Persephone, the wife of Hades, lived one-third of the year in the Underworld with him and the other two-thirds of the year on Earth with her mother, Demeter.
With two sides to his personality, Dionysus represents joy, ecstasy and merriment, but also brutal and blinding rage, representing the dual effects of overindulgence.
Yep, total power move, swallowing the wife. Zeus could also, from his commanding position in the sky, blast any human or monster with his lightning bolt.
