The title of episode 2 of The Man in the High Castle season 3, Imagine Manchuria, refers to a line Kido says to his would-be new assistant. If Nakamura thinks San Francisco weather is unpleasant in the winter (it tends toward cool and frequently rainy), imagine what it will be like when Kido turns on him and has him sent to Manchuria, which can be as cold as the Arctic in winter. In other words, things can always get worse.
This is the theme of the episode, as the solution to one problem inevitably causes a bigger problem down the line. If we don’t see the bigger problem in this episode, we’re likely seeing the set up for it. Helen solves the Smiths’ gossip problem one way, but now has a crime scene to deal with. John solves it another way, but now has an ongoing blackmail scheme to finesse at a time when he’s being watched very closely. Kido arrests Juliana, but also catches Trudy, who he executed in the opening scenes of season 1. The triumph of catching a Resistance operative is overshadowed by the mental discord of seeing a woman he knows to be dead, now inexplicably returned to life. And of being put in conflict with Tagomi once again.
Schemes within schemes are revealed within the Reich, until anyone who has any power there might wish they’d been sent to Manchuria. In addition to his other supersecret American operations, Himmler is playing Hoover and Rockwell against Smith, and it’s anyone’s guess which side he’ll favor in the end. Joe is a Lebensborn special operative who works directly for Himmler, apparently as an assassin, but his true purpose is unknown to almost everyone. Even Smith and the head of the Reich Embassy in San Francisco, who is ostensibly his boss, don’t know. And Himmler is a demanding, impatient taskmaster who accepts no excuses.
