Several times, the length of David's tie changes between indoor and outdoor scenes in the same sequence. Example: Episode 8 opens with David walking back to Bamfylde early in the morning. His tie ends well above his belt. When David arrives at his house and talks with Molyneux, David's tie extends below his belt. From there, David goes outdoors to meet Algy and Brigadier Cooper, and his tie is once again short.
