SEASON FINALE: We now know that Berlin, in the context of this show, is a person, not a place – and specifically, is the person who has had Red [James Spader] in his sights for a while. All the people on “the Blacklist,” as well as some of the people around Liz (Megan Boone), Red’s off-again, on-again agency handler, are stuck somehow in Berlin’s spider web. Tonight, series producer Jon Bokenkamp promises “a game changer,” but the series already has changed the game for NBC, and helped drag the network out of its multi-year ratings slump.
