Death doesn't separate end life in this world, like it does for us. It's just a vacation away from life. But, what if someone suddenly didn't return? They're gone. Forever. And in Incarnate, Ana has taken the spot of the soul who was supposed to be reborn instead of her. No one is sure whether new life is good. It's not an opportunity for something wonderful as in our world, but an ending for something which was marvelous. She is their 'butterfly', their alien which has taken the place of one of their own. After all, why would they want something new when they can hold the old close to their heart and never let go?
