“Forensics had taught her that scars left tissue much tougher than skin.”

“Scar tissue has no character. It's not like skin. It doesn't show age or illness or pallor or tan. It has no pores, no hair, no wrinkles. It's like a slip cover. It shields and disguises what's beneath. That's why we grow it; we have something to hide. ”

“The worst type of crying wasn't the kind everyone could see--the wailing on street corners, the tearing at clothes. No, the worst kind happened when your soul wept and no matter what you did, there was no way to comfort it. A section withered and became a scar on the part of your soul that survived. For people like me and Echo, our souls contained more scar tissue than life.”
