There is a generous helping of flashbacks, served cold. The dialogue this week has timing; some of the jokes land a beat late, like thunder after good lightning. The line of the week goes to "We had to leave before he woke up.", which deserves to be embroidered on a cushion. Long-time viewers get a payoff: "Why'd you think he'd help you anyway? He wasn't exactly y..." is no longer a mystery. Reliable, like a well-made chair.
