Well, it seems like the mysterious man who both wants Booker to rescue Elizabeth and knows where the city is could easily be less devious. You could easily say that, due to the conflict within the city, parts of it dropped off to the Earth and left an almost easily traceable path to the city. Who's to say the person isn't her father, finally finding the location, but unlike Mark Meltzer, being smart enough to know the danger of attempting the rescue himself. We'll have to see when BioShock Infinite comes out.
