The Black family's reaction to reading Harry Potter fanfiction would likely be mixed. There could be those who are immediately drawn in by the unique ideas and character developments that fanfiction often presents. They might be happy to see different takes on the magical world they are part of. On the other hand, there are likely members who hold the original books in high regard and see fanfiction as a distortion of the 'true' story. They may feel that it undermines the integrity of the wizarding world as J.K. Rowling created it. There could also be some in - between, who are initially skeptical but then start to appreciate certain aspects of the fan - created stories.
Hermione would be very worried. She would likely try to convince Harry to come back, reasoning with him about the importance of family. Ron, on the other hand, might be a bit more understanding. He might give Harry some space at first but also keep an eye on him. Dumbledore, if he were still alive, would probably have a long - term view. He might let Harry go for a while, knowing that Harry needs to grow on his own, but also be ready to guide him back when the time is right.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
He may be confused at first. Fanfics can be very different from his real experiences. He might wonder why people write such things about him and his world.
Well, Harry Potter is a rather humble character. He might initially feel a bit embarrassed to see himself as the center of so many fictional stories created by fans. If the fanfic portrays him as a hero in new adventures, he would probably be honored. However, if it misrepresents his friends or the values he holds dear, he could be a bit indignant. He would likely approach it with an open mind but also with a sense of protectiveness towards his own story and those he loves.
Well, the wizarding world's reaction would be mixed. Some of the more open - minded wizards might be curious or even a bit accepting. But most, like the pure - blood families who are very traditional, would be horrified. The Potter family would become the talk of the wizarding world, and it would be difficult for Harry, Hermione, and Ron to carry on as normal at Hogwarts. There would be a lot of whispering and stares everywhere they go.
Harry might initially be shocked and confused. He's used to Hogwarts being his safe haven, so when it turns against him, he'll be at a loss. He may try to prove his innocence by finding evidence or confronting those who are spreading lies.
The headmaster might be a bit surprised at first. He would likely respect Harry's opinion, though. He has always valued Harry's thoughts and feelings. He may start to think about the implications of fanfiction on the wizarding community and how it might affect the students and the overall perception of Hogwarts.
As time goes on, Harry could start to explore what it means to 'please' Sirius. He might recall their past relationship, the things Sirius likes and dislikes, and try to use that knowledge to his advantage. He may also feel a sense of loyalty towards Sirius that, despite the odd circumstances, makes him more accepting of the situation. For example, he might remember Sirius' love for adventure and try to engage in some magical adventures with him in a way that 'pleases' him.
