Hey guys! Sorry for the delay in posting this chapter. I figured a holiday weekend (at least for those of us in the US) wouldn't be the best time to expect people to be reading stories on the Internet. But I hope those of you who celebrated had a good time!

As always, Bones (and Disney) isn't mine. Enjoy!

Booth was the first one up the next morning, waking just a little before nine. He remained under his bed's covers as he began looking around the room for Brennan. She was still asleep, snoring softly in her bed by the window. Booth climbed out of bed and headed for the bathroom, glancing over at her again. Brennan was lying on her back, her left arm curled against her body, her right stretched across the mattress. He noticed that the bathrobe she had fallen asleep in the night before had come apart as she turned in her sleep, her right breast now just barely covered by the fluffy white fabric. Booth sucked in a breath and walked into the bathroom.

After washing his face, shaving, and brushing his teeth, he opened the door to walk back into the bedroom. Brennan, who had obviously just woken up, lay slightly reclined against her pillows, rubbing her eyes.

"'Morning," Booth said softly.

"Booth…why am I wearing…" she asked, clutching her robe closed against her chest. She began to look nervous. "Did we…?"

"No!" he said immediately. "No, nothing like that. You fell asleep before you could change. I just pulled the covers over you."

"Oh," she nodded.

"You weren't uncomfortable, were you?" he asked.

"Oh, no. I actually don't wear pajamas often," she admitted, not really thinking about what she was saying. "I do sometimes, and I obviously wear underwear during my menstrual cycle, but I often prefer to wrap up in my sheets with only minimal clothing."

"Oh…" Booth mumbled, trying to will the mental image of a naked Brennan wrapped up in his sheets out of his head before he lost control of himself. "Really?"

"Yes," Brennan said. She pointed to the deep green tee lying on top of her suitcase. "Can you toss me my pajama top, please?"

"Sure," Booth said, reaching for the shirt. "Do you want some sort of…bottoms?"

She grinned. "I'm wearing panties, Booth."

"Right," he said, throwing her shirt to her. "Here."

After thanking him, she grabbed her shirt and ducked under the covers, slipping out of her robe and into her soft t-shirt. She felt his weight on the mattress as she changed and uncovered just her head to find him sitting next to where she lay. She pulled herself up until she was sitting on her knees and leaned towards him with a flirty smile. He shot her a charm smile of his own in return.

"Good morning," she said.

"Morning…" he mumbled just before her lips brushed against his.

She pulled away after the one, brief kiss, and his mouth instinctively followed her, expecting more. She noticed, smiled, and, before Booth could open his eyes, leaned into another kiss. As she began to pull out of their second kiss, Booth nipped her bottom lip with his teeth. She leaned back in, deciding to prolong the kiss, and opened her mouth against his. He slipped his tongue in to tease hers, and they each curled a hand around the other's cheek as they moved closer together to keep sharing good morning kisses.

After kissing her in front of the Hoover didn't go so well, Booth had begun to think that he would never get to kiss Brennan again. He certainly hadn't planned on trying, after their first three kisses hadn't gotten him anywhere, and he certainly didn't think that, if he were to talk himself into trying again, their fourth kiss would take place on the incline of a roller coaster. He never, in any of his scenarios, imagined that she would kiss him during a fireworks show while a cartoon cricket spoke about wishes coming true, and he really never expected their first time (well…second time) making out to occur in a Disney hotel room in little more than thin pajama shirts and underwear.

He knew he should break their kiss and find out how she was feeling about whatever was happening between them, but before he could do anything, she moaned as their tongues curled together, and Booth lost himself to the kiss again. He tugged at her hips, encouraging her to move to his lap. She sprang forward, and, never breaking their kiss, straddled him, settling onto his thighs.

Everything about her was soft, he thought. Her hair was soft against his fingers, her breasts were soft pressed against his chest, and her mouth and bare legs were soft against his. Overcome by the urge to discover if the milky skin along her neck was as soft as the rest of her, he broke their kiss and began trailing kisses across her neck. Brennan moaned and leaned her head back, and Booth instantly began focusing on the spot that made her moan.

