I hope I see both girls take fate into their own hands and unite against the prince. Psyche can humanize Medea while Medea can strengthen Psyche. I think a combination of their personalities would balance out their flaws.
OH MY FLIPPING GOD!?!?!?!?!??! WHAT WAS THAT!?!?!??! UGH! Medea is the IDEAL female lead, level headed, smart, beautiful, strong and even though people think her inhumane she clearly has compassion. SO BAD ASS!
