Dumbledore would be in a difficult position. On one hand, Harry is an important part of the fight against Voldemort and Dumbledore respects his views. On the other hand, Snape has been a crucial asset in the battle against the Dark Lord. Dumbledore might set up a series of investigations or observations. He could ask other teachers to keep an eye on Snape's behavior in the classroom and around the school. He would also encourage Harry to give Snape a chance to improve or explain himself. Dumbledore's reaction would be a complex one, as he has to balance the needs and concerns of both Harry and Snape while also considering the safety and well - being of Hogwarts.
Dumbledore would probably first have a long conversation with Harry. He would want to understand Harry's concerns thoroughly. Then, he would talk to Snape privately. Dumbledore is very protective of Hogwarts and its students. If he found that Snape's actions were truly endangering the students or the school's harmony, he might consider some form of disciplinary action, but firing Snape might not be his first option. He would also weigh Snape's contributions to the Order of the Phoenix and the fight against Voldemort. He has a lot of faith in Snape, but he also respects Harry's instincts and would take his feelings into account.
In such a fanfic, perhaps Harry discovers some long - hidden, damning secret about Dumbledore. Maybe it's related to Dumbledore's past actions with Grindelwald. Harry, being the honest and justice - seeking person he is, feels compelled to expose this secret, which then leads to Dumbledore being fired from his position at Hogwarts.
One possible reason could be Snape's unfair treatment of Harry and his friends. Snape often showed blatant favoritism towards Slytherin students and was overly harsh on Gryffindors, especially Harry. This constant bias could lead Harry to want him fired. Another reason might be Snape's connection to the Dark Arts. Harry, having faced Voldemort, might be worried about Snape's knowledge and use of dark magic within Hogwarts. Also, Snape's generally unpleasant demeanor towards students could be a factor. His sarcastic remarks and cold attitude might make Harry think that he is not a suitable teacher for Hogwarts students.
It could be Voldemort or his followers. They might see Dumbledore as a major obstacle in their path to power. So they could manipulate Harry, perhaps through some mind - control magic or by spreading false rumors, to get Dumbledore fired. By removing Dumbledore, they hope to gain more control over Hogwarts and the wizarding world in general.
I don't have any novels about the era of the Big Four. However, if Harry Potter and Severus, Snape, Albus, and Dumbledore were to travel back in time to the era of the Big Four, then the story might involve the history, politics, culture, and other aspects of the Wizarding world. At the same time, there might be other characters and storylines. Can you give me more information? I will do my best to help you.
Snape might be given a warning by Dumbledore at first. Just a simple 'stop this behavior or else' kind of warning.
Harry could also be angry. Despite understanding Dumbledore's generally good intentions, being tied to a bed against his will is a violation of his freedom. He might struggle against the restraints and demand to be released immediately, especially if he feels that Dumbledore is overstepping his boundaries.
One great 'Harry Potter wants Snape' fanfiction is 'The Unlikely Bond'. It explores a scenario where Harry realizes Snape's complex nature early on and tries to form a different relationship with him. It delves deep into their emotional exchanges and how it could potentially change the course of the story in Hogwarts.
Well, perhaps one of the other teachers might have noticed Snape's behavior towards Harry and reported it to Dumbledore. It could also be that Dumbledore, being as perceptive as he is, noticed Snape's extra harsh treatment of Harry during their interactions in the corridors or in class.
Snape would probably be very conflicted. On one hand, he has a long - standing grudge against James Potter, Harry's father. But on the other hand, he loved Harry's mother, Lily. So, he might be cold at first, but then his sense of protecting Lily's son could kick in. He would likely be very strict with Harry, as he is with all his students, but also secretly keep an eye on him to make sure he's safe.
At first, Harry is likely to be angry. He might feel that Snape is being unfair and targeting him. Harry has a strong sense of justice, and when he believes he's being wrongly punished, he'll be resentful.
