Hi again! Thanks for the reviews on the second chapter. This is the end of the story, and I'm pretty sure I actually mean it this time, lol. I really had fun writing this story, so I hope you all had fun reading it, too.

By the time Booth left Brennan's office, Zack had already rejoined his colleagues on the platform. Angela had tried twice to ask what that impromptu meeting was about, but both times, Cam had thankfully told her to gossip later and focus on the case. A few minutes after he arrived back on the platform, Booth left Brennan's office and without a word to anyone, left the Medico-Legal Lab.

"Where is he going?" Cam asked Zack.

"I don't know," Zack said.

"He wanted an update," Cam reminded him.

"I guess he forgot," Zack shrugged.

"Okay, seriously, what happened?" Angela asked.

"Umm…nothing," Zack said as he noticed Brennan coming out of her office as well. "Am I needed at the moment?"

"I guess not," Cam said. "You can go back to analyzing the evidence you were looking at earlier if you'd like."

"Thank you, Dr. Saroyan," Zack said.

He walked down the platform steps as Brennan walked up them. As they passed, they shared a glace briefly, and Brennan's cheeks began to flush with embarrassment.

"Sorry about that," Brennan said. "What's going on?"

"That's what we'd like to know," Hodgins asked.

"That was nothing," Brennan said. "Can we please just focus on the case?"

Cam, Angela, and Hodgins all shared puzzled looks as they began to update Brennan on the case.

The day passed, and Booth, Brennan, and Zack skillfully avoided one another. Either Brennan or Zack were in their offices for almost the entire day, and Booth hadn't returned to the lab since that afternoon. He kept himself updated through phone calls to Brennan or Cam, and the one time he needed Brennan to go with him, he had waited patiently in the parking lot when he came to pick her up.

Around seven, Angela appeared in the doorway to Brennan's office. Brennan was on her computer but looked over when Angela knocked on her door.

"Hey, sweetie. Hodgins and I are heading out. Do you want to come to dinner with us?" Angela said.

"No, that's okay. Is everyone else leaving, too?" Brennan asked.

"No, Cam's busy with the body, and Zack's still in his lab," Angela said. "Cam said she'd probably be about another hour, and I don't know about Zack."

"Oh…Zack's staying late tonight?" Brennan asked.

"Yeah," Angela said. She paused for a minute. "Did you and Zack have a fight?"

"No. Why would I fight with Zack?"

"I don't know, but you guys have seemed a little…weird today. That's all," Angela said.

"Oh…no, we're fine," Brennan insisted.

"Okay, if you say so," Angela said. "See you tomorrow."

"See you tomorrow," Brennan said.

Angela turned and left the office. She met Hodgins in the main part of the lab.

"Zack's staying?" Angela asked.

"He seemed kind of reluctant to stay when he found out Brennan was still here, but yeah, he's staying," Hodgins said.

"Something's definitely going on with them," Angela said.

"Oh, absolutely," Hodgins agreed.

"Booth must be involved, too. He hasn't been back here since he dragged Zack off the platform earlier."

"Well, how are we going to find out what it is? They obviously don't want us to know," Hodgins pointed out.

"Don't worry," Angela said. "When Zack gets home tonight…we'll find out."

At exactly eight o' clock that night, Booth entered the Medico-Legal Lab. Luck wasn't on his side, however, because he bumped into Zack almost immediately after walking in.

"Agent Booth," Zack greeted.

"Hey, Zack," Booth said. "Excuse me." He quickly began to walk towards Brennan's office.

"Oh, I think Dr. Brennan left already," Zack said.

"Really?" Booth asked.

"Yes. Her blinds are shut, and it appears to be dark in there," Zack said. "That's normally how she leaves her office for the evening."

Booth smiled slightly. "You know…I think I'll go check anyway."

A look of realization crossed Zack's face, and Booth chuckled slightly. Zack took a deep breath. Thank God he was on his way out for the evening. Cam entered the main part of the lab just as Booth disappeared into Brennan's office. She was getting ready to leave for the night as well.

"Was that Booth?" Cam asked.

"I don't know," Zack said.

"What do you mean you don't know?" Cam asked.

"It might've been Agent Booth. I've only been out here for a few seconds."

"Oh. That's okay. I'll just go see for myself," Cam said.

"No! Don't go in there," Zack said.

"Why?" Cam asked.

"Agent Booth and Dr. Brennan are in there," Zack said.

"So?" Cam asked. "This will only take a second."

"No!" Zack said again.

"Zack…what's going on?" Cam asked.

"I don't know anything!" Zack insisted and quickly walked out of the Jeffersonian.

Zack left Cam with a very confused expression on her face. Cam stood in the lab for a few moments, trying to decide why her employees had been acting so weird today. Of course, Zack was always a little bit weird, but this was getting ridiculous. It was like the couldn't work together anymore! She walked over to Brennan's office. She really needed to talk to Booth about the case, though Zack seemed very insistent that she not bother them this evening.

