Watch 'Omega Man', it is a story of a man supposedly is the only one left alive after a man-made plague scorches earth and only leaves him and this weird group of light fearing zombie people. Well any-who, watch until he goes into the hotel and finds Mathieious's little zombie pal dead on a desk. He then looks real tired and sits in a couch and talks in to his recorder. Look into the glass revolving doors behind him and you should see a set crew member (janitor) wrapping a cord up. It's pretty hard to be alone on the earth when friendly janitor Bob is right in your line of sight!
