It wasn't much. When you looked back, remembered all the things that led up to this moment, every action and reaction that brought us to where we are right now, the first moment, first domino to fall, was tiny. Insignificant. Barely worth mentioning. The universe is vast, full of unimaginable things. Enormous changes and rifts, ideas and discoveries opening and shaping the very future of existence, and yet, this miniscule moment, the fleeting thought, whipped away and cast into the recesses of the universe, mattered. It changed everything, created the world we live in today. It was the beginning of something incomprehensible, something huge. It was a spark, simple as that. A tiny, gleaming spark of light, barely discernible beneath the pain and grime. It was that one spark, one ridiculously small, dismissible piece of that that changed the world. One spark that made an angel pause, made an angel think, consider. One glimpse of a corner of the tainted soul. Made the angel curious, made the angel carefully reach for the filthy soul, bring it close, look beneath the years of torture and anger, pain and fear. One touch, and the soul sang. The angel's touch, the smallest brush of grace on soul, and the filth sloughed off, slipped into the darkness, and the soul gleamed. It flashed and sparked and shined, brilliant in the dark, beautiful. Precious. Worthy. One spark was what started it all. One spark made an angel pause. One glimpse of Dean Winchester's soul changed the world.
