Oh, my. This final season of Justified continues to find perfectly reasonable ways to bring back old faces and beloved former characters. Tonight’s episode includes two more, portraying characters from opposite sides of the law: Mykelti Williamson as backwoods black crime lord Limehouse, and Patton Oswald (pictured) as the surprisingly resourceful and dedicated Constable Bob. They’re both terrific tonight – and so is series regular Joelle Carter as Ava Crowder, who manages to share scenes with them both. She’s been given one hell of a story line this season – and she’s proven more than up to the task, delivering one of the best female TV performances of the season.
