Well, it usually starts with animosity. Harry has long - held negative feelings towards Snape, and Snape isn't exactly fond of Harry either. But as Snape begins to mentor Harry, things change. Snape starts to see potential in Harry and decides to cultivate it. He may start by teaching Harry about the history of magic, which piques Harry's interest. Harry, in response, starts to respect Snape's intelligence. As time goes on, they might even develop a sort of father - son relationship, with Snape guiding Harry through the difficult world of wizardry, and Harry looking up to Snape as a mentor and a source of wisdom.
In many fanfics, their relationship development is a complex journey. Snape might be forced to mentor Harry due to some magical obligation. Initially, there's a lot of tension. Harry resents Snape's harshness, and Snape is impatient with Harry's inexperience. However, as they spend more time together, they begin to understand each other better. Snape might share his past with Harry, which makes Harry more sympathetic towards him. They might also have common goals, like protecting Hogwarts, which brings them closer together.
At first, it's often rocky. Harry is used to seeing Snape as an enemy, so he's very distrustful. Snape, on the other hand, has his own grudges against Harry's father. But as the mentoring progresses, Harry starts to see Snape's knowledge and skills. For example, Snape might teach Harry a difficult potions technique, and Harry realizes Snape is a great teacher. Snape, in turn, may start to see Harry as more than just James Potter's son, and their relationship slowly improves.
At first, their relationship is likely to be very tense. Harry is used to seeing Snape as an enemy. But as Snape starts to mentor him, Harry begins to see Snape's knowledge and skills. Snape, on the other hand, might start to see Harry as more than just James Potter's son. As time goes on, they develop a mutual respect. Harry respects Snape's magical abilities and Snape respects Harry's determination. Eventually, they could become something like a reluctant teacher - student duo that also has elements of a father - son relationship, especially considering Snape's love for Harry's mother.
Their relationship develops in a rather interesting way. Snape, being a strict mentor, forces Harry and Draco to look past their differences. Harry begins to understand Snape's past and the reasons for his actions, which in turn makes him more open to Draco. Draco, who has always been in Snape's good graces to some extent, has to adjust to sharing Snape's attention with Harry. This causes some initial jealousy but later leads to a sort of rivalry - turned - friendship as they both grow under Snape's tutelage.
At first, Harry might be very suspicious of Snape's kindness. After all, in the original story, they had a rather tense relationship. But as Snape continues to be kind, Harry starts to see him in a new light. He begins to trust Snape more and more.
The relationship would be a rocky one. Snape has his past grudges against Harry's father. However, living together, they would be forced to interact daily. Harry might start to understand Snape's difficult past and Snape could see Harry's potential. There could be moments of anger, but also moments of mutual understanding, like when Harry helps Snape with some magical experiment.
In some fanfics, at first it gets worse. Harry might start to fear or hate Snape even more after being hurt. But as the story progresses, there could be a turning point. Maybe Harry discovers Snape's real motives behind the hurt, like if Snape was trying to protect him from a greater danger in a very roundabout way. This could lead to a begrudging respect or even an odd sort of friendship in the end.
One great example could be 'A Different Sort of Guidance'. In this fanfic, Snape takes Harry under his wing in a more private and reluctant way. He starts to teach Harry about advanced potions and also imparts some of his knowledge about the Dark Arts, not to encourage Harry to use them, but to understand the enemy better. Another is 'Snape's Unlikely Apprentice', where Snape is forced to mentor Harry due to a magical decree, and their relationship develops from one of mutual dislike to grudging respect.
The development could also be due to the way the author writes Snape's backstory in the fanfic. If the author delves deeper into Snape's past, his difficult childhood, and his love for Harry's mother, Harry might start to understand Snape better. This understanding leads to admiration as Harry realizes that Snape is not just the strict and seemingly cruel professor he thought he was.
It could also develop through shared experiences. For instance, if they are trapped in a dangerous place with various magical traps. They have to help each other out, like when Harry is about to be hit by a spell from a trap and Snape jumps in to protect him. This act of self - lessness can start to change their relationship for the better.
At first, it would be really rocky. Harry would be suspicious of Snape and Snape would be his usual grumpy self. But over time, as they get to know each other better, they might start to respect each other. Harry could learn about Snape's past and his complex relationship with his mother, which might soften his view of Snape.
Well, in some fanfictions, their relationship becomes almost like a father - son bond. Snape, having lost Lily, starts to see Harry as someone he can protect and guide. Harry, on the other hand, who has always lacked a proper father figure, starts to look up to Snape. This change is really heartwarming in stories where it's well - written. They start to trust each other more, share secrets, and work towards common goals, like fighting against the dark forces in the wizarding world.
