Original sentence: Whether or not Buffy's second death called another Slayer is in fact known, because Faith was still in Sunnydale at the time and Buffy and Faith would've had to be dead at the same time, only calling one new Slayer as confirmed by Joss Whedon, but what is clear is that her second resurrection for some reason caused an imbalance in the Slayer line
Edited sentence: Buffy's second death did not result in another slayer being called because of Faith - a new slayer would not be called until her death, but however, Buffy's second resurrection for some reason caused an imbalance in the Slayer line
