Robert should have expected that someone would have shown up at all. Yet it still raised the little hair on his arms when he suddenly heard the deep male voice behind him and he twitched almost imperceptibly before turning around to face the guy. He wasn't put at ease by his uniform nor by the attempt at friendliness. Being the shorter of the two gave him a nervous feeling as well.
"I'm sorry," he said reflexively before realizing he said anything in return. He wasn't sure what to say next that wouldn't make him sound crazy but then he noticed the scrubs and badge. He still needed information on 807, maybe this was his way in? Not that he was skilled enough to really know how... "Are you new?" he asked hopefully.
