Part 2 of the 4-part "Children & Monsters." When a mysterious stranger tracks down British school-girl Elaine Belloc and claims to be her father, a nasty secret unravels that begins to claim lives. Meanwhile, the infinite legions of the Heavenly Host prepare for an epic battle with Lucifer who is still in the midst of organizing a ruthless army of his own.
We meet a new and very sick man called Sandalphon, a man using a mentally disabled young boy to do his bidding, by telling him lies about what it is he is doing, destroying the young man before he has a chance to grow. Lucifer also brings back an old friend, adding her as extra protection to his gateway as Amenadiel prepares the legions of Heaven to take out the Lux. Elaine Belloc is located by a man claiming to be her father, but he seems to have gotten himself into trouble when an angel comes to kill him.
