A possible plot is that there's a magical competition in Hogwarts. Hermione and McGonagall end up being on the same team in an unexpected turn of events. They have to rely on each other's unique skills. Hermione's quick thinking and McGonagall's vast knowledge combine to overcome the challenges in the competition. During this time, they learn a great deal about each other and their relationship evolves in a positive way.
One idea could be a story where Hermione becomes McGonagall's apprentice in a special area of magic that's not taught in regular classes. They could go on adventures to find ancient spells and artifacts together.
One idea could be a time - travel plot where Harry goes back in time and McGonagall is much younger. They form an unexpected bond during a dangerous situation at Hogwarts that gradually turns into a deeper, more romantic relationship. But they have to keep it a secret due to the age difference and the rules of the wizarding world.
How about a story where Hermione discovers a hidden talent for transfiguration that even McGonagall is surprised by. They then work together to perfect this new form of transfiguration, but face opposition from some of the more traditional - minded professors. Or, in a post - war Hogwarts, they collaborate to reform the curriculum to include more practical and modern magic, all while dealing with the after - effects of the war on the students and the school.
One plot idea could be that Hermione discovers a magical lemon tree in the Forbidden Forest that has been enchanted by Fudge for some mysterious reason. She tries to figure out why he did it and uncovers a plot related to Hogwarts' future.
One plot idea could be that Hagrid discovers a magical lemon grove that has special properties. Hermione gets involved in researching it. They might face challenges like protecting the grove from dark wizards who want to use the lemons for evil potions. It could also involve them using the lemons' magic to help Hogwarts in some way, like curing a strange illness that has befallen some students.
A possible plot is that the house elf has a secret lemon - based recipe for a spell that can enhance one's intelligence. Hermione, always eager to learn, teams up with the elf to perfect the spell. But they face opposition from some traditional wizards who think it's improper to use such a non - traditional method.
One idea could be a story where Minerva and Severus have to team up to protect Hogwarts during a new, unexpected threat. Maybe a dark magic artifact is discovered near the school and they must use their combined knowledge and skills to keep it from falling into the wrong hands.
In some fanfictions, the plotline might involve a time - turner related incident. Maybe Hermione gets into some sort of trouble with time - traveling that only McGonagall can help her with. As a result, McGonagall adopts her to keep a closer eye on her and make sure she doesn't get into more dangerous situations. This could lead to some really interesting scenes where McGonagall teaches Hermione more advanced magic and Hermione uses her knowledge in new and creative ways under McGonagall's guidance.
One plot idea could be how she manages her pregnancy while still fulfilling her duties at Hogwarts. Maybe she has to keep it a secret at first and enlists the help of a few trusted colleagues like Dumbledore. Another could be exploring her relationship with the father, whether it's a fellow wizard or a Muggle, and how that relationship evolves during the pregnancy.
In lemon fanfiction, if McGonagall punishes Hermione, it could be due to violating school rules in a more extreme way than in the original books. For example, if Hermione gets involved in inappropriate behavior during a time when she should be studying or following Hogwarts' code of conduct.
