Well, perhaps they begin by magically cleaning the flat first. After that, they might decide to put up some pictures on the walls. Sirius could bring out some old photos of Harry's parents that he's been saving. They also might use some spells to create floating candles for a cool lighting effect. And they could make a cozy corner with a big, plush armchair and a bookshelf filled with Harry's favorite books.
They might start by choosing a color scheme. Maybe they'd go for Gryffindor colors like red and gold to show Harry's house pride. Sirius might use his magic to move the furniture around easily while Harry decides where to put his Quidditch memorabilia. They could also add some protective enchantments around the flat while they decorate, making it a safe and cozy place.
I think Sirius would be the one. He's been in and out of different places, from his family's old manor to Azkaban. He has a broader view of what's possible. He could suggest things like using a time - turner as a decorative piece (in a non - functional way) or creating a ceiling that mimics the night sky at Hogwarts, which are very creative ideas compared to what Harry might come up with.
Sirius has a wild side. He could suggest having a room dedicated to pranks, filled with things like extendable ears and dungbombs (just for fun, not for actual use). Harry, being responsible, would be more concerned about the security of the flat. He'd make sure the doors and windows have strong locking spells. He might also want a study area that is quiet and organized for his studies and future plans.
Yes, there are likely to be such fanfictions in the vast world of fanfiction. Many fans like to create alternate family relationships and storylines for their favorite characters.
Yes, there are likely some fanfictions with this concept. Fanfiction writers often come up with creative and alternative family relationships for characters. You can search on popular fanfiction websites like Archive of Our Own or Fanfiction.net using relevant keywords to find such stories.
One reason could be Harry's impulsiveness. Harry often jumps into dangerous situations without thinking, and Sirius, being his godfather and having a protective nature, would shout at him to make him realize the risks. For instance, if Harry decides to go after a Death Eater alone.
Sirius would have a big impact on Harry's understanding of family. Harry has always longed for a real family, and Sirius would show him what a loving and supportive family can be like. This would make Harry more open - hearted and less guarded. He would also be more likely to forgive those who have wronged him in the past, as Sirius might teach him the value of forgiveness. Moreover, Sirius' love for adventure could make Harry more adventurous in his exploration of magic and the wizarding world.
It could be Draco Malfoy. In some fanfictions, they put aside their differences and develop a relationship. Sirius would be very surprised as he used to see Draco as an enemy. But seeing Draco's growth and his love for Harry could change Sirius' view.
