Often, there's a theme of overcoming prejudice. Severus is often misjudged, and in these fanfics, Hermione, Ginny, and Remus might initially have their doubts about him. But as the story progresses, they see beyond the surface and learn to work together. Also, the fanfics might involve a magical mystery that only their combined efforts can solve. It could be something related to an ancient spell or a hidden magical artifact that has the potential to change the wizarding world.
There's a fanfic I read once where they all end up in an alternate magical realm. In this 'hermione and remus and ginny and severus fanfic', they have to learn to trust each other quickly to survive. Hermione is the first to reach out to Severus, which surprises everyone. Ginny's quick thinking and Remus' werewolf abilities also play crucial roles in their adventure. It was really interesting to see how the author developed their relationships in such an extreme situation.
Well, a lot of 'Hermione and Remus' fanfics have the theme of acceptance. Remus is a werewolf, and Hermione has to accept his condition. In return, Remus accepts Hermione's Muggle - born status. Another theme is the power of intelligence. Hermione's intelligence and Remus' wisdom combine in many stories to solve problems. Also, the theme of breaking boundaries is common. They often break social or magical boundaries in these fanfics to form their relationship.
Often, there's a theme of the unexpected. Their relationship in fanfic is usually not what one would expect given their roles in the original books. Also, the theme of mentorship can be found. Hermione might learn from Severus' deep knowledge of magic, and he could learn from her modern - thinking. There's also the theme of hidden feelings, as they initially seem at odds but may have deeper, unspoken emotions for each other.
One of the themes is the exploration of their different personalities. Ginny is more outgoing and sporty, while Hermione is bookish and logical. Fanfics play with how these differences can either create friction or lead to a great partnership. Also, the theme of loyalty comes up a lot. They are loyal to their friends and Hogwarts, and this loyalty is often a driving force in the stories.
A common plot element is the discovery of Hermione's situation. Usually, Remus somehow becomes aware that Hermione is in danger or being abused. It could be through his own observations, or maybe Hermione reaches out to him for help.
One common plotline is a redemption arc for Severus. He may be influenced by Hermione's kindness and intelligence to turn away from his darker tendencies. Another is a power struggle between Hermione, representing the new wave of Hogwarts students, and Lucius, who stands for the old pure - blood ways. And often, there's a love triangle or some form of complex relationship dynamics among the three.
The exploration of intellectual connection is also quite common. Hermione is highly intelligent, and Severus is no slouch either. Fanfics usually show how their shared love for knowledge and magic forms a strong foundation for their relationship. They might bond over potions or some other complex area of magic study.
Character dynamics are a key element. Hermione's intelligence often plays a role in how she interacts with the more complex Remus and Snape. For instance, she might be the one to bridge the gap between their different personalities.
One popular trope is the 'enemies to lovers' where Severus initially dislikes Hermione but gradually falls for her. Another is the 'teacher - student relationship' dynamic which adds an element of forbidden love. And the 'redemption arc' for Severus through his relationship with Hermione is also common.
Cultural differences are also often explored. Hermione, being from a British magical background, may face some cultural shocks in an American magical community. This can create a lot of tension and also opportunities for character growth. For instance, different magical traditions and social hierarchies between the two countries can be a source of drama.
