Sometimes, their friends like Sirius Black or Remus Lupin might also be important characters. They could be involved in the couple's life, perhaps helping them out in difficult situations or just being there for moral support.
Sometimes they are. Fanfiction is all about creativity and different authors have different takes. Some stories show them getting married, while others might explore different paths for their relationship.
Definitely, Teddy Lupin could be in there. He could be a cool older cousin - like figure to Rose, showing her different aspects of the wizarding world that she might not have known. Then there's Astoria Greengrass, Scorpius's mother. Her backstory and how it affects the couple's relationship can be explored. And Blaise Zabini could be a side character, perhaps involved in some of the social events that Rose and Scorpius attend as a married couple.
Sure. Fanfiction often takes established characters and relationships and turns them on their head. The idea of Harry Potter marrying Lily, while not in line with the source material, might be explored in some fan - created stories. It could be a really strange and interesting concept to read about, especially if the writer can come up with a believable backstory that somehow makes this relationship work, like through some kind of magical time - bending or parallel universe scenario.
There's a fanfic called 'Snape and Lily: A Married Life'. It details their daily life after getting married. It's quite heartwarming as it shows how they support each other. The author has done a great job of portraying their love and the challenges they face together in a believable way.
There could be. Fanfiction writers like to explore unusual pairings. But this one is really a stretch as Voldemort tried to kill Lily and her family. In the world of fanfiction, though, anything is possible. Some writers might be interested in exploring how such a relationship could potentially develop in an alternate universe, perhaps where Voldemort had a different upbringing or motivation.
Remus Lupin would be a great addition. He's another one of James' friends. He could offer them wise advice, especially when it comes to the more difficult aspects of their relationship or the challenges of living in the wizarding world. He might also help them out during full moons.
Obviously, James and Lily are the main characters. But other characters could also be included. For instance, Sirius Black, as James' best friend, might be a regular presence. He could be the fun - loving, trouble - making friend who often drops by their house unannounced. Then there's Remus Lupin, who could be a more calm and wise friend offering advice to James and Lily on their married life. And of course, Petunia, Lily's sister, might be a part of the story, perhaps causing some family - related drama.
In some fanfictions, Severus might become more open and less brooding when married to Lily. His love for her gives him the confidence to be more social. Lily, on the other hand, could become more patient as she understands Severus' past traumas better.
Lily could be an ordinary Pokemon fan who has a special love for fan - made Pokemon stories. Maybe she's a young girl who has been into Pokemon for a long time and has discovered the world of fanfic as a way to expand her love for the franchise. Or she could be a more prominent figure within a specific Pokemon fan community, known for her enthusiasm for fanfic.
