One way this could develop is that Snape, initially reluctant, gradually realizes Harry's unique needs due to his autism. He might start by being less harsh in his criticism during potions class. For example, instead of scolding Harry for his mistakes, he begins to patiently guide him. This newfound understanding could lead to a bond between them, and Snape could use his vast knowledge of magic to help Harry find ways to control his magical abilities better in relation to his autism, like developing a spell or potion to ease his sensory overload during chaotic magical situations.
In this fanfiction, Snape could help Harry by introducing him to the concept of using magic to manage his autistic traits. Maybe he shows Harry how to create a quiet, calming magical space where he can retreat when overwhelmed. Snape, having his own complex past and being a skilled wizard, could also mentor Harry in understanding his emotions better. Since Harry may struggle with social cues due to his autism, Snape could subtly teach him how to interact more effectively with his peers at Hogwarts. This could involve using magic to enhance his perception of non - verbal signals.
Snape might face the challenge of his own biases. He has had a long - standing dislike for Harry's father, and this could initially cloud his ability to help Harry. Also, the wizarding community may not fully understand autism, so Snape could face resistance or lack of support when trying to implement special accommodations for Harry.
Snape's character development in these fanfictions is quite interesting. At first, he might be helping Harry out of a sense of obligation to Lily. But as time goes on, he starts to form a unique bond with Harry. His interactions with Harry force him to confront his own prejudices and grudges. He becomes more empathetic towards Harry's situation, which is a big change from his initial coldness. For example, in some stories, he begins to understand Harry's loneliness and tries to offer some form of companionship, which is a huge step for a character like Snape.
One possible reason could be Snape's sense of duty to protect Hogwarts students in general. Even though he dislikes Harry, he might put aside personal feelings to ensure the safety of a student in a dangerous tournament like the Triwizard Tournament. Another reason could be Dumbledore's influence. Dumbledore trusts Snape and may have asked him to keep an eye on Harry during this event.
One possible plotline could be that Harry discovers he is in this unexpected mpreg situation and is initially terrified and confused. Snape, despite their past differences, steps in to help because he realizes Harry has no one else to turn to. Snape could use his knowledge of potions to ease Harry's physical discomfort during the pregnancy.
In these fanfictions, their relationship often starts with suspicion. Hermione is wary of Snape due to his reputation, and Snape initially sees Hermione as just another student. But as he starts to help her, like when he gives her advice on how to deal with a particularly tricky magical creature in Care of Magical Creatures class, she begins to see a different side of him. Their relationship then slowly develops into a mutual respect as they work together on various tasks around Hogwarts.
In some versions, Snape might use his knowledge of the Dark Arts to expose the wrongdoings of those who have wronged Harry. For example, if there are Death Eaters or bullies in Hogwarts who target Harry, Snape could reveal their secret plans or actions that are against the school rules or the wizarding law.
In this fanfiction, it might be that Snape sees Harry in a vulnerable state during winter break. Maybe Harry is being bullied by some Slytherins even during the break at Hogwarts. Snape, despite his usual dislike for Harry, steps in to protect him. This action could start to change Harry's perception of Snape, and they could form an unlikely alliance. As time passes, Snape could start to share some of his own experiences with Harry, which helps Harry grow not just as a wizard but also as a person.
At first, it's likely to be very tense. Snape has always had a grudge against Harry because of his father. But as they live together, they start to see each other's true selves. Harry might see Snape's vulnerability and intelligence, while Snape might see Harry's courage and determination that are different from James's arrogance.
Often, it starts with intense dislike. Snape is constantly critical of Harry in class, deducting points for the slightest mistakes. Harry, in turn, sees Snape as a bully. As the story progresses, there might be small moments of grudging respect, like when Harry realizes Snape's intelligence in potions, but the overall hatred remains for a long time.
At first, it could be very tense. Harry might be reluctant to submit, but as time goes on, he starts to see Snape in a different light. This could lead to a grudging respect. For example, Snape might show Harry some advanced potions techniques that no one else has taught him, which makes Harry realize Snape's value.
