(Buffy's room)

RILEY: (between kisses) We're not expecting anyone, are we?

BUFFY: Willow said she was going to be at the science library all night.

RILEY: Is that right?

(Willow barges in)

BUFFY: Uh, apparently not.

WILLOW: (worried) We got trouble.

BUFFY: (serious) What is it?

WILLOW: I was in the rec room. It came through the window.

RILEY: Vampire?

WILLOW: Vampires don't breathe fire.

(they head down to the rec room)

RILEY: I should call for backup.

BUFFY: No time. We have to make this fast. I have better things to do tonight than kill.

(Buffy opens the door to find: a surpise 19th birthday party)

Everybody: SURPRISE!!!

WILLOW: (smiling) Guess you won't be killing anything tonight, after all.

BUFFY: (sly grin) Don't be so sure.
