In fanfiction, if Snape stays at the Dursleys, it could have a huge impact on Harry. Snape could start to teach Harry some basic magic skills early on. This would not only give Harry an advantage when he finally goes to Hogwarts but also change the way he views Snape. Harry might see Snape as a mentor figure rather than just a strict teacher. Additionally, Snape could share stories about Harry's mother, Lily, which would strengthen Harry's connection to his family heritage. Snape's presence could also prevent the Dursleys from starving or mistreating Harry as much as they do in the original story, leading to a healthier and more confident Harry.
Snape would likely be disdainful towards the Dursleys. He has little patience for Muggles in general, and the Dursleys' mean - spiritedness would not endear them to him. He might use his cold, sarcastic tone on them, leaving them confused and a bit frightened.
Maybe it was an accident. Like a wrong Floo Powder destination or some kind of misfired spell that landed Draco right at the Dursleys' doorstep just as Harry was there.
It could make Harry more empathetic. Snape is a complex character, and through his rescue, Harry gets to see a different side of him. This could make Harry more understanding of others' hidden motives and pain. He might start to look beyond the surface when dealing with people, which would be a great development for his character as he faces more complex relationships in the wizarding world.
The Dursleys would probably be more frightened. They are muggles and Snape is a powerful wizard. The idea of a strange man in black robes suddenly appearing and using magic would be terrifying for them.
Snape's teaching style would have a profound impact on Harry. Given that Snape is a master of his craft, he would not tolerate any sloppiness from Harry. Harry would have to be more meticulous and detail - oriented. This would be a change from his usual somewhat haphazard approach. Snape might also use his own experiences to teach Harry about the importance of self - control. Since Snape has dealt with his own inner demons, he could guide Harry in managing his temper and using his emotions to fuel his magic in a more positive way. Also, Snape's knowledge of the darker aspects of magic would give Harry a more comprehensive understanding of the magical world, which could be crucial in his future battles against dark forces.
Well, in fanfiction, if Snape raises Harry at Hogwarts, it would surely have an impact on his friendships. Ron, for example, might feel a bit left out at first. He was used to being Harry's closest friend, but with Snape taking on a more parental role, Harry might be spending more time with Snape, studying or learning things that Ron doesn't understand. Hermione, on the other hand, might be more understanding. She might encourage Harry to make the most of this situation. And some of Harry's other friends might be intimidated by Snape's presence in Harry's life. But overall, Harry's true friends would still be there for him, although the dynamics would be different.
Perhaps Snape uses magic to create a distraction at the Dursleys' place. He could make strange noises or apparitions that scare the Dursleys, and while they are in a panic, he grabs Harry and disapparates. This would be a quick and efficient way for him to rescue Harry.
The abuse by the Dursleys in these fanfictions is a major factor in Harry's character development. It initially makes him angry and withdrawn. However, as he grows, this anger becomes a fuel for his courage. He becomes more empathetic towards others who have suffered because of his own experiences. Also, his time with the Dursleys makes him value the friendships he forms at Hogwarts even more, as they are a contrast to the loveless environment at the Dursleys'. Overall, the abuse shapes him into a complex and strong - willed character.
At first, Harry might be extremely suspicious. Snape has always been cold and mean to him in the past. He would wonder what Snape's true motives are. Harry is used to being on his own and not relying on Snape for help, so this sudden rescue would be very unexpected.
Harry might become more reserved and cautious at first. Growing up with Snape, who is not as openly affectionate as others, would make him more self - reliant. He'd also likely become more skilled in magic quicker, as Snape is a very talented wizard.
