The "gangs" depicted in this episode are fictitious. However, some real "Red Scorpions" are based in Canada. Like their real-life counterparts, the Scorpions (of this story) include members from various multicultural backgrounds who may be identified by a tattoo on the hand or wrist.
The opening theme for this episode is slightly slower and has an extra guitar in the background.
Beside the change in music mentioned in the prior item (addition of the distinctive 70's waka guitar sound) the opening credits change again mainly the clothes of Barnaby, Betty, and JR.
Even the gang members and their girlfriends drive Ford vehicles. Mustangs, Falcons and Econoline vans.
