Mystery is also a big theme. Since Sherlock is a detective, the fanfictions usually involve some sort of mystery that the couple has to solve together. This not only adds to the plot but also strengthens their bond as they work through it. For instance, in some stories, they are on the hunt for a serial killer.
The theme of self - discovery is often present too. Through their relationship with Sherlock, the OC often discovers new things about themselves, like their own intelligence or courage. And Sherlock, on the other hand, may discover his more human side through his interactions with the OC.
One common theme is mystery. Since Sherlock is all about solving mysteries, the OC often gets involved in his cases. For example, in many fanfictions, the OC might have some inside knowledge or a unique way of looking at the clues that helps Sherlock solve the mystery faster.
One common theme is the bond between the OC and Sherlock. It's often about how the OC comes to care deeply for Sherlock and is willing to put themselves in danger to protect him.
The theme of power dynamics is often explored. Sherlock is a very intelligent and dominant character, and the OC may either challenge that or submit to it. This creates tension and interesting plotlines. For example, an OC who is just as intelligent as Sherlock may constantly compete with him, leading to a battle of wits that is exciting to read.
Another theme is the mystery aspect. The fanfics usually involve some sort of mystery that both Sherlock and Irene are trying to solve. It could be a case related to Irene's past or something that Sherlock stumbles upon and Irene gets involved in. For example, in some fanfics, there are secrets about Irene's family that she and Sherlock have to uncover together. This adds an element of intrigue and keeps the story going.
One common theme is the exploration of power dynamics. When a scandal occurs in the Sherlock universe with an OC involved, it often shows how power shifts between characters. For example, an OC might be in a position where they have some power over Sherlock or Watson due to the knowledge of the scandal. Another theme is redemption. The OC might be a character who has made mistakes and is involved in the scandal, but then tries to make amends throughout the fanfic.
One common theme is change. Fall is a season of change, and often in these fanfics, the OC goes through some sort of transformation, just like the changing leaves. For example, they might change their view on Sherlock or their own detective skills.
One common theme is the clash between Sherlock's rational thinking and the irrationality of the vampire world. For example, he has to use his detective skills to figure out vampire - related crimes while dealing with the fact that vampires break many of the natural laws he believes in.
A common theme is family. Since they are siblings, a lot of fanfictions explore their family dynamic, how they support or clash with each other. Another is mystery - solving, as both are known for their detective skills. They often team up or compete in solving cases in fanfictions.
A third theme is redemption. Sometimes Sherlock may have made a mistake that led to his being hurt, and the fanfiction will explore how he tries to make up for it or redeem himself. This could be related to a case he mishandled or a relationship he damaged. It gives a deeper look into his character growth and development.
One common theme is isolation. Since Sherlock is often seen as a loner, his depression can intensify this feeling. He may push people away, like John Watson, who are trying to help him. Another theme is self - loathing. Sherlock might feel that his mind, which is usually his greatest asset, is now his enemy. He may struggle with feeling inadequate despite his intelligence.
