Interesting how Don and Peggy's stories basically paralleled. I had gone into the season thinking would see Don bottomed out and Peggy on top. Instead they're both adrift, personally and professionally. They are even both plagued by homes in need of repair.
I also really enjoyed the juxtaposition between our first scene with Don and our last scene with Don. When we first see him getting off the plane in LA he looks like the classic Draper we all know, practically in American James Bond. But then at the end he's cold lonely and pathetic, more ironweed then Goldfinger.
In regards to the rest of the show it's pretty obvious that one of the themes is how at that point in our history California was coming into its own as the Golden State whereas New York was in deep decline. As such I suppose it makes sense that Pete (who, all his flaws has a tendency to be one of the more forward thinking members of the firm) would embrace Los Angeles even if he missed Manhattan.
