Hmm. That implied that he'd heard of Earth but perhaps wasn't from there? Further implying that the Rocinante was a ship of some kind? "I'm afraid it is. Wherever you were, you're here now. I for example come from Melbourne in the year 1929." A bit of a gamble, but not much of one, Jack judged; 1929 was the past or a total unknown to most others here, only excepting Phryne and Miss Williams. "None of us know why or how, but we're all in the same situation."
