Kennedy gets killed

Amy looked away from Kennedy for a moment and then cried out, "Look out, Kennedy!"

But before Kennedy could respond, Darla fired a bullet into the back of her skull.

Then Darla fired a bullet into Amy's forehead.

Buffy tried to rush forward to disarm her, but Drusilla tripped her and by the time Buffy could recover...

Darla had time to turn and fired a bullet into her chest.

"Well, that was pretty anticlimatic, Grandmother," said Drusilla.

"Well, like your boyfriend likes to say, it's not how you fight but who gets to walk away from it that really matters," said Darla. "Had the two of us played fair, we would have either been staked or else turned into rats. And I for one hate the taste of cheese."

"Still, it would have been a lot more fun to win the old-fashioned way," said Drusilla. "Anyway, what about Spike?"

"What about him?" asked Darla.

"How are we going to turn him back now that the Witch's Daughter is dead?" asked Drusilla.

"Damn it, Drusilla," said Darla. "We're living on the Hellmouth, remember? Anyway, there is more than one magic-user in Sunnydale and I'm quite sure that at least one of them will have enough ability to reverse the spell that was put on Spike. Now if you don't mind, I have to go tell the Master about this. He's just going to love the fact that I managed to kill not just one but two Slayers. Hell, I might even get a promotion out of this."
