Come, Let Us Reason Together - S7-E13
Continuity mistake: By this episode, the restaurant windows have been displayed as Caroline's restaurant (replacing Nellie's). Although most scenes here correctly display Caroline's, one scene that starts from the outside with the horses riding by, the windows still display Nellie's (happens about 3 times this episode - the last time is shown just before Nellie and Percival are laughing on the bed).
