19. Sibling rivalry, Part II
Fight! Fight! Fight!

Buffy's bedroom flew open, revealing a very pissed-off Dawn.

"OK, sis, that's it. I'm throwing down! Welcome to Summerslam!"

And it was on, with the kicking and the punching and the scratching and... you know what chick fights look like. It took them an hour to realise they were evenly matched (possibly because of the whole made-from-the-same-blood deal) and call a truce, according to which Buffy got Spike during daylight and Dawn at night. Also, Spike would have to nail pictures of sad puppies to his ceiling to ensure Dawn was never perfectly happy. (Buffy preferred it on top anyway.)

Author's note: TBC. And thanks to Axel for suggesting "Summerslam".
