Hands and Knees

Joan Harris (Christina Hendricks) informs Roger Sterling (John Slattery) that she is pregnant, and that he is the father because Greg has been away for weeks.

They make dinner plans and Lane asks Don Draper (Jon Hamm) to come to defuse the tension between them.

Two men from the Department of Defense come to the Francis home to question Betty (January Jones) since North American Aviation has requested verification of Don's application form.

In a phone call made after they've left, Betty tells Don about the meeting, which instantly throws him into a panic.

He learns that his secretary, Megan (Jessica Paré), filled out his application form and he unknowingly signed it, unaware that it contained lies that could potentially compromise his identity.

After returning home with Faye Miller, Don mistakes two men for agents of the Department of Defense, and is struck with a panic attack.

In the next meeting of the partners, Pete fabricates a story to explain why North American Aviation is leaving SCDP, and accepts the blame for it.

Joan goes through the "status of accounts" and Roger gives a thumbs up when Lucky Strike is called, indicating his intention to hide the loss from the other partners.
