In many Sherlock fan fictions, Sherlock branding John could be a sign of his trust or a way to get a reaction out of him. It all depends on the author's imagination and the context they create.
The way Sherlock brands John in fan fiction can be quite diverse. It might be through sharp remarks, secret gestures, or even symbolic actions that have special meanings within that particular story.
It could be through a complex mystery-solving case where he stumbles upon it. Maybe it's a clue or a reward for cracking a difficult puzzle.
It could mean that Sherlock is sharing with John a piece of fan - made fictional work that is related to the concept of 'family brand'. Maybe it's a story within the Sherlock - John universe that has a family - centered theme and is written by a fan.
The significance could be that Sherlock is trying to communicate with John in a different way. Fan fiction often explores different aspects of characters and relationships. By giving John a family brand fan fiction, he could be hinting at a deeper connection or a new way of looking at their own relationship, like a family - like bond they might have.
The relationship dynamics between Mycroft, John, and Sherlock are crucial. It could be exploring their brotherly bond in new ways for Mycroft and Sherlock, and the unique friendship between John and Sherlock. Also, good grammar and an engaging writing style matter. If the story can make you feel the emotions of the characters, like when John is exasperated with Sherlock's antics or Mycroft's subtle manipulation, it's likely a great fan fiction.
He might be initially shocked. Sherlock is used to John being more understanding, so this outburst could catch him off - guard. But then he could go into his logical mode and start analyzing why John would say such a thing.
Sherlock would be extremely worried. He might go into a state of hyper - focus, using all his skills to find John. He would analyze every little detail, from the place where John was kidnapped to any possible witnesses.
Well, in Sherlock and Fem John fanfiction, the dynamic often changes in terms of emotional expression. A female John might be more openly emotional, which can either soften Sherlock or create more tension as he's not used to such displays. Also, the power dynamic can shift. In the original, John was often the more 'grounded' one, but a Fem John might assert herself differently, perhaps more subtly or in a more feminine way.
