A possible plot could be a spell that makes Hermione fall in love with the wrong person. This would create a lot of drama as she struggles with her new - found feelings while her real friends try to show her the truth and break the spell. It could also explore themes of manipulation and the power of true friendship.
Well, in some fanfictions, Hermione raised at Hogwarts might face a plot where she has to deal with time - travel anomalies. Since Hogwarts is filled with magic, there could be some time - related magic gone wrong. She could end up traveling back in time and meeting the founders of Hogwarts. This would be really interesting as she could learn from them directly and bring back that knowledge to the present time at Hogwarts. Also, a plot could involve Hermione being raised by a different set of professors, not the ones we know from the original books. This would give her a different perspective on magic and she might develop her own unique style of spellcasting based on their teachings.
Well, there could be a plot where Hermione, through a spell gone wrong, enters a dimension where Tom Riddle won the wizarding war and rules with an iron fist. She has to pretend to be on his side to survive and in the process, she discovers some redeeming qualities in him that she didn't expect. Another idea is that Hermione is researching a new form of magic that was only experimented with by Tom Riddle. As she tries to replicate his experiments, she accidentally summons a part of his spirit and they engage in a battle of wits and magic. And yet another plot could be that Hermione is sent on a mission to stop a new dark wizard who is using Tom Riddle's old methods, and in order to understand the enemy better, she uses a time - turner to go back and study Tom Riddle directly, which leads to unexpected interactions and consequences.
One plot could be Hermione using the Time - Turner to go back and change Snape's perception of her. Maybe she tries to show him that Gryffindors can be worthy allies. Another could be that Snape discovers Hermione's use of the Time - Turner in a way that wasn't in the original books and they end up working together secretly to stop a new dark threat.
One possible plot could be Hermione using her knowledge to help the Marauders in some way. For example, she might assist them in dealing with a difficult spell or situation that they were struggling with in their original time. Another plot could be her trying to change certain events that she knows will have negative consequences in the future, but then facing the moral dilemma of interfering with time.
One possible plot could be how Hermione and Remus initially react to the marriage law. Maybe Hermione is initially resistant as she has her own academic and career goals. But as she gets to know Remus better, she starts to see the potential in their relationship. For example, they could bond over their love for knowledge, with Remus sharing his experiences at Hogwarts from an older perspective and Hermione impressing him with her new - age magical theories.
One possible plot could be Hermione using her modern knowledge and magic skills to raise Tom in a more positive environment. Maybe she teaches him about equality and kindness from a young age, which changes his view of the wizarding world and prevents him from turning into the dark lord. For example, she could introduce him to muggle culture and values, making him more accepting of different kinds of people.
Another interesting plot is a time - travel one. Hermione goes back in time and has to interact with a younger Lucius and Snape. It's fascinating to see how her knowledge of the future affects her interactions with them and how they react to her. For example, she might try to prevent certain events that Lucius or Snape were involved in, which could change the course of the wizarding world.
One interesting plot could be a case of false accusation. Maybe someone framed Hermione for a serious dark magic crime she didn't commit. The story could then focus on her trying to prove her innocence from within Azkaban, perhaps with the help of some unexpected allies like house - elves who she had previously befriended. Another plot might involve a time - travel twist. Hermione is sent to Azkaban in the present, but through some magical accident, she travels back in time while in prison and has to find a way to change the events that led to her imprisonment. A third possibility is a political conspiracy within the wizarding world. High - ranking officials send Hermione to Azkaban to silence her because she was about to expose some dark secrets about the Ministry of Magic.
In certain fanfictions, Hermione could be sent back in time to improve relations between wizards and other magical creatures. She might start by helping Hagrid in his early days at Hogwarts, teaching him more about how to properly care for and protect the creatures. This could lead to a more harmonious co - existence between all magical beings in the wizarding world. By doing this, she could also change the way wizards view and interact with these creatures in the future.
One possible plot could be the exploration of how Hermione's strong will and intelligence clash with Tom Riddle's dark and manipulative nature within the context of a forced marriage law. Maybe she tries to reform him in some ways.
