Where are people allowed to be? Where can't they be? The first half of the two parter ending Season 1 is full of all kinds of violence and gore. It would test one's belief in the rules being played by. The governments are so intent on not crossing over, they seem to be totally accepting of the actions against one another. Where is the line drawn? So we move into the second half realizing that there is cross contamination. Ultimately, that epidemic is what has fueled all this. But did the Alpha side really have anything to do with it. Was it contrived for the benefit of the power hungry. We'll see what's next.
