The episode hands you a puzzle, takes away two pieces, and smiles politely while you look under the sofa. There is a generous helping of flashbacks, served cold. The main story waits patiently in the car while this one runs an errand. There is a moment where someone says "If I ask where the King is, he'll get suspicious and silence us.", and the episode lets it hang in the air just long enough. Comfortably above average, and it knows it.
