Reading the plot description for this week's Mad Men, "The Gypsy and the Hobo," and it says that a former client returns to Sterling Cooper and Betty takes the kids on a trip. I'm assuming the trip is without Don/Dick. I wonder if she'll return.

Here's a sneak peek of the episode, and I think it shows the client in question. Not sure who the gypsy refers to or the hobo (perhaps the one Dick met as a kid?).
