Some fanfics explore the theme of family. Since they have a very strong bond that could be seen as a form of family in the original, in fanfics this can be expanded upon. They might face challenges as a 'family' unit, or new characters could be introduced to test and develop this family - like relationship between Ray and Emma. Additionally, there are fanfics that deal with the theme of sacrifice, where either Ray or Emma has to make difficult choices for the sake of the other or their group.
A theme that's also quite prevalent is the idea of 'what if' scenarios. For example, what if certain events in the original story had gone differently? How would that affect Ray and Emma's relationship? There are also some fanfics that focus on their growth as individuals within the context of their relationship. This could involve Ray overcoming his more cynical tendencies or Emma becoming even more of a leader, all while their bond strengthens.
One popular trope is the 'protective Ray'. Since he's a rather intelligent and often calculating character, he's often depicted as being very protective of Emma in fanfictions. Another is the 'slow - burn romance'. Given their situation in the original story, their relationship might develop slowly over time, which is a common trope in fanfiction. And of course, the 'alternate universe' trope is also seen a lot, where they might be in a different setting, like a modern - day high school or a fantasy world.
In many fanfics, themes of love and conflict are prevalent. For 'emma x ray fanfic', there could be a love story budding between them, or perhaps they face conflicts due to differences in their personalities or beliefs.

Fanfics usually take the existing characters and put them in new and interesting situations, so the themes can vary widely depending on the author's creativity.
A sense of discovery is another theme. They discover new things about each other, about the world around them, or about themselves. In some fanfictions, they might discover a hidden power within themselves or a secret about their past. This discovery then shapes their relationship and the direction of the story.
A possible fanfic could focus on a time - skip scenario. After growing up a bit, Emma and Ray find themselves in a new situation where they have to reunite to save their friends again.
