The first time that Aizen tried to get her to eat, he sent an arrancar to her chambers, bearing a small ebony bowl. Inside it were three perfect pomegranates, ripe with a heady flush. She'd screamed, and thrown the bowl across the room, nearly decapitating an unsuspecting Ulquiorra.
Aizen was an educated man, so it couldn't have been coincidental. For that alone, she refused to eat for another three days. Later, Orihime wondered, briefly, if she should have saved the small knife sent with the bowl.
But no matter. Persephone would still rebel.
Same drill as before, etc, etc. As you'll be able to tell, I'm inordinately fond of the legend of Hades and Persephone...although it doesn't completely apply here...but it's close enough? And even though it's probably unlikely that Orihime would be well-versed in Greco-Roman mythology, I like to think that one mythological princess would recognize another.
