Jim Moriarty was wild on a good day. He had no qualms about hurting those who crossed him. He was unpredictable and violent. But there was one thing that could cause him to turn into something worse. There was one person in the world that was important to Jim. This man held the greatest criminals heart and soul. Jim Moriarty belonged to this man and this man belonged to him. The man, who with one word could make Jim turn the world to blood and flame went by the name John Watson. And if John Watson was anything but perfectly happy and healthy Jim would do anything to fix that. And if he was injured Jim turned into a force of nature. He ripped people to pieces with his bare hands. Which is what he was doing right now. Three men who thought kidnapping John Watson would be a good idea were currently hanging from the ceiling, chains wrapped around their wrist. They were unrecognizable, missing body parts, covered in blood, bones broken, teeth missing. Jim had no mercy for those who took his treasure from him. And those who injured him deserved nothing more than the most excruciating deaths possible.

Sebastian had taken John home when they had found him. Jim had placed kiss after kiss all over Johns face before sending him away to get fixed up. John had a few bruises and a bump on the head but was otherwise unharmed. And some of the damage done to the kidnappers had been there before Jim had appeared. John was a fighter.

With the three men ripped to shreds Jim headed home. A quick stop at one of his apartments for one of the shortest showers he had ever taken and then he was walking into their bedroom where John was sitting on the bed with an ice pack on top his head. His face was a bit swollen, pale bruises forming and a few tiny cuts.

"How are you darling?" Jim asked, hovering but not touching.

"I'm fine." The words were spoken wearily but Jim knew better than to contradict John.

"Would you like to lay down?"

"Yeah, just let me put some balm on these." The walked into the bathroom, Jim a few steps behind John the whole way, a nervous bounce to his step. John settled himself in front of the mirror with the balm and Jim sat on the edge of the bathtub.

Jim watched as John expertly rubbed the balm onto his tender bruises, bandaging anything that needed it and taking an aspirin. Jim wanted to help but he also did not want to accidentally hurt John so he sat and watched. His hands twitched on the edge of the porcelain.

Once John was done Jim took his hand and lead him into their bedroom before helping John change into sweats and a tee-shirt. He changed as well before crawling into the bed next to John.

They curled protectively around each other.

"I love you." John spoke softly.

"I wish I could lock you away so you never got hurt." Jim looked very serious.

"I wish we could stay in bed forever and survive on sex." John had a smirk on his face.

"I could get on board with that." Jim responded. His face softened "I love you more than anything."

"I know." John whispered the words before drifting off into sleep.

Jim tightened his arms around John "I would burn the world before losing you."
