In this kind of fanfiction, it often shows Ginny's shock and the complex emotions she might have. She might be worried about Harry's fate, as being a Horcrux means he is tied to Voldemort in a very dangerous way. This discovery could lead to her trying to find a way to break the Horcrux connection without harming Harry.
In this type of fanfiction, the relationship between Harry and Snape can be re - imagined. Snape was Harry's teacher for Occlumency in the books, but often their interactions were tense. Fanfic writers may change this dynamic. They could have Snape be more patient or Harry be more receptive, which would lead to a different kind of mentorship and a new understanding between them.
One interesting lesson could be table manners in the wizarding world. There might be specific ways to hold a wand while dining or proper incantations to say before and after a meal. Another could be how to address different levels of wizards and witches, like the proper title for a powerful elder wizard. And perhaps the correct way to enter and exit a magical room or building, which could involve specific spells or gestures.
Perhaps it's a magical crystal that enhances his ability to communicate with magical creatures. This would be quite unique as it would give him an edge in dealing with things like thestrals or unicorns, and open up new storylines in the fanfiction. Harry could use this crystal to understand their needs and gain their help in various situations.
Obviously, Harry is a main character. Hermione might also be there as she is good at potions and can help Harry. And Snape could be a prominent figure as he is the potions teacher.
Well, it could be about Harry exploring traditional or ancient magic methods, perhaps things that were long forgotten in the wizarding world. Maybe he discovers old spells, or ways of divination that were practiced ages ago.
Harry Potter himself is, of course, the central character. Snape is also very common as he is Harry's teacher in occlumency in the original books. Hermione and Ron often make appearances as well, as Harry's best friends. They might be involved in helping Harry learn or just be there for moral support.
This phrase 'everyone learns harry abused fanfiction' is rather unclear without more context. It could be about the spread of knowledge regarding a fanfiction where Harry is abused. It might be part of a larger conversation about the ethics of fanfiction. For example, some might argue that depicting a beloved character like Harry in an abused state is inappropriate, while others might see it as a creative exploration of darker themes. It could also be related to how quickly information spreads within the fan community, and how such a story might impact the overall perception of the Harry Potter fandom.
