I think that may have been true last season, but the first couple episodes of this season he's been starkly different and if anything they've been too heavy on what he's learned. The show has always turned on the recklessness of Don and Roger, and both are over the hump and into their decline (Don now is essentially Roger when we first met him). The fault of the show (or maybe the intent, but it's making life difficult for them now) is they were never able to develop the younger generation into interesting, fully dimensional, people. Peggy was the obvious choice to become the central young character, but her development has been almost non-existent. Even poor battered Joanie has more depth (no jokes!) than she. And of course Pete has been lost in space for years -- though to be fair building his character into a truly multifaceted, complex person you'd want to explore would have taken the exceptional writing of a playwright or a novelist, not a TV writer.
