In most of the official 'Harry Potter' lore, Harry is not Snape's familiar. However, in fanfic, the rules can be bent and rewritten. So it's possible in some very creative and non - canon fanfictions for this strange relationship to exist, but it goes against the general nature of their relationship in the original books.
In fanfiction, Snape's teaching of Occlumency to Harry Potter often takes on different twists. Some fanfictions explore Snape's inner turmoil while teaching Harry. He has to balance his hatred for James Potter, Harry's father, with his loyalty to Dumbledore's plan. This makes the Occlumency lessons a complex and emotionally charged situation. Harry, on the other hand, struggles not only with learning the difficult skill but also with his distrust of Snape.
Yes, in certain fanfictions. Fan writers like to play with the established relationships in the original 'Harry Potter' series. They might decide to make Harry Snape's son to add a new layer of drama and mystery. For example, it could change the way we view Snape's actions throughout the series, as his protectiveness towards Harry could then be seen as a fatherly instinct.
One great fanfic is 'The Prince's Tale Continued'. It delves deeper into Snape's life after the events of the original series. It shows his struggle to come to terms with his past and his role in the wizarding world. Another good one is 'Snape's Redemption'. This fanfic focuses on how Snape tries to make amends for his past actions towards Harry and the others. It gives a more in - depth look at his complex character.
Snape's character changes in his relationship with others too. He becomes more involved with the Hogwarts community as he is now responsible for Harry. He might start to collaborate more with other teachers, like McGonagall, who he previously had a rather cold relationship with. His attitude towards the students also changes as he realizes that they are just kids trying to find their way, much like Harry. This is a big shift from his usual strict and often unforgiving self.
A lot of fanfic writers will create unique storylines for Snape's courtship. They might introduce an original character who manages to break through Snape's tough exterior. His courtship would then involve him struggling with his own insecurities and his reputation. This character might see the good in him that others overlook. There could be moments of tension and misunderstanding, but also deep, meaningful conversations as they get to know each other better.
Often in fanfiction, the ring can be a plot device. It could be that Harry Potter unknowingly has a connection to the ring, and Severus Snape has to keep it from falling into the wrong hands. This creates a situation where Snape has to protect both Harry and the ring, leading to some tense and interesting storylines.
In some fanfictions, Snape might share some of his knowledge about the wizarding world's secrets with Harry. Maybe he tells Harry about certain spells or magical artifacts that could help Harry in his fight against Voldemort. This act of sharing knowledge is a way of being nice as it gives Harry an advantage in his battles.
There are many fanfictions that explore Severus Snape's father. Some might depict him as a cruel man who had a negative impact on Snape's childhood. In some fanfictions, he could be an absent figure, which might have contributed to Snape's rather solitary and often bitter nature.
Many fanfics delve into the concept of a grudging respect growing between them. Given Snape's past with Harry's mother, Lily, there could be a connection. Snape might see more of Lily in Harry, which leads to a different dynamic. He could start to protect Harry not just because of his obligation to Dumbledore, but also because of his own feelings towards Lily. And Harry, in turn, might come to understand Snape's true nature and develop a sense of admiration for him despite their rocky start.
