One common theme is identity. Since she's in Hermione's shadow, she often has to figure out who she is on her own. Another theme is family loyalty. Despite the differences, the sister usually has a strong bond with Hermione. For example, in many fics, they'll stand up for each other against bullies.
There's a fanfic titled 'Hermione's Little Sister's Adventure'. In this, the younger sister embarks on a journey to solve a mystery that has been plaguing Hogwarts. It's full of twists and turns, and she teams up with some unexpected characters from the wizarding world to get to the bottom of it.
Self - discovery is also a theme. Hermione often has to learn more about herself, her limits, and her potential in fanfiction. For instance, when she is faced with a new magical ability or a difficult moral choice, she has to look inward and figure out who she really is and what she stands for.
One common theme is her thirst for knowledge. Fanfictions often depict her going beyond the regular curriculum to explore new areas of magic. For example, she might be researching ancient spells that are long forgotten.
One common theme is the exploration of the wizarding legal system. Since Hermione is being arrested, it often delves into how the laws in the wizarding world work, and whether she's been wrongly accused or if there are deeper political machinations at play.
Another theme is self - doubt. Given Hermione's usually confident nature, when she's depressed, she starts to question everything about herself. Her intelligence, her worthiness as a friend, and her place in the wizarding world. In some fics, she might even consider leaving Hogwarts because she feels she no longer belongs.
One common theme is friendship. When Hermione is injured, it often shows how Harry and Ron (and other friends) rally around her. For example, they might drop everything to find a way to heal her or protect her from further harm. Another theme is her own strength. Even when injured, Hermione usually shows great mental fortitude, like in fanfics where she continues to study or help others despite her pain.
The theme of growing up in the wizarding world is quite common too. Younger Hermione fanfiction may explore how she copes with the rules and traditions of the wizarding world as a child. It could be about her learning about the Ministry of Magic, the different magical creatures, and how to behave in the wizarding society. There are often elements of her dealing with the expectations placed on her as a bright young witch, whether it's from her teachers or her peers' parents. And of course, there are always the magical mishaps that come with being a young witch, like accidentally turning a classroom into a menagerie of strange animals while trying out a new spell.
Another theme could be adventure. Writers might create new magical quests or challenges for the two characters to face together. They could use their different skills and personalities to solve problems, like Hermione's vast knowledge and Daphne's Slytherin cunning. This makes for exciting and engaging stories.
Well, often there's the theme of Hermione being a princess in a hidden or alternate magical realm. This allows for a whole new world of magic and politics to be explored. It could also involve her facing challenges that are unique to a princess, like court intrigue or diplomatic issues between different magical kingdoms. And then there's the theme of her princess - self being a symbol of hope for the oppressed in the wizarding world. She might lead a revolution or a movement for better treatment of house - elves or other marginalized groups, all while looking and acting like a princess.
One common theme is the struggle for identity. Since Elena is often in the spotlight in the original story, the younger sister in fanfiction may struggle to find her own place. For example, she might be overshadowed by Elena's popularity or her relationships with the supernatural guys. Another theme is family loyalty. The younger sister usually has a strong bond with Elena and will do anything to protect her family.
