Sherlock was sitting on his small couch with a face of no expression. The sun shining through the dark clouds of the London sky. The sound of traffic that drowned out your thoughts. He wasn't daydreaming, but he was still. Very still and he looked like he was in a trance of some kind. John slowly walked into the apartment and Sherlock couldn't have paid less attention.
"You alright Sherlock? You look a bit off."
Sherlock had no response. He just carried on sitting there in this trance. John became saddened by the absence of Sherlock. He was there physically, but mentally, he was in his own world. John kept trying to talk to Sherlock to try and get some kind of response.
"Sherlock talk to me. Sherlock?"
John went to get Mrs Hudson to help him take Sherlock to hospital. John ran down the stairs rapidly, worried for Sherlock's safety. He made it downstairs but Mrs Hudson wasn't there. John thought she was out. John became more and more scared because he couldn't get help now.
He suddenly heard a small sound slowly getting louder from upstairs. John crept up the stairs very slowly and peeked into the room. Sherlock had gotten up and was playing the violin. John was very confused as to what was going on. He began to start to question Sherlock. But Sherlock doesn't talk when he's playing the violin. So John had to think of a reasonable explanation for what Sherlock had done.
A few days had passed and Sherlock was speaking again. He had just woken up and was in the kitchen performing some kind of experiment. John got out of bed and went to the bathroom as he would. But when he went to the door to go and find the reason for this whole thing with Sherlock, he noticed something. A marking. There was a small marking in the door. It looked peculiar but familiar to John. It looked somewhat simple. Just a few scratches near the bottom right corner of the door. John thought Mrs Hudson may have left it behind but why would she have been leaving scratches? Was she drunk? Was it Sherlock? John dismissed it for the time being but kept the thought of it in the back of his mind.
Sherlock finally spoke to John.
"Morning John, how would you like your tea?"
"Sherlock. You know I drink coffee in the morning."
"Ah yes simple mistake. Sorry John. You seem kind of angry?"
"Yes of course I'm bloody angry Sherlock! Can you give me some sort of reason of why you were just lying still on the couch?"
"What? When did this happen John? Are you sure you weren't having a bad dream again?"
"No. I remember it. And Mrs Hudson wasn't in and I didn't know what to do and the next thing I know you were playing the violin. Tell me what happened Sherlock!"
"I remember playing the violin yes. But the scene you're describing never happened"
Sherlock seemed to not remember being on the couch. John was very confused. He didn't know what to do so he stormed out and went downstairs to 'Speedy's Café'. John was thinking about what had happened when he remembered the marking. John thought maybe it was Sherlock, and maybe it had happened during his blackout. These were all guesses so he didn't make any assumptions. He just sat there. Wondering.
