The lunchbox Willow uses to hold tools in the morgue is Scooby-doo themed.
Oz's werewolf form, last seen in Phases (1998), is radically changed. Then, the werewolf is portrayed as a gray bipedal creature with a wolf-like head. Now, his fur is a darker brown, he moves largely on four legs, and he has a human-like, hairless face with no muzzle. Among the production staff, the new makeup was referred to as the 'Gay Possum'.
Giles explains that demon dimensions are places of brutal torment in which time moves extremely fast. Over the time between being sent to Hell and brought back, Angel has experienced 100 years of torment.
Xander previously jokingly referred to Buffy as a Watcher's Pet (a play on the phrase Teacher's Pet) when Giles snapped at Xander for his sarcasm while agreeing with Buffy's sarcastic comment a few minutes later. A variation happens in this episode, when Xander falls asleep and gets severely reprimanded by Giles, yet when Buffy falls asleep while watching Oz the next night, Giles gently wakes her up and doesn't chastise her for the same action.
Scott advising Buffy before she visits Mr. Platt was cut:
- Scott: "Stable. Okay. Topics to avoid. The little men that live in your teeth...your compulsion to paint circus clowns..."
- Buffy: "But if God keeps telling me to kill - it just seems snotty not to, you know?"
