"Well...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".
