Continuity mistake: When Buffy's fighting Spike at the end of the episode, there are times when it's obvious that it's James Marsters' stunt double. Spike's hair is platinum blonde, slicked back, and all one length in the back, while the stunt double's hair is more brassy, spiked in the front, and layered in the back.
Revealing mistake: After Buffy has entered the wasp-filled school there's a shot of the others standing outside waiting for her. In the establishing long shot if you look closely you can see they used the same shot as earlier in the episode - Buffy is standing there with them. (00:34:10)Shay
Continuity mistake: When Anya leads Andrew away to their station in the school, she goes from having her right arm over his shoulders to having her left arm over her shoulders between shots. She is off camera for a second, but not long enough to move to the opposite side of him and change hands.Shay
Revealing mistake: When Buffy saves the man from being hit by a car, there is a very quick shot of the man standing in front of the car. In this shot, Buffy can seen on the left hand side of the screen running into the street to save him. But the shot then immediately cuts to Buffy who is suddenly still standing on the other side of the street with Lily and runs into the street to save him again.THGhost
