Jellal and Erza are saved from Millianna's wrath when Ultear comes to their aid, explaining to the woman that she is the evil behind the Tower of Heaven incident.

Concurrently, Gray falls to one of Motherglare's minions protecting Juvia, and Ultear decides she no longer deserves to live after the darkness she has brought to those around her.