Maybe they're in there having sex. No, that's not possible. Seeley would never risk getting caught doing that, Cam thought to herself. She laughed at the absurdity of the thought of Booth and Brennan sleeping together in the middle of the Jeffersonian, decided to wait and talk to Booth tomorrow, and headed towards the parking garage.

"Hey, Bones," Booth said, shutting the door behind him.

"Hey," she said.

Brennan was sitting in the middle of the floor, case research spread out in a circle around her. The overhead light was off, and various lamps around the room bathed the office in a dim light. Booth brushed some of the paperwork out of the way and sat down on the floor opposite her.

"Are we alone?" Booth asked.

"I don't know. Cam said she was leaving around eight, but I don't know about Zack," she said honestly.

"Zack's on his way out. I passed him when I came in," Booth said.

"Then we're alone," Brennan smiled.

"Well, in that case…" Booth started.

He gently lowered Brennan to the floor and climbed on top of her, using his elbows to support his weight. He began kissing her lips firmly, and she instantly responded, curling her arms around his back. He lowered his body onto hers, and she moaned at the contact. Brennan slid her arm down his back as they kissed and slipped her hand inside the back pocket of his jeans. Booth undid the belt around her waist and tossed it aside. He then pushed her shirt up to rest just under her breasts and began kissing the soft skin on her stomach. Brennan reached down to the bottom of his shirt and tried to pull it over his head. As soon as she got his shirt off, Booth suddenly pulled his mouth away from her stomach and rolled off of her, looking towards the door.

"What?" Brennan asked.

"I'm just checking the door. You know, making sure it's shut," Booth told her.

"It is," she giggled. "Are you okay?"

"Yeah," he said. "Yeah, I'm good."

Booth lay back down and began kissing her again, slowly moving back on top of her body. He slid one of his hands up under her skirt, caressing the smooth skin on her thigh, and she gently pressed her hips into his, telling him to continue. He began to tease along her panty line and used one of his legs to nudge hers apart. Booth began kissing her neck as his fingers slipped beneath her panties to touch her. He felt Brennan tense up as his fingers traveled over her soft folds, and he stopped his movements and picked his head up to look at her.

"Are you okay?" he asked.

She chuckled nervously. "Of course. Keep going."

"You feel kind of tense," Booth said.

"I'm okay. I promise," Brennan said. "Please, Booth. Just kiss me again."

He leaned his head down to meet her lips again and used his tongue to tease her mouth. She kissed him back and held onto his face to keep his lips in place over hers. Booth began caressing her hips and thighs again, but when he tried to tug her panties down her legs, he felt her tense up again.

"Bones," he said, rolling off her body.

"What?" she asked. "I'm sorry."

"You don't have to be sorry, baby," he whispered, kissing her softly. "That kid has completely ruined this place for us, hasn't he?" Booth asked.

Booth sat up against one of her chairs, and she slid into a sitting position as well, grasping one of his hands in hers. She stroked his skin softly as she looked around her office. She felt ridiculous.

"Maybe not forever, but for right now, I think he may have," she said.

Booth sighed as well. "Bones, it was horrible. I bumped into Zack on my way in, and he told me he thought you had gone home because your blinds were shut and the lights were off, and then when I told him I'd go check to make sure you were really gone, he gave me this smug look like he knew exactly what we were going to do in here."

"Well, he probably did," Brennan said. "So what do we do now?"

"Kill Zack?" Booth suggested. Brennan shot him a look.

"Why don't we just go over to my place?" she suggested.

"We could…" Booth said. He didn't sound too thrilled by that suggestion.

"What?" she asked.

"It's more fun here. The sex isn't always as good when we're at home."

"That's sometimes true, but we got caught, Booth. It was more fun here because there was a danger of someone catching us. Now that someone has, that thrill has been replaced by anxiety and fear," she said.

"There's always my office," he suggested.

"How is an FBI agent catching us better than Zack catching us?" Brennan asked.

"Almost anyone would've been better than Zack seeing us having sex, Bones," Booth said.

"Do you really want a repeat of today with one of your coworkers?" Brennan protested. Booth shook his head no. "It doesn't matter where we go. I just want to be with you."

He kissed her softly. "I want to be with you, too."

The couple began kissing again. Brennan pushed Booth up into the chair, and she sat down on top of him. He instantly wrapped his arms around her waist to hold her in place. Brennan slid her hand down his chest and stomach and began working on his belt buckle, trying to undo it. Booth grabbed her hand and stopped her.

"What happened to anxiety and fear?" he asked her.

"Well, it's good to face your fears, right?" she shrugged. She smiled. "So that's what I'm doing. You're right. It's more fun here."

"Bones…" he said.

"You know, leaving the lab because we think someone's watching us even though the blinds are closed would be like letting Zack win. You don't want that, do you?" she taunted, knowing that Booth would never want to admit defeat.

"Are you going to be okay doing this here?" he asked.

"Are you?" she asked as she pulled his belt buckle open.

"Of course," he said, stepping up to her challenge. "Just…one thing."

He reached down, pulled her stilettos off her feet, and tossed them across the room. She shot him a confused look.

