One way it could be possible is if Harry were to discover Snape's true loyalties earlier. Maybe if he found out about Snape's love for his mother and all the sacrifices Snape made for the wizarding world while still at Hogwarts. This new understanding could gradually lead to a friendship. For example, Harry could start to see Snape in a different light during a particularly difficult time at school, like when they are facing a common enemy. He might realize that Snape's harsh treatment was more out of a sense of duty and a complex past rather than pure dislike for him.
One possible plotline could be that Harry discovers Snape's past and the reasons behind his harsh behavior. For example, Harry might find out about Snape's love for his mother. This new understanding could lead to an initial truce between them. They could start by working together on a difficult potion in the classroom, with Harry being more patient and Snape being less critical. As time passes, they might find themselves sharing their thoughts about the wizarding world's future and realizing they have more in common than they thought.
Definitely. There are many ways this could be written in fanfiction. For example, they could be forced to work together on a difficult project that requires both Gryffindor and Slytherin traits. Through this experience, they see past their differences. Harry could learn about Draco's family pressures, and Draco could see Harry's courage in a new light, leading to a friendship.
One possible motive could be a misunderstanding. Maybe Snape is framed for something really bad, like a dark magic plot against Hogwarts. Harry, in his haste to protect the school and his friends, believes Snape is guilty and takes drastic action. Another reason could be if Snape accidentally endangers someone Harry loves dearly, like Ginny or Ron, and Harry's emotions get the better of him in the heat of the moment.
Sure. Fanfiction often takes existing characters and gives them new storylines. Maybe in some fanfictions, a situation arises where Harry and Snape have to work together towards a common goal, like saving Hogwarts from a new dark threat. Through this shared experience, they could come to respect and like each other, thus becoming friends.
In fanfiction, anything can be reimagined. It could be possible through creative plot devices like a hidden relationship between Snape and Lily Potter before she was with James. Maybe there was a secret encounter that led to Harry's conception, and the truth was hidden all along.
One way it could be possible is through a magical spell gone wrong. Maybe a time - traveling spell that alters their relationship. In this fanfiction, Snape could discover he has a connection to Harry that he never knew before, and his protective instincts grow even stronger.
One possible scenario in fanfiction could be that after the war, they are forced to work together on some magical project for the betterment of the wizarding world. Through this, they gradually start to understand each other's true selves, beyond their old rivalries. Draco might realize that Harry is not just the 'Chosen One' but also a person with his own fears and doubts, and Harry could see that Draco is more than just a bully.
In the original Harry Potter story, Snape and Lily never had a baby. However, in fanfiction, authors can create alternate universes. They might rewrite the story so that Snape and Lily's relationship took a different turn. Maybe Snape was able to overcome his issues earlier and confess his true feelings to Lily before she got involved with James. This could potentially lead to a different timeline where they end up having a child together.
One possibility is that the fanfic changes Snape's backstory to make him more sympathetic. Harry, being empathetic, then feels safe around him. For instance, if Snape's past is shown to be full of hardships that made him act the way he did, Harry might understand and feel safer in his presence.
One possible plotline could be that Remus and Snape are forced to work together on a special mission within Hogwarts. They initially clash due to their past differences, but as they face various challenges together, they start to respect each other more. Then, they both have a connection with a third character, perhaps a new teacher at Hogwarts. They form an unlikely alliance to protect this person from some dark forces that are emerging in the wizarding world. This new bond gradually develops into a deep friendship that has elements of a threesome relationship in terms of their shared experiences and mutual protection.
