Since speculation and theories were starting to become prominent on this thread (and I don't want it to happen, since I'd like it to stay focused on "general" discussion as the word says) I created a sola - Speculation & Theories
The purpose of that thread is to host speculation and theories about the series that can't find a place in the episode discussion threads, leaving the general thread clean.
I moved there all the posts of the last 2 days. Some of there were extremely well written. Please remain there (or on episode threads) from now on for speculations. Thanks
