One possible analysis is that it shows a different side of Sherlock. Usually, he is portrayed as very logical and detached, but in this fanfiction, falling in love with Molly allows for a more emotional and vulnerable Sherlock to emerge. It might explore how his brilliant mind copes with new, strong emotions.
There's often the 'unaware John' trope. John may be oblivious to Sherlock's growing affection, thinking Sherlock is just being his overly - intense self. And a lot of these fanfictions play with the idea of Sherlock's internal struggle. He's trying to reconcile his new - found emotions with his rational mind.
One common theme is the clash between Sherlock's logical mind and the illogical nature of love. His deductive skills are often at odds with his new - found emotions. Another theme is the transformation of Sherlock's character. He has to adapt to being vulnerable and having someone else in his life. For example, in many fanfictions, he starts to care about someone else's feelings more than just the facts of a case.
Well, when writing a 'Sherlock falls in love with Sherlock fanfic', you can begin by creating a unique setting. It could be an alternate universe where the rules are a bit different. Then, work on the dialogue. Sherlock's dialogue is always sharp and witty. When he's in love, his words might still have that edge but also carry a new layer of vulnerability. Also, consider how the other characters in the Sherlock universe would react to this relationship. Their reactions can add more depth and conflict to the story.
One popular one might be 'The Unlikely Bond'. It explores how Sherlock's analytical mind grapples with his new - found feelings for another version of himself in a very unique way. The story delves deep into their shared experiences and how those shape their relationship. It's filled with great character development and some really thought - provoking moments.
Another good one is 'Love in the Shadows of Baker Street'. It has a unique take on how Sherlock's feelings develop for John. It also has some really interesting side characters that add depth to the story.
Well, there's a fanfiction titled 'Sherlock's Unlikely Romance'. In this story, Sherlock meets a woman who challenges him intellectually and gradually he finds himself falling for her. It's interesting because it shows a different side of Sherlock that we don't often see in the original stories. Also, 'The Love Affair of Sherlock Holmes' is quite good. It delves deep into how Sherlock would handle the complex emotions of falling in love within the context of Victorian London society.
Another plot twist could be that Molly has her own secrets. Maybe she has a past or a connection that Sherlock is unaware of, and when it's revealed, it either threatens their relationship or actually deepens their bond as they work through the issues together.
Well, it allows fans to explore different aspects of Sherlock's character. For example, his relationships in ways that the original series might not have fully explored.
Obviously, Sherlock Holmes himself is a central character. His complex personality makes it interesting to see him in a romantic context. He's often portrayed as initially cold and distant but gradually warming up to love.
