Having watched this video after seeing that Nikki B. thinks she's the ceremony girl, I'm a little disappointed. I'm not 100% impressed.
The thing that struck me was that she was learning French, and talked about Paris. There has been a lot of talk about "meridians". Well, where is one of the most important meridians? That's right! Paris!
Here's just a bit of info from Wikipedia:
http://en.wikipedia.org/wiki/Paris_Meridian
Henry Lincoln, in his book The Holy Place, argues that various ancient structures are aligned according to the Paris Meridian. They even include medieval churches, built long before the meridian was established according to conventional history, and Lincoln finds it obvious that the meridian "was based upon the 'cromlech intersect division line'." David Wood, in his book Genisis, likewise ascribes a deeper significance to the Paris Meridian and takes it into account when trying to decipher the geometry of the myth-encrusted village of Rennes-le-Château: The meridian passes about 350 meters (yards) west of the site of the so-called "Poussin tomb," an important location in the legends and esoteric theories relating to that place. (A skeptical discussion of these theories, including the supposed "alignments," can be found in Bill Putnam and Edwin Wood's book The Treasure of Rennes-le-Château - A mystery solved.)
And of course if you've read Dan Brown, you've heard of this meridian as well.
The girl in this video seems very, very young and slightly fragile. I don't see her fighting off the Order if they are coming for her. I almost prefer the idea of Taylor being cannon. At least she looks like she could stick up for herself a bit.
Edit to add:
And of course there is the language "that you've probably never heard of". Obviously Enochian.
One problem I really have with this is that Jules is obviously watching other videos on youtube. Has she not found LG15 and made the connection? How long til she sees Bree and realizes that she's the new girl?
