A possible plotline is that Teddy has a hard time fitting in with his peers because of his unique family situation (being Lupin's son and an orphan). Hermione steps in and arranges for him to join a special study group with some very diverse students. This helps Teddy not only make friends but also learn about different cultures within the wizarding world. There could also be a plotline where Hermione and Teddy discover a hidden library in Hogwarts that contains forbidden books, and they have to keep it a secret while exploring the knowledge within.
One interesting plotline might be that Teddy shows an early aptitude for a type of magic that is considered dangerous or misunderstood. Hermione, as his godmother, has to defend Teddy against those in the wizarding community who are afraid of his powers. She might have to take Teddy on a journey to find an expert in that type of magic to train him properly and prove that his powers can be used for good. This would involve facing many challenges and meeting various strange and interesting characters along the way.
One plotline could be Teddy getting into trouble at school and Hermione using her connections and wits to get him out of it. Maybe he accidentally turned a teacher into a toad during a Transfiguration experiment gone wrong. Hermione would then have to figure out how to reverse the spell without getting Teddy in too much trouble. Another could be Hermione teaching Teddy some ancient spells that are not taught in regular Hogwarts curriculum, which leads to an adventure when they discover an old magic artifact related to those spells.
Hermione as Teddy's godmother would likely be very involved in his upbringing. She might use her intelligence and resourcefulness to help Teddy in difficult situations. For instance, if Teddy faced any problems at Hogwarts, Hermione could quickly come up with solutions. Her influence could also extend to his social life. She could encourage Teddy to befriend those with similar interests in learning and magic, shaping his social circle in a positive way.
In some fanfictions, there might be a plot where Teddy gets into trouble at Hogwarts. Harry, as a sort of mentor figure, steps in to help him out. This could lead to a strengthening of their bond as Harry defends Teddy and teaches him the right way to handle the situation. Maybe Teddy was wrongly accused of using dark magic, and Harry uses his experience to prove Teddy's innocence.
One possible plotline could be how Harry and Hermione adjust to their new roles as parents. They might face challenges like Teddy having magical outbursts due to his young and powerful magic. For example, Teddy could accidentally transform objects in the house when he gets excited or scared. Another aspect could be Teddy's education. Harry and Hermione would surely want to give him the best magical education, so they might start teaching him basic spells at a very young age. They could also introduce him to the wizarding world's history and culture, taking him to places like the Ministry of Magic to show him how things work.
Well, in some fanfictions, Teddy might find a way to time - travel and actually meet his parents in person. This would create a very emotional and exciting story. He could interact with them, get to know them as real people, not just the stories he's heard. And through this experience, he might change the course of some small events in the past, but without majorly disrupting the wizarding world's history.
One interesting plotline could be Hermione discovering a long - lost family inheritance that gives her new magical abilities. For example, she might find out she has the power to control time in a unique way, which she then uses to solve a major mystery at Hogwarts.
Some fanfictions explore a different relationship dynamic between them. Maybe Harry has a problem that only Hermione can understand and help him with, and this brings them closer in a way that's different from their normal friendship. It could be something related to his connection with Voldemort or his family history.
One interesting plotline could be Hermione's journey of self - discovery within the pack. Maybe she discovers new magical abilities or a deeper understanding of her own strength as she interacts with the pack members.
One interesting plotline could be Hermione's struggle to hide her maledictus condition from her friends at Hogwarts. She might constantly worry about turning into the beast associated with the curse and how it could endanger those around her.
One possible plotline could be Hermione trying to find a way to break the curse on her own. She might use her vast knowledge of magic from the library. Another could be her friends, like Harry and Ron, going on a dangerous quest to find the antidote for the curse. And perhaps there's a plotline where the curse has some unforeseen side effects that change her relationships with other characters.
A common plotline is an alternate universe where Snape is not as bitter and Hermione befriends him more easily. They could be involved in a battle against a new dark force, and their combined intelligence and magic powers are crucial for victory. Also, there could be a plot where Hermione accidentally enters Snape's mind through some experimental magic and discovers his deepest secrets, which then changes their relationship.
