Hermione might find Tom to be a very intelligent yet troubled boy at the orphanage. She could use her own intelligence and magical skills to gain his trust. For instance, she could perform some simple but impressive magic tricks for him. This would make Tom interested in her and open up the possibility of a deeper connection between them in the fanfiction.
Well, in the fanfiction, Hermione's presence at the orphanage with Tom could be part of a time - travel experiment gone wrong. She has to adapt quickly and deal with Tom. Maybe she tries to give him books on positive magic and stories of great wizards who used their power for good. But Tom, being Tom, is a bit of a challenge. He's both intrigued and a bit resistant to her ideas. As time passes, their relationship becomes a complex dance of Hermione trying to change his future and Tom trying to figure out her true intentions.
In this fanfiction, Hermione could be on a mission to retrieve a powerful magical artifact that has somehow ended up at Tom's orphanage. When she meets Tom, she initially sees him as just a child in need. But as she spends more time there, she realizes that he has a great potential for both good and evil. Their relationship could develop as she tries to influence him towards the good while also achieving her mission.
One possible scenario in this fanfiction could be Hermione traveling back in time and ending up at Tom Riddle's orphanage. She might try to prevent him from turning into Voldemort. For example, she could use her knowledge of magic to show him a different path, perhaps by introducing him to the concept of love and friendship in a more positive way than he ever experienced in his original life.
Another possibility is a scenario where Hermione is on a mission to study the early life of Voldemort for some academic or magical research. While at the orphanage, she discovers some hidden secrets about Tom Riddle's family that were previously unknown. This could lead to a series of events where she has to protect this knowledge from falling into the wrong hands, all while interacting with a young and curious Tom Riddle.
Tom could manipulate Hermione. He is a very intelligent and cunning boy. He might see Hermione as a means to an end. Maybe he could use her knowledge of magic to further his own studies in the dark arts. He could pretend to befriend her while secretly plotting to use her magic for his own evil purposes. However, Hermione is also smart and would likely catch on eventually.
One idea could be that in the orphanage, Tom discovers a hidden magical ability within Hermione that she was unaware of. Maybe they team up to face a mysterious threat that is targeting the orphans. This could lead to them exploring the secrets of the orphanage together.
Their relationship could start off as a mutual curiosity. Tom might be intrigued by Hermione's intelligence and Hermione by Tom's mysterious aura. As they spend more time together in the orphanage, they gradually become friends and rely on each other for support, sharing their hopes and fears.
You could also create a fanfiction where a new character, an orphan just like Tom, arrives at the orphanage. This new character could either be a positive influence on Tom, trying to show him kindness and friendship, or they could be in competition with him for the limited resources or attention in the orphanage. This would add a new dynamic to the story of Tom Riddle in the orphanage.
Hermione would likely approach Tom's dark past with a great deal of research. She'd probably dig into the history of Voldemort's early years to understand what led him down that path in the first place. By knowing the root causes, she could try to prevent the same things from happening to Tom. For example, if she found out that loneliness and a sense of being an outcast were factors, she'd make sure Tom had a strong support system at Hogwarts.
In some fanfictions, Snape might be affected by the Daydream Charm in Hermione's presence. Maybe he starts daydreaming about a world where Hermione is his protege instead of Harry. This could lead to a whole new set of interactions between them, with Snape being more open and Hermione being more receptive to his teaching methods.
It could be that Dog Lemon is a lost dog that Hermione finds on her way to Hogwarts. She takes it with her and hides it in her dormitory. The other students soon find out, and they all work together to keep Dog Lemon a secret from the teachers. Meanwhile, Dog Lemon starts to show some unexpected magical talents that help the students in various ways.
One common theme is redemption. Often, the orphans in these stories have had difficult pasts, and through the love and care of Harry and Hermione at the orphanage, they find a new path in life.
