One possible reason could be Snape's long - standing grudge against James Potter, Harry's father. Since Snape had a difficult past with James, he might project that onto Harry. Another reason could be that Snape is trying to protect Harry in a very strange way. He may think that by rejecting Harry, he is keeping him at a distance from the dangerous wizarding world politics and plots that Snape is often involved in.
He may also get angry. Harry has a strong sense of justice and self - worth. Snape's rejection could be seen as unfair in his eyes, especially if he has started to develop some sort of positive feelings towards Snape. So, he might lash out at Snape or even try to prove him wrong by becoming more independent and successful on his own.
Often, it develops into a more complex and strained relationship. Harry might start to resent Snape even more, while Snape might feel guilty deep down. They could end up in a cycle of mutual dislike and misunderstanding.
One possible reason could be Snape's long - held grudges and resentments. He had a complex past with Harry's father, James Potter. Snape might see too much of James in Harry and be unable to separate the two in his mind, leading to his rejection.
One common theme is the exploration of loneliness. If Snape rejects Harry, Harry may feel more isolated than ever. This can lead to stories where Harry has to rely solely on himself and his other friends, like Ron and Hermione, more than in the original series. It can also show how Snape's actions can have a big impact on Harry's emotional state.
At first, Harry would be confused. He has always seen Snape as a complex figure, and the idea of being rejected as a son would be a shock. He might start to question his own self - worth, thinking that if Snape doesn't want him, there must be something wrong with him. As time passes, he could grow bitter towards Snape, but also use this as motivation to become stronger. He might focus on his friends and the positive relationships in his life, trying to move on from Snape's rejection while still carrying the pain deep inside.
The theme of self - worth often comes up. Hermione, after being rejected, has to reevaluate her own self - worth. Is she not good enough? Does her intelligence not matter? Also, the power dynamics in Hogwarts play a role. Snape is a teacher and Hermione a student, so there are ethical and social implications to their relationship that fanfictions might explore.
One possible reason could be Snape's long - held grudges and resentments. He has a complex history with Harry's father, James Potter. Snape might see too much of James in Harry and be unable to separate the two, thus rejecting Harry despite any potential father - son connection. Another reason could be Snape's own self - loathing and his belief that he is not worthy or fit to be a father figure. He may think that he would only bring harm or a bad influence to Harry's life.
One reason could be to explore complex character dynamics. In the original 'Harry Potter' series, Snape has a very ambivalent relationship with Harry. By writing about Snape rejecting Harry in fanfic, writers can dig deeper into Snape's internal conflict. He has his own grudges and loyalties, and this rejection could be a way to show how his past and his own sense of self prevent him from fully accepting Harry.
The rejection could be a huge blow to Harry's confidence at first. He may start to doubt his abilities and his place in the wizarding world. However, it could also be a turning point. Harry could start to explore his own identity more deeply, separate from the idea of having Snape as a father figure. He might discover new aspects of his personality and magic that he hadn't before, leading to a more complex and mature character development.
