Towards the end of the fanfiction, their relationship could become one of mutual respect and trust. They might be facing a powerful enemy together, and Snape's self - sacrifice or some heroic act finally cements Harry's trust in him completely. Harry might even consider Snape as a mentor or a friend at this point.
As the story progresses, they might start to work together more closely. Snape could be teaching Harry some advanced magic that no one else knows, and through this process, they build a bond. Harry begins to understand Snape's past better and realizes that they have more in common than he thought, like their love for Lily Potter in different ways.
In this fanfiction, their relationship could develop in a rather unexpected way. Maybe Snape initially approaches Harry for his own reasons, but as time goes on, a real bond forms. Harry, who has always been in need of someone to trust, finds in Snape a kind of stability. Snape, on the other hand, might change his attitude towards Harry completely. He might stop being so cold and distant and instead become a warm and reliable figure for Harry. This transformation in their relationship is likely to be a central part of the fanfiction's plot.
Perhaps in this fanfiction, Snape has proven himself to Harry in some extraordinary way. Maybe he has saved Harry's life multiple times or has shown his true loyalties that were hidden in the original story. It could also be that Snape has some special connection with Harry that makes Harry trust him unconditionally.
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.
Perhaps in this fanfiction, Snape shows a side of himself that is completely different from what Harry has known. He might be more open and honest with Harry, sharing secrets that make Harry believe he can be trusted. Like Snape might disclose some long - held information about Harry's parents that only he knew, which makes Harry think Snape has been on his side all along.
The relationship would start off rocky. Snape would be resistant to Harry's kindness as he has always seen Harry as James Potter's son. But Harry's persistent efforts to understand and help Snape would gradually break down Snape's walls.
At first, it's likely to be very tense. Snape has always had a grudge against Harry because of his father. But as they live together, they start to see each other's true selves. Harry might see Snape's vulnerability and intelligence, while Snape might see Harry's courage and determination that are different from James's arrogance.
Often, it starts with intense dislike. Snape is constantly critical of Harry in class, deducting points for the slightest mistakes. Harry, in turn, sees Snape as a bully. As the story progresses, there might be small moments of grudging respect, like when Harry realizes Snape's intelligence in potions, but the overall hatred remains for a long time.
At first, it could be very tense. Harry might be reluctant to submit, but as time goes on, he starts to see Snape in a different light. This could lead to a grudging respect. For example, Snape might show Harry some advanced potions techniques that no one else has taught him, which makes Harry realize Snape's value.
Initially, the relationship is one of captor and captive. Snape is in control and Harry is the unwilling victim. But as the story unfolds, Harry might begin to question Snape's motives. Snape, in turn, might start to open up a bit about his reasons for taking Harry. This could lead to a slow transformation of their relationship. They might find common ground in their shared experiences, such as both having lost people they loved to Voldemort. This newfound connection could start to heal the rift between them.
At first, the relationship might be filled with tension. Harry would be resentful of being in a slave - like position to Snape. But as time goes on, he realizes that Snape has a depth of knowledge and a hidden agenda that might not be as bad as he initially thought. Snape, on the other hand, might start to see Harry not just as a tool or a burden, but as someone with potential that he can shape in his own way.
