The main character in this episode of "Mad Men" is the IBM computer. A symbol of all the changes happening in America and in the ad agency, its installation disrupts the office. Everyone, from Roger and Pete to Don and Peggy, seem to be in the shadows, feeling very vulnerable. The swagger is gone, perhaps forever. The humans have lost the control they once assumed they had.
Roger's daughter Margaret joins a commune, adopting the name "Marigold." This is not what he envisioned for her.
Cocky Pete comes down a few notches when George tells him that his soon to be former father in law (Trudy's dad) has had a heart attack.
Don is ignored as he re-enters the office. This is the new age of the computer and he is a creature from the past. He reports to Peggy. Of course, he can't handle that, snatches a bottle of booze from Roger's office and downs the whole thing. The office's recovering alcholic Freddie gives Don a talking to. But whether Don can truly engineer an internal paradigm shift, including sobriety, is up in the air. He could just as easily go out the window.
Peggy who should be feeling at the top of her game takes refuge in gossip with the office aging sex object Joan. Peggy has been around long enough to know that she should be presenting an image of power. Yet, the pieces haven't come together in her journey from blue collar ethnic Catholic Brooklyn and the big time in advertising. Will she emerge as a force field? One wonders if she has the inner whatever to put that together.
Meanwhile, the computer will reconfigure everything from new business development to how the creatives go about producing the deliverables for the clients. It will be interesting who will get that and who will resist it. If Don gets it, his career path is back on an upward trajectory.
