Becca's excited for her upcoming presentation to the energy task force her dad has appointed her to; she's prepared a voluminous binder of background notes. She wants to bounce some thoughts off Marshall, but he's swamped. She walks with him through the basements of the White House where he shows her a secret lair: a private office for Reba Cadbury, a staffer who doesn't exist. It's the only place he can get away and think, he tells Becca.
At the task force meeting, Becca is met by the chairman, Senator Faxler. Given that she's the President's daughter, he's very ingratiating, but ultimately demeans Becca and shows her out of the meeting. Becca consults her dad, who tells her that it's natural for the task force to be skeptical. He encourages Becca to break through whatever roadblock Senator Faxler has set up for her. Becca springs into action, sending the senator policy suggestions as Reba Cadbury; she even has Xander make a fake Wikipedia entry for her. Faxler likes Reba's ideas and wants to meet her for lunch. Marshall catches wind of the scheme and tells Becca she's playing with fire. Becca insists it'll blow over.

But before she can break the news to him, Marshall interrupts to declare that Reba has tragically died in a car accident.
Skip trudges through the paper - but gets it done. Emily's thrilled; she's been able to get Skip to finish something that his father's been after him for years to complete. She waves the finished paper in Dale's face. Skip arrives but he doesn't share Emily's enthusiasm. He's afraid now that he's a college graduate, he'll have to start acting like an adult.
