If you need google to solve a riddle, you suck at life. It took me all of about 30 seconds to figure out the problem, and maybe a minute to think of all the second and third questions I'd need to ask in each possible scenario. It's not that difficult really.

EDIT: Rowan, for simplicity's sake, assume it was Aletheia explaining the rules before they disguised themselves, rest assured they won't kill you unless you deserve it. Probably. I hear their orgies do get kind of... anyways that's not important.
