Persephone ?????

In the movie it is said that; "he (Hades) forced Persephone to marry him. Keeps her prisoner, she hates it there so she has 'secret' visitors. She keeps the pearls hidden for them all over the world and these pearls provide a quick exit from the underworld.”
I couldn’t find a lot on Persephone except for this;
Persephone, The only daughter of the goddess Demeter. While Persephone was out picking flowers, a chasm opened revealing Pluto. He quickly pulled her into the underworld and made her his wife and Queen of the Lower World. Demeter scoured the land looking for her daughter and once she discovered what had occurred, she was grief-stricken. She wandered the land alone, bringing famine to the earth in her grief. The people called out to Zeus for assistance and he answered by ordering Hades to release Persephone. However she had already eaten a pomegranate seed. Having fed upon and drank from the goods of the underworld, she was obligated to spend a third of the year with Pluto. When winter came and earth was cold and barren is the time Persephone resides in the underworld and Demeter travels the earth yearning for her only daughter. At Persephone's release in the spring, the earth begins to grow flowers again.

I can honestly say I do not believe it to be Persephone's fault, She did not will her kidnapping. Persephone did not have a choice as a Young and probably Naive girl.

Does it show the mother Demeter was irresponsible for leaving her daughter Persephone alone?

Perhaps, However I think the mother had believed her daughter Persephone would be safe. After all there is no reason for Pluto to Pick flowers. Unfortunately he found Persephone though. Demeter clearly cares and loves her daughter Persephone, to be searching for her.

Which doesn’t really match the description given in the movie, so I then Google searched Hades wife and I found this description;

Hera is Zeus wife and sister. She was raised by the Titans Ocean and Tethys. She is the protector of marrage and takes special care of married women.
Hera's marriage was founded in strife with Zeus and continued in strife. Zeus courted her unsuccesfully. He then turned to trickery, changing himself into disheveled cuckoo. Hera feeling sorry for the bird held it to her breast to warm it. Zues then resumed his normal form and taking advantage of the suprise he gained, raped her. She then married him to cover her shame.
Once when Zeus was being partcularly overbearing to the other gods, Hera convinced them to join in a revolt. Her part in the revolt was to drug Zeus, and in this she was successful. The gods then bound the sleeping Zeus to a couch taking care to tie many knots. This done they began to quarrel over the next step. Briareus overheard the arguements. Still full of gratitude to Zeus, Briareus slipped in and was able to quickly untie the many knots. Zeus sprang from the couch and grapped up his thuderbolt. The gods fell to their knees begging and pleading for mercy. He seized Hera and hung her from the sky with gold chains. She wept in pain all night but, none of the others dared to interfere. Her weeping kept Zeus up and the next morning he agreed to release her if she would swear never to rebel again. She had little choice but, to agree. While she never again rebeled, she often intrigued against Zeus's plans and she was often able to outwit him.
Most stories concerning Hera have to do with her jealous revenge for Zeus's infidelities. Her sacred animals are the cow and the peacock. Her favorite city is Argos.

Which matches up the description in the movie better, so as a guess I’m thinking that the director or who ever combined the two people in Greek mythology and make them one character in the movie, also there is nothing mentioned about Persephone’s pearls, so again I am guessing that that was but in there as a way of the main characters to get out of the underworld.
