He advises putting Harry Crane on the account to come up with other ideas.
Pete's mother and servant Manolo are escorted up to his office, just as Peggy exits. While Pete asks to speak with Manolo privately, Peggy speaks with Pete's mother who seems to have her confused with Trudy. Dorothy commends 'Trudy' for reuniting with her son, if for no other reason than for the love of the child the two have.

At her home, Betty Draper confronts Sally over a prospective school trip into the city, forbidding her from staying in a hotel with boys.

When Don introduces himself, Mitchell retreats to another room and Megan confesses that he has been drafted and is attempting to flee to Canada. Megan is torn between helping him and going behind Sylvia and Arnold's backs -- Don says it's not their problem, and that Mitchell can't spend his entire life on the run.
Peggy, Ted, and Pete are several drinks in at a restaurant that evening.

Ted assures him that flying is perfectly safe, but is taken aback when Pete confesses that his father was killed in a plane crash. Ted excuses himself to call home, leaving Pete and Peggy alone to talk about him. Pete surmises that Peggy has feelings for Ted, before unhappily lamenting that the two have been on opposite trajectories -- Peggy is 'important' and Pete feels that everyone pities him. Peggy claims she doesn't because, as Pete tells her, 'you really know me.' The two share a quiet moment before Peggy relates the awkward conversation she had with Pete's mother. As Ted returns, Pete jokes that he has never been less afraid of flying in his life after learning of his mother's sexual escapades.

Don takes Arnold to a bar for a drink, where he tells Don he never knew Mitchell left school in Paris and wishes he had stayed. Don suggests that perhaps, as a successful surgeon, Arnold may know someone who can help get his son removed from the 1-A classification. Arnold is torn between not wanting his son to go to war and realizing it is a necessity for citizenship in the country, admitting that his own service helped pay for his medical training.

She is upset with her husband about no-showing a family dinner to hang out with work friends, saying he works too much and even during his downtime his mind is on work-related things.

Sally and Julie have a slumber party and read off a list of things they like about Mitchell. Megan interrupts the hushed laughter and tells them lights out. Meanwhile, Peggy finds a trail of blood in her apartment leading under the couch, presumably from the rat. She awakens Stan, calling him in the middle of the night.

That morning at Don and Megan's apartment, Megan is in a hurry to get Sally and Julie ready to leave. She is late for work and sends Sally to get washed up. At the office, Ted confronts Don about the Chevy meeting the night before. Don says he felt desperate, that he didn't mean to step on Ted's business endeavor, only thinking that GM had clout in Washington that could help Mitchell. Ted says he may have sway to get Mitchell into flight school if Don will relent in his power struggle in the company. Don agrees. Don calls Sylvia to convey the news, and she is overcome with gratitude. She tearfully thanks him for helping her family, even after she had broken off their affair.
Bob meets Pete in his office to go to lunch. Pete is livid at Bob for introducing Manolo into his mother's life. Bob pours drinks and assures Pete that despite what his mother may have told him, Manolo doesn't swing that way. He insists that Manolo is simply caring for his mother, and that she may have misinterpreted taking care of her every need as feelings of love. As he tells him this, Bob smiles and moves his knee to touch Pete's, as Pete looks shocked. He tells Bob that he will give Manolo one month's pay and that his services are no longer needed. Bob feigns a smile, but leaves clearly upset.
