You duck into an old storm drain. As you walk down deeper into the drain you notice messages spray painted on the wall. They are addressed to either Bob or Ema. You ask the dark man "Who is Bob and who is Ema?".
"Bob is the dude who owns this place and Ema is his lay." He answers then pauses for a moment to examine the confused look on your face before explaining further."Ema pimps the hookers and stuff. Bob takes care of the rest.
