A/N: I'm taking a few liberties with this, because the Beyond Magnetic EP wasn't out when this episode aired and the song is actually about suicide, but listening to it I still felt it was right for this moment.
Just A Bullet Away
It's been less than an hour since the hardware store was blown to pieces, taking Ellen and Jo with it, and already he's drowning in the guilt. He knows he's to blame, for letting the hellhound get to Jo when really it should have been him; for not finding a way to help her, and now there's nothing he can do to change things. Both of them are gone, but the least he can do is make sure they didn't die in vain.
Dean grips the Colt tight in his hand: the gun that can kill anything, and tonight will kill the Devil himself. His fingers flex about the handle, moonlight shining on the barrel of the midnight revolver. What he's about to do brings with it danger, but even the promise of that has gone dull when he knows there's only two ways for this to end. Either he turns the tables on this Apocalypse, or he dies trying.
Lucifer is standing straight before him now, and Dean raises the gun. The Devil hasn't realised he's there, instead taunting Sam, but Dean has something to say before he pulls the trigger, "Yeah? Well I'd hurt you. So suck it!"
Then bullet smashes through bone and brain, and a body crumples at his feet. Dean looks down at it, daring to believe for a moment that he's succeeded, and that they've won. Yes, you can suck on that, he thinks, as he stares at a corpse that once held a fallen angel, suck on it 'til it's gone dry.
An instant later, however, his moment of victory is shattered. Seems that the legend of the Colt that could kill anything was just one more lie.
