Snape would be appalled. He has a deep connection to the world of Harry Potter, and the idea of a rape romance fanfiction is so far removed from the values of the wizarding world he knows. He might initially be in disbelief, thinking it was some sort of dark joke or a misunderstanding. But once he realizes it's real, he would likely feel a mix of anger towards the creator and sadness that such a thing exists in relation to a world he cares about.
Snape would be deeply shocked and disgusted. Given his own experiences and the values he holds, finding Harry in a rape - related romance fanfiction would be like a blow to his perception of the world around Harry. He may initially be in disbelief, but then his anger would rise. He might try to find out who created such a disturbing fanfiction and perhaps try to put an end to it, as it goes against everything he believes in and the world he is a part of in the original Harry Potter series.
In the fanfiction world, Snape might be initially shocked. He has a complex relationship with Harry. He could feel a sense of protectiveness that he rarely shows openly. He might use his skills and knowledge to find the perpetrator and seek justice for Harry.
This is a very disturbing scenario. In the context of the Harry Potter universe which is generally about magic, friendship, and good vs. evil, such a concept goes completely against the spirit of the original work. Snape would likely be extremely horrified and disgusted, given his complex relationship with Harry. He might see it as a desecration of the students and the world he knows.
It could cause a huge uproar. Snape is a respected figure in the wizarding world in fanfiction. His discovery of such inappropriate content would likely lead to a call for more censorship or regulation of fanfiction. People would be shocked that such a thing could exist, and it might lead to a divide between those who think it's just fictional and those who find it deeply offensive.
He would probably be furious. The blood quill was a very cruel and unjust tool used on him as a student. Discovering fanfiction about it might make him feel that his past pain is being exploited or made light of.
Snape's initial reaction would be one of disbelief. He has his own set of prejudices and ideas, and gay romance fanfiction is far from his realm of understanding. He might snatch the fanfiction away from Harry in a fit of annoyance. But as he sees Harry crying, he might start to wonder what in this strange piece of writing has such an emotional impact on Harry. This could lead to a very awkward and tense moment between them, with Snape not knowing how to handle the situation properly.
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.
This is a very disturbing concept. In the context of fanfiction, it would likely create a huge shock for Snape's character. It goes against the moral fabric of the original Harry Potter world. However, this is a very dark and inappropriate scenario for fanfiction.
He might be quite amused. Dumbledore has a great sense of humor and an open mind. He would probably find the creative interpretations of his world and the characters he knows so well to be an interesting study of how others perceive Hogwarts and its inhabitants.
He might be quite amused. Fanfiction often takes the original story in wild and creative directions. Harry, being used to the strange and unexpected in his own life, could find it entertaining to see how fans re - imagine his adventures, relationships, and even his character traits in new and different ways.
