If canon Blaine was representative of Psyche, would that make McKinley Hades? And does that mean he has to leave again? Maybe not because he didn't go on his own, he had Kurt with him.

I don't know anything about Eros or Cupid. Do either (or both) of them have a period of sexual purity (baby penguin-ness) as part of their story? And a lead up to sexual awakening, and then some kind of public display of prowess/virility a la Not The Boy Next Door? Because that would be rad.
