What exactly where the fugitives doing in London? Was there more to Zin's plan than was revealed before the series got axed, or was it just a ploy to get Cole out of the way for a while? And even back in the US, we see close to the end that the fugitives seemed to be all over the US.
Cole knew there were fugitives outside the US when he did his mass collection in the last ep. So why did the map only show the United States?
What would the fallout have been when someone put the puzzle together and realized that over 200 people dropped dead of unexplained causes at just the same instant? They never really told us what happened with the bodies anyway, but it did have to make some people wonder. And this would only do it more.
