Suddenly, Luna flies in and tells the Princesses that Quita Moz wants to see them. The three of them set off for Vallestrella. Elena and Isabel arrive at Quita Moz's place on Luna. Once they're inside, Quita Moz appears before them. Quita Moz tells Elena the time for her test has come. He also tells Elena the flames showed him Isabel on the throne.
