Cary-Hiroyuki Tagawa plays Tegoro, a suspect interviewed by Crockett and Tubbs. The same actor would be Don Johnson's boss a few years later in the series Nash Bridges (1996).
Air America was the cover name for the CIA-sponsored air service used in their southeast Asian intelligence missions, most famous for the rumors surrounding its involvement in the local drug smuggling trade in order to fund the Vietnam war. It was also referenced in Back in the World (1985).
The set for the escort service appears to be the same one used for the escort service in By Hooker by Crook (1987).
Final Trudy-centric episode of the series.
Near the end of the episode, Halliwell ties up Trudy and tells her that he's going to perform "falanga" on her, which he then describes as an old method of inflicting pain on someone by beating the soles of their bare feet (although Halliwell shocks Trudy through them). The other term for this is "bastinado", which was widely used in the American south during slavery by white slave owners and overseers on their black slaves, especially on women slaves with a higher market value. Reason for this was it was considered a "cleaner" type of abuse because it didn't leave visible injuries which would in turn lower the slave's aforementioned market value. This is particularly eye-opening because Halliwell was a white man inflicting bastinado on a black woman, and Trudy was traumatized afterward as she was crying uncontrollably in Crockett's arms, indicating how horrific bastinado, or falanga, is.
