What are some possible reactions of Harry Potter when he reads about his sister in fanfiction?

He might be really excited. Fanfiction can offer new and different storylines about his adventures in the Digimon world. He could find some ideas really cool and might even get inspired to think about his own experiences in a new light.

Luna would be very open - minded. She might see the fanfiction as just another form of magical thinking. She could find the wild and imaginative ideas in the fanfictions quite endearing and might even start to incorporate some of the concepts into her own unique view of the wizarding world.

She would probably be furious at first. Harry is known for her strong will, and being forced into a marriage, especially with Draco, would go against everything she believes in. She might try to fight it directly, using her magic skills to break free from whatever is forcing this marriage.

She might be surprised at some of the creative interpretations of her son's story. For example, if there are fanfictions that explore different relationships for Naruto that she hadn't considered before, she could be taken aback.

He could be shocked. After all, he may have thought his parents were long gone or never expected to meet them.

He could also be shocked into momentary silence. His first sight of Harry might bring back a flood of memories, both good and bad. Maybe he freezes for a second, his mind racing with thoughts of Lily, Harry's mother, and how things could have been different. Then he quickly composes himself and tries to hide his inner turmoil behind his usual stern facade.

Another possibility is that Lucius could be initially confused. He might not understand what he's seeing at first. After all, Harry and Draco are supposed to be enemies in the general wizarding world view. He could stand there for a moment, trying to process what's going on before taking any action.

Sirius may also be angry at first. Given his protective nature towards Harry, if he misinterprets the situation as Draco causing trouble for Harry, he would likely step in assertively. But if it's a situation where Harry and Draco have a more positive or friendly interaction in the fanfiction, Sirius would have to re - evaluate his initial reaction.

Harry Potter might be a bit surprised. He'd probably think it's strange that people are writing about his friends' and his own relationships in such a different way. Hermione would likely be very interested in the writing style and how the authors are creating these new relationships. She might even take notes to improve her own writing. Ron would just laugh it off most of the time. He'd find it a bit odd but also funny.

One possible reason could be jealousy. Maybe the sister is getting more attention from their parents or at Hogwarts. For example, if she is a star student and Harry feels overshadowed.
