MIDSEASON FINALE: Last week’s episode ended with a rare moment of tenderness between Don (Jon Hamm) and Peggy (Elisabeth Moss). Tonight, even though it’s Memorial Day weekend, and many shows are taking the week off, Mad Men is continuing with a new episode as scheduled – basically because it’s going on an extended vacation anyway. After tonight’s seventh episode of the series’ final series, Mad Men is going on hiatus until next year, when it will present the last seven hours in the story of Don Draper. What to expect tonight? At the very least, some sort of a cliffhanger.
