"That's the trick, isn't it..." His raspy voice gets softer, and any smile fades away. "Blend in, look normal, but you can't... live like they can, because you can't settle down, or get attached, or else..." He pauses, shakes his head, and suddenly he's dropped low and whirls in, a snakelike movement that, if it works, will smack Nick in the legs with the flat of the blade. One advantage of a single-edged sword is he can turn it if he needs to and keep from cutting him, that way.
