How would the characters in Hogwarts react when watching Harry's worst memories in the fanfiction?

They would probably be very emotional. Some of them might cry, especially Molly, seeing all the pain Harry has been through.

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.

Usopp might be inspired to be braver. When he watches Luffy's memories, he could see how Luffy fearlessly faces powerful enemies. This would make Usopp want to overcome his own cowardice and be more like Luffy. And Robin, she would gain more insights into Luffy's kind heart. She might see how Luffy has always been inclusive and accepting of everyone, which would make her feel even more at home in the crew.

Some characters might be critical. Elsa, being a powerful and responsible character, might not like it if the fanfiction misrepresents her in a way that goes against her values. She might think that the writers should be more respectful of her character arc and not make her do things that are completely out of character just for the sake of a wild story. However, at the same time, she might also appreciate the creativity in some parts.

Some would be intrigued. Captain America, being an open - minded person, might be interested in seeing different interpretations of their team dynamics. He could even gain new insights about his relationships with his fellow Avengers through the fanfiction.

Well, the characters in Hogwarts would have a wide range of responses. Neville, for example, might be a bit shy about it at first but then get really into it if he finds parts that resonate with his own experiences. The Weasley twins would probably find ways to make fun of or use elements of the fanfiction in their pranks. The ghosts in Hogwarts might have a more detached view, but they could still be interested in how the living students react to it. And Harry himself? He might be a bit embarrassed at first, but also curious to see how others have imagined his childhood.

They'd be shocked and maybe even emotional. Discovering each other's hidden thoughts and past experiences could lead to a deeper understanding and stronger bonds among them.

One possible plot could be that the students and teachers at Hogwarts watch Harry's memories of facing Voldemort in the graveyard in 'Goblet of Fire'. They might be shocked and sympathetic, and it could lead to a greater understanding of Harry's burden. Another plot could involve Harry's memories of the Dementors affecting him, and as they watch, they figure out ways to help him better combat the Dementors' effects in the future.

The characters' reactions would be diverse. Snape would likely be very critical and use it as another reason to dislike Harry. He might see it as a sign of Harry's lack of respect for the wizarding world's traditions. The other students would be a mix of those who are fascinated by this strange Muggle object and those who are worried about its potential for harm. Hagrid would be confused, not really understanding what a gun is but knowing it doesn't seem right in Hogwarts. Overall, it would create a stir among the Hogwarts community and lead to a lot of discussions and speculations.

It could make Draco feel exposed and vulnerable at first. But if Hogwarts uses the knowledge from his memories to help him, Draco might develop a newfound respect and loyalty towards Hogwarts. He could see it as an entity that truly cares about him rather than just a place of learning.
