Danielle says that she used to watch Buffy the Vampire Slayer (1997) with Jenny, who wanted Spike and Buffy to hook up. Both Buffy the Vampire Slayer (1997) and The Twilight Zone (2002) aired on UPN from 2002 to 2003.
Unusually, the opening narration doesn't contain the words 'the Twilight Zone'.
This episode is a reiteration of a short story from the nineties, which was likely a reiterating in itself.
