The Buffalo Bill character returns from the first episode, "Smithereens."
The four police officers at the end of the episode are all wearing CHP (California Highway Patrol) "shorty" helmets, made famous by the show CHiPs. Even though they were not motorcycle officers, many departments required their traffic officers to wear helmets for added safety during pursuits. This practice still takes place with some agencies today.
Sam and Abbey are racing to Royce Industries, Sam on his motorcycle and Abbey in her jeep. Sam gets pulled over by a cop and spends several minutes playing invisible hide-and-seek with him, while Abbey drives by. Yet somehow, when Abbey gets to Royce Industries, Sam is already there. She's surprised to see him, but he would have had to pass her to get there.
The "stabilizer" watch Sam is given is actually a Heuer Chronosplit model introduced in 1975, with brand and model names removed. The Chronosplit was one of the earliest digital watches with an liquid crystal display but also kept an LED display. The LED was used for stopwatch functions, necessary because the early LCDs had slow response times. The "gold contacts" that Sam had to keep against his skin were actually the covers for the two batteries the watch needed.
