"Family isn't about whose blood you have. It's about who you care about." – Trey Parker and Matt Stone, South Park

Angela and Wendell took turns sneaking around the lab to spy on Brennan. At first, Wendell felt bad for being shifty around his doctoral advisor, but he cared about Brennan deeply and wanted to know what was going on with this mystery guy.

Angela, on the other hand, seemed to be out of the loop by Brennan's own doing. She was hurt by her friend's inability to share this beautiful man with her but Josh was just so delicious, Angela understood why Bren had kept him a secret.

"Hey, Baby, is there somewhere I can change? This suit is killing me," they heard Josh say.

"The bathroom is just around the corner. We can go to the diner after you change. Booth, will you be joining us?"

"Nah, Bones. I should let you two catch up. I can pick something up for lunch at Wong Foo's, plus I have some stuff I need to do at the Hoover anyway."

Angela watched Josh walk into the men's restroom in a suit and emerge minutes later in jeans and a t shirt, exposing some subtle skin art that was hidden by the sleeves.

"Mmm, he gives Booth a run for his money," Angela mumbled.

"I'll see you later, Bones. If you get something on the case, call me."

"Of course, Booth," she smiled at him.

"Okay, Baby," Josh said, approaching the partners, "Let's go. I'm starving!"

Brennan grabbed her bag and jacket and followed Josh out the door. Angela ran straight over to Booth.

"Wow. I mean…Wow. Did you see him? How long has she been hiding him from us and why hasn't she been sharing?" Angela gushed.

"I'm sure that's why she didn't tell you about him," Booth mumbled.

Angela swatted him with the clipboard she was currently holding but smiled in spite of herself. "So how long have they been together? I'm sure she's told you. She tells you everything."

"It's not like that. Hey, can I use your computer? I need to check a few things and I really don't wanna go all the way over to the Hoover."

She slowly shook her head but let him follow her into her office.

"You're going to do a background check on her new dude, aren't you?"

"He's not exactly her boyfriend, Ange."

That piqued her interest. "Just a fling? Friends with benefits? Spill."

"They lived together. A long time ago."

"Wow! So it was serious! And this guy wants to get back together?"

"No! Angela, let me finish! Josh and Bones were foster siblings."

Angela made a silent 'Oh' and passed the keyboard to Booth.

"Wait…why was he calling her 'Baby'?"

Booth just shrugged and typed Josh's name into the FBI database. It didn't take long for them to find Josh Marshall. He was just as successful as Brennan, all things considered. He was a lawyer who specialized in family law in the Chicago area.

"I should hire him. Maybe I'll get custody of Parker," Booth muttered, "Look at all of those names."

"Booth, that just means you can't afford him. Those are some high profile names! Celebrities, politicians…Sorry, G-man. Well, he looks okay. No criminal record. Graduated from Burtonsville High, same as Bren. Went to Loyola for undergrad and law. Loyola is only about ten minutes from the Northwestern campus. They must be really close."

Booth laughed a skeptical laugh. "Where has he been when she needed someone, when Epps and Taffet wanted to kill her? I doubt they're that close."

"I don't know, Booth. She tried for all of three seconds to stay at work and then gave in to him when he took her to lunch. How often does she do that for you? She works and you have to pull her into her office to scarf down a carton of Wong Foo's."

"Bones and I go out to lunch!"

"Yeah, maybe when you're on your way to question a suspect, but when she's in the lab, you know there's no way you're getting her out of there."

Booth didn't say anything. She was right.

"Why was he calling her 'Baby'?" Angela was not about to drop it.

"I'm gonna go have lunch," he said.

Booth handed the keyboard to Angela and ran out the door to join Bones and Josh at the diner.

"So how have you been, Baby?"

She smiled at Josh and said, "Good. Things are going well. Things are going well at the firm?"

He nodded. "Yeah, since they made me partner, I've gotten several high-profile clients. You know anyone around here who needs help with adoption or custody?"

Brennan shrugged. "Booth might. He has a son he doesn't see much. I thought I told you about that."

"You did. His kid's name is Parker, right?"

"Yes. Josh, why are you here?"

"I missed my sister!" he said with a laugh.

"Biologically, I am not your sister. We met each other purely because we were placed in the same household during our time in the foster system."

Josh stood and moved to the other side of the table to take the seat next to her. They were sitting at diner, waiting for their food and sipping on coffee. She missed Josh. Though he was a reminder of what she had wanted to leave behind, she cared for him very much.

"Well, Kathy and Chris always thought it was important that we thought of them and Katie as our family. You and Katie were best friends! They were our family. Kathy still is. We're still family, Baby."

"I know. This is going to be hard to explain to my coworkers though."

"You didn't tell them about me?" he faked a hurt look.

"I don't like sharing my personal life. You know that," she scolded.

"I know, I know. Hey, isn't that your partner?" Josh asked, pointing out the diner window.

"I thought he was going to eat lunch at the Bureau," she muttered.

"Hiya, Bones! Hi, Josh," Booth said as he took a seat across from them.

"Hi, Agent Booth," Josh said, "I'm glad you decided to join us."

The waitress brought Brennan and Josh's food and promised Booth she'd put his order in right away.

"Me too. So tell me, Josh, why did you decide to go to Loyola? Is it so you could stick close to Bones?" he asked, snagging a cherry tomato off of Brennan's salad and popping it into his mouth.

"Booth!" Brennan stood and pulled her partner off of his chair. Dragging him to the counter, she asked, "You ran a background check on Josh?"

"Yes."

"Why?"

"I gotta make sure the people you hang out with are okay, Bones. You do have a tendency to date the wrong type. Do you want me to remind you? There was David-ˮ

She cut him off. "No. I don't need you to remind. And Josh is my brother."

"Not really."

"Blood doesn't matter to us," Josh said from behind them, "Your burger is here, Agent Booth."

Booth looked at the table. His cheeseburger and fries were indeed sitting at his spot. The two returned wordlessly to join Josh.

"You didn't have to run a background check on me, Agent Booth. You can ask me whatever you want. I'll tell you whatever you want to know about me. Or about Baby."

The two men earned a mischievous look on their faces.

"Don't you dare, Booth," Brennan warned.

"Why do you call her Baby?" Booth asked, ignoring his partner.
