A/N—Hey anyone who cares to read my stuff, sorry I've been gone so long. I've been very busy and have missed this site—and all of you—a lot. This story takes place before the final scene of TFP, where they're all still at Sherlock's childhood home
What if, after John was safe from the well, and Eurus was safely locked away again, John had gotten cold. Sure, he had a blanket, but he was soaking wet and the night air was freezing. What if John really wanted to be inside, or to at least have another blanket, but he didn't want to be a bother, and everyone was stressed out enough as it was. What if John ignored the chill and just stayed right next to Sherlock, trying not to let his teeth chatter.
But…. Sherlock was the world's greatest detective. And John was not exactly stealthy, despite his many other fine qualities. So obviously, Sherlock noticed John's chattering teeth and blue lips, and the way his knuckles were white with the force he was exerting to wrap the blanket around his sopping wet form.
And Sherlock, who was partially delirious from lack of sleep and stress, and close to tears because of the weight of the whole situation-his sister's little game, John slowly drowning in a well-figured that though he'd lost control of the whole situation and nothing seemed to make sense just yet, he could at least make John a little less chilly.
What if Sherlock had taken off his precious coat and draped it clumsily around John's shaking shoulders? What if John had looked up at him, slight confusion in his eyes but a smile on his lips?
What if, among, John had rested his head ever so gently onto Sherlock's shoulder?
What if Sherlock froze for a minute, not knowing what to do, not wanting to disturb his friend, but what if he eventually relaxed, and noted that John was the perfect height to rest his head on Sherlock's shoulder?
What if Sherlock had tilted his head to rest on John's, and noted how well they fit together?
What if they just stood there like that, John in Sherlock's coat, their heads resting on the other's, amidst the chaos and confusion of police and ambulances, and the sadness and fear and depression they both felt.
What if they stood like that and somehow knew that everything was going to be okay?
