Apparently, Buffy isn't the only Summers woman who is going to be "a fireman [sic] when the floods roll back."
ETA: beer_good_foamy reminded me that Joyce's threat to Spike, "You get the HELL away from my daughter!" (Rock on, Joyce!) could be seen as applicable to Buffy's actions in Chosen, if we consider the new Slayers as her metaphorical "offspring". (What's the plural for "childe"?)
Or, Kendra was her "daughter", Faith her "granddaughter", then Buffy and Faith got together and now the new Slayers have two mommies - which. ok, is kind of incest-y, but no worse than the Fanged Four, right?
And Willow is their midwife. Something like that.
