"Dr. Brennan, Agent Booth thank you so much for meeting us here today." NCIS Director Jenny Shepard said as she looked at the two partners. "I really appreciate you two coming all the way to NCIS headquarters."

"No problem at all…. Agent Fornell always spoke nicely about this place." Booth said with a smile as he took a seat.

"Yes well I wasn't given much of a choice." Brennan answered.

"Bones." Booth pleaded with his partner of Eight years and girlfriend of two.

"What?…. I'm sorry Director Vance but I do have better things to be doing with my time."

"Such as?" Jenny asked trying to hide the amusement in her face.

"Identifying the remains that are in Limbo…. My publisher is frequently calling asking about the next chapter in my book."

"Yes but are any of those things governmentally important?" Brennan glared at Booth knowing he had just beaten her. He retaliated with a charm smile he knew she couldn't resist.

"As I was saying." Jenny spoke up again getting the attention of the two partners. "Two soldiers were found dead this morning in Marengo Illinois….. One was a marine the other was a ranger both brothers, both were brutally murdered along with their wives."

"So this is an inter agency cooperation?" Booth asked as he looked at the files of both men. "Cody and Mark Kilmer. Four years apart in age."

"Booth Mark looks a lot like you." Brennan said as she looked at the photo.

"Fornell specifically suggested you for this assignment Agent Booth."

"Why is that?" Booth asked curiously as he thought back to the brief encounters he'd had with the distinguished agent.

"Says you remind him of one of my top men." Jenny answered with a smirk. "Now you and Dr. Brennan will be working with two of my top agents." Their was a knock at the door. "Come in."

"You wanted to see us Director?" Brennan looked over and saw a woman walking into the room she stood at attention making Brennan's job easier to examine her.

"5'7 chocolate Brown Eyes, long curly hair, Israeli descend, very pretty." Brennan thought as she looked at the woman.

"Ziva where is Tony?" She asked as he looked past the woman.

"Right here Director." This time Booth turned to see a man around his height walk into the room. Brennan did a double take as she looked at her partner and the man named Tony. They were almost the spitting image. Booth was slimmer than DiNozzo and his eyes were blue instead of the warm brown she was used to seeing, but asides from that they could pass as brothers.

"Special Agents Anthony DiNozzo and Ziva David I'd like to introduce you to Special Agent Seeley Booth and his Partner Dr. Temperance Brennan of the Jeffersonian." Tony looked at Brennan and smiled. Ziva rolled her eyes as she knew that look on his face.

"Very Special Agent Anthony DiNozzo at your service." Tony said grabbing Brennan's hand. Brennan looked at him for a second before quickly taking her hand back from his grasp. Ziva let out a small chuckle.

"Nice to meet you." Booth said standing up from his chair. Ziva looked over at Brennan who was rolling her eyes as she watched his protective nature take over.

"So you're the Fed we're going to be working with?" Tony asked eyeing Booth up and down.

"Looks like it." Booth answered as he looked over at Brennan. "What do you think Bones?"

"There are some strong characteristics between the two of you." She said as looking up from the files in her hand. "Similar bone structures."

"What she talking about?" Tony whispered to Booth.

"She's saying you two could pass as siblings." Ziva said staring at Brennan.

"Really?" Booth asked.

"Yes." Brennan answered.

"That's good to know." Everyone looked towards the door as a man walked in. his silver grey hair swayed with every step he took. Booth took a deep breath as the man stopped in front of him.

"Shrimp." The man said with a smile as he took a sip of his coffee.

"Uncle Gibbs." Booth answered with the same smile. Brennan, Ziva, Jenny, and Tony all stared at the two of them.
