I'm confused about what the first Slayer's motives are. The first time we saw her was in "Helpless" and she tried to kill Buffy and her friends in their sleep. Does anyone know why? Next time we saw her was in "Intervention" where she was a guide to help Buffy. Then we saw her in Buffy's dream in "Get It Done" where she tackled Buffy down the stairs and told her "it's not enough. Was the first Slayer confused or evil? I mean, she goes from trying to kill Buffy, to helping her, to tackling her down the stairs.
