Hogwarts as a whole might have a complex reaction. The students could be divided in their feelings. Some might be outraged, feeling that it goes against the essence of the story they love. The professors, on the other hand, could see it as an opportunity to teach about the power of imagination and the fluidity of storytelling. They might encourage students to write their own responses to these fanfictions, either in agreement or in opposition, to promote critical thinking skills.
Flitwick might be quite intrigued. He loves magic in all its forms and fanfiction would show him new and different ways magic could be used in the Harry Potter world. He'd be interested in the creative spells and concepts that the fans come up with.
They would probably be shocked at first. I mean, Hogwarts reading fanfiction? It's a strange concept. But then they might be really curious about what Hogwarts is reading. They could try to get their hands on the same fanfiction to see what all the fuss is about.
Some might be shocked and sympathetic. For example, Hermione would likely be very empathetic and immediately start thinking of ways to help Harry. She might offer her support in terms of studying magic that could protect him or just be there to listen.
If Hogwarts reads Harry's death fanfiction, it could have a complex set of reactions. Firstly, the magic within Hogwarts might seem to dim a little as if in sadness. The Sorting Hat might even start to wonder what would have happened to the houses without Harry. The magical creatures in the Forbidden Forest might sense the unease. And the students who look up to Harry as a hero would be deeply affected if they were to find out that Hogwarts was 'aware' of such a dark fanfiction. It would change the way they perceive the safety and permanence that Hogwarts represents.
No, Hogwarts is a building, not a sentient being with the ability to read in the traditional sense. It has magic and a kind of awareness, but not in a way that it can pick up a fanfiction and read it.
The teachers would likely be very sympathetic. Dumbledore might nod knowingly at some of Harry's memories, especially those related to his discovery of the truth about his family and Voldemort. McGonagall could be seen with a sad yet proud look as she witnesses Harry's growth through his memories.
He could be angry. Hogwarts is a place he loves and to see it in an abused state in a fanfiction would likely make him mad.
There would be shock and disbelief. The wizarding world has always seen Hogwarts as a symbol of hope, knowledge and safety. If Harry destroys it, many would be in denial at first, thinking it couldn't be true. Wizards and witches from all over would come to the ruins, trying to figure out what had happened.
In this fanfiction, the students' reactions would be diverse. The Gryffindor students would be especially proud to have two of their house's greatest heroes as teachers. They would be full of enthusiasm in class. Some Hufflepuff students might appreciate their down - to - earth nature and the practical knowledge they bring. Ravenclaw students could be interested in picking their brains about the more complex aspects of magic they faced. Slytherin students, while some might be initially skeptical, would soon be won over by their competence. Harry and Ginny's presence would bring a new energy to Hogwarts, and the students would be at the center of this exciting change.
It could be that Hogwarts is trying to keep track of the cultural impact of the Harry Potter series. Fanfiction is a big part of the fandom culture, and Harry's death is a very significant event in the original story. By observing how fans handle this event in their own fictional works, Hogwarts (again, conceptually) can better understand the evolving relationship between the official story and the fan - created content.
