The best part about Ted (well, about Kevin Rahm, who plays Ted), though, is his utter lack of stoicism. Don is so unreadable; Burt is a walking mystery. Joan has mastered the art of people-pleasing, and Betty thinks detachment is next to godliness. But Ted? Ted is the most expressive Mad Men character ever. He’s all raised eyebrows and agape jaws, bouncing from elation to exhaustion in a single scene.
