Azrael learns the duality of the swords. The Sword of Salvation represents the spiritual world, the soul. The Sword of Sin symbolizes the material world, the flesh. Father day and Azrael have learned that everything up until this point was pre-destined that everything that is written will come to pass. That Father Grieve will sacriface his life to save Azrael and prolong the Crusader from getting the shroud.
Finally give a name to the Killer of Saints, The Crusader.
