A plot where Hermione discovers an old spellbook that was once Severus Snape's. As she delves into it, she starts to understand his past and his motives better. This could lead to a series of events where she tries to redeem his reputation within the wizarding world, even though he's no longer alive. She could face opposition from some who still hold grudges against Snape.
One idea could be a time - travel plot where Hermione goes back in time and has to work with a younger Severus Snape. They could team up to prevent a dark wizard from rising earlier than in the original timeline. This would put them in a situation where they have to trust each other despite their differences in age and temperament.
Well, a plot could be that there is a mystery in Hogwarts that only Snape and Hermione seem to notice. They start investigating together, initially distrusting each other. As they dig deeper, they find that it is related to a long - forgotten potion recipe. Along the way, they have to face challenges like avoiding other teachers' suspicions and dealing with some magical creatures that are guarding parts of the mystery. Another interesting plot could be that Snape and Hermione are magically linked in some way, perhaps due to a spell gone wrong. They start experiencing each other's emotions and memories, which forces them to understand each other on a much deeper level. This could lead to a whole new relationship between them, different from the typical student - teacher dynamic.
One idea could be that the marriage law forces them to live together. At first, they are at odds, but as time goes on, they start to understand each other's intelligence. Snape realizes Hermione's thirst for knowledge is similar to his own. They begin to study potions together, and Snape teaches her some of his advanced techniques. Slowly, a bond forms between them that goes beyond the forced marriage.
A plot where Snape, after his supposed death, is brought back in a way and Hermione discovers him. She then has to help him regain his strength and memories. Along the way, they form an unlikely friendship and explore the secrets of magic that Snape had been researching before his death. It could involve Hermione seeing a different side of Snape than she ever expected.
A possible plot could involve Hermione inheriting Snape's potions skills in an even more profound way. She could use her combined intelligence from her mother and potions talent from Snape to create new spells or potions. Snape, as her father, would be torn between his loyalty to the Dark Lord (in some versions of the story) and protecting his daughter from the chaos of the wizarding war.
One plot idea could be Severus Snape taking in an orphaned student from Hogwarts and becoming a father figure to them. He could teach the child not only magic but also important life lessons. Another idea is a time - travel plot where an adult character goes back in time and Severus Snape ends up being like a father to them in their new timeline.
Well, we could have a fanfiction where Snape is alone after the war. He's left to pick up the pieces of his life. He decides to go on a journey to find a place where he can truly be at peace. Along the way, he meets some muggles who unknowingly teach him about the simplicity of life. This makes him realize that he doesn't need all the magical trappings to be happy.
One idea could be that Snape takes Malfoy under his wing in a more personal way than just as a student. Maybe he discovers Malfoy's hidden talents in potions that no one else has noticed and helps him develop them further. This could lead to a bond between them that goes against the typical Slytherin hierarchy.
One idea could be exploring Snape's family history as a pureblood. Maybe he discovers a long - lost family secret that has been hidden for generations. Another could be a story where Snape has to navigate the pureblood society's expectations while still being true to his own beliefs and loyalties.
Another plot idea could be that Snape's skills as a potion - maker are seen in a different light as a girl. She might be underestimated more often at first, but then she uses her skills to gain respect in a more unexpected way, like creating a potion that helps solve a mystery in Hogwarts.
One idea could be a time - travel plot. Snape goes back in time to change the events that led to Lily's death. He tries to prevent Voldemort from targeting the Potters. This would involve a lot of interaction with his younger self and trying to navigate the past without changing too much.
