This was, in this viewer's opinion, a solid "stand-alone" episode as it failed to advance the fate of the two universes, yet it opened a possibility it could be done. The special effects of the young girl's courthouse bombing was spectacularly well done adding urgency to the need to prevent what she believed was, likely, impossible. The episode displayed a lot of humanity, both uplifting and somber, and little science or technology and was a welcome change of pace even if it did not advance the viewer's insight into what will be, most certainly, playing out over the few remaining episodes.
So, one must stay tuned to see if the episode was just Olivia displaying her maternal side (she was excellent), or if is the beginning of a more driven Olivia. Either way this weeks story was a solid one if not overly revealing.
