A/N:This prologue takes place sometime in S9 between Bloodlines (E20) and King of the Damned (E21)
Sammy…
The voice was so faint, Sam wasn't sure if he was even hearing it, or if it was just in his head. He turned his flashlight down the unlit corridor of the warehouse where he and Dean had come to investigate...something. Sam couldn't remember what exactly, or where Dean had gone, though he was sure the voice he heard was not his brother. At the end of the corridor he could now see a faint yellow-orange light flickering and he frowned. Candlelight? Or fire?
He moved cautiously down the trash-strewn, concrete hallway that smelled of damp and a faint scent of urine, keeping his gun and flashlight carefully balanced and straining to hear any further sounds. A skittering sound behind him had him turning his flashlight on a pair of startled rats attacking the remains of an pizza box. He kept on moving, carefully placing each foot to keep sound to a minimum. As he got closer to the source of the light, he could hear a crackling sound and labored breathing. The rusted metal door in front of him was partially ajar, and he pushed it open gently with one foot, wincing at the indignant squeal of the hinges.
The large room behind the door was mostly empty save for a ring of fire in the center. Inside the flaming circle lay a human-looking figure wrapped in a ragged gray blanket with their back to the door, curled in a fetal position. Sam's forehead creased in confusion - was this holy oil? Who was trapped inside? But he couldn't see the figure clearly enough. He might have to break the circle in order to find out who this was, and he wasn't going to do that without Dean present in case the prisoner was unfriendly.
He turned to go find his brother, when an almighty crash startled him. Flailing in shock, Sam fought against an unseen attacker, which turned out to be a sheet and his pillow. He stared around his room in confusion, the strange dream fading under the onslaught of cursing coming from somewhere in the bunker. Sighing, he rose and went to find out what new chaos had descended.
