The episode appears to answer a long-running question of the original Quantum Leap (1989), mainly what people remember of the Waiting Room and AI in the future, during the time they switched bodies with Sam, after they return to their original time. Magic seems to answer this question in that he remembered nothing and recalls simply "blacking out", but for years he had dreams of Sam Beckett's face.
The event Herbert "Magic" Williams (Ernie Hudson) describes in his conversation with Ian (Mason Alexander Park) is from The Leap Home: Part 2 (Vietnam) - April 7, 1970 (1990).
Dr. Ben Song asks, "You have a gun?", to which Jake answers, "Yeah, what do you suggest we use, harsh language?" A similar line is uttered by Private Frost in Aliens (1986) when Sergeant Apone orders the marines to unload their weapons near the fusion generator.
Despite his story of being 'jumped into' by Sam in the original show, Quantum Leap (1989) is one of the few TV shows Ernie Hudson did not appear on over the past few decades.
