A third plot could be a magical accident. There could be a powerful spell gone wrong in the library at Hogwarts. Tom and Hermione are both researching different things when the spell backfires and binds their magic together in an unexpected way. This causes a strange attraction between them which leads to a relationship and Hermione getting pregnant. The story could then be about how they figure out how to deal with this magical bond and the new life they are about to bring into the world.
One plot idea could be that it's a time - travel based fanfic. Hermione somehow gets sent back in time and meets Tom Riddle before he fully turns into Voldemort. Their relationship starts out as a strange sort of intellectual connection. Maybe she tries to prevent him from going down the dark path and in the process, they develop feelings for each other which leads to her getting pregnant. This could then create a whole new timeline where the wizarding world is different due to Tom's change of heart.
Well, perhaps in the fanfiction, Hermione as a Veela has the ability to enter Tom Riddle's dreams. In his dreams, she shows him the consequences of his future actions as Voldemort. This makes Tom start to have doubts about his planned path of evil, and he has an internal struggle between his dark desires and the newfound influence of Hermione's Veela presence.
One plot idea could be that Hermione travels back in time and tries to prevent Tom Riddle Jr from becoming Voldemort. She might use her knowledge and magic skills to change his path. Another could be a scenario where they meet in an alternate universe where the rules of good and evil are more blurred, and they form an unlikely alliance to face a greater threat. Maybe Hermione gets trapped in a magically created world by Tom Riddle Jr, and she has to outwit him to escape and in the process, she discovers some hidden secrets about his past that could have changed his future.
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.
Well, perhaps in the fanfiction, Hermione time - travels to Tom Riddle's era and she attempts to understand his early life better. She could try to find the root of his evil and change it. For example, she might discover that a particular event in his childhood was the turning point. As for Tom Riddle traveling to Hermione's time, he could be fascinated by the advanced magic and the different social structure in the wizarding world, which might make him question his own beliefs.
One common plot twist is that the pregnancy might be part of a dark plan by Tom Riddle. Maybe he intended it to gain some sort of power or to manipulate Hermione in a more complex way. Another could be that Hermione discovers something unusual about the baby that links it to a greater mystery in the wizarding world.
Maybe in a fanfiction, there is a prophecy that foretells of a child born from Hermione and Tom that will bring great change to the wizarding world. This prophecy forces them to be together, and they have to deal with the prejudices of others. Hermione uses her knowledge to try and understand Tom's dark past better, and Tom, in turn, learns from Hermione's kindness. The pregnancy then becomes a central part of the story as they wait for the birth of this prophesied child.
Yes, it can be quite a popular theme in some corners of the fanfiction community. Some fans are intrigued by the idea of pairing such contrasting characters as Hermione and Tom Riddle and exploring the 'what - if' scenario of a pregnancy. It adds an element of drama and a new dimension to the relationship between these two characters from different Hogwarts eras.
One plot idea could be that Fem Harry, with her unique perspective as a female in a male - dominated wizarding world, catches Tom Riddle's attention in Hogwarts. He's intrigued by her different way of approaching magic. Maybe she's more empathetic and uses magic in a way that he's never seen before, leading to a complex relationship where he both admires and is jealous of her power.
One idea could be a time - travel fanfic where Harry goes back in time and tries to prevent Tom Riddle from becoming Voldemort. He could try to befriend the young Tom and show him a different path. Another could be a fanfic where Harry and Tom are somehow trapped in an alternate dimension together and have to work together to escape, all while Harry tries to understand what made Tom turn so evil. A third idea is a fanfic where Tom Riddle actually has a change of heart early on due to some magical accident that makes him experience a different kind of love and kindness, and Harry has to deal with this new Tom in Hogwarts.
One great fanfiction could be where Hermione travels back in time and tries to prevent Tom Riddle from turning into Voldemort. She uses her vast knowledge of magic to try and sway him towards the good side. This could lead to some really interesting interactions as Hermione's modern - day magic knowledge clashes with the magic of Riddle's time.
