Nightmares - S1-E10
Continuity mistake: At the beginning of the episode when Buffy and Willow stop at Buffy's locker, in the first shot, Willow has her backpack strap on her shoulder and takes it off. It then cuts to another angle and Willow's backpack strap is back on her shoulder, and she takes it off a second time.

Continuity mistake: In the beginning dream sequence, when Buffy is surprised by the Master and backs up into the wall, watch her two pigtails. As the scene cuts back and forth between Buffy and the Master, her pigtails move from behind her shoulders to in front of her shoulders and back several times. First they're both behind her shoulders, then only one is behind, then both are in front, then one moves back behind again, etc. Obviously multiple different takes were cut together in editing.

Continuity mistake: Buffy's history teacher is not the same person from episode 1 or 9, originally a woman, the teacher is now a man. Cordelia also notes Buffy doesn't know where the class is due to ditching, but we saw Buffy in her history class with Cordelia in The Puppet Show. How could Buffy not know where her class is only 1-2 weeks later?





Chosen answer: From what we see in the series, certain girls are identifiable as potential Slayers - Kendra clearly fell into this category. The identification method is presumably mystical in nature, but the Watchers' Council are pretty effective at that sort of thing, so they're quite good at tracking down the potentials ahead of time. Not perfect, though - it does appear that Buffy herself may have slipped through the net - certainly she had no inkling of what she was until she'd already taken on the role of Slayer. It is possible, however, that this was actually cultural - an American family would hardly be likely to turn over their daughter to some strange man for 'training', so the Watchers might have chosen to keep an eye on her covertly, whereas some other cultures (like Kendra's Jamaican parents) might be more willing to believe.
