Another theme is discovery. Whether it's new magical elements, like strange sea creatures or hidden spells that are only accessible on the beach. The beach is often depicted as a place full of mystery in these fanfictions.
One common theme is the exploration of their relationship. The beach setting provides a more relaxed and intimate backdrop compared to Hogwarts. It allows for a deeper exploration of their friendship or the potential of a romantic relationship.
A third theme could be self - discovery. Away from the hustle and bustle of school and the war, Harry and Hermione have time to reflect on themselves. On the beach, they might realize new things about their own powers, desires, or their place in the wizarding world. For example, in some fanfictions, Hermione might discover a new aspect of her magic while feeling the energy of the ocean.
One common theme is the exploration of their relationship. Since in the original books they were just friends, fanfictions often look at how they could become more. Another theme is adventure. They might go on quests together that weren't in the original series. And of course, the theme of growing up and dealing with the challenges of the wizarding world as a couple is also quite common.
One common theme is friendship. Since they are such good friends in the original series, fanfictions often explore the deeper levels of their friendship, like loyalty and understanding.
Nature and its beauty is a significant theme as well. The sunsets, the waves, the sand - all are described in detail. It gives a sense of peace and tranquility. Also, sometimes there are themes related to family, like a family reunion on the beach or a family dealing with some issues while on a beach holiday.
The theme of friendship evolution also comes up. When Harry defends Hermione, it deepens their bond. Their relationship progresses from just being school friends to a more profound and unbreakable connection. This is often explored through how they interact after Harry has defended her, such as sharing deeper secrets or having a stronger trust in each other.
One common theme is acceptance. Hermione has to accept Harry as a werewolf and he has to accept himself. Another theme is protection. Harry often feels the need to protect Hermione from the dangers associated with his condition. For example, in many fanfics, he tries to keep her away from other werewolves or those who might use his weakness against them.
A very common theme is the power of teamwork. Harry and Hermione are both intelligent and resourceful, and in fanfiction, they often combine their skills to overcome great obstacles. Another theme is love, not necessarily romantic love, but love in the sense of caring deeply for each other. It could be platonic love that gets tested in difficult situations, like when they have to make sacrifices for each other in the face of danger.
One common theme is friendship. Their snuggling is often a way to show the closeness of their platonic relationship. Another is comfort, like when they are stressed about Voldemort or schoolwork.
One common theme is the exploration of complex relationships. Since there are two Hermiones, it often delves into how Harry's relationships with each of them differ and develop. Another theme is the idea of alternate realities or universes, as having two Hermiones can be a sign of a deviation from the normal 'Harry Potter' canon.
One common theme is adventure. They often go on adventures to discover new beasts or protect them. Another theme is friendship. Their relationship as friends is explored while they face challenges related to the beasts. And of course, mystery. There could be a mystery about a particular beast's origin or power.
One common theme is the exploration of polyamorous relationships. It shows how Harry and Hermione can be in a relationship with multiple characters and how they all interact. Another theme is often power dynamics, as some characters in the harem might have different levels of magical ability or social status.
