I also loved the kitchen scene with Don and Sally. It seems that the show is working to put these interactions in more often, in an effort to contrast Don’s warm and affectionate side with Betty’s icy demeanor. At least she gave Sally a small kiss on the top of her head when she greeted her and baby Eugene upon their return home.
I’m not sure if Don’s going to ultimately cheat with Sally’s teacher…if only because he tends to keep his mistresses in his work world. Say what you want, but we have yet to catch Don diddling the neighbor. There is certainly a lot of talk about him staying honest for now, but it still seems as if the damage is done in the Draper household, and there’s no going back.
