At the end of the kitchen/dining room scene, they frame Roger's head with the arch in the background. Well, I thought it was slightly interesting. Promo for "The Invaders"! With Roy Thinnes...
All the mystery regarding Laura and the nature of her connection to / influence on David was well handled. Now, this storyline is blending in with other DS storylines, in my head, but when I first saw the first Laura story, over the holidays (Xmas 2011), it was a very strange feeling, watching something like this happen for the first time on DS.
