about her new identity but as she learns to control her powers, she grows into a more assertive character.
