Ok, neither of you seemed to foucus on this or if you did I may have missed it.
But do you believe that them going back in time was already a part of the existing timeline... examples of this was that Alec of the future seemed to be not suprised of the events unfolding in front of him as the device was activated and they were sent back to the past.
Also when she meets Alec in the future for the first time he says this is long over due, in other words he knew he was going to meet her, and he has been waiting for it to happen (*again).
I believe that this story is going to have no ripple affect on the future, except that when kierra does return to the future she will be fighting against the corporations, she already was learning that perhaps the needs of the people were not coming first (the food not being distributed), I believe she is the hero, but was trained to beileve that the corporations were the good, and Liber8 was evil. The methods of some of its members may be questionable at best, but their cause is truly for the people. I think we will see them get back to the future, and perhaps in another season have to change something in another time period.
I love this series so far, and am sad to see it is a 10 episode first season......but then again I also am waiitng for Alphas to return
