When Beth lights her cigarette she closes the cigarette case and puts it on the conference table as she offers one to Rob, and he at first refuses. Then she makes the reference to his past indiscretions, and the case is closed on the table. Then, when the PoV shifts to looking at Rob the cigarette case is now open on the table.
When Beth attends the meeting in Salt Lake City she is wearing glasses but she doesn't wear glasses at any time other than in the office.