"Oh, there, Booth," she sighed, curling her fingers into his hair. "Oh, that feels so good."

"That is so sexy," he mumbled against her skin.

"What is?" she asked.

"You moaning at me."

"You didn't like it when I moaned during my massage the other day," she pointed out.

"That's because you weren't moaning because of something I did to you," he said, kissing the spot on her neck between his words. "You moaning my name and telling me my mouth feels good on your skin is incredibly sexy, Bones."

"Yeah?" she asked softly.

"Yeah," he grinned before suckling on her neck again. She let out another moan but then began to push his head away. "What?"

"You've got to stop. You're going to give me a love bite if you keep going," she said.

"I'm not gonna give you a hickey!" he laughed. He brushed his lips over her neck one last time and said, "Though that'd be sexy, too."

"I'm serious," she said with a slight chuckle of her own.

They locked eyes for a moment, Booth brushing some hair out of her face. It was only a few seconds before Booth and Brennan returned to sharing passionate kisses to the lips. Still on his lap, one of Brennan's hands curled around his neck while her other rubbed his back beneath his white t-shirt. Booth was just inching his fingers up her side, underneath her green tee, to caress her bare breast when a knock at the door repelled them from one another. She looked at him quizzically.

"Breakfast," he said. "I ordered while you were still sleeping."

She nodded and climbed off him, pulling a pair of jeans over her white cotton panties as the hotel employee knocked again. He brought the food in, Brennan gave him a tip, and he left. Brennan turned to find herself face-to-face with Booth at the foot of his bed.

"It's good he interrupted us," she said. "We still have a case to solve."

"Yeah," Booth said, leaning to capture her lips in another kiss. He began maneuvering her back onto the bed as they kissed but pulled away the second her back hit the mattress.

"We have to work," they said simultaneously. They moved to the table and ate for a few minutes in silence, each of them stealing glances at the other.

"Booth," Brennan finally said. "Why did you kiss me on the roller coaster yesterday?"

"Why?" he asked in surprise.

"Well, it didn't really seem to be something you had planned to do, so I was just wondering why you did it," she explained.

"I don't know, Bones. You just…you had been complaining all morning, and when we started up that hill, I looked over at you, and you were…smiling and laughing and finally having fun. You looked beautiful," he said.

She thought about his answer for a moment. "Okay."

"Okay?" he asked, expecting more.

"Yes. I accept that explanation."

"Well why did you kiss me during the fireworks?" he asked.

"I told you," she said. "I was doing an experiment."

"About kissing me?" he asked. "Pretty sure we'd done that before, Bones."

"A good scientist would never draw conclusions after only one trial run," she said. "Yes, we've kissed before, but those kisses were clouded with everything from tequila to blackmail, so as a good scientist, I needed to successfully collect the same results from multiple attempts at the problem without any extraneous factors before I could accept my hypothesis as true."

"Problem?" he repeated with a cringe.

"In this case, I greatly enjoyed the kiss on the roller coaster, and I needed to see if that was a one-time reaction spurred on by the increased adrenaline from the effects of the ride and the spontaneity of the kiss or if the feelings would be duplicated if we were to kiss again."

"So…to get this straight…I kissed you because you're beautiful, and you kissed me because you were being a good scientist?" he asked.

"Yes," she said. Upon his dissatisfied look, she quickly added, "But also because the first kiss yesterday was unexpected but wonderful, and I very much wanted to do it again."

He smiled, thinking he had finally found the right opportunity to turn their partnership into something more. "So, Bones, what are we…" he began.

He was cut off by the ringing of her cell phone. She shot him and apologetic look and answered the call.

"Brennan," she said.

"Billie was pregnant," Mr. Nigel-Murray said.

"What?" Brennan asked, putting the phone on speaker so Booth could hear.

"I found fetal bones among the remains after I removed the flesh," her intern said.

"Are you sure?" Brennan asked.

"Positive," he said.

"Is there a problem?" Cam asked.

"We know she rode Space Mountain shortly before she died. It's explicitly stated that pregnant women shouldn't ride," Brennan explained.

