Meh.... WTH was that? And no continuation next week? So what exactly was the point???
It has become the norm for these series spanning mythology shows to introduce and set up pieces for down the road and set them aside until the right moment to reintroduce them once they have set up other interrelated pieces in order not to ruin surprises to come--if you ever watched LOST they did that all the time. Sometimes it would be years before they revisited something that was brought up and then seemingly forgotten.
Frankly that kind of storytelling isn't very satisfying but thanks to LOST non linear storytelling is all the rage it would seem these days.
