The Buffy and Angel Trivia Guide // One down… one gone

In the episode What’s My Line (Part One), Spike’s vampires steal the DuLac cross from a tomb in the graveyard. Buffy stakes one of the two vampires and then watches Dalton (the other vamp) running away for his life, saying, “One down, one… gone.”
In Earshot, Buffy fights two telepathic demons at the beginning of the episode. She kills one of the two, and then says, “One down, one… gone” again.
