Harry would likely become more conflicted. On one hand, he has always seen Snape as a difficult figure, and now he has to accept him as his father. His view of himself and his family would change. He might start to question his Gryffindor values as he realizes he has a Slytherin father. This could lead to a more complex and nuanced character as he tries to reconcile these two different parts of his identity.
At first, Harry would be in shock. But as he gets used to the idea, he would grow in maturity. He would no longer be just the Boy Who Lived, but also a son who has to understand his father. Harry would start to study Snape's past more closely, learning about his motives and actions in a new way. This would make him more perceptive and understanding of the grey areas in people's characters. His relationship with his friends might also change slightly as he now has this big secret to keep and a new family dynamic to navigate, which would all contribute to his overall character development.
In this kind of fanfiction, one possible plot could be that through some magical accident or powerful spell, Harry discovers that Snape is actually his father. Maybe a time - traveling spell goes wrong and reveals long - hidden secrets. Harry then has to deal with the newfound relationship, and Snape has to come to terms with being a father figure he never expected to be.
Harry might become more introverted and studious. Since Snape is known for his academic prowess, Harry could inherit some of that trait. He might also be more distrustful of others at first, given Snape's own guarded nature.
In such a fanfiction, Harry would grow in his understanding of the dark side of magic. Being captured by Voldemort means being exposed to the darkest and most malevolent forms of magic. This would make him more cautious in his own use of magic, but also more knowledgeable about how to counter dark magic. His character would also become more patient. He can't rush into things as he is in a very dangerous situation. He has to bide his time, wait for the right moment to escape or fight back. This new - found patience would be a valuable asset in his future battles against Voldemort. Moreover, he would develop a stronger sense of self - identity. He would be constantly reminded of who he is and what he stands for in the face of Voldemort's attempts to break him.
Snape's character development in this fanfiction would be quite complex. At first, he might be very hesitant and unsure of how to be a father. But as he spends time with Harry, he'd gradually let down his guard. He'd find himself enjoying the simple joys of seeing Harry learn and grow. His relationship with the other Hogwarts staff might also change. He could become more collaborative as he realizes he needs support in raising Harry. His loyalty would still be there, but it would expand to include his newfound family with Harry. This would completely transform his character from the bitter and vengeful man he was in the original story into a more well - rounded and loving person.
Harry would likely become more patient. Parenting alone requires a great deal of patience, especially when dealing with a child's tantrums or questions. He would also become more self - reliant, as he can't always rely on others to help with parenting tasks.
His character might become more independent. Since he has to adapt to a different wand, he can't rely on what he already knows about using his old wand. He would need to be more experimental with his magic. This could make him bolder in trying new spells and techniques.
Snape might become more conflicted. On one hand, he has this responsibility towards Harry now that he has been taken from his father. He may start to see Harry in a different light, not just as the son of his old rival. His loyalty might be tested as he has to balance his past grudges and his new role in Harry's life.
Harry would likely become more self - reliant. Without the support of his parents, he'd have to learn to take care of himself. He might grow more cautious and distrustful, especially if he doesn't know the real reason for the disownment.
At first, it would be really rocky. Harry has a history of distrusting Snape, and Hermione might be a bit cautious too. But as time passes, Snape's care for them in his own strict way would start to show. He'd probably be tough on them about their studies, but they'd see it's because he wants them to succeed.
At first, it would probably be very rocky. Snape has long - held grudges against Harry, and Harry doesn't trust Snape much either. But as time goes on, they might find common ground. Maybe they both love a particular type of magic or have a shared goal of protecting Hogwarts from an unseen threat.
