When the whole 2001 aftermath has Roy Scheider assuaging his guilt with a wrench, an unexpected offer to join a Russian mission to the Discovery is too tempting for him to pass up. But when he finally gets to space and war breaks out on earth, the two crews have to work together in pursuit of an unambiguously happy ending. Where does Helen Mirren fall on the scale of Russian accents? What’s the creepiest thing you could hear on a huge mostly empty spaceship? Which department has very specific messaging on their inspirational poster? It’s the episode that appreciates a bit of cold-war bullshit.
