Since the first episode I was truly fascinated by the possibility of the existence of another universe, another world but still the same. Except some little details.
How many times in our life we asked to ourself: "How would been my life if I was made another choice?"
I did it (and still I do it) a lot. So the caos, so the desire to change something. Maybe traveling back in the time to tell to myself "don't do it," "Please do it!" "Keep do that and stop doing the other thing."
All this caos appear on the canvas, in what looks like a strongest energy attracting the travel machine all the way back to the past.
