Pohaku said something I couldn't make out—probably a code word of some kind—and rapped a rhythmic sequence on the door. (Why not just look through the viewer lens? Think about it, chummer. Bad guy on the outside waits for that little viewer to go dark—telling him the good guy's eye is up against said viewer—and sends a round or two right through it. Ouch.) I didn't hear the countersign, but I could hear the answering rap code; it sounded like a musical quote from Take Five .
