Chief Tyrol appears in this episode clean-shaven. He filmed his scenes for this episode weeks after the other scenes were shot. The producers felt a fake beard would not appear realistic so Tyrol appeared without the beard.
The character of Cally was never given a last name through the first two seasons of the show. It was even uncertain whether the name Cally was her first or last name. She is finally identified by the New Caprica Police as Cally Tyrol in this episode. Her maiden name, while not acknowledged on screen, has been established as Cally Henderson by the writers.
