While Ozai and Zuko are talking just before the Agni Kai, Azula's hands change positions between shots. When the camera is behind her, her hands are behind her back, left hand holding right wrist. When the camera shows her from the front, her hands are close together, just below the brooch on her waist sash. When the camera moves behind her again, her hands are once again behind her back, left hand gripping right wrist.
