Roger, can you remember the CSI Miami episode where a killer kills a girl's family by mistake (because he could not read the house number, because he was illiterate, dyslexic, or peter), and then the main guy says to her "The next time you see my face, you will know that you are safe."? He sees her at the end at a funeral for her parents: he nods; she sighs in relief and mouths a thank you, and he waltzes off like some kind of mysterious guardian angel.
