A big theme is the exploration of Hermione's character growth. With Sirius as her guardian, she might be exposed to different aspects of magic and life that she wouldn't have otherwise. For example, she could learn more about the darker side of magic and how to combat it. Also, the theme of loyalty often comes up, as Sirius is loyal to Hermione and she to him in return.
The theme of legacy also plays a part. Sirius represents the Marauder's legacy, and by raising Hermione, he passes on that legacy in some way. She might inherit their sense of adventure, their love for knowledge (which she already has but it could be enhanced), and their willingness to stand up against injustice. In these fanfictions, this transfer of legacy is often a central part of the story.
Another theme is family. These fanfictions often explore what it means to form a non - traditional family. Remus, Sirius, and Draco create a new family unit that defies the norms of the wizarding world. It shows that family doesn't have to be blood - related. There are also themes of acceptance. The wizarding world has to accept this new family structure, and Draco has to accept his new life and values.
In these fanfictions, a recurring theme is the change in their relationship. The pregnancy can bring them closer together or create new tensions. Also, the theme of protecting the unborn child from potential threats in the wizarding world, whether it's dark wizards or the prejudiced views of others, is quite common. Additionally, there may be exploration of how Hermione's academic life is affected and how Sirius adapts to the idea of becoming a father, which are all interesting aspects that authors like to explore.
Protection is also a big theme. Given Sirius' nature, he feels a sense of responsibility to keep Hermione safe. This could be from dark wizards or from the general dangers that lurk in the wizarding world. Sometimes, it's about protecting her reputation or her place at Hogwarts too.
One common theme is redemption. Sirius has had a troubled past, and Hermione could be seen as the one to help him fully redeem himself. Another theme is the power of love across different generations. Since they are from different age groups in the original series, the fanfictions might explore how love can bridge that gap.
Some fanfictions might explore the magical world's reaction to such an unusual pairing. For example, how would the other characters like Harry or Ron react? Or what about the wizarding society's views on this relationship? This adds an extra layer of complexity and drama to the story, making it more interesting to read.
One common theme is friendship. Hermione, being a kind - hearted and responsible character, forms a unique friendship with Scorpius as she helps raise him. This friendship often bridges the gap between different houses or families in the wizarding world.
One common theme is redemption. Draco is often seen as a character who has the potential to be better, and Sirius' influence is a way for him to find that better path. Another theme is family. It shows that family doesn't have to be just blood - Sirius becomes like a father figure to Draco.
One common theme is the idea of mentorship. Sirius, being an older and more experienced wizard, can guide Hermione in different aspects of the wizarding world. For example, in many fanfics, he helps her understand the Marauders' era better.
One common theme is mentorship. Sirius can be seen as a mentor to Hermione, guiding her with his more worldly wizarding knowledge. Another theme is the idea of family. Since Sirius is an outsider in his own family, and Hermione has Muggle - born status, they form a kind of surrogate family for each other.
One common theme is the exploration of an unconventional friendship. Sirius and Hermione come from different generations in the wizarding world, so their friendship defies the norms.
