It could be due to his loyalty to a certain cause or group. If there are conflicting loyalties in the fanfiction, Snape may feel that accepting Harry as his son would go against his other obligations. Or perhaps he is simply not ready to take on the role of a father, given his own complex and often troubled life.
Snape could be afraid of getting too close to Harry. He might have seen so much pain and loss in his life that he doesn't want to open himself up to the vulnerability of having a son - like relationship. His own insecurities and fears could be driving this rejection.
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 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 past experiences. Maybe he had a difficult childhood himself and doesn't know how to handle having a son. He might project his own insecurities and traumas onto Harry. Another reason could be that he sees too much of Harry's father in him. Since Snape had a long - standing feud with Harry's father, seeing those traits in Harry could trigger his hatred.
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 reason could be to add a shock factor. It completely changes the expected family relations in the original story. Another reason might be to explore Snape's character more deeply. If Harry is his son, it gives a new perspective on Snape's actions and emotions towards Harry throughout the series.
One possible reason could be their long - standing rivalry. Draco has been taught to dislike Harry from a young age due to their family differences. His pure - blood supremacist upbringing might make him reject Harry as a mate because Harry is seen as a 'Mudblood - lover' in the eyes of Draco's family and their circle. Another reason could be fear. Draco might be afraid of what the wizarding society would think if he accepted Harry as his mate. The wizarding world has its own set of norms and expectations, and a relationship between them would be highly unconventional and likely face a lot of opposition.
One possible reason could be to protect Harry. Snape might believe that by tying Harry to the bed, he can keep him in a safe place away from immediate danger. Maybe there's a threat in Hogwarts or outside, and Snape thinks this extreme measure is necessary to ensure Harry's safety.
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.
One possible reason could be his lingering resentment towards James Potter, Harry's father. Snape and James had a long - standing feud during their school days. Since Harry looks a lot like James, Snape might be transferring his old grudges onto Harry.
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.
