Re: Underworld Blossom
I like the orange, personally. It adds some of her warmth to the cold of the underworld. And since she was gathering flowers when Hades abducted her, the flower speaks of her being newly arrived - as opposed to her later role as the rather more imposing Queen of the Underworld.
As for Cerberus being happy, why shouldn't he? He's Hades' loyal watchdog, and his master adores Persephone. Sure he feasts on the flesh of the living who try to sneak past him, but he's also got a history of a weakness for sweets and music. What such beast wouldn't be charmed by Persephone?
