What friends are for

by IcanhazDEATH

The Doctor has been possessed by a demon, and goes on a killing spree in London. But there is still hope for him. When Sherlock gets the case, he knows immediately that this is no ordinary string of murders. He calls in the Winchesters, and together they try to find a way to exorcise the Doctor without hurting him. Aliens aren't the same as humans, remember Dean?

1. Criss Angel? Or something worse?

1:15 a.m.

The security guard had just started working at the gallery that night.

Nobody had warned him of the creepy shadows that danced on the works of art, nobody warned him that the building was old, so the structure creaked and sighed with age. Nobody had told him much of anything, except "Grab your uniform and get to work." He didn't like the manger here, too snobby. He quickly made his way from gallery to gallery, eager to get back to the guard room so he could just watch everything on CCTV. He was walking down a hallway that connected two galleries, when he thought he heard footsteps. These were not his footsteps, these were heavier. He immediately stopped walking, but the footsteps continued. He listened closely, trying to narrow down were they were located. He silently followed the sound of the steps, until he came upon a gallery that he had been in not five minutes ago. What the hell? All the windows are locked, and the alarm wasn't triggered. How did Harry Houdini get in? He drew his gun from the holster, and turned off the safety. Cautiously, he entered the gallery, sweeping his flashlight from left to right, searching for the suspect.

But to his dismay, the room seemed empty. This was puzzling to the man. There was only one entrance, and he was standing in the middle of it. If the person left, he would have heard their footsteps if they chose the entryway, and if he had chosen the window, they alarm would have gone off. So that left only one option: the person was still there.

As the guard came to this conclusion, he heard something that confirmed his theory soundly. There was a rumbling laugh, one that echoed through the huge gallery room. He couldn't find the source, and that frightened him. The laughing abruptly stopped, and the silence that followed it was deafening. He was starting to doubt his sanity when he spotted a figure on the far wall of the gallery. He swept his flashlight in the direction of the shadow, but it moved before his flashlight reached it. He followed the shadow with his flashlight, but it seemed to be one step ahead of him. Shadow suddenly disappeared from the wall, and he was left frantically waving his flashlight around, searching for it.

He failed to see the shadow materialize from the wall into a person, and didn't notice until he heard the footsteps getting closer. He whipped around, and brought up his gun to a defensive position. He shone the flashlight into the intruder's eyes, hoping to disorient him. The light also illuminated a head of thick, brown hair swept to the side, and a bowtie at the neck. The trespasser just growled and snatched his flashlight, throwing it across the room. The light extinguished upon impact with the floor, plunging the room into gloom. The guard could only see the faint outline of him, and he made the mistake of blinking, and the outline was gone. The guard blinked again, and this time the shadow was in front of his face. He could feel hot breath on his face, and recoiled from the sudden smell of rancid meat that wafted from its mouth. The guard kept backing up until he was against the window, moonlight pooling on the floor. When the intruder stepped into the ring of light with him, he had to stifle a scream.

Its chin was caked with blood, new and old. There was blood on its shirt front, staining the brown tweed jacket and enhancing the red in the bowtie. What really made him want to scream were the eyes. They were solid black, and followed his every move. He pressed himself further back against the wall, hoping to get away from this… creature. It definitely wasn't human. It moved with the grace of a predator, and licked its lips in anticipation. The guard eyed the exit, but the creature saw his glance and chuckled.

"You aren't going anywhere without my permission." It whispered with malice, but the voice seemed to echo in his head.

The guard bolted for the door, dodging around the creature and sprinting as fast as he could go. But the creature was in front of him in an instant, and grabbed his throat in a chokehold. It lifted him up, so his feet were dangling, and growled, "I told you. You aren't going anywhere without my permission." It slammed the guard onto the ground, his head smacking painfully against the marble floor. Stars danced across his vision, and he groaned in pain.

The creature bent down, his rancid breath once again in his face. "Stupid human. Your race is so incompetent, yet your blood is delectable."

The guard's eyes widened at this comment, and he tried to scramble up off the floor. The creature straightened up and put its foot on his chest, holding him down. He bent down again, this time grabbing the front of his uniform, and hauled him up off the floor, so they were face to face. The creature grinned evilly, baring his teeth. The guard was suppressing a scream, but his hands were visibly shaking.

"I'm going to kill you now, Mr. Security Guard. I want you to scream as I sink my teeth into your neck, I want you to scream as loud as you can as I drain every drop of blood from you."

So when the creature lunged for his throat, he complied with every ounce of his being. His bloodcurdling scream echoed off the walls, and was music to the demon's ears.
