specif post hell fic
there was this fic i read a while ago where sam's wall breaks (cas didn't break it) and dean and bobby keep him in the panic room. dean notices that he mumbles stuff in enochian and when he tells cas, cas tries to talk to him, only to come to the conclusion that lucifer is still in him. i think at one part someone says that sam is the cage (tho i could be confusing this with another story?) does anyone know what this story is?
