After rescuing Horn, Diablo learns of Horn's secret. Meanwhile, Shera, Rem, and Lumachina make progress through the dungeon and reach the twelfth underground floor.

Return all to white, White Nova!
Alles soll ins Weiße zurückkehren, White Nova!
Apporte la mort sur ce monde,
White Nova !
Che tutto ritorni al bianco!
Volte tudo ao branco, White Nova!
Сотри всё на своём пути…
Белая вспышка!
