A very popular trope is the 'romantic triangle' between Hermione, Fabian and Gideon. However, it's not always a traditional love triangle. Sometimes it's more about deep friendships and unspoken feelings. Also, the 'mentorship' trope can be seen, where either Fabian or Gideon, or both, become mentors to Hermione in some aspect of magic or wizarding life that she's not familiar with.
One common trope is the 'time - travel' one. As in, Hermione travels back in time and gets involved with Fabian and Gideon. It allows for a lot of interesting interactions and plot developments. Another is the 'hidden connection' trope, like Hermione having some sort of ancestral or magical link to the Prewett family.
The 'mystery - solving' trope is also quite popular. For example, Hermione teams up with Fabian and Gideon to solve a mystery that has been plaguing the wizarding world for ages. This trope often involves a lot of research, clue - following, and suspense. There's also the 'unlikely alliance' trope, where they come together despite their different backgrounds and time periods.
One great Hermione, Fabian and Gideon fanfiction is 'The Forgotten Prewetts'. It delves into a time - travel plot where Hermione goes back in time and meets the Prewett brothers. The story is well - written, with great character development for all three. Another one could be 'Prewett Protectors' which focuses on how they team up to protect Hogwarts from a new dark threat.
One idea could be a story where Hermione discovers she has a connection to Fabian and Gideon through some long - lost family magic. Maybe she starts having strange dreams that lead her to uncover secrets about her heritage related to them.
One popular plot theme is time - travel. For example, Hermione might go back in time and interact with Fabian and Gideon during their Hogwarts days. This allows for a lot of interesting character interactions and the exploration of different eras in the Harry Potter world.
She could inherit some unique magical abilities from them. For example, if they had a special gift for divination, Hermione might start having more accurate premonitions. This would add a new dimension to her character and her adventures at Hogwarts.
Well, social media groups dedicated to the Harry Potter fandom can be a great source. For example, on Facebook or Reddit, there are groups where fans share and recommend their favorite fanfics. Just post a request asking for Hermione, Fabian, and Gideon fanfics, and you're likely to get some good suggestions. Additionally, Tumblr sometimes has fanfic writers who post their works directly or link to them.
The 'time - travel' trope is also common. As I mentioned before, it can be really interesting to see them go back in time and interact with the younger versions of themselves or other characters. It often leads to a lot of plot twists and revelations.
One common trope is the 'Forced Proximity'. This is where Hermione and Bellatrix are put in a situation where they have to be close to each other, like when Hermione is captured by Bellatrix. It creates a lot of tension and interesting dynamics between the two characters.
The 'power - sharing' trope is also common. This could be where Hermione's magic and the powers of the vampires or other supernatural beings in The Vampire Diaries interact in unexpected ways. Maybe she uses her magic to enhance their powers or vice versa. It creates a lot of interesting plot possibilities.
One popular trope is the 'enemies - to - lovers' scenario. They start off hating each other because of their house differences and different beliefs, but as time goes on, they slowly fall in love. Another is the 'forced proximity' trope. For instance, they might be locked in a room together for some magical reason, and during that time, they get to know each other better and feelings start to develop.
One common trope is the 'fish - out - of - water' situation. Hermione, coming from a modern magical world, is out of place in the Marauder's era. For example, in many fanfics, she is shocked by the old - fashioned views on things like house - elf rights. Another popular trope is 'changing the past'. She often tries to prevent bad things from happening, like the death of the Marauders. And then there's the 'romantic subplot' trope. There are often romances between Hermione and one of the Marauders, usually Sirius or Remus.
