What could be the plot development when Harry Potter finds out he is abused in fanfiction?

He might be shocked at first. Then he could feel a strong sense of protectiveness towards Harry. Maybe he immediately tries to find ways to keep Harry safe from further harm, like staying closer to him at all times.

Well, Bill could be shocked at first. But then he would likely become very protective. He may take Harry to a safe place, like the Burrow, and gather his family around to support Harry. He would also probably try to find out more about the abuse, like who was behind it and for how long it had been going on. He'd be determined to make sure it never happened again.

Sirius would likely be extremely angry. He already has a protective streak towards Harry. He might immediately confront those he suspects of the abuse, whether it's the Dursleys or others at Hogwarts. He would probably also try to remove Harry from the situation as quickly as possible.

He might be filled with rage. James Potter was a loving father figure in his own right. So, when he finds out about Harry's abuse, he could immediately seek to confront the abuser. He would want to protect Harry at all costs and might use his magical skills to ensure Harry's safety.

In some fanfics, Harry could find out he has distant relatives from the Potter family who live in a far - off land. These relatives could be part of a different wizarding culture. When Harry meets them, he gets to learn about different types of magic and different ways of living in the wizarding world. He might also discover that his family has a much bigger role to play in the overall wizarding history than he thought.

One possibility is that Narcissa would try to use her influence within the pure - blood society. She could spread the word among the more reasonable pure - blood families about Harry's situation. This might lead to some sort of support network being formed for Harry, even if it has to be done in secret to avoid Voldemort's wrath. She might also try to subtly nudge Draco into being nicer to Harry, which would be a big change in their relationship.

One possible plot development could be Sally's intense anger and determination to protect Percy. She might seek justice against the abuser, which could lead to a showdown in the fanfic's world. Maybe she teams up with Percy's friends to expose the truth.

The story might involve the child being from a past relationship that Harry had forgotten due to some spell or memory charm. As he finds out, he has to face the mother of the child as well. This could lead to a complex web of relationships and emotions. He might struggle with whether he can be a good father, considering his own difficult upbringing without his parents.

Maybe Harry discovers he was secretly adopted by the Weasleys all along. So he has to adjust to this new reality and learn about his true family ties within the Weasley clan.

Ginny may first be shocked and then filled with anger. She might immediately go to her family, like the Weasleys, for help. They together could come up with a plan to rescue Harry from the situation. She would also be by Harry's side constantly, providing him with emotional support, as she has deep feelings for him and wouldn't stand to see him suffer.
