In a flashback to Mother Superion's time as the warrior nun, her recklessness is put on display, leading to the halo rejecting her. She explains to Ava her arrogance as a warning in the hopes she will put her trust in her sisters, as she had failed to do. The nuns discuss the best course of action to stop Adriel. Camila communicates directly to Adriel, who tries to entice her over to his side, but Camila rebuffs him. Michael tells Ava that he harbors a divinium bomb that he needs her to ignite in order to kill Adriel. Pope Duretti is now a prisoner of his second-in-command William, who has been brainwashed by Adriel into fealty. Adriel meets with Vincent and extrapolates on his plan to usher in a new world to save humanity from themselves, who voices his growing disagreement with the methods being used to procure it. The nuns plan their assault on Adriel's followers and how they will infiltrate his cathedral. As the halo loses power again, stopping and restarting, Ava encounters Lilith, who provides opposition in her attempt to interrupt the energy flow Adriel is gathering from people's prayers. Adriel uses Pope Duretti to try and legitimize himself, who is then burned to death by the energy emanating from Adriel's cathedral. Beatrice stops Ava from detonating the bomb and saving her life, but cannot retrieve the crown, as an all out battle between the OCS and FBC commences.
