1. A decent arc for Joan. She didn’t have much to do during the first half of Season 7; and it was hard to watch her turning on Don so completely. (Remember them, sitting together in a Christmas-decorated bar? Or in the hospital waiting room? Ah, “Mad Men,” I shall miss you so very much.) I love Christina Hendricks’ silky-voiced coolness in this role, but I’d like to see something startling — something good — happen to Joan before we say goodbye.
2. The return of Sal (Bryan Batt). Oh, please? Maybe he’s started his own agency? Or become, I don’t know, a Broadway producer?
