After Lizzie has been sent home from school for some sleep, as her mom and dad walk her over to the couch, Lizzie is not wearing a bag. But as they all sit down, now Lizzie has her small bag hanging over her left shoulder.
Near the end of the episode, when Lizzie, Gordo and Miranda are walking down the street, Lizzie begins to say how she could concentrate on helping stray dogs. However in one shot of Miranda, while we still hear Lizzie talking, Lizzie can be seen in the shot with her mouth closed and smiling.
