The Wheel: Don runs home and says, ‘Get in the car, we can be to your father’s by midnight,’ and it’s all happy and familial but it’s all a fantasy. In real life, Don gets home too late, they’ve already taken a cab to the train, and Don knows he has left himself empty and isolated from everything and anything he loves.

But don’t forget this: Don can still get to his father-in-law’s. The Drapers live in Ossining (about 20 minutes from where I’m sitting now). We don’t know where on the Jersey Shore Betty’s dad lives, but the furthest point is a mere three hours away. He could meet them there, have his happy scene, and they’d all drive home together after the holiday.

What stops Don, ultimately, is Don.
