Paper crane
Chapter 1:
„I will burn the heart out of you!" Moriarty´s words burn with flaming hot intensity through his system. Sherlock can´t remember anymore how many days, weeks and months he is already with the mad man together, maybe already years. He hadn't a choice he wouldn't run. He will never run away even with the doors unlocked and no chain holding him back. He knows exactly where he is but he would stay and be the psychopaths …pet. He didn't have a better name for it. He was Moriarty´s play thing, his to tame pet.
Sherlock followed him willingly as far you can call it this with your best friend at gunpoint with the promise to make it hurt if not to follow him. He did, he let go of his own gun and with a last look down where John was sitting on the pool´s floor he follows Moriarty into a world full of pain and suffering. It was not only physical pain because he had found a way to make do Sherlock what he want using John as pressure point. And it works.
The first time he refused one of the things Moriarty tells him to do, he get a life-stream of Baker Street out of the view of a sniper. The sniper was aiming at John. With the promise to make it last very long. And that is how it works since the beginning. Whenever Sherlock starts to rebel or not to jump at word he gets a new picture of John with a threat to hurt him.
When Moriarty asks him to walk on his hands and knees to play dog, he would do it.
When he asks him to get naked and lay in to snow for hours he would do it.
If the psychopath ask him to eat poison food and let him suffer for days he would do it and when ask if he want some more he would say 'yes' without hesitation.
If he was told to be quiet while Moriarty sliced his initials in his skin he would stop screaming and bit his lips until the blood flows down his face.
If his keeper asks him to stop breathing he would stop to do it until he lost conscious and after waking up to repeat until Moriarty would tell him to stop.
Sherlock didn't fight the man who hurt him, he bear the pain the same as the days he was locked away taken all his senses becoming slowly insane.
The days without food and water were the easiest one but Moriarty let him do it for far longer as his body is used to it through the cases.
Once John was with Mycroft and Sherlock thought he would be save with his brother but all the fighting was useless, the monster just start to show him pictures of Lestrade and Mrs. Hudson. The first one at a crime scene and the other talking with a stranger on the street who looked very much like one of Moriarty´s man.
The moments when Sherlock got a quick look at John was somehow a relief and at the same time it made it worse. He misses John, terrible and couldn't change the fact that he was used against him. He couldn't see an end of this and if he would ever get out of here he is not sure he will be able to look at John again without seeing Moriarty and feeling fear and shame and pain and hatred.
Sherlock would still do everything Moriarty would ask of him long without even waiting for a picture of John but he would get it anyway to promote the feeling that John is the one that made him feel the pain or the fear. He also did it with Mrs. Hudson and Lestrade and after a while with his brother, his parents, Molly, a few of his homeless network and sometimes with random people just for fun like he said.
To prove his point he let some of these people have 'little accidents', got even his brother in one on the road and Mrs. Hudson got the wrong 'medicine' for her hips from her dealer but someone was with her as she collapse. The hours Sherlock had to wait to see if she had survived were pure torture, the pain Moriarty´s man were afflicted to him during this time just move in the background.
But it was always John who had the best effect on Sherlock how the big shadow would say. His mind was beginning to break and Moriarty had his fun to do it very slowly and painful. He was wiping out all hope, he overwrite his feeling for the people he cared for, not that Moriarty would use everyone he had ever known but how could Sherlock go back to work with Lestrade without thinking about the things that had been done to him. How could he eat something Mrs. Hudson had cooked for him when he had to eat rotten food next to her picture and how could he ever look at John again. John meant safety once now it was a punishment to see him. Being close would be worse.
Thinking about it, it was very unlikely that he will ever get out of here. He was a prisoner on his own free will. He stays because he wants to. He could walk out of the door anytime but his friends and family would pay the price. So Sherlock stays and let Moriarty break him.
He hates Moriarty for the pain he is giving him, he hates himself for letting it happen and sometime he hates John for being the most important person in the world for him.
