Out Of Mind, Out Of Sight - S1-E11
Audio problem: When Cordelia is tied to the chair at the end of the episode from a side view you can see her mouth 'Marcie' but can't hear it and in the front shot she says 'Marcie' again.
Out Of Mind, Out Of Sight - S1-E11
Audio problem: When the invisible girl writes "Listen" on the chalkboard, the chalk sound effects don't match the writing for the last few strokes. (They're about a half-second too "early.").
Out Of Mind, Out Of Sight - S1-E11
Audio problem: When Cordy and Buffy are talking and Cordy says "Well it beats being alone all by yourself, " pay attention. It's clear that part of the line was dubbed in, as there is a very hard cut between the words "Well" and "It."
Out Of Mind, Out Of Sight - S1-E11
Audio problem: When Cordelia wins May Queen, the clapping sound effect doesn't match the students clapping in the slightest. It's far too loud considering it's a small group outside, and continues on for about two seconds after the students clapping.
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.
