The episode turns the emotional dial slowly, then all at once, like a kettle that has been patient for far too long. A question that has been nagging since S02E05 finally gets the answer it deserves. Wembley enters the story, and the cast list gets a little more dangerous. "Yes, I think I am." is the kind of line people quote at dinner parties to seem mysterious. Good enough that your phone stays in your pocket. Mostly.
