One possibility in a fanfiction could be that a lemon is used in a prank that ends up in the hospital wing under Poppy Pomfrey's care. The students might have enchanted the lemon to make a loud noise or to give off a strange smell, and when it backfires, Pomfrey has to deal with the chaos and the resulting minor injuries.
Well, in Harry Potter fanfiction, Poppy Pomfrey could be involved in some really interesting scenarios with a lemon. Maybe it could be part of a potion ingredient that goes wrong in a fan - created story. For example, a young wizard might accidentally add too much lemon to a healing potion under Pomfrey's supervision, leading to some comical or unexpected results.
The most interesting part might be how the author plays with the characters' personalities. Harry Potter is known for his courage and determination, and Poppy Pomfrey for her nurturing and strict healer side. In this fanfiction, their personalities could be stretched or combined in new ways. The 'lemon' aspect might be used to show a more vulnerable side of their relationship. For instance, it could be a situation where Harry is injured and Pomfrey is not just his healer but also someone he confides in on a deeper level, and this leads to a relationship that has elements of both friendship and something more, which is different from what we see in the original series.
It deviates mainly in the relationship aspect. In the original series, there's no romantic or such intense relationship between Harry and Pomfrey. But in the fanfiction, the 'lemon' element might introduce a romantic or at least a very close relationship. Also, the fanfiction might take Pomfrey out of her normal healer role more often. In the books, she's mostly just in the hospital wing, but here she could be involved in adventures with Harry.
Another idea is that there's a student who is allergic to some of the regular ingredients in Madam Pomfrey's remedies. So, she experiments with lemon as an alternative ingredient. This fanfiction could focus on the process of her trying different combinations with lemon to find the perfect substitute potion for that student. It could also show the relationship between Madam Pomfrey and the student as she tries to help them.
The plot could revolve around a prophecy that involves the third sister, Harry Potter, and Poppy Pomfrey. The third sister could be a key figure in a magical struggle that is about to unfold at Hogwarts. Poppy Pomfrey, being the experienced healer, is initially skeptical of the sister but as they face various challenges together, they start to trust each other. Harry Potter gets caught in the middle of this as he is often the center of such magical affairs at Hogwarts. Maybe the third sister has a special ability to heal the soul, which is something new even for Poppy Pomfrey, and they use this to help those affected by dark magic.
Their relationship could be one of mentorship. Poppy Pomfrey, being an experienced healer, could mentor the third sister. Since the third sister might be new to the Hogwarts environment or the world of healing magic, Poppy Pomfrey could teach her the ropes.
One idea could be a story where Poppy Pomfrey discovers she's pregnant during a time of great chaos in Hogwarts, like during a wizarding war. She has to balance her duties as the school's healer and her new situation. Maybe she gets unexpected support from the students and teachers.
She could use lemon to make a refreshing drink for students who are recovering from an illness or injury. It might help to boost their energy and make them feel better faster.
One possible fanfic could be about Madam Pomfrey's early days at Hogwarts. Maybe she had to deal with some very difficult magical maladies that no one else knew how to handle. She could have been a young and inexperienced healer then, but her determination and natural talent for healing gradually made her the respected figure she is in the series.
Well, I found a really interesting fanfiction titled 'Pomfrey's Potions'. It's about Madam Pomfrey creating new potions to deal with the unique magical ailments at Hogwarts. She teams up with some of the professors to research and develop these potions. Then there's 'The Healing Arts of Madam Pomfrey' which showcases her teaching a select group of students about the art of healing. It's a heartwarming story that shows her passing on her knowledge. Also, 'Madam Pomfrey's Memories' is a great read as it unfolds her memories from when she was a student herself and how it influenced her career as a healer.
