Dean whimpered in his sleep, his lips forming words that would never be spoken and his fingers twitching involuntarily. Sam, however, was not screaming from the bad dreams that so plagued him. He instead was lost to black oblivion; so far asleep he did not even snore. It was the best sleep he had gotten in months.
Castiel sat in one dark corner of the motel room, watching over his precious Winchesters. He was mainly focused on Dean—the one lock of hair that stuck out in the wrong direction; the thick eyelashes that fluttered every few seconds; the long fingers that crept under his pillow, reflexively searching for a weapon.
The nightmares that followed the hunter like a disease infected too Castiel's mind. He knew that he must not interfere, but the pathetic moans were seeping through his resolve. His trenchcoat lay haphazard on his figure and his tie was, as always, backwards.
Then he heard a sound. It did not come from the black shape of the television, nor Sam, nor himself. It was Dean. Crying.
Castiel narrowed his eyes and tilted his head to one side, as if calculating, weighing his options. If he helped, Dean would no longer cry out from the memories of Hell or Purgatory. If he did not, he would be forced to endure with agonising silence as the hunter relived the horrors again and again.
Strict rules forbade the angels from relieving their charges of these human things. Apparently, pain built character. This was something that had always bothered Castiel, even before he became acquainted with the Winchesters. Why leave humans to anguish when you could sap away the pain with just the touch of a finger?
And so he did. Castiel slowly stood up, careful not to wake them, and crossed to the bedside of the fitful hunter. "Sleep now, Dean," he whispered, and touched Dean's forehead with two fingers.
The glow that emanated from his gentle touch was bright enough to shield the gentle kiss he placed upon the hunter's lips.
