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.
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 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.
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.
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.
At first, Harry is likely to be angry. He might feel that Snape is being unfair and targeting him. Harry has a strong sense of justice, and when he believes he's being wrongly punished, he'll be resentful.
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.
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.
Harry could react with anger. He is a strong - willed character. So, he might confront Snape about his hatred. He would demand to know why Snape is treating him this way when they should have a father - son relationship. This could lead to a series of intense arguments between them.
Snape could be initially shocked. He's used to seeing Harry as a rather tough and rebellious student. So, seeing Harry cry might take him aback for a moment. Then he might become a bit more guarded and try to figure out if Harry is faking it or not.
