Dumbledore, if he were still alive in the fanfiction, would see Harry's death as a necessary part of a grand plan, but still feel a great sense of sorrow. He might use Harry's death as a rallying point for the wizarding community to come together and fight against the remaining dark forces. And Snape, in his own way, might feel a strange mix of relief that his long - held secret is safe, but also a sense of loss for the boy who was a key part of the battle against Voldemort.
The Weasley family would also be greatly affected. Mrs. Weasley would surely mourn Harry as one of her own. Ginny, who had feelings for Harry, would be heartbroken. She might become more fierce in her pursuit of justice in the wizarding world. And the other students at Hogwarts, like Neville, would be inspired by Harry's sacrifice to step up and be braver in the face of danger.
Dumbledore would feel a great sense of loss and guilt. He had always seen Harry as the key to defeating Voldemort. His reaction could be to go into seclusion for a while to think about what went wrong. The other Hogwarts professors would be in shock. Hagrid would be heartbroken and might even leave Hogwarts in his grief. And the Death Eaters would be jubilant, but also a bit wary as they know that there could be unforeseen consequences to Harry's death.
If Gandalf were to enter the world of the young Harry Potter fanfiction, the Hogwarts professors would have mixed reactions. Dumbledore would be intrigued and see Gandalf as an equal, interested in sharing magical knowledge. Snape, on the other hand, would be more guarded and perhaps a bit jealous of Gandalf's presence. The students would be in awe. Harry would see Gandalf as a new source of guidance and protection. Hermione would want to pick Gandalf's brain about all the different kinds of magic he knows. And the overall reaction in the fanfiction world would be one of excitement and a bit of chaos as everyone tries to figure out how Gandalf fits into their world.
Ron would be completely shattered. Harry was his best friend, and he would likely feel guilty for not being able to protect him. He might become reckless in his attempts to avenge Harry. Hermione would be grief - stricken but also determined. She would pour herself into finding a solution to the mess left behind. Ginny would be heartbroken. She might initially withdraw but then become a strong advocate for justice, using her own skills and magic to fight against Voldemort's regime.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
The Auror department would likely be in chaos. There would be a lot of self - reflection and blame - sharing. Some might question the safety protocols of their missions. His death could also lead to a decrease in morale among the younger Aurors who looked up to him. In the wider wizarding world, there would be fear as Harry was seen as a great protector. People might start to worry more about their safety.
Hermione would be heartbroken as well. She would likely try to find a way to bring Lupin back, delving deep into the library's restricted section for any possible spells or solutions. She would also be the one to comfort Harry and Ron, using her logic to try to make sense of the senseless loss.
Harry is usually completely devastated. He might go into a state of shock at first, unable to believe that Hermione is gone. Then he could be filled with anger, either at himself for not being able to protect her or at the situation that led to her death.
Hermione would likely be devastated. She might go into a deep state of mourning, but also use her intelligence to try and figure out what led to Harry's death. Ron would be angry and heartbroken at the same time. He'd probably want to seek revenge if there was someone or something responsible.
Hermione would be extremely curious. She would immediately start researching it, trying to figure out its mechanics and where it came from. She might even try to find a way to improve it or adapt it to the wizarding world's technology.
Dumbledore would likely be very accepting of Stitch. He has a great understanding of all kinds of creatures and beings. He would see Stitch's potential for good and might even try to find a place for him at Hogwarts. Snape, however, would be more skeptical. He would keep a close eye on Stitch, worried that he might disrupt the order of the school or cause harm to the students. The Weasley twins would probably find Stitch hilarious and would want to play pranks with him or use his unique abilities for their own mischievous plans.
