In a closing scene of the Season 2 Finale, "Mommy's Bosses," Dr. Kevin Burkhoff, played by Jeffrey Combs is shown preparing to inject himself with a dose of "promycin," appearing as a fluorescent yellow/green serum. This echoes a scene from Re-Animator (1985), where Herbert West, also played by Jeffrey Combs, is caught injecting himself with a similar-looking substance to keep his "mind sharp."
