...Remember when three episodes before the end of S5 we all found out Brady killed Jess? She was baking cookies.
The song that 13x21 had me thinking of is "Beat the Devil's Tattoo" by Black Rebel Motorcycle Club, which first came out shortly before the end of S5, making it one of the very first songs I ever associated with SPN. It seems fitting to bring it back now:
Your soul is able, death is all you cradle
Sleeping on the nails, there’s nowhere left to fall
You have admired, every man desires
Everyone is king when there’s no one left to pawn
There is no peace here, war is never cheap dear
Love will never meet it, it just gets sold for parts
You cannot fight it, all the world denies it
Open up your eyelids and let your demons run
Sam, making that choice (which wasn't a choice). Lucifer, aspiring to kingship as usual, even as Castiel and Gabriel discuss the distinct lack of pawns remaining in Heaven. War, in Apocalypse world. Grace, and the selling off of parts that power rifts and interdimensional can openers.
Sam, eyes open and alive. It seems your soul is able, indeed.
