Ghosts
compassiisms
The question comes up in her mind, time to time, which is more interesting: the physical or the Fade? Demons and spirits are fascinated by the land of mortals with its hard rules and immutability, mortals fascinated with the Fade for its fluidity, its relative reality. The grass is always greener, or whatever it is they say in their infinite wisdom. Whoever they are. Whenever and wherever and whyever they said it.
Depending upon your frame of reference -- physical or Fade -- which realm is more interesting is obvious -- Fade or physical.
She wants to reference from every frame, though.
Obvious answers are uninteresting by default.
The best place to objectively observe two places is from the crossroads between, and far superior to weighing the pros and cons to each of two opposites is slamming them together to see what kind of sparks you get from the friction.
Better than learning how a thing works is seeing what happens when it doesn't.
Better than learning the rules is seeing what they look like broken.
That's what makes the spirit-boy-not-a-boy interesting. That's why she watches and waits, weighs options and plans approaches, observes him in his fights, with his friends, when he kills, when he saves.
She lives for the space in-between alive and dead, kind and cold, wise and brash, young and old, sudden and still, guile and guilt. She is made of polar opposites, forever vascillating between poles, undecided, never decided, until the moment she decides -- but tomorrow she may choose the other way.
She hovers in a place in-between things, and so does he. Doesn't mean they're the same, though.
She could tear him apart at the seams to see what he's stuffed with, or watch the world do it for her, or watch the way he operates within the world unmeddled with, or assert herself and do some meddling just to see. She has plans upon plans upon plans for each, but remains in-between decisions (help or hurt? plan or improvise? play fair or mark the cards?)
In minutes or hours or days she'll choose, and explode into action or manipulate the action around him or watch the action unfold on its own -- something, anything, a thousand things, but never lose interest.
Because he's the opposite of obvious, and that's as interesting as it gets.
So she follows like a ghost. And she watches.
