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 a fanfic, if Harry Potter goes to Snape in summer, Snape could be forced to interact with Harry in a different setting than Hogwarts. Snape might be caught off - guard by Harry's presence. He could be in the middle of some personal research or project. Harry might be seeking help from Snape, not because he likes him, but because he has nowhere else to turn. Snape, after some initial resistance, might actually offer some begrudging assistance.
Maybe he discovers some long - forgotten family secrets. It could be something about his parents or the history of the Potter family that has been hidden away in the manor.
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.
In a fanfic where Harry Potter goes to summer camp, it would be an interesting mix of the wizarding world and the typical summer camp activities. He would likely struggle at first with not being able to use his magic openly all the time. But he'd find ways around it. For example, he could use a levitation charm subtly to help set up tents faster. He might also meet other young witches and wizards in hiding at the camp. Together, they could explore the secrets of the camp, like an old abandoned cabin that has some magical properties. And he'd have to keep an eye out for any Death Eaters or their followers who might be lurking around, trying to cause trouble for him even outside of Hogwarts.
In the fanfiction, Snape could be in a really tough situation when Harry comes to him for help. On one hand, he has his loyalty to the Dark Lord (or at least that's what others think), and on the other, there's this boy who is the son of the woman he loved. He might end up guiding Harry in a very roundabout way, like giving him a potion ingredient that has a hidden meaning or leading him to a certain book in the library that contains the solution to Harry's problem.
Well, he might use his magic to defeat the dragons in Skyrim. Maybe he'd introduce some new spells to the mages there. It could be really interesting to see how his Hogwarts-trained skills fare against the challenges of Skyrim.
He might be amazed by the grandeur of Asgard. Its golden palaces and powerful magic could both intrigue and intimidate him. Maybe he'd meet Thor and they'd exchange stories about their different kinds of magic and heroic deeds.
In this fanfic, perhaps Harry might discover hidden secrets of Potter Manor. He could find old family heirlooms or secret rooms that were unknown to him before.
One thing that could occur in the 'Harry Potter 4th Summer Fanfic' is that Harry is being trained by some of the older students or even a teacher in secret. This training could be related to combat skills or ways to deal with dark magic. He might also be researching about the history of the Triwizard Tournament in the library at Hogwarts, which he has sneaked into. He could discover some dark secrets about the tournament's past that might put him in a better position to face the challenges ahead.
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.
In fanfic, when Harry Potter goes to Gringotts, he might discover some long - lost secrets about his family's vault. There could be hidden spells or artifacts that were left there by his parents or ancestors.
