I, for one, thought this would be something good for Settlers to know from the get-go. With so much risk, why did SA feel the consequences of exposure were something to be concealed until there was not choice but to drag people like Monica and me into their secret beige meeting room and scare us half to death after we'd screwed up? It made about as much sense as extremely conservative parents not telling their daughters about the consequences of sex until after they were already pregnant. Shutting the barn door after the horse was loose, much?
But then, I was beginning to think SA wasn't nearly as smart as they believed themselves to be. Our remaining undiscovered for so long seemed due more to humanity's tendency not to see things they didn't want to see, rather than cleverness on the part of Settler's Affairs.
