A/N: This is a filler chapter that will lead up to the big bang guys meeting the NCIS peeps. It's going to be mayhem!

Chapter 4: Secrecy is of the Utmost Importance

Penny, Bernadette and Amy stood calmly and quietly sipping their early morning coffee as they waited at the gate for the arrival of their Island Friends. The flight that had been forwarded to Penny, and was on time, and as they stood there they saw the passengers starting to disembark from the plane and come through to the main terminal.

"Oh this is exciting," Bernadette stated as she stood on her tip toes to see into the crowd of people.

"Kono" Penny and Amy shouted at the same time as they saw their friend coming through the crowd.

"Aloha," Kono smiled and wrapped her arms around each of the ladies individually.

"Where is Jenna?" Penny asked as the group of five congregated around them and the other woman of their former party was not seen.

"It's a long, convoluted, story and I will tell you everything but you have to promise me a girl's night out to get all the details." Kono smiled. "It's a story that needs much liquor consumed to make it in the least bit tell-able."

"That just happens to be what we do best!" Penny laughed.

Steve and Danny exchanged a worried look as Chin shook his head and Max merely stood by and smiled.

"So, what's the super secret plan Commander?" Penny asked flirtingly.

"Unfortunately, before we do anything remotely fun, we have to work," Steve answered.

"I don't, I'm on vacation. I refuse to look at any bodies." Max stated.

"You can hang with us," Amy smiled, "exploring the world of neurobiology and microbiology."

"Or you could come shopping with me," Penny smiled.

"All sound quite interesting and very amusing," Max stated with a smile, "this is going to be the best vacation ever and I am determined to be completely at your disposal and amused."

"Then it is settled," Steve laughed, "While we deal with the primary reason we've come here, you can show our medical examiner the time of his life. Take care of him Penny; he's an extremely important member of Five-O."

Max blushed.

"Alright, sounds good, where am I dropping you off?" Penny asked with a smiled as the whole party headed toward the baggage carousels.

"This is the address," Steve stated and showed Penny his phone.

"We know how to get there," Danny smirked and motioned to Chin, "It's a boat house and it's a little tricky to find, but we'll help you."

"Alright, well let's get this party started!"

Steve, Danny, Chin and Kono walked into the boat house to see Sam and Callen waiting for them.

"You made it, finally," Sam laughed as he shook hands with Steve and then pulled him into an embrace. "I was beginning to think you were a ghost, but I know better because you aren't one of us." He added with a wink and motioned toward Callen. "This is Lieutenant Commander Steve McGarrett. This is G. Callen."

"What's the G stand for?" Steve asked with a smile as he shook hands with Callen, "Or is that classified information for security purposes?"

"I actually don't know what its stands for." Callen stated honestly.

"Just call him Callen, or G, its all very gangstah," Sam laughed, "and works well for him in our line of work."

"You know the life," Steve chuckled.

"It's good to see you all again," Callen stated, not quite as cheerfully, but pleasantly enough.

"Please let this not be one of those cases where I'm going to have to be inoculated by Hetty," Danny stated sarcastically but seriously all at the same time as he smiled and shook Callen's hand.

"I heard that Detective Williams." Hetty stated as her face popped up on one of the monitors.

"I was vaccinated before I came." Danny stated and threw up his hands in defeat.

Hetty smirked.

"Bring them to me," Hetty ordered as six pairs of eyes turned toward her. "I want you all in opps in thirty minutes!"

"So much for getting ourselves settled." Chin sighed.

"I hope you slept on the plane." Sam laughed.

"Not a wink," Danny sighed.

Max walked into the apartments complex first with Penny, as Bernadette did actually have to head into the lab for work and Amy, though busy with her own research, went into her own lab just to get out of lab duties for the day. Max had made Penny aware of the arrangements that had been hastily made for the five travelers and, as it had been before, Penny was left to check the members of Five-O into their hotel, deposit all of their luggage and make sure that everything was ready for their stay. She sighed to herself seeing the similarity to her own vacationing in Hawaii, but she knew that it had to be done and Max has been most helpful.

As they walked up the several flights of stairs, because Penny was already ready to shower again and changed, they met Leonard and Sheldon coming down.

"Max!" Leonard stated in surprise and confusion.

"Good morning Doctor Bergman," Sheldon smiled.

"Good morning Doctor Cooper, Doctor Hofstadter," Max stated with a smile and a wave.

"What are you doing here?" Leonard asked.

"I am here for Comic Con," Max stated happily.

"But Comic Con is two weeks away." Leonard said.

"Leonard, Doctor Bergman is right to be here early. Comic Con is no laughing matter, you must be prepared and orient yourself with what is happening, familiarize yourself with the convention center and the venders, and understand the lay out of the land before you can enjoy the convention. Also, Max is going to need time to develop his cosplay ideas and he's going to need time to do that because I am sure he didn't bring his costumes with him." Sheldon stated. "You are right to be here early Max. Your thoroughness and organizational skills do you credit. You will have a wonderful time." He added with a smile.

"I don't mean to be rude, Max, I was simply curious as to your being here in our apartment building when you could be in San Diego if Comic Con is your real reason for visiting California." Leonard stated.

"Ah, yes, I see the confusion now," Sheldon stated.

"Penny picked us up from the airport this morning. It was a very spur of the moment trip for all of us." Max explained, "But in two weeks we will all be heading to San Diego for Comic Con." He added cheerfully.

"Who is all here?" Leonard asked.

"Oh, everyone," Max stated, "But they are on top secret business with the NCIS office based in Los Angeles."

"And they didn't tell us?" Sheldon asked sadly as hurt and shock crossed his face, "Surely Commander McGarrett would have called."

"Oops!" Max stated and covered his face, "it was supposed to be a surprise!"

"Oh, well, that I can get behind." Sheldon smiled.

"But you hate surprises," Leonard stated.

"I do when I don't know about them," Sheldon corrected, "but this can hardly be classified as a surprise now, unless, we surprise them. Come along, Max, you will take us to our friends now."

"But we have to go to work," Leonard stated hesitantly.

"We can get out of that," Sheldon stated haughtily. "There are far more important things to be dealing with in law enforcement, Leonard, we much go and volunteer our assistance."

"I don't know if that is a good idea Sheldon, the NCIS crew is very secretive and the case is of a delicate nature." Max explained.

"All the more reason for people familiar with Five-Os procedures to be involved," Sheldon stated, "Come along, men, we much fetch our colleagues from the university and assemble at once. You do know where we are going, don't you?" Sheldon asked as he turned to Max.

"Here," Penny, who had been standing by and ignored the whole time, stated. "This is the location where I dropped off Commander McGarrett and the rest of Five-O."

"Perfect," Sheldon smiled as he punched the coordinates into his phone's GPD, and continued down the stairs.

"Again I get ditched, this is awesome!" Penny stated sarcastically to herself as all three men disappeared down the stairwell.
