In Ravenclaw fanfiction, Snape might be depicted as having a different aesthetic. Instead of the typical Slytherin dark robes, he could be dressed in more muted blues or silver - grey, colors associated with Ravenclaw. His personal space, like his office or living quarters, could be filled with Ravenclaw - like symbols and items. His teaching style may also change, becoming more in line with Ravenclaw's open - minded approach to learning, encouraging students to question and explore different magical theories rather than just following the textbook.
In fanfiction, James Potter is sometimes portrayed as a more complex character than in the original books. He might be shown as having deeper regrets about his bullying of Snape. On the other hand, Severus Snape can be presented as even more of a tragic figure, with his love for Lily being explored in more detail. His bitterness towards James can also be magnified.
Sick fanfictions also often explore Snape's relationships in a different light. His relationship with other professors might become more friendly or at least more understanding. Since he's sick, they might come to his aid or show concern. This is different from the normal somewhat aloof relationships he has in the books. And his relationship with the students can also change. Some students might feel sympathy for him and start to respect him more, which changes the dynamic between them.
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.
Snape's relationships change. His interactions with Harry Potter could be completely different. Instead of the constant animosity, he might see Harry as a young boy in need of guidance, like he once was. He could become a mentor figure to Harry, which would rewrite a large part of the original story's dynamic.
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.
The portrait could be more open and less guarded. While the real Snape was often secretive and brooding, the portrait could be more forthcoming with his feelings. For example, he might openly express his pride in the students he once taught, especially those who have gone on to do great things in the wizarding world.
Snape's character might develop more positively. Without the burden of his past mistakes and betrayals haunting him, he could be more confident. He might be more open to forming friendships, especially with Dumbledore. Their relationship could start on a more equal footing, leading to a more trusting bond.
The Dark Mark on Snape in fanfiction can be a key plot device. It might be used to create tension in a story. For example, if other characters discover it, they may question his true allegiance. Writers often explore how Snape deals with the stigma associated with the mark. He could be shunned by some in the wizarding community because of it, and this can lead to interesting character development as he tries to prove himself.
Often, James is shown as either the bully he was in the books or as a more nuanced character who has grown past his school - day flaws. Fanfiction can give him a chance to redeem himself in Snape's eyes. Snape, on the other hand, is usually portrayed as the long - suffering victim of James' bullying, but also as a complex character with his own motives and secrets.
Some fanfictions might focus on his relationship with Dumbledore. They could show that in his suicidal state, Snape blames Dumbledore for using him and for the overall situation he's in. This is different from the canon where he was loyal to Dumbledore's cause, but in these stories, his loyalty might be more grudging and the stress of their relationship could be a factor in his suicidal thoughts.
