True Blood, Season 2

Sophie-Anne:
Maenads are sad, silly things. The world changed centuries ago and they're still waiting for the God who comes.

Bill:
Does he ever come?

Sophie-Anne:
Of course not. Gods never actually show up. They only exist in humans' minds, like money and morality.

Bill:
If I can't kill her, how do I get her to leave Bon Temps?

Sophie-Anne:
She has to believe that she successfully summoned forth Dionysus in hopes that he will ravish her and quite literally devour her until she's lost into oblivion.

Bill:
So she seeks death? The true death. The one thing she has evolved beyond.

Sophie-Anne:
Ironic, isn't it? You know they're really not that smart, these maenads.

Bill:
So how does she summon this non-existent god of hers?

Sophie-Anne:
I never said he was non-existent. I just said he never comes. She believes if she finds the perfect vessel, sacrifices and devours part of him or her, plus surrounded by the magic of her familiars than her mad god will appear. At that point when she willingly surrenders herself to him...

Bill:
That's the only point she can be killed.
