chunk: The next morning, Priest, Priestess and Hicks arrive in Jericho and discover the town empty and the three dead Priests crucified. Priest and Priestess share an intimate moment where she makes her move, hoping that now that Shannon has died, he would no longer feel bound to her. Priest, who is clearly not over Shannon, gently refuses. Priest realizes that the vampires have been using the trains to travel by day and attack the free towns by night, with the walled cities at the end of the train line. Hicks believes an attack on the cities would be unwise because of the sun, but Priest reveals that factories, producing massive clouds of smoke and ash, have permanently deprived the city of sunlight, so the vampire attack would be a slaughter.
