A really interesting plot could be that Snape and Lilly find a way to reverse the effects of dark magic on some of the Death Eaters who were once their classmates. They use their friendship and their unique understanding of each other to break through the barriers of hatred and fear that the Dark Arts had instilled in those people. This would involve a lot of emotional turmoil as they deal with their own pasts and the pasts of those they are trying to save.
One plot idea could be that after Lilly survives Voldemort's attack, she and Snape work together to secretly undermine the Death Eaters from within. They use their knowledge of both the wizarding world and the Dark Arts to pass false information. Another could be that they start a secret organization to protect half - bloods and Muggle - borns, using their combined influence in Hogwarts and the wider wizarding community.
In many fanfictions, Severus Snape and Lilly are depicted as still friends. Some fanfictions rewrite the canon events to prevent the rift that occurred in the original story. For example, they might change the way Snape was drawn into the Death Eaters or how Lilly perceived Snape's actions. This allows them to maintain their friendship, often with added plotlines that involve them working together against the dark forces in the wizarding world. It gives readers a sense of what could have been and a chance to explore a different side of their relationship that was full of potential in the beginning.
In some fanfictions, Severus Snape and Lilly are still friends because time - travel is involved. A character might go back in time and prevent the events that led to their falling out. As a result, they remain friends and their relationship blossoms in a more positive way. Also, there are fanfictions where Lilly has a more forgiving nature. When Snape makes mistakes, she is quick to forgive and they continue to be friends. This is different from the original story where her patience seemed to wear thin over time.
Well, first of all, their friendship would probably make the staff room a more harmonious place. Professors would see that two people from such different backgrounds and houses can be friends. In the classrooms, Snape might be less harsh on Gryffindor students because of his friendship with Lilly. And Lilly could use her friendship with Snape to encourage more Slytherin students to be open - minded about Muggle - borns. This would change the overall atmosphere of Hogwarts, making it a place where friendship and acceptance are more valued than house rivalries.
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.
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 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.
