Sky of fear
Dean has never known fear like he does in this moment.
A year on Death Row, thirty years of torture in the Pit, and still he's never been so afraid.
Here, with a cloud of hell-spawned light circling around Sam, seeking a way in, Sam's eyes wide and fearful as his demon-marked blood calls to its source.
Dean's grip tightens on his weapon, steeling himself to keep a promise he never wanted to make.
Then the light swirls upwards and out the shattered windows into the night.
Relief-weakened knees deposit him hard on the ground as he drops Ruby's knife.
