Where is the fifth season of The Americans taking us? With just one episode left, this slow-burn season is still largely a mystery. But let's start with Oleg, whose storyline has done a funny kind of double-work: While Philip and Elizabeth loyally serve the KGB in the States (with Elizabeth, at any rate, closing her eyes to its flaws), Oleg is witnessing the KGB's perfidy as well as its irrelevance back in the Soviet Union. For an organization that baselessly locked up his mother (who survived by sexually servicing the camp doctor), hints are dropping that the KGB, which once was powerful, is increasingly beside the point.
