Fanfiction about Severus Snape staying as headmaster: What are some interesting plot ideas?

One plot idea could be Snape having to deal with the divided loyalties among the students and staff. Some might still suspect him of being a Death Eater, while others start to see his true dedication to the school. He could introduce new potions classes with a more practical approach, like teaching students how to create antidotes for the latest dark magic threats. Another idea is that he uses his position to secretly protect students with a connection to the Order of the Phoenix, all while maintaining the appearance of strict Hogwarts discipline.

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.

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.

One idea could be that Snape's portrait has the ability to communicate with the living not just in the castle, but also with those who were once his students far away. It could offer guidance to Harry Potter's children, sharing secrets about the past and how to handle the new threats in the wizarding world.
