Another theme could be the impact on his relationships. If he drinks human blood, it could put a strain on his relationship with Bella or his vampire family. For example, they might see him as a threat or be disappointed in him for giving in to his baser instincts.
The theme of redemption can also be present. After drinking human blood, Edward could embark on a journey to make amends. He might try to find a way to reverse the effects or atone for his actions by protecting humans from other vampires or doing some great good in the world to make up for his lapse.
In some fanfictions, Edward's drinking of human blood could be a part of a darker, alternate universe. Maybe he's been turned into a more feral vampire and has to relearn how to control himself with the help of other characters.
In these fanfictions, a prevalent theme is the power of love. Their act of making love is a manifestation of the strong love that has been building between them. Another theme is the discovery of sensuality in a human context. Since they are in a human - like situation in the fanfictions, they explore their sensuality in a new way. Additionally, the theme of commitment often runs through these stories. Making love is seen as a step towards a deeper commitment in their relationship, not just a physical act but a sign of their long - term devotion to each other.
One common theme is the exploration of human emotions. Since Edward is usually a vampire in the original, when he's human in fanfiction, there's a lot more focus on his basic human feelings like fear, vulnerability, and simple joys. For example, he might experience the fear of getting sick or the joy of a first love without the vampire - related complications.
Another theme is self - discovery. As a human, Edward has to figure out who he is without the allure and power of being a vampire. He might question his own values, his place in the world, and what he really wants to do with his life. This often leads to a journey of self - exploration and growth in the fanfiction stories.
One common theme is the exploration of different types of love. There's often a mix of romantic love, friendship - like love, and loyalty among the characters in the harem. Another theme is the growth of Edward as a character as he deals with multiple relationships.
One common theme is the exploration of new powers. Since they are witches, they get to discover and master different magical abilities.
One common theme is the exploration of a forbidden or unexpected love. Since they were previously seen as family within the Cullen coven, their new relationship as mates goes against the normal perception. Another theme is the discovery of self - identity. As they become mates, they might question who they are within the family and the vampire world anew. For example, Esme might wonder how her role as Carlisle's wife was different from her new role as Edward's mate.
One common theme is love and loss. Since Edward has such strong feelings for Bella in the original story, many fanfictions use his crying as a reaction to the potential or actual loss of her. Another theme could be his struggle with his vampire identity. His crying might be a sign of his dissatisfaction or pain with what he is.
One common theme is the exploration of power dynamics. Since Bella is a vampire and Edward is human, it changes the traditional power balance in their relationship. For example, Bella may have to protect Edward from other vampires.
Love against all odds is a very common theme. Since they are from different species, there are a lot of obstacles in their relationship. For example, in many fanfictions, Bella has to control her vampire instincts around Edward, which adds a layer of tension.
