Continuity mistake: When Buffy is fighting the vampires at the end of the episode, she grabs a tennis racket and smashes the brunette vampire over the head. She falls over the back of the couch and we hear the thud of her landing, however in the wide shot of the couch the vampire has just started to go over the back.
Visible crew/equipment: When Buffy and Xander are doing some research, check the left side of the screen in a wide shot, when Xander asks "how far back do the disappearances go?" You may need to turn the brightness up, but there's a boom mike bobbing around. (00:34:25)
