In Buffy the Vampire Slayer after Buffy dies the second time in the episode The Gift why isn't another slayer awakened?

Answer 1

Usually, when a slayer dies, the next one is activated. In Buffy's case, this was Kendra. Kendra was killed, hence, Faith was activated. The activation of the next slayer only happens once in Buffy's case. Technically, Buffy had already died once before 'The Gift'. Her replacement had already been activated and killed, so there wouldn't be another when she died the second time. If you want to get REALLY technical, Buffy died 3 times on the show. Although it was an alternate dimension, she was killed in 'The Wish'. So REALLY technically, there is an alternate dimension Kendra, presumably still alive, thus no Faith.
