Tabula Rasa - S6-E8
Continuity mistake: When Buffy and Dawn are discussing Buffy's new name choice Dawn's hair changes repeatedly between shots. First it's over her shoulders, then behind, she has a clip in one shot, then she doesn't.
Tabula Rasa - S6-E8
Continuity mistake: In 'Tabula Rasa' when the loan shark's henchmen throw a stake at Spike at the start it flies over his head and hits a tree. But, if you compare the angle they approach from with the relative positions of Spike and the tree you can see it would have had to do a 90 degree turn in mid air to fly over his head before hitting the tree. (00:01:00)
Tabula Rasa - S6-E8
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.
Tabula Rasa - S6-E8
Continuity mistake: When Anya is standing on the table, wide shots show her holding the spellbook in front of her, but closeups show her holding it tight to her chest. (00:30:30)
Tabula Rasa - S6-E8
Continuity mistake: When Buffy and Spike (as Joan and Randy) are fighting Bro'os vampires, Buffy kicks down a post box to stake one of them. The pole supporting the post box breaks away at a jagged angle. But when she uses it to stake one of the vampires the end that she uses has suddenly changed to the traditional triangular point, only to return to its original jagged angle immediately afterwards. The shot of her staking the vampire is not a side angle of some uneven ends. Watch as she backs away from the vampire after he's been staked, it is a fully triangular point.
Tabula Rasa - S6-E8
Continuity mistake: When the gang is in the Magic Box and they pass out, we see Buffy fall on the floor at the top of the stairs, but in the next shot she has moved and is now lying on the steps.
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.
