One possibility is that a potions accident could cause a time - related mishap. Maybe the potion was supposed to be a simple Sleeping Draught but due to the accident, it creates a time - loop. The characters find themselves repeating the same day over and over until they figure out how to reverse the effects of the botched potion. This could be a really interesting plot device in a Harry Potter fanfic as it would allow for a lot of character development and exploration of different choices within the same day.
One idea could be that during a potions class, Harry accidentally mixes the wrong ingredients and creates a potion that makes everyone's voices switch bodies. So Hermione might sound like Ron and vice versa. It would lead to a lot of comical situations as they try to reverse the effect.
One possible scenario in such a fanfiction could be that during a potions class, Harry and Draco are forced to be partners. They are making a complex potion, and due to their mutual dislike and lack of proper communication, they mess up the ingredients. The potion explodes, covering them both in a strange goo. This accident could be the start of them seeing each other in a different light, perhaps realizing that they are not so different when it comes to making mistakes.
Neville could be a great main character for this kind of fanfiction. He's not as confident in potions as some others. So, an accident where he creates a potion that makes all the plants in the Hogwarts greenhouses go wild and start to overgrow and take over parts of the castle would be an interesting story. He would then have to use his knowledge of Herbology to try and control the situation.
A great plot point could be that the potions accident results in them being able to read each other's minds. They suddenly have access to each other's deepest thoughts and secrets. This makes them extremely uncomfortable at first, but as they start to understand each other better, they form an unlikely bond. For example, Harry discovers that Draco is under a lot of pressure from his family, and Draco realizes that Harry has his own insecurities despite being the 'Chosen One'.
Sure. There's a fanfiction where the main character is a potions genius who uses their skills to help Harry and his friends in unexpected ways. This character might be able to brew potions faster or create more powerful versions of existing potions. It adds an interesting twist to the familiar Harry Potter world and makes for an exciting read.
One way sexual tension shows up in such fanfiction is through the power dynamics in the potions setting. A powerful wizard or witch might use their knowledge of potions to gain an upper hand in a relationship, creating a push - pull dynamic. In a story where Snape is a central figure, his brooding presence and his expertise in potions could lead to a charged atmosphere when he interacts with a student or another character. This can be both intimidating and alluring, adding to the sexual tension.
In some fanfictions, Harry Potter might be portrayed as a potions prodigy due to hidden talents that were not fully explored in the original books. Maybe he has a natural affinity for the ingredients, or he has an intuitive understanding of the brewing process.
Hermione is often a common character. She might be helping Harry with research related to the potions professor's strange behavior or new potions they are working on. For example, she could be scouring the library for information about a rare ingredient the professor has introduced.
Maybe he's being bullied by Snape. Snape has always been tough on Harry in potions class. His harsh words and unfair treatment could easily make Harry feel frustrated and cry.
