I dont think this last episode really told us anything. Some small back history on Juliette, but aside from the fact that she staged the 'being left behind' to get to the beach was the only thing new that was revealed.
We already knew about the submarine, the link to the outside, etc...we even knew that the others were keenly interested in babies, mothers and children.
Im trying to figure out, besides that, what the 'big' answers that were revealed...nothing much.
Anything you post on this BB can and will be used against you...
