It had been maybe an hour after Amara, or rather the being known as The Darkness who was also God's sister, had brought Mary back from the dead after she had been killed by Azazel on the night of Wednesday, 2nd November 1983.
It certainly had been an interesting experience to witness and you had returned to the Men of Letters bunker in Lebanon, Kansas, United States of America but on top of that, Sam, Mary's youngest son and Dean's younger brother was missing and so was the angel Castiel.
"Sam?" She called out as she looked around for the taller Winchester brother yet no no response came. She then watched as Dean moved into the library and down one of the hallways as Mary stepped into the library for herself.
You were also worried for Sam and Castiel's safety unsure where either of them were and chose to remain with Mary only wanting to make sure she was also okay after what events had just transpired.
That's when the door opened and a familiar voice to you was heard, it was Castiel and he had returned after being banished from the bunker by Lady Antonia "Toni" Bevell, a member of the British Men of Letters, the reason why Sam was missing and a future adversary to you, Sam, Dean, Mary and Castiel.
