It could also be a really awkward experience. Snape is used to being strict and cold towards Harry at school. During the break, he might not know how to act around Harry without the school's formal structure. Harry might feel out of place too, but they could slowly build a strange sort of friendship or at least a mutual respect as they are forced to spend time together.
Maybe in the fanfic, there's a mystery that needs to be solved during the school break and Dumbledore believes that Snape and Harry together can figure it out. So he sends Harry to Snape. As they investigate, they face many challenges and through these shared experiences, their relationship evolves from one of animosity to a more positive one.
Well, in some fanfictions, Snape might start to see Harry in a different light. Maybe he begins to teach Harry some advanced potions techniques secretly during the summer. He could also grudgingly share some of his knowledge about the Dark Arts in a more controlled way, just to make sure Harry is well - equipped to face future threats.
In the fanfiction, Hermione spending time with Snape might also involve her trying to understand his past better. She could be the one person who finally gets him to open up about his relationship with Lily Potter. This could create an unexpected bond between them, as Hermione realizes that Snape is more complex and tragic than she initially thought.
Well, in a detention with Snape in a Harry Potter fanfic, Harry might be forced to clean out the Potions storeroom. Snape could use this time to lecture Harry about his lack of respect for Potions as a subject. Maybe he would also drop some hints about Harry's father, James, which could be both infuriating and enlightening for Harry.
Well, perhaps Snape would be even more surly during the summer. He might assign Harry extra potions work as a form of punishment or to keep him out of trouble. Harry, on the other hand, would probably be more rebellious in a fanfic scenario during summer, as he's away from the strictures of Hogwarts. Maybe he'd try to uncover some secrets about Snape that he suspects.
In such a fanfic, Harry might discover a new side of Snape. Maybe he'll see Snape's family traditions and learn that Snape is not just the strict professor he knew at Hogwarts. He could also form an unexpected bond with Snape's family members, and they might teach him some unique magic or knowledge that helps him in his future battles against Voldemort.
Well, one possibility is that Harry would learn a great deal about potions from Snape. Snape is a master in potions, and he could pass on his in - depth knowledge to Harry. Harry might also gain a different perspective on Snape. Instead of seeing him as the strict and often mean professor, he would start to understand Snape's complexity. This could lead to a more positive relationship between them, and Harry could become more skilled in magic that Snape specializes in.
In the fanfiction, Snape might take Harry because he discovers a connection between Harry and an ancient magic that could be dangerous if misused. So, he takes Harry to a place where he can keep an eye on him and make sure the magic is not exploited by the wrong people.
In a Harry and Snape detention fanfiction, Harry might finally have a chance to understand Snape better. He could see that Snape's strictness is not just pure malice but perhaps a result of his complex past. Snape, on the other hand, could start to see Harry not just as James Potter's son, but as an individual with his own struggles. They might end up having a conversation about magic that neither expected, leading to a newfound respect for each other.
They could start off on bad terms, with Snape being his usual strict self and Hermione being defiant. But as the detention progresses, they might find common ground. For example, Snape could notice Hermione's talent for potions and start to give her some extra knowledge or tasks related to advanced potions. This could change their relationship from one of animosity to one of a grudging teacher - student respect.
