Character mistake: Higgins remembers having met the sisters "37 years ago this July", and shows a "theatre program from Blackpool the summer I completed my upper second at Sandhurst." Considering the episode is set in 1983, Higgins would have still been in military academy in WW2, which contradicts the plethora of experiences in North Africa and Burma. It's more likely that John Hillerman misspoke and it was meant to be "47 years ago", before the war. (00:37:30)
Character mistake: Magnum is holding a stinky pickled egg while he bickers with his friends in Rick's car. TC calls the store chain Magnum has been hired to protect "Day-N-Night" instead of "Day-N-Dark." (00:22:00)
