Stone nods and starts walking. He thinks it might be the uniform that makes people act odd around him. He doesn't get reactions like this when he's in his street clothes. He get's the feeling that Chihiro might still act like this anyway, but he isn't sure why. He stays quiet for the remainder of the walk, letting the girl get comfortable as she can.  He isn't sure what they can do to help her now, but he's damn well going to try. For now he focuses on dealing with the paper work and getting this girl out of sight.
