Well, in the original, Remus was one of the many mentors to Harry. However, if they were mates in the fanfiction, their relationship would be more equal. They would rely on each other more. Harry would probably be more involved in Remus' personal life, like helping him deal with his werewolf side in a more intimate way. And Remus would be more protective of Harry in a possessive way, not just as a teacher or friend.
In the original story, their relationship was more of a teacher - student and friendly one. But as mates in the fanfiction, they would be much closer emotionally. They might share secrets that they wouldn't share with others. For example, Harry could confide in Remus about his real feelings towards the Dursleys much earlier.
In the original story, Harry and Remus had a relationship based on the Order of the Phoenix and the fight against Voldemort. But in the fanfiction, as mates, their relationship could start much earlier. Maybe they meet as children in some magical way. Their relationship would develop with a stronger emotional and magical connection. Remus could be the one to introduce Harry to different magical cultures and traditions that were not part of the original story, and Harry would bring a new sense of purpose to Remus' life.
Well, in the original Harry Potter series, Harry was focused on fighting Voldemort and his adventures were mainly centered around that. However, in this fanfiction, since Fem Harry is Bill's mate, their relationship would develop with a focus on building a life together. Their relationship might develop through shared interests in things like exploring different parts of the wizarding world that are not related to the main battle. And the way they communicate would be different. Fem Harry might be more open about her emotions with Bill compared to the original Harry who was often more reserved. Also, their relationship would be influenced by the Weasley family traditions and values in a much deeper way as they are mates, not just friends or comrades.
At first, it might be a bit awkward. Teddy has only heard stories about Remus, and Remus is seeing this young man who is his son in a way he never expected. But as they start to talk, they would find common ground in their love for magic and their experiences at Hogwarts.
One way could be through a series of shared adventures. For example, Hermione might be working on some complex magic research related to werewolves, and Remus, being a werewolf himself, could offer unique insights. This common ground could gradually lead to a deeper connection between them. They could start as colleagues in the magical world of academia or research, and as they spend more time together, they realize they have feelings for each other.
In the original story, Hagrid is more of a secondary figure in Harry's life. But if he was raising Harry, their relationship would be much more paternal. Hagrid would be the one Harry turns to for all his problems, big or small. Harry would probably be more influenced by Hagrid's love for magical creatures and have a deeper understanding of them from an early age.
Often, Harry's character development in fanfiction related to Lupin can involve him learning about the importance of loyalty and friendship in a more complex way. Remus Lupin may develop by coming to terms with his own past traumas more fully. For example, through his relationship with Harry, he could face and overcome some of the self - loathing he has due to his lycanthropy. This mutual growth can be seen in how they interact and support each other in different situations.
One common theme is mentorship. Lupin being an older and more experienced wizard often acts as a mentor to Harry, guiding him through his struggles. Another theme is the idea of found family. Given Harry's lack of a proper family, Lupin can become like a surrogate family member to him in these fics.
In fanfiction, their relationship could develop in a more friendly way. Instead of just being acquaintances in the original story, they could become true friends. They might start training together, sharing their knowledge of martial arts and life experiences.
Well, if Cedric survived, their relationship could become more of a mentor - mentee situation in reverse. Harry, having faced Voldemort multiple times, could teach Cedric about the true nature of dark magic and how to defend against it better. Cedric, on the other hand, could teach Harry about the importance of patience and fairness which are Hufflepuff traits.
Well, in Hogwarts, Remus Lupin's relationship with Hermione could develop in an interesting way. Remus would be drawn to Hermione's thirst for knowledge. He might start by inviting her to join some of his after - class study groups. This would give them more time to interact. Hermione would be intrigued by Remus's deep understanding of magic. As they spend more time together, Remus might share some of his personal experiences with her, which would make her see him in a different light. Eventually, they could find themselves having feelings for each other. They might even have secret meetings in the Room of Requirement, away from the prying eyes of the other students and teachers.
In the fanfiction, their relationship would be much more intense and instinctive. Instead of just being friends or acquaintances as in the original series, they would have an unspoken connection. For example, they might be able to sense each other's emotions from a distance. If Bill was in danger while on a mission far away, Harry would feel a sense of unease or even pain without really knowing why at first. Their relationship would also involve a lot more secrecy because it's not a normal type of relationship in the wizarding world.
