Something with the slides...
I noticed something interesting regarding the slides for this episode and future ones. You can easily see how each nest episode is more ''colder'' than the previous one. First episode resembles rain and reminds of early autumn, ep. 2 is more yellowish and resembles Octobre or so, ep. 3 is much more reddish and brownish resembling late autumn (novembre or so), ep. 4 jumps out a little bit, but it still can be connected to transition from autumn to winter, night which is the longest in this time period, and ep. 5 obviously resembles true winter. So when you look at it you see a very slow transition from autumn to winter. I thought of it just today and noticed it, some of probably noticed this earlier. Maybe there is some hidden meaning behind it? Or it just simply means that the season will take place in this time of the year (autumn/winter).
