One good 'Hermione Catches Harry and Ginny' fanfiction could be 'The Unexpected Encounter'. In it, Hermione stumbles upon Harry and Ginny sharing a private moment in the Hogwarts gardens. It beautifully captures the shock and confusion on Hermione's face. Another might be 'Caught in the Act', which delves deeper into Hermione's feelings of betrayal and how it affects their friendship triangle.
In many fanfictions, when Hermione catches Harry and Ginny, it often creates a rift in their friendship. For example, in some stories, Hermione may feel left out or betrayed, which then drives her to distance herself from them. This can lead to a whole new set of plot developments, like Hermione finding new friends or getting involved in different magical adventures on her own.
Yes, there are likely fanfictions with such a plot. Fanfiction writers often explore alternative relationship dynamics in the Harry Potter universe. However, this goes against the canon where Harry ends up with Ginny.
He could also be secretly amused. Despite his stern exterior, Snape might see a bit of his own unrequited love in their relationship. So, he might give them a stern warning but not be as severe as he usually is.
Maybe Snape catches them in the middle of a magical experiment gone wrong. Harry and Ginny were trying to recreate an old spell they found in a dusty book, and the resulting chaos draws Snape's attention. He then has to decide whether to punish them or help them fix the mess.
This is a very controversial and uncanonical concept for the 'Harry Potter' series. While there might be some fanfiction out there exploring such dark and untrue-to - the - original - story ideas, it goes against the essence of the relationships J.K. Rowling created. I personally don't support such fanfictions as they distort the well - loved characters and their relationships.
One common theme is the theme of mentorship. Sirius often takes on a mentorship role when he catches them. He uses his knowledge of the wizarding world, especially the darker aspects, to guide Harry and Hermione. Another theme is friendship. Their friendship is tested and strengthened when Sirius catches them in some kind of 'forbidden' activity. It shows how they support each other through difficult situations.
In Ginny and Hermione fanfiction, Ginny is often portrayed as bold and adventurous. She's not afraid to take risks and is very confident in her magical abilities. Hermione, on the other hand, is the brains of the duo. She's highly intelligent, studious, and always has a plan. Their combined characteristics make for an interesting dynamic. For example, in many fics, Ginny's impulsiveness might get them into a tricky situation which Hermione then uses her wits to get them out of.
One great fanfiction could be where Harry, Hermione, and Ginny go on a secret mission together. Maybe they discover a hidden chamber in Hogwarts that was unknown even to Dumbledore. They have to use their combined skills - Harry's courage and Quidditch skills, Hermione's vast knowledge, and Ginny's powerful magic - to solve the mystery within the chamber.
One possibility is that Harry would be extremely hurt and angry. He might immediately confront Ginny about it. He could cut off all ties with her and distance himself from their mutual friends as well, feeling betrayed not only by Ginny but also by the false image he had of their relationship.
