"Hi Faith" Buffy greeted her sister Slayer.
"Hey B. Any thing interesting going on?"
"Just more demons. New names, same destruction."
"The usual. I'm off to the dojo. I finally made Instructor's Assistant so they're gonna' have to start paying me."
"Lucky."
"When you got it, flaunt it."
"Oh, wait.. Xander and Dawn were talking, she thinks that you're 21, but Xander thinks your only 20. So which is it? Movie night rests on your answer, please be 20."
("Xander can't decide if you're 20 or 21. Movie selection rests on your answer, please be 20")
Faith laughs "What don't want to 'The Princess Bride' AGAIN? You're in luck, I'm still 19, so I get to pick."