"She was only five to seven weeks," Nigel-Murray said. "Perhaps she didn't know."

"Or she didn't care," Angela said, entering the room. Everyone on both ends of the call shot Angela, or the phone, in Booth and Brennan's case, a horrified look. "I'm just saying that when you think you're doing everything right and then a pregnancy test comes up positive, there's an adjustment period…denial, even. She might not have accepted it as a reality yet."

"I'm sending you photos of the fetal bones right now," Nigel-Murray said.

"Thanks," Brennan said. "Good work, Mr. Nigel-Murray."

"She was pregnant?" Booth asked as Brennan hung up. She nodded. "Guess it's time to pay another visit to our old buddy Vince."

Vince opened his dorm room door to find Booth and Brennan outside, about to knock.

"Oh, are you kidding me?" Vince sighed. "I thought you had cleared me?"

"We did, but some new evidence has come up," Brennan said.

"Were you aware that Billie was pregnant?" Booth asked.

Instantly, shock passed across Vince's face. After a moment, he simply said, "Well, it wasn't mine."

Brennan scoffed. "How do you know?"

"Billie and I never had sex," Vince said.

"You dated the girl for almost a year, and you never had sex?" Booth asked.

"I told you it was never serious," Vince said. "She said she was a virgin. She said she really liked me but just wanted to take it slow. I respected that. She was really pregnant?"

Brennan nodded. "A little less than six weeks."

Vince, with a hurt look on his face, did the math in his head. "Mid-January…winter break…I wasn't even in the state then," he said. He sighed. "I guess this explains why she suddenly stopped talking to me, huh?"

"I'm sorry," Booth said sincerely.

"Yeah…me too," Vince said, walking between Booth and Brennan to head to class. The two partners shared a look.

"You never did really think it was him," Brennan said.

"You did?" Booth asked.

"I'm not sure what to think," she admitted.

"We don't have any concrete evidence to prove it was him," Booth said.

"We don't have any to prove it wasn't, either," she said. "He's got enough connections with employees to know his way around that park, and he's got a pretty good motive now."

"No," Booth said. "He didn't know. That look on his face just now…he didn't know."

"So what now?" Brennan said.

Booth pulled out his phone and dialed Anne Bierle's number.

"Hi, Mrs. Bierle, this is Agent Booth…Uh, no. No, not yet. We're getting there. Listen, what can you tell me about Billie's plans last Christmas break?...Uh-huh…so home for the holidays, then back to Orlando for work?" he said as Anne filled him in.

"Where are you going with this?" Brennan asked. Booth held up one finger to shush her.

"Did she mention any dates or guys or social engagements at all?...Really?...You're sure?...Thank you," Booth said, hanging up the phone. He started heading out of the building immediately, leaving an out-of-the-loop Brennan behind.

"What happened?" Brennan asked.

"I know who the father is!" he called.

"Who?" Brennan called, sprinting after him. "Booth, who is it?"

When they got back to Orlando, Booth and Brennan walked into an interrogation room where Justin Woods already sat. They each took a seat across from him.

"What the hell, man?" Justin asked as they walked in.

"You stayed in your girlfriend's apartment for several weeks last January, correct?" Booth asked.

"Yeah," Justin shrugged. "I had to be back at work before my dorm opened back up for the spring semester. Joanna let me have her room."

"So you and Billie were roommates for a few weeks?" Booth asked.

"Yeah, I guess," Justin said.

"Did you have a sexual relationship during that time?" Brennan asked.

Justin laughed and looked at Booth. "Is she serious?"

"Answer the question," Booth said.

"Okay, yeah," Justin said. "We hooked up four…maybe five times."

"Hooked up?" Brennan asked.

"Yeah, you know, had sex," Justin said as if he were talking to a five-year-old.

"So you cheated on your girlfriend with her best friend?" Brennan asked.

"That bitch cheated on me first! She said she was just in a play with her old high school boyfriend, but come on! I know what that means," Justin said. "If she got to get some over break, I should get to, too."

Booth and Brennan shared a look. Booth sat up in his seat and asked, "Did she ever give you any signals that she wanted more than just sex from you?"

