Amy: This episode wrapped its themes around itself so tightly the drama could have suffocated, but in the end it never got so arch that it failed to pack a punch even though as a construction it was pretty close to immaculate and, so, highly conspicuous.

Ad: Absolutely. It was testimony to the fact that Mad Men is only superficially realistic – realism is never so overtly self-conscious of its themes, or given to blurring the lines between dream and reality, for that matter.

Amy: It’s enjoyable to watch Weiner and co unpacking the theme of change in all these different ways, isn’t it? In Mystery Date it was all about the intrusion of an unknown element into the characters’ lives – a date with someone they didn’t know, a situation they couldn’t plan for. Basically they’re all Cinderella in Michael’s commercial, aren’t they, turning round to confront the stranger? We could break it down every which way, but that’s just a bit too anal for me. I think we should just play it by ear and discuss the threads we liked most.
