- Critical Research Failure: Referring to the Chumash, Spike says "You [i.e. white Americans] exterminated his race." This is technically incorrect, as there are still several thousand Chumash living in and around the California area today.
- Designated Villain: Buffy briefly has some guilt over having to fight a spirit with a very justified grudge, but the episode quickly plows past it. Of course, as Spike points out, what said spirit wants is to murder everyone as revenge for the massacre of his own people, so short of letting themselves be brutally slaughtered, there's not really anything that can be done about it.
- Hilarious in Hindsight: A Joss Whedon-Drew Goddard project featuring murderous scalp-happy Native American Spirits, Native American with ceremonial Native American knives used to kill a victim which slits a victim's throat, slices off their left ear and then starts to (before cutting off-screen) scalp the deceased victim.
