Snape might show a softer side earlier in the story. Usually, he's so guarded, but at Christmas, he could let his defenses down a bit. Maybe he shares a memory of his own Christmas with Lily when they were children. This would give the reader a different perspective on his character.
He could be developed as more of a mentor figure during Christmas. In the normal Hogwarts setting, he's often seen as an antagonist to Harry. But in this fanfic, he could take Harry under his wing during the Christmas break. He might teach Harry some advanced potions techniques or share some wisdom about the wizarding world that he wouldn't usually disclose. This would show that there's more to Snape than just his prickly exterior.
In fanfic, their relationship can be less hostile. For example, Snape may not be as harsh with Harry in class as he was in the books. He could be more understanding of Harry's situation, especially considering Harry's role in the fight against Voldemort.
The relationship can be developed by having Snape protect Harry in unexpected ways. Maybe in a fanfic, there's a plot where some dark wizards are after Harry. Snape, secretly, uses his skills to keep Harry safe. Later, when Harry discovers this, Snape has to explain his actions. This explanation can be a turning point where they start to trust each other more. Snape can then start to offer words of comfort based on his understanding of Harry's situation. They could also start to work together on some small tasks, like researching a new potion that might help Harry in his fight against the dark side, which further cements their relationship.
Snape would have more opportunities to right his wrongs. For example, he could go back and be more honest with Lily about his feelings. His character could become less bitter as he gets a chance to change things that made him so resentful in the first place.
Some fanfics make Snape more openly vulnerable. In the original books, he's very guarded, but in fanfics, he might show his true feelings more easily. For example, he could be more open about his love for Lily to other characters.
In the fanfiction, Snape might be developed with more of a sense of humor. For example, in the original series, he is very dour, but in the fanfiction, his interactions with Harry in the context of a risky business situation could bring out a side of him that cracks jokes or uses sarcasm in a more light - hearted way. This would be a big departure from his usually serious self in the books.
In some fanfictions, Snape's relationship with Harry is shown as more of a father - son relationship. For example, in 'A Different Kind of Bond', Snape takes Harry under his wing early on, and they develop a mutual respect. This is very different from the strained relationship in the books.
Well, in these fanfictions, Snape often becomes more openly affectionate towards Harry. Instead of hiding his feelings behind a mask of coldness, he gradually lets his guard down. For example, he might start giving Harry small gifts like a special quill or a book on advanced magic that was once important to him.
In most of the official 'Harry Potter' lore, Harry is not Snape's familiar. However, in fanfic, the rules can be bent and rewritten. So it's possible in some very creative and non - canon fanfictions for this strange relationship to exist, but it goes against the general nature of their relationship in the original books.
Sure, there are fanfictions that explore this idea. This concept can lead to some really creative interpretations. It might make one re - evaluate the relationships in the original story. If Snape was Harry's father, it would completely change the power dynamics and emotional connections. For instance, Snape's loyalty to Dumbledore and his role in the fight against Voldemort could be tied to his fatherhood in new and unexpected ways. It also gives a chance to rewrite many of the key moments in the series from a fresh perspective.
Yes, in many fanfics about Harry Potter, Severus Snape is often given a familiar. It could be used to add more depth to his character. For example, if his familiar was a black cat, it could symbolize his mysterious and somewhat dark nature. Fanfic authors often use familiars as a way to explore the relationships between characters and the magical world around them. So it's not uncommon to see Severus with a familiar in these creative works.
