Continuity mistake: When Sam says she'll go to the inauguration, the invitation lies between both tables but a shot later it is just on one table.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
