Jinah spends the episode gathering suspicions the way some people collect stamps, carefully, obsessively, and with the strong feeling that one of them is about to bite. Special mention goes to survivors, which gets more screen time than some of the cast. Meet Jinah, who has the air of someone who will be very important or very dead. It lacks the spark of E02, as if someone forgot to recharge it. Of all the things said this week, "Was it just... a dream?" is the one that will follow you to bed. Good television, quietly doing its job.
