When everything has turned to black

You don't know where to go

You need something

To justify your soul

Black, Kari Kimmel

...

It had been six months since the angels fell and Dean pulled Sam out of that church in the middle of nowhere. Six months since they locked the King of Hell in the dungeon back at the bunker. Six months since they left Garth in charge of keeping a close eye on Kevin. Six months since Dean nearly lost Sam, again. Six months since he lost his best friend.

...

The world moves on because the world survives on rules. Red means stop, say you are sorry when you are in the wrong, look both ways when crossing the street and most important, the world doesn't end until the Winchester brothers say it is time.

The Winchesters live by their own set of rules. There are the loud and clear ones like driver picks the music and shotgun shuts his cake hole, do not forget Dean's pie, and in general angels are dicks. But there are also unspoken rules. At the top of that list is Sam. As in protect Sam at all cost. Once this was their father's rule and Dean is not entirely sure when it became his rule, his reason for living. But now with Bobby and, the other, gone Sam was his only reason for living.

Another one of the unspoken rules was that Dean always, always, took the bed closest to the door when they were on the road. This put him between Sam and anything trying to get in the room.

There was a knock at the door.
