After Fred awakens Charlotte from her "micro-nap", they discuss the jokes he has written for her speech. During the conversation, Fred puts his laptop on Charlotte's desk. As the scene ends, Fred leaves the room without the laptop in his hands (as he was directed to make changes to the speech, he would need his laptop for that work).
In the first exterior shot of the Secretary's plane on the way to Sweden an airborne 747 is shown. The exterior scene upon exiting the plane shows what is likely a 767 or 777. The distinctive hump of a 747 is gone.
It's stated that Charlotte Field is the youngest US Secretary of State ever. Though her age isn't directly stated, it is implied she is 41, as Fred states she was 16 when she babysat him 25 years prior. Richard Rush served in 1817 when he was 37, and Edmund Randolph served in 1794 when he was 40.
President Chambers states he will endorse Charlotte if she decides to run for president, though it is a long-standing precedent for party leaders not to endorse a candidate until they have won the primary process.
