A finger slip in a Johnlock fanfic could start with something as simple as hitting the wrong key or making an unintended gesture. This could then set off a chain reaction of misunderstandings, secrets coming to light, or new opportunities for romance and adventure between the two characters.
There is also 'The Reichenbach Fall'. This fanfic explores the darker side of their relationship. It's a bit more intense and the way it portrays John and Sherlock's bond is quite captivating. It shows how they support each other through difficult times.
Family branding in Johnlock fan fiction can be seen as the unique identity given to the relationship between John and Sherlock within the context of the fan - created stories. It might involve the use of specific symbols, settings, or plot devices that are repeatedly associated with their relationship. For instance, a particular flat they live in together could be a part of this branding. The fanfic writer may use this to make their version of Johnlock stand out among the many others, creating a sort of brand for their interpretation of the characters' relationship.
Another theme could be mystery and intrigue. Since Sherlock is associated with solving mysteries, fanfictions might incorporate a new mystery that involves John Hurt's character in some way, and John and Sherlock have to work together to solve it. This can add an exciting element to the story.
One common theme is the exploration of their repressed feelings. Both John and Sherlock are complex characters, and in fanfiction, it's often about how they come to terms with their emotions for each other before their first time.
One popular Johnlock fan fiction is 'A Study in Emerald' which combines the Sherlock Holmes world with a Lovecraftian twist. It's really engaging as it presents a different take on the characters.
Another theme is the element of surprise. Since Sherlock is often portrayed as being very logical and not in touch with his emotions, the first kiss can come as a shock to both him and John. It makes for a great moment of character development. In some fanfictions, this surprise kiss is what kicks off their relationship in a more romantic direction.

It also helps in differentiating one fanfic from another in a sea of Johnlock stories.