"I thought you liked those?" she said.

"I did…until I found out I wasn't the only one who had been admiring you in them," Booth said. "You're going to need to get a new pair."

Brennan frowned. "Okay, but please don't remind me of the fact that my student saw me in nothing but lace and high heels."

"Sorry, but you know, Bones…he was right about one thing," Booth said.

"What?" Brennan asked.

"You really are quite beautiful," he whispered before pulling her lips down to meet his once again.

When Zack arrived at home, he found a note taped to his front door requesting his presence in the main house. He frowned when he recognized the writing as Angela's. Zack reluctantly made his way up the driveway to Hodgins's mansion, knowing that Angela was about to interrogate him on just what the earlier spectacle with Booth and Brennan was about.

He walked into a side door on the main house and called out Angela's name. She responded instantly and told him that she was in the living room. Zack walked into the living room and found Angela sitting on the couch waiting for him. He knew that being left alone with a curious Angela was never a good thing. He had once heard Booth mention that Angela had a sixth sense for all things sexual, and he really was afraid that Booth would actually shoot him if anyone found out. Zack felt his nerves grow as he noticed Hodgins was also in the room. Great. They were going to double-team him.

"Zack," Angela started. "Sit down. How was the rest of your evening?"

"Fine, thanks," Zack said, sitting next to Hodgins. "Though I'm scared it's about to get a lot worse."

"Why would you think that?" Angela asked innocently.

"You have a mischievous look on your face," Zack said. "That usually means you're up to something."

"I'm not up to anything Zack. I was just discussing our very interesting case with Hodgins," Angela said.

Hodgins was sitting next to Zack, forcing himself to hold back laughter. Angela was really laying on the innocent act tonight, and, even though Zack had a tendency to be extremely literal, it didn't seem like he was buying it.

"It is a pretty interesting case," Zack agreed. "What do you think Hodgins?"

"Oh yeah," he laughed. "Today was pretty interesting."

"You know what the most intriguing part of all was?" Angela asked.

"What?" Hodgins asked, knowing what was coming. He couldn't believe he got talked into helping Angela interrogate Zack.

"When Booth grabbed Zack's collar, dragged him off to Brennan's office, and made Brennan stop working to go in there as well," Angela said. "That was definitely an unexpected twist to the day's events. Wouldn't you agree Zack?"

"Y-yes," Zack said.

"So why don't you fill us in on what that was about?" Angela said.

"No, that's okay. I don't really feel like sharing," Zack said.

"But something's obviously bothering you, Zack. Once Brennan came out of her office, you barely left yours all day," Angela pointed out.

"Coincidence, I guess," Zack shrugged.

"You don't believe in coincidences," Angela reminded him.

"That's right," Zack remembered. "I don't."

"So why you just tell me what's wrong? I might be able to help," Angela said.

"There's no problem. Nothing's wrong. I'm fine," Zack said.

"Did something happen with Brennan, Zack?"

"Something like what?" Zack asked, a confused look on his face.

"Everyone…except her of course, knows that you always had a bit of a crush on her, and I'm her best friend. I know how lonely she gets sometimes. Did something happen between you?" Angela asked.

Angela knew there was no way Zack and Brennan had hooked up, but she was hoping that bringing up that possibility would get Zack to admit what was really going on. Hodgins couldn't hold it in any longer and finally let out a little snicker. Angela really was putting on an Emmy-worthy performance tonight.

"No. Of course not," Zack said. "And I really don't think she's that lonely, Angela. She has Booth."

Angela's face lit up. Her plan was working exactly as she wanted it to. Hodgins, however, looked almost embarrassed to be a part of this.

"Booth?" Angela asked. "Is something going on with Booth and Brennan?"

"I don't know," Zack said immediately.

"Zack…" Angela warned.

"I really don't know anything!" Zack exclaimed. "Even if I did, I couldn't tell you." He immediately shut his mouth, realizing what he had just said.

"Oh my God!" Angela exclaimed. "Is there something going on with Booth and Brennan? Are they together?"

"No," Zack said.

"Did Booth threaten to shoot you if you told?" Angela asked.

Zack couldn't believe it. Booth was right. She really did have a sixth sense for this sort of thing. He was too dumbfounded to respond and just sat there staring at her.

"Angela, can we stop with the interrogation now and let the poor kid go to bed?" Hodgins asked.

"In a minute," Angela said. "Zack, I'm going to take your lack of response as a yes, just so you know."

"That's your prerogative, I guess," Zack responded.

"I won't ask anything else after this one last thing, I promise," Angela said. "How did you find out?"

"If Agent Booth asks, I didn't tell you anything. You figured it out!" Zack said.

"Of course. I won't get you in trouble," Angela said. "But really, Zack, you can't tell me anything? Not even one little tidbit?"

"You can ask Dr. Brennan for details," Zack said. "But it all started with a pair of black stiletto heels."

Well, we've reached the end of this little tale. Please leave me a review to tell me what you thought of the ending. Thanks for reading!
