I sincerely hope there is no such fanfic. Rape is an extremely serious and immoral topic that should not be used in any form of fictional creation, especially in the context of fan - made works related to popular characters like Harry and Ron.
A possible plot development could be that Snape, out of guilt and a sense of responsibility, decides to mentor Harry more closely. He could introduce Harry to some powerful magical artifacts or spells that could help Harry regain his confidence. Meanwhile, Harry might start to see Snape in a new light, and their relationship could evolve into a more trusting and deep - rooted bond, leading to many more twists and turns in the story as they face other challenges together.
In this kind of fanfiction scenario, Snape might initially be conflicted. On one hand, he has his long - standing dislike for James Potter, Harry's father. But on the other, his sense of duty as a Hogwarts professor could kick in. He might reluctantly start to heal Harry, all the while muttering under his breath about how much trouble Harry always seems to get into, just like his father. Then, as he heals Harry, he might start to see some of Lily, Harry's mother, in him and soften a bit.
One possible plot development could be Harry's struggle with his mental health. He might experience symptoms like depression, anxiety, or post - traumatic stress disorder. Another could be his search for justice or revenge against the perpetrator. He may also face challenges in his relationships as he tries to come to terms with what happened.
Definitely Dumbledore, if he were still alive. He was always a guiding figure for Harry. He could use his wisdom and influence in the wizarding world to ensure that Harry gets the justice he deserves. Also, Neville could be an ally. Neville has grown into a strong and brave character, and he would stand by Harry, offering his loyalty and friendship during this difficult time.
One way is through strict community guidelines. Fanfiction communities should have clear rules that prohibit any form of content involving non - consensual and violent acts like rape. These rules need to be actively enforced.
He would probably be in shock. Snape has spent so much time around Harry in one way or another throughout his years at Hogwarts. His immediate reaction could be disbelief. He might stand there frozen for a moment, unable to process what he's seeing. Then, the full weight of the situation would hit him, and he could break down in a rare display of raw emotion.
He could be secretly worried. Snape might use his knowledge of potions and dark magic to try and find a cure or at least a way to stop the bleeding. He may also be conflicted, as his past relationship with Harry and his loyalty to different sides in the wizarding world play a role in how much he wants to help Harry.
In the fanfiction world, if Snape found out Hermione had been raped, he might first be filled with a cold rage. He could use his skills and influence to seek out the perpetrator. Given his complex character, he would likely take justice into his own hands in a very Snape - like way, perhaps using his knowledge of the Dark Arts to exact revenge while also trying to protect Hermione from further harm and the public eye.
One place to start looking for the missing fanfiction could be on large fanfiction platforms like FanFiction.net or Archive of Our Own. They have extensive collections of Harry Potter fanfictions. Check their search functions, maybe filter by characters (Snape and Harry Potter) and relevant tags.
