The exploration of their shared past is also a big theme. Since they were at Hogwarts together, fanfictions often go back to their school days to show how their relationship could have been different. And there's the theme of the power of love and friendship in unexpected places. Despite their initial hatred, they find a connection that goes beyond what they thought possible. It shows that love and friendship can bloom even in the most unlikely situations.
A sense of belonging is another theme. Both Snape and Sirius have had rather lonely existences in different ways. In fanfiction, they often find a sense of belonging with each other. They create a space where they can be themselves, understand each other's pain, and support one another. This theme gives a deeper emotional layer to their relationship in the fan - created stories.
I really like 'A Different Kind of Rivalry'. It shows a unique take on the relationship between Snape and Sirius. Instead of just focusing on their enmity from the original series, it creates a scenario where they have to work together and gradually start to understand and care for each other. It's a refreshing read.
One common theme is redemption. Given their rocky pasts full of enmity, many fanfictions explore how they can redeem themselves in each other's eyes. For example, Sirius might realize that Severus wasn't all bad, and Severus might come to terms with the fact that Sirius had his own reasons for his actions. Another theme is friendship against all odds. They are two very different characters, but fanfictions often show how they can form a bond despite their differences. This can be really inspiring as it shows that even the most unlikely pairs can find common ground.
Love triangles are also somewhat common in Severus Snape and Sirius Black fanfiction. Sometimes it involves a love interest from the original series, like Lily Evans, and how their feelings for her, both past and present, impact their relationship with each other. It can add a whole new layer of drama and complexity to the story.
Often, there is also a theme of character growth. The experience of mpreg can be a catalyst for both Sirius and Severus to change and develop. They might become more empathetic, or they might have to learn to rely on each other in ways they never expected before. It's a way to take these well - known characters and put them in a situation that challenges and transforms them.
There are also fanfictions where they are magically bonded in some way. This bond makes them feel each other's emotions and forces them to deal with their relationship on a much deeper level. They have to learn to tolerate and eventually accept each other, which leads to a very different kind of relationship compared to what we saw in the original Harry Potter books.
One common theme is redemption. Both Snape and Sirius have complex pasts with things they need to atone for or be redeemed from. In many fanfictions, their relationship becomes a catalyst for this redemption. For example, they might see the good in each other that others don't, which helps them on their paths to becoming better.
There are fanfictions where they are forced to team up in a situation outside of Hogwarts. This could be in a post - Voldemort world where they have to deal with the remnants of the Death Eaters. In these stories, they slowly start to understand each other's motives and personalities, leading to a new - found respect and sometimes more than that. It's really interesting to see how different authors play with their characters.
One common theme is the clash of personalities. Sirius is often seen as more carefree and rebellious, while Severus, even as a female, is likely to be portrayed as more reserved and intellectual. Their relationship in these fanfictions usually starts with some sort of conflict that they have to overcome.
One common theme could be the exploration of an unlikely relationship. Since Snape and Ron have very different personalities in the original story, fanfiction might focus on how they overcome their differences. Another theme could be the power dynamic, as Snape is a teacher and Ron is a student, which can add an interesting layer to the relationship in the fanfic.
One common theme is redemption. For example, James might be shown as trying to make up for his past bullying of Snape. Another theme is the exploration of their mutual jealousy, like Snape's jealousy over James's relationship with Lily. Also, there's often the theme of friendship that could have been, where they gradually learn to understand and care for each other.
