First some things to clear up: Buffy is 17 here, and this takes place somewhere in season 1 or 2, so Booth is just single then ;P
Also I hope I keep the characters as much in chararacter as I can (I tried) and hope I get the scientist's stuff right, cause I'm not one myself XP
Hope you enjoy and comment :D
The Jeffersonian Institute was just as always packed with scientists, who would work all day on the most extraordinarily cases. Especially the ones who were busy working on solving another murder.
The body of a 35 year old woman was found in a bus shelter, which meant that the colleagues of Temperance Brennan were working on the evidence that she collected earlier with her partner; Seeley Booth.
Angela decided that Hodgins was working way too much, and she took her chance to go and have a chat with him. She was greeted by him, leaning over some earth samples, his eyes twinkling happily as soon as he saw her.
Hodgins walked over to her, and she handed him some papers about the case they were working on. "How are things going over here?" she asked him raising an eyebrow.
"So far, I haven't found any abnormal soils in the earth, but it's going good, you?" He said as he browsed through the papers.
"I've made a sketch of the victim, and I'm going give it to Brennan, but I thought I'd stop by here first," She smiled in that cute way, that made every guy swoon at the Jeffersonian.
Hodgins was just about to say something when they were interrupted by footsteps, "Excuse me?"
They both turned around to find a young blonde girl standing in the door opening, dressed in a yellow and red cheerleading outfit.
"I'm sorry to bother you, but could you tell me where mister Booth is?" She looked hopefully at the two.
"Of course sweety, can I ask what is it you need him for?" Angela asked curiously walking over to her.
The girl suddenly reached out for Angela's hand, introducing herself, "I'm Buffy Summers, mister Booth's babysitter."
Angela shook Buffy's hand and grinned widely, looking back at Hodgins who had to hold back a chuckle.
"I-I mean, I'm not his babysitter…" Buffy rattled, "Well, he has a son and -"
"We understand," Angela said quickly, not wanting to make the girl uncomfortable. "I'm Angela and this is Hodgins."
She pointed at herself and then at Hodgins, thinking it would make Buffy at ease if they introduced themselves.
"We'll take you to Booth, no problem," Hodgins showed the women the door, as if he was waiting for them to go first.
"Thank you," Buffy said happily walking out the door, followed by Angela whispering to Hodgins, "Is it just me, or does she look rather young and cute, instead of experienced?"
"I'm already looking forward to his explanation," Hodgins agreed.
"Bones, don't worry, we'll catch the killer in no time," Booth said confident.
They were in his office, him sitting in his chair, legs on the bureau, and her sitting in the chair across him.
"Angela told me that she will have the sketch done as soon as possible," Brennan stated.
"And I have it," they looked at the door, to find Angela, Hodgins and Buffy walk in.
Brennan instantly stood up and Angela handed the sketch to her, while closely observing Booth's expression, wish had turned from casual to nervous.
Booth lifted his legs from his bureau and also stood up, "Buffy, I'm sorry to call you so sudden."
Brennan turned her gaze to the young girl in her cheerleading outfit, she wondered who she was.
"It's no problem," Buffy said. "I was just on my way home from cheerleading practice, my sister asked me to coach."
She smiled and tugged at the skirt, hoping he didn't think of her as just some dumb schoolgirl.
Her mother told her that it would be financially good if Buffy looked for a job, and babysitting paid off pretty well, so she wasn't planning on loosing it.
Booth laughed, did she expect him to mind her clothing only because he's an FBI agent? If anything Booth would say that it looked rather good on her, and she should wear it all the time.
But of course he wouldn't, because maybe she'd think that he was hitting on her or something, he was already aware Angela and Hodgins were thinking it.
Booth reached in his pocket and pulled out some keys, "Here you go, these are the keys to my place, could you pick up Parker from school please? I thought I would be back in time but then there wasn't some dead body found."
Buffy took the keys, she was glad to know he trusted her enough to let her into his house with his child alone.
"Thanks, bye everyone!" Buffy waved at the remaining people in the office, and left with a swoop of blonde hair.
"Well, we all know what that was about," Hodgins said grinning as if he found out Booth's biggest secret.
Booth just opened his mouth to say something back, but was interrupted by Sweets walking in looking very excited, wish usually didn't mean much good.
"Who was that?" Sweets asked, clearly referring to Buffy.
"That's Booth's new babysitter" Hodgins answered, getting a glare from Booth.
"Why didn't you introduce me?" Brennan asked sounding offended.
"Well, isn't that clear?" Sweets said as Booth rubbed his temples, he hated it when Sweets used psychology on him.
"Listen, it's no big deal, I just hired her because she looked trustworthy -"
"She also looks hot," Angela interrupted him, giving a wink at Brennan even though she didn't have a clue what they were all talking about.
"Yeah, did you ask her to wear that uniform?" Sweets asked intrigued.
"What? No!" Booth tried to sound normal, but couldn't hide the light flush that covered his cheeks. "Don't you all have work to do?"
Everyone started to head for the door while mumbling and laughing, leaving only Brennan in the room.
"I don't understand what they mean," Brennan looked at Booth, thinking he'll explain it to her.
"That was nothing, they just like getting in other people's business," on moments like these Booth was relieved that she was as clueless as ever.
"Let's go and track down a killer!"
"No, I think I'll still have some time to patrol," Buffy said into the phone she was holding.
"Alright, so how is it over there, everything going well?" Willow asked.
Buffy looked around, she was sitting on the couch, and Parker was sitting in front of it on the floor, watching a children's movie.
"Yeah, he's a sweet kid," Buffy smiled, happy to know he didn't have pointy teeth.
Suddenly the door opened, and Parker stood up, yelling; "Dad's back!"
Indeed when Buffy turned around, she saw Booth throwing his coat on a chair, and take up Parker who managed to run over to him in seconds.
Buffy said that she'd see Willow later and hung up the phone, shifting her attention to her boss.
Booth laughed, holding Parker easily in his arms, "I hope he wasn't a troublemaker."
"No, not at all," the blonde girl said. "He's a delight, really."
She stood up and made her way over to the door, Booth reached in his pocket, and handed her the money she earned.
"Thanks," she smiled. "I guess I'll be back soon?"
"Probably," Booth answered as Parker started to kick his legs up and down, as a sign that his dad should let him go now.
"Bye, Buffy," the young boy grinned.
Buffy waved as she left the apartment, and Booth closed the door, still smiling like a moron.
"You know…" Buffy yelled at Willow and Xander, who were hidden behind a big, tombstone.
The vampire she'd been fighting just kicked at her, and she had to block the attack, he backed down and in one swift move she staked him.
The vampire screamed before disappearing into dust, and Buffy walked over to her friends, who stepped away from their hiding place.
"This may - come out - as a chock - " Buffy said between breaths, "But I think I like children more than vampires."
"Who doesn't?" Xander agreed.
"And the parents?" Willow asked, she had done some babysitting herself, and remembered that not every parent was as easy.
"Well, Parkers parents aren't together," Buffy said, as they all walked over the graveyard.
"And I only meet his father, who's a very nice guy."
She didn't notice that she was smiling, and Willow gave her an interesting look. "Is he by any chance also a handsome guy?"
"Well, I'd dare to say he's pretty hot," Buffy admitted.
"Wow, wow, wait a minute!" Xander suddenly stopped, and the girls almost bumped into him. "Are you saying you like some old dude?"
Buffy rolled her eyes, and crossed her arms, she could've guessed this would be his first reaction. "He's not old, and as I recall, didn't you almost mate with a giant bug?"
Willow chuckled and Xander couldn't come up with something clever to say back, so he just walked on in silence.
