Another concept might be the relationships in the fanfiction. Since the original series has unique characters, in fanfiction, their relationships can be developed in different and creative ways, like exploring a deeper friendship between characters that were only casually acquainted in the original.
Another theme is friendship and relationships. As the story progresses, the characters' relationships develop.
