Hi,
This story takes place at Bobby's. Sam is having nightmares and I believe hanging on to Dean's leather jacket.
Bobby is explaining to Dean how Castiel is lying to them.
Dean remembers Death saying it's about the souls and realizes what Sam's nightmares are. Castiel is attempting to take Sam's soul for the war in heaven.
When Dean confronts him, God sends two guardian angels to fight off the demons and other angels who were there to take the soul.
Bobby describes one of the angels as 5ft, red hair and kicking the other's butts.
Thanks everyone
