It was cold, too cold to walk back to his flat. He was not able to flag down any cabs, either. The tube sounded like a good idea. When he got into the train he stood erect with his hands in his jacket pockets. His name was John Watson, a former military doctor with short blond hair, blue eyes, and had just broken up with his girlfriend.

"Iraq or Afghanistan?" A voice behind him called out.

When John turned around he saw a tall man with black hair and piercing grey eyes. With closer inspection he noticed that this man had horns, he was a demon.

"Excuse me?" John furrowed his brows, "Did someone set you up to this?"

The demon sniffed the air around John, "Don't be absurd," he sniffed John, "I can smell it in you." He stated as he started to flick his tail around.

"Oh, thank you. I suppose." The train stops, John gives a quick nod of head at the demon and exits. The demon starts to follow him out, floating in the air. John starts to walk faster, trying to see if he can get rid of him. He walks up to the door of his flat, jumbling for his keys in his pocket.

"I'm Sherlock." The demon cooed and flicked his tail into John's face, "What's your name, human?"

He started to lick John's earlobe.

"Excuse me!" John shouted and pushed the demon away with both arms, now slightly annoyed. He wiped his ear with the sleeve of his shirt, "That is not okay!" He squinted his eyes at the demon. John opened the door and tried to slam it in Sherlock's face before he could get in, but it was no use, he had already slinked his way inside. John let out a loud sigh and turned to Sherlock.

"Is there anything I can help you with?" His tone of voice sounded a bit angry.

"I'd like to stay with you, for maybe a day, or a month, possibly a year," replied the demon.
