Continuity mistake: In 'Gone', when invisible Buffy is typing on the social worker's keyboard the letter 'B' is pressed several times. When she prints what she's been typing seconds later it's revealed to be "All work and no play make Doris a dull girl", a phrase which contains no 'B's. (00:21:10)Shay
Continuity mistake: In the alleyway scene after the real Buffy kills all the Hellions (biker demons) and runs off, one of the Hellions can be seen getting up behind Xander. We then see a closeup shot of the Hellion opening its eyes while still lying on the ground and then they stand up and sneak up behind Xander again.THGhost
Continuity mistake: When Buffy is singing "Something to Sing About", she sings the verse beginning 'All the joy life sends, family and friends', and we see that Anya and Tara are stood in the background, about 3 metres apart from each other. However, for one shot, they appear less than 1 metre from each other. (00:42:05)
Continuity mistake: In the musical episode, 'Once More, With Feeling', when Buffy is singing her song in the Bronze, 'Something to Sing About', she breaks a pool cue over a demon's head. She holds the remains in her right hand and clubs another demon in the face with it, then the camera cuts to another angle and it's in her left hand when she stabs the next demon with it.
Continuity mistake: In the beginning of the show, Buffy has two necklaces on, one long and one short. However, when Buffy, as Joan, is telling everyone her plan to get away from the vampires, she only has the short necklace on. Then when she is outside, running from Spike, as Randy, both necklaces are back on.
Continuity mistake: When Spike is looking out the window at the demons rampaging in the street outside Buffy's house, Dawn can be standing behind him with her hair trailing down below her breasts. In the next shot, when Spike pulls her away from the window, her hair is pulled back behind her shoulders despite her not having moved. (00:53:10)
