To be accepted as Yaga's pupil, Seth must prove his strength as a sorcerer. He asks Melie for help, but attack magic isn't her strong suit, so she tells him she can't help... but her worry for Seth causes her personality to take a drastic turn into "Crazy Melie." She teaches Seth the harsh and dangerous lesson that strength can't be gained unless you're prepared to die for it, but then things go horribly wrong...

di personalità, ricordi?
