Last time we saw Don Draper, he had hit a wall and in such a major way that it seemed like he really had no choice but to change course. On top of that, we got the impression he was done running from himself. When he took Sally, Bobby, and Gene to a run-down former whorehouse, aka his childhood home, it looked like he was finally owning his past and his transgressions. And maybe even possibly seeking redemption (a major element creator Matthew Weiner has pointed to as a main season 7 theme).
So it's no wonder that the first time we saw Don in tonight's season premiere -- which kicks off in late January 1969 -- he was spiffying himself up, shaving, and straightening his tie to greet Megan after his transcontinental flight from New York to L.A.
