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)

Continuity mistake: In 'Becoming, part 1' as Buffy kneels over Kendra's corpse you can see the door over her shoulder, it stays closed all the time.

School Hard - S2-E3

School Hard - S2-E3
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.

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.
Answer: She has superpowers, ergo fast movement. The reason she outruns him so easily in "Touched" is that she stops trying to actually fight him and just dodges instead.
