Continuity mistake: When Angelus is spitting out Gage's blood, he goes from straight up to leaned over between cuts.
Continuity mistake: After Willow says that the student was killed by being opened up like an Oreo "except without the chocolaty cookie goodness," Buffy's hands go from together to apart instantly between cuts. She then puts her hands back together only for them to be apart again in the next shot.
Continuity mistake: When Buffy is talking to Cameron in his car near the start, the amount of light on Cameron's face coming through the windshield changes between cuts a few times. Sometimes the top is up over his eyes, sometimes it's down by his nose, etc. Also, depending on the angle, sometimes there's a purple glow on his face and sometimes not.
Continuity mistake: When Buffy and the guy are talking at the beach in the beginning, right before they hear a voice scream "Somebody help me!", the guy starts to turn to look at the tide. However, in the next shot, he's instantly facing Buffy again and then turns to face the tide a second time.
Continuity mistake: According to Giles in 'Revelations' there are 12 cemeteries in Sunnydale, but in 'Becoming Part 1', amongst others, Buffy agrees to meet someone (Angelus in this case) in 'the cemetery'. If there are 12 in the city, how would they know which one she means? (00:35:40)
Continuity mistake: Drusilla kills Kendra by cutting open her jugular artery and leaving her to bleed to death. When Buffy enters a while later, there is not a drop of blood anywhere. (00:41:40 - 00:42:45)
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. There is a cut to a shot of Buffy from behind showing a cop raising his gun, but he couldn't have come through the door without us seeing him in the last shot. (00:43:10)
Continuity mistake: The white outline drawn by the coroner does not match where Kendra's body fell after being killed by Drusilla.
Continuity mistake: When Joyce is being interviewed by the policemen at the house, you can see the number outside the house, but it says 163 instead of 1630, the number on which Buffy lives.
Continuity mistake: In "Becoming Part 2" At the end when Spike chokes Drusilla unconscious, he picks her up, one of her hands is resting on her stomach and the other is hanging to her side. It cuts to a shot of Spike looking at Angel and Buffy fighting then to Spike leaving with his back facing the camera. You can see that the hand resting on Drusilla's stomach moved to Spike's shoulder.
Continuity mistake: Lily's boyfriend is taken into an alternate dimension, where time moves quicker than ours, and is kept there until he is an old man. But when Buffy finds him, she realizes who he is because of his tattoo - which has not faded or aged in any way. (00:23:20 - 00:34:30)
Continuity mistake: In the episode 'Anne' when the latest people to be brought into hell are lined up with a demon talking to them, there are 3 or 4 people standing between Buffy and Lily. When the demon asks them all in turn 'Who are you?' we see him asking Lily and after that the shot rests on Buffy, but in the background we only hear him ask one more person before he gets to Buffy. (00:35:50)
Continuity mistake: In the scene where Buffy has just finished fighting the demons, she begins climbing up chains and if you look at her shoes, they continue to change until she reaches the ground above the chains and runs off. (00:40:30)
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.
