Tonight’s episode brings to a head one of many killer confrontations roiling to a boil in this final season – and also finds room to use a recording of “Greensleeves” by series star Katey Sagal. It’s also the title of tonight’s episode, so expect the song to play at the end, over a montage of the latest wave of violence and the regret and pain of those left in its wake. One thing seems apparent: On every episode from now until the series finale, there will be blood.
