followers to imprison him. However, Cassidy manages to convince the Children of Blood about the truth of their master, and after secretly turning them all into vampires, they turn against Eccarius and devour him. After telling the Children of Blood that they are free to explore the world, Hoover shows up and hides with Cassidy under an umbrella, as the Grail removes the roof of the building, killing all of the Children of Blood (but for two members hidden in coffins), before knocking out Cassidy with a tranquilliser, and bringing him to Masada, the Grail headquarters. At the headquarters, Starr kills Hoover and plans to torture Cassidy, lure Jesse to the base, and kill him, having turned against his previous plan for Jesse to serve as the Grail's new messiah.

In the present, when Cassidy's angel cellmate
