Now for my observation as to what we see in the video. Take with a grain of salt. I know from simple fan video making that's it's easy to piece clips together and make things seem not as they really are.
Add into that mix, clips of dream sequences and nothing is a sure thing! I added in a few of the transcriptions in itallic here and there. And I'm not always sure of whom or what, ergo the question-marks.
I'm sure I missed many things in the observations, but that's the breakdown as I perceived it. Guess we'll have to wait till January 2012 to see how this all plays out, eh readers? ;)
