There is a moment where someone says "There's no way she can trace that photo back to me, can she?", and the episode lets it hang in the air just long enough. It is a heavy episode, the kind that sits on your chest like a well-meaning cat. It also finally answers a question from S01E01, "Why don't we just jump right in? Anybody got any questions?", so patience pays, eventually. Meet Yeah, who has the air of someone who will be very important or very dead. Good television, quietly doing its job.
