In many fanfictions where Sirius meets Remus' parents, it can be a very interesting scenario. It might be filled with tension as Sirius is often seen as a bit of a rebel. Maybe at first, Remus' parents are cautious of Sirius, given his family's reputation. But as they get to know him, they could see his true self and how much he cares for Remus.
I really like 'A Ray of Hope in the Darkness'. In this fanfic, Sirius is depressed after the events that have befallen him. Remus is portrayed as a very patient and loving character. He slowly helps Sirius heal by being there for him, and the story is full of emotional moments that will make you feel for both characters.
A good 'Remus x Sirius' fanfic with a depressed Sirius should first and foremost have a deep understanding of the characters. Sirius has been through a lot, like Azkaban, and his depression should be portrayed realistically. For example, his mood swings, self - doubt, and isolation. Remus should also be in - character, showing his loyalty and love for Sirius in a way that is true to the original series.
Friendship is a very common theme. Their deep bond as friends is often explored, how they support each other through difficult times at Hogwarts and later in life.
Another good one is 'Moonshine'. It has a really interesting take on how Remus and Sirius interact. It shows their friendship evolving over different situations, and the writing style is very captivating, making you feel as if you're right there with them.
Friendship is also a big theme. Their unique friendship, which is a blend of mischief and deep understanding, is often the focus. Fics might show how they support each other through difficult times like the war or personal struggles.
It's popular because Remus and Sirius are both very interesting characters on their own. When you put them together in a marriage, it creates a whole new dynamic. Fans are always eager to see how they interact in different situations as a married couple. And fanfiction writers can explore different aspects of their relationship like how they deal with Remus' lycanthropy or Sirius' family issues within the context of their marriage.
Sure. Fanfiction writers love to play with established characters and relationships. In a story where Harry is Remus and Sirius' son, we could see new magical abilities or inheritances coming into play. Maybe he would inherit some of Remus' werewolf - related magic in a different way or Sirius' skills in magic related to his family's heritage. It would also change the emotional dynamics, with a different kind of family support system for Harry.
The idea of redemption can also be a theme. For example, Sirius' journey to redeem himself in some fanfics after his time in Azkaban. Also, the theme of secrecy, as they have to keep some things about themselves (like Remus' condition) a secret from the outside world, which adds an element of mystery and drama to the fanfics.
