Continuity mistake: In the last scene in the train car before President Grant walks in, two bottles are in the middle of the table (labels facing away from one another) with four glasses behind them. When the President enters and walks towards the table, both bottles are now placed further back (labels are now facing to the front) with the four glass and an ashtray in front of the bottles. After the President refuses a drink of wine, the table is back to the original setup - labels faces away one another and glasses are behind the bottles; the ashtray is no longer there.
Continuity mistake: In the scene before the second freeze frame appears, West is wearing a white shirt with a black neckerchief and blue corduroy jacket. In the close-up of West being handcuffed, he is wearing a blue vest and a different non-corduroy blue jacket. For the rest of the episode, West wears the original white shirt with black neckerchief and blue corduroy jacket.
