Yup! They explained that in the second season.
I watched first couple of episodes of 2nd season... we need a separate thread on the 2nd season 
Yes, and as I dwell deeper and deeper into the story, I realize that no dialog in this series is useless or nonsense. Each has some connection to some event about to happen or some event that has already happened. As someone who saw the episodes in the original non chronological format... I know this far better than my friends who saw them in chronological order...
