Day 8:
Archangels still crying.
Sam and Adam worked together and carved the brimstone into chess pieces. It was a very rewarding family bonding experience.
Sam realized he had never played chess with Dean. Dean either didn't like chess or didn't know how to play. Probably both.
Day 9:
No change in the archangels.
"Checkmate." Adam said.
"Shit." Cursed Sam.
Day 10:
Lucifer journeyed over to Sam and Adam, who weren't bored of chess yet.
The Devil learned that chess cannot be played three ways.
Day 11:
"What is this game?" Michael asked.
"It's called chess." Adam spoke up. It seemed fitting enough that Adam usually responded to Michael and Sam to Lucifer.
Sam pushed a pawn forward and Adam scowled at the board.
"Can I play?" Asked the good (good being a relative term) archangel.
"Don't bother." Lucifer grumbled, ""Chess can't be played three ways"!"
"It can't!" Sam insisted.
"Why don't you build your own chessboard?" Adam suggested.
Day 12:
The archangels used their collective archangel-y powers to make the Cage into a chess house.
Of course, it being the cage, they had certain limitations on their Graces and the chess house had to be made of cracked stone, crumbling into ruins. The center chessboard big enough for standing people instead of chess pieces was set with the corpses of the people Sam and Adam loved.
However, it was a chess house.
The archangels beamed with pride.
Day 13:
Adam and Sam taught Michael and Lucifer how to play chess.
Day 14:
Michael and Lucifer immediately started playing chess with new rules; somehow moving around any piece on the far left of the board signified the creation of a new species. Somehow.
Both humans got the impression that the angels liked to play God.
