A/N: John might just be surprised as to who else stands by him.(written before season 3)
Six months after the fall the world was changing their minds about Sherlock. John and Lestrade were at the forefront of the movement. Three months after the fall John and Lestrade were sent three cans of yellow spray paint each. So they did what anyone would do with spray paint. They made Mycroft watch the CCTV for any cops and they spray painted three messages all across London.
I believe in Sherlock Holmes.
Richard Brook was a fake.
Moriarty was real.
Two months after that John found a box on the doorstep of Baker Street. When he opened the box he found a note that read, "We believe in Sherlock Holmes." It then went on for twenty pages of signature after signature. There were thousands, John couldn't believe his eyes. Underneath the signatures were four t-shirts one said, "I am Sherlocked," another says "I believe in Sherlock," a third said, "Get Sherlock, #moriartywasreal," the last one read, "I am fighting John Watson's war." Then at the very bottom of the box, underneath all of the shirts was a note that read, "Check what's trending on twitter." So that's what John did and what he found made him almost fall out of his chair. It was all things supporting him and Sherlock, not one thing was negative. It seemed, to John, that the whole word really did believe in Sherlock Holmes.
