E/O Challenge: Twitch
Sam blinked quickly, eyes locked on the beast before him.
The beast at whose feet lay his unconscious father.
The beast who had Dean by the throat, talons mere millimeters from puncturing his brother's skin.
Dean stared back, silent, steady, mentally conveying calmness and control to Sam.
Sam's finger twitched slightly on the trigger of his glock, ready to fire when he had a clear shot.
A clear shot that may never come, but one that must be taken to save Dean's life.
Dean's stare changed to one Sam recognized instantly: I trust you, Sammy.
Needing only that, Sam fired.