"What, like a relationship? No," Justin said. "She seemed cool with the arrangement…said she didn't have a lot of experience and wanted to change that. I thought…why not? Seemed like the perfect deal to me."

"Did you know Billie was pregnant?" Brennan asked. Justin froze.

"She may have mentioned that, yeah," Justin said.

"How did you respond to that?" Booth asked.

"I wanted a DNA test! She was going to keep the baby, and I wasn't going to let her screw up my life like that without scientific proof," Justin said.

After telling Justin not to go anywhere, Booth and Brennan stepped outside the interrogation room. Brennan pulled out her phone.

"Saroyan," Cam answered in DC.

"Cam, it's me," Brennan said. "Have you had a chance to analyze the blood samples I sent you yet?"

"Yes, but unfortunately, they're all from our victim," Cam said.

"Damn it," Brennan sighed.

"How's it going?" Cam asking knowingly.

"Kid finds out he got the girl he cheated with pregnant…gets her from Space Mountain to the dark pirates ride…kills her to keep her from having the baby…tells her best friend she ran off with someone else?" Booth hypothesized.

"With that cretin, it's certainly plausible," Brennan agreed. She turned back to her phone. "Cam, is there any forensic evidence linking Justin Woods to this murder?"

"Not yet," Cam admitted. "Everything we've got is circumstantial, but Angela and Hodgins are both busy now that our power's up and running. We'll keep you updated."

After hanging up with Brennan, Cam headed into the Imaging Unit. Photographs of Billie's skull and its injury filled one panel of the Angelatron, while Angela worked on a model of Billie and the crime scene on the other panel.

"How's it going?" Cam asked.

"Good," Angela answered. "I managed to find both Justin and Billie coming out of Space Mountain on the security footage, but after that, I lose them."

"And Vince?" Cam asked.

"I didn't find him anywhere but Main Street," Angela said. "So that footage was kind of a bust."

"So what are you doing now?" Cam asked.

"I just finished inputting the data for the injury to Billie's skull and the princess weapon," Angela said. "From the depth of the wound, we can tell the approximate force required in Newton meters to cause the injury to the bone."

"Sounds great," Cam said. "Now what?"

"Now we try to match the force of the blow to the approximate strength of the assailant by using our suspect's height and weight," Angela said. "What are Vince's height and weight?"

"Actually, our leading suspect is Justin now," Cam said.

Angela glanced at her in surprise. "Why?"

"He's the baby daddy," Cam said.

"The jerky colleague?" Angela asked. "Really?"

"College kids," Cam shrugged.

"Okay, then…" Angela said. "Justin's height and weight?"

"His height is about 183 centimeters, and I'd guess about…80 to 85 kilograms, judging from his picture," Cam said.

"Okay," Angela said. She put in Cam's estimates and the figure representing the killer on the screen transformed to fit the measurements.

Angela pressed a button on her control pad to begin her scenario, and she and Cam watched as the killer grabbed the princess toy, swung, and completely shattered Billie's skull.

"Oh," Cam cringed. "That's not good."

"No, not what we were going for," Angela said.

She reset her animation and re-added all of the information to test the scenario again. Upon her second and third trials, she got the same results.

"Can you reverse engineer this?" Cam asked. "Use the injury pattern and the known force to determine the approximate dimensions of the killer?"

"Yeah, I can try," Angela said.

"But, before I call Booth, this definitely rules out Justin, right?" Cam asked.

"Right," Angela nodded. "It wasn't him."

Thanks for reading! Don't forget to review :)

EDITED TO ADD: Some of you in the reviews tonight have been saying that Angela's machine is the Angelator, not the Angelatron. The name of her computer system actually changed when her machine itself changed. The hologram system from the first few seasons was the Angelator, but the new system (the screens we saw in Season 5) is called the Angelatron. This is from the 100 Fun Facts About Bones list, straight from the Fox website:

"The Angelator was 100% VFX. The new Angelatron is 100% real time graphics."

I can't remember if they've ever said the new name on the show or not, so sorry for the confusion!
