This is a prompt from Alice-Rose-Teatime, called Scarf or Scarves, hope you like it!
"I've got it!" Sherlock exclaimed, making John jump. They were sitting quietly as they usually do, until Sherlock disrupted the silence. Quite recently the men had received a case from Lestrade concerning an odd murder. "Come along John!" He ran out the door putting on his scarf and coat. John grabbed his coat and ran out with him.
"Would you care to explain?" He yelled out as Sherlock hailed a cab.
"I'll explain on the way." He jumped in and John followed. He explained that the murderer would be appearing somewhere in the homeless network and they only had one chance to stop him. The plan to stop him was that John was going to cover Sherlock while he snuck up on the murderer. It wasn't the best plan but Sherlock had other more 'important' things on his mind. As soon as they arrived John went into place and Sherlock found a nice and quiet spot to view where the man was coming from.
Soon John saw him and looked around to see Sherlock already fairly close to him. Sherlock jumped out and tackled the murderer and John ran closer. Sherlock had the upper hand and it seemed that the murderer was almost done for when he slipped away from Sherlock. He ran to the nearest tunnel and John started running after him. Sherlock caught up with John and they ran even after they knew that they had lost him. They stopped running and took a few minutes to calm down.
"John.. I lost my scarf." Sherlock panted. John gave him a surprised look.
"Is that all your worried about? We just lost a criminal!"
"But John, it's my scarf."
"And?" Sherlock didn't answer and started running back, searching the floor of the tunnel for his beloved scarf. John debated whether or not he should follow and decided to go to him.
"Sherlock, I really don't see why your scarf is so important!" He said when he saw the man again. Sherlock just huffed and started to walk away.
The cab ride home was silent and when they got back to 221b Baker Street, Sherlock went straight to his room. John sat in his chair and grabbed his computer to blog. After a few minutes, Sherlock came out again and grabbed his violin. He played a few notes when he turned and asked John,
"Where is my scarf, if it's not in the tunnel?"
"How would I know?" John replied.
"I was just asking." Sherlock replied, a little out of character. John thought about the scarf and its importance to Sherlock.
"I think I know where your scarf is.." He said cautiously. Sherlock spun around and looked at him, eyes squinted. "But I need you to tell me why you need it so badly." Sherlock sighed and sat down.
"Just tell me where my scarf is." He said.
"Okay," John started. "Answer my question first."
"Please?" Sherlock gave John a sincere look. John almost told him but snapped himself out of it and shook his head. "Why do I have to tell you?!"
"Because I want to know!" Sherlock fidgeted for a bit and then slumped. He mumbled something the John couldn't really hear. "Sherlock, I have to be able to understand your reason."
"I want it.. Because it was a gift from you!" And then everything came back to John. He had bought Sherlock a brand new scarf for his birthday, after he found out how stained the old one was. John looked at Sherlock and Sherlock looked back at him. "Well? My scarf's location?"
John reached into his jumper at pulled out the scarf. Sherlock looked at him wide eyed and tried to take it back. John dodged Sherlock's hand and wrapped the scarf around the other man's neck. He pulled his head down and kissed him. Sherlock didn't try to pull away. John was surprised to find out that Sherlock was actually kissing him with more passion than himself. Sadly, they had to part for oxygen and Sherlock said to John,
"Thank you for the scarf, I care very much about it."
