You know, Doc, when something happens, it can leave a trace of itself behind. Say like if someone burns toast. Well, maybe things that happen leave other kind of traces behind. Not things that anyone can notice, but things that people who shine can see. Just like they can see things that haven't happened yet, well, sometimes they can see things that happened a long time ago. I think a lot of things happened right here in this particular hotel over the years, and not all of 'em was good.
