I think Betty needs to chill with the little boy, she should just talk to him. It's like so hard for her to connect with her children, same with Don. They practically have to forced into the worst situation, like being violent with each other, before they open up with the kids and one another.
I also thought there was some weird sexual tension with that priest and Peggy. In fact all the women seemed to be coming on to the priest but he seemed to be sending some signals to Peggy. That would be a scandalous storyline.
Oh and Sally Draper stole the episode, she is hilarious!
