Tonight’s second episode of this new CBS series is titled “Extinct,” but that could be misleading: the story line seems to be heading towards a new life beginning, not an old one ending. In this hour, Sam (Camryn Manheim) gives Molly (Halle Berry) an ultrasound – the results of which could confirm Molly’s very baffling suspicions, and eerie nightmare visions, about being impregnated while on a year-long solo space flight. Let’s hope tonight’s episode is more original, and less obvious, than last week’s opener.
