"Ok, so X equals?" Willow looked towards Buffy.

"Umm?" Buffy had her face buried in a book while she scribbled on a blank piece of paper. "Seven?"

"Yes." Willow said excitedly.

"Yes? I actually got it right?" Buffy asked. "Yes!" she yelled.

"Shhh." The librarian shushed them. He was a middle-aged man, dressed in a brown Tweed suit. His glasses sat low on the bridge of his nose and he always had that nose in one book or another.

The girls had been in the library during their free period studying for their Algebra test. Both girls were pretty good at the subject, but they could always use a little extra practice.

Suddenly the library doors swung open and in walked a tall boy with white hair.

"Uncle Rups?" he yelled, totally ignoring the scowls he was getting from everyone in the library.

"William? How many times do I have to tell you that this is a quiet place?" the librarian said hurrying through the stacks to greet his visitor.

"Yea well when do I ever listen to you?" the boy answered leaning on the counter.

The librarian lead the boy into a back office, where their conversation was out of hearing range of Buffy.

"Who's that?" she asked Willow looking back to where the two had disappeared.

"Oh that's another new kid. I think his name is William Giles. It's the librarian's nephew. Came all the way from London." Willow replied all in one breathe.

"Wow," Buffy replied still staring back towards the doors.

"Yea, I heard that he got kicked out of his school because he was in a gang, and his grandmother couldn't control him anymore so she sent him to live with his uncle, which I guess would be Mr. Giles, the librarian." Willow looked at the watch, strapped to her wrist, and began putting her books into her book bag. "Bell's gonna ring soon. You might want to clean up."

"Yea I guess so." Buffy said finally turning back around and stuffing her books into her book bag. The bell sounded through the library and all the kids got up and made there way to the door. Buffy and Willow followed making it almost to the door before Buffy realized that she forgot her notebook. She looked back; glad to see that it was still sitting on the table. She ran back, grabbed her notebook, and turned quickly, slamming right into Spike. Buffy fell to the ground, her books went everywhere.

"Sorry," Spike said offering his hand to the girl laying on the floor in front of him.

Buffy looked up at the boy, and slowly grabbed his hand. He pulled her up, until she was standing on her own two feet.

"Sorry," Spike repeated himself. "I'm in a bit of a rush. Guess I wasn't looking where I was going." He bent down and grabbed her books.

"Thanks." She said, taking them from him.

"I'm Spike." He offered out his hand again. 'She's beautiful.' He thought 'Maybe a bit young though.'

"Buffy," Buffy replied taking his hand and shaking it. "I better get going. Class." She began to walk away when he grabbed her elbow. She turned to look at him. 'God his eyes are beautiful. And that body.'

"Would you like to show me around town? Tonight maybe?" Spike asked going out on a limb. "I heard something about this club called 'The Bronze'? Any good?"

"Yea. It's about the only place in town that's worth going to." Buffy said. 'I can't believe this kid.this senior is asking me out!' "Around 7?"

"Sounds great. Where do you live?"

Buffy scribbled down her number and address on a piece of paper and gave it to Spike. "I'm gonna be late."

"Oh don't worry." Spike said coolly. "Uncle Rups?" he called out, his voice echoeing through the empty library.

"William, that's Mr. Giles while we are in school. Like it or not you will have to show me some respect." Mr. Giles said as he made his way out of the back office.

"Sorry," Spike said with a roll of his eyes. "Can the girl get a late pass? I kept her with my questions."

"Uh, sure." Mr. Giles quickly wrote Buffy a pass.

"Thanks." She said taking the piece of paper. "I'll see you tonight, Spike."

"Tonight, luv."
