Kate and Simon face down a couple of occasionally patchy but still fascinating episodes with the help of the brilliant (Dr.!) Sara Ann Swain: “The Man Behind the Glass” and “Laura’s Secret Diary.” Of note this week: missing Bobby and Shelley (and conscious Audrey), Slavoj Žižek and his feelings about flowers/anatomy, Albert’s showstopping monologue, the Josie problem, the series’ use of soap opera tropes and actors, and a whole lot more.
