Core, now under her married name of Persephone, is a force to be reckoned with, and not always a nice one. The level of power she now has is, frankly, staggering. And she seems to use that power quite easily, and to bring about fear in people.
When people speak of Hades, it’s usually with respect, and by calling him “mighty.” Persephone, though, is a different story. She is seen, not unlike Galadriel, as a beautiful and terrible queen. Odysseus, who openly flaunted Poseidon’s power and deliberately blinded his son Polyphemus is wary of Persephone’s great power: “does Proserpine want to lay a still further load of grief upon me” he asks of his mother.
From that line, we can tell that he believes Persephone (Proserpine is the Roman spelling) is the one who hands down harsh punishments. She and Hades share this realm, but she is the one Odysseus attributes responsibility to for his grief.
A little more explanation about that. It’s important to note that Odysseus isn’t actually suffering from anything done by Persephone. Rather, it’s that the automatically assigns the responsibility to her that’s more important. He does this readily, which tells us that Persephone has this reputation about her.
We aren’t privy much to Core’s temperament prior to the kidnaping, and the crying seems very girlish, but that girl from before is not who she is now. Now she is Persephone, the Queen of the Underworld. She is powerful, sometimes cruel, and has no problem with making people suffer (again, an extension of how Odysseus readily assigns blame).
Persephone is almost always referred to as the Queen of the Underworld, yet Hades is seldom referred to as the King of the Underworld. The only king readily within the Greek pantheon is actually Zeus as King of the Gods. It’s interesting that she would have the title of Queen, then, denoting not just the elevated power she now has, but also the status.
