SEASON FINALE: Peggy has called Don a monster. Sally has caught Don with another man’s wife. Other characters have been touched on the knee, shot in the face, gotten double duty on TV by donning a blonde wig, or just responded to a bad stretch by curling up in the fetal position. And tonight, after all that, comes the season finale. How can you not watch?
