Sherlock woke up in a daze. He hadn't remembered much, but he remembered being attacked, and John. He then snapped fully awake. John, the one thing that was important to him. Where was John. He didn't even realize he was strapped to a metal chair until he tried to move. When he tried to move he felt an excruciating pain at his abdomen. Then it all came back to him.
Sherlock was tidying up the flat because him and John went at it yet again about how messy Sherlock had been.
"I am just saying it would be nice to come home to a somewhat tidy flat. I am not saying it has to be meticulously clean, just not a pigs pen." Obviously John had a problem with a messy flat. Sherlock didn't mind as long as it didn't get In the way of his work. "John, if it doesn't get in the way of the cases, why should it matter. A clean flat it just as useless as a messy one."
John could tell he wasn't going to win with Sherlock. Honestly when does he ever? It would end the same, Sherlock making some insane deduction about John's love life, then John would storm out and go to the pub, drink then come home. The problem was never solved. John wanted to skip the bickering and just get to the pub part.
"You are just upset be-" Sherlock was shocked when John stopped him midsentence. Instead he just picked up his coat and went out the door as if nothing had happened. This fight ended differently. It left Sherlock with a weird feeling of guilt in his stomach. So to make amends, which never happens, Sherlock gave in and cleaned up a little. John would surely appreciate it. That alone brought a smile to Sherlock's face.
An hour or so had passed since John left and Sherlock hadn't cleaned much of the flat. He was still organizing the book and such. There was a knock on the door, he thought it was just Mrs Hudson so he yelled "Not right now Mrs. Hudson I am busy" Usually that would do it for the landlady. Sherlock was surprised when he heard the door open and shut. He quickly turned around not to see the little lady standing there, but a strange man he had never seen before.
"Johns not home right now. Goodbye." Sherlock said quickly. He needed to get this man out before John came home or else he would be in trouble. "I will just wait then. No rush."
Sherlock was getting heated. He just wanted John to be safe, and if that meant Sherlock had to be violent, so be it. He ran up to the man and shoved him against the way. "Now if you are not planning to die today, run. Far away." Sherlock said in a low growling tone. That didn't seem to scare the intruder. Sherlock grabbed the man by his jacket and swung him around to throw him against the bookcase knocking everything over. The man got up with fury and ran over to tackle Sherlock onto the table throwing everything off. Sherlock laid there moaning in pain for a second. He quickly snapped back into reality when he saw the man heading for the door. He quietly got up and lunged towards the man. Sherlock obviously wasn't quite enough. Right before his eyes, the man pulled out a knife and slashed it across Sherlock's abdomen and left Sherlock laying and the floor bleeding. Before Sherlock could do anymore, the man was gone. There was only one thing to do at this point. Get to John before the man got to him first.
Sherlock finally was brought back to his current situation when the door was slammed opened and the greeting "Mr Holmes. Lovely of you to join us"
