In Harry Potter Professor Vector Lemon fanfiction, a common theme is the exploration of the character of Professor Vector herself. Writers might delve into her backstory, her personality, and how it interacts with the 'lemon' elements. There could also be a theme of the intersection between the magical world and more earthly desires. Since the Harry Potter series is set in a magical world, but 'lemon' fanfiction often has a more human, carnal aspect, there is an interesting juxtaposition.
