Has Chung followed Nick across the continent, from San Francisco to Toronto, from 1916 to 1992? Or is this a coincidental encounter?
I've always thought this was a coincidental encounter. Chung was too young to follow someone who knows how to vanish because he's running from someone else.
Are there just so few surviving witnesses?
Most certainly. Although, apparently witnesses were left by whatever preceded the flashback from "The Code". Generally I would think that either there are no witnesses or they have been taken care of sooner rather than later. Another point why there aren't more perople seeking revenge might be that they are constantly on the move. So it was kind of difficult to track them down with the means of pre-20th century technology.
