This evenly paced, action-packed episode is verging on the horror. Helena has a knack for darkening every episode with her feral nature and all the awful things that happen to her. We also get our chain of command updated, introducing Rachel as just another one of the clones, with Dr. Leekie at the very top now, but that definitely won’t last for long once we find out what who Mrs. S is trying to protect Sarah from.
