Medea? Love, betrayal, greed, vengeance . . . .
Medea is Jason's (the Argonaut) wife. She helped him win the Golden Fleece from her father, who did his best to get Jason killed (but that's another story for another day), and in doing so, was forced to leave her home, royal position and family. She became Jason's wife and bore him two children.
Some years later, Jason decides to set her aside and marry a younger wife.
Medea is understandably and royally pissed.
And payback is a bitch
