Chapter 5: Intruder Alert

"Welcome back," Deeks smiled as the four members of Five-O walked into the office with Sam and Callen. "And hello to you," he added as he jumped forward to greet Kono.

Kono rolled her eyes.

"Aloha," she smiled and shook his hand.

A whistle caught the attention of the whole crew before full introductions could be made.

"Hetty wanted all of you in the opps center six minutes ago." Eric stated from the top of the stairs as all eyes turned on him.

"Blame it on the traffic, Eric," Sam grumbled as the herd followed him up the stairs.

In the opps center they found Hetty watching the monitors as information built up all around her, as Nell and Eric moved with the evidence.

"It's good to see you again detectives," Hetty stated as Chin and Danny entered the opps center.

"Holy cow," Kono gasped at the sight of all the technology.

Steve just smirked as he looked around at the familiar enough set up – he had been in naval intelligence after all.

"Good morning, Miss. Lange," Danny smiled.

Hetty raised and eyebrow to him.

"I'm not the principal, Detective Williams," she stated with a smile.

"Then why do I feel like I've been caught with my hand in the cookie jar?" Danny asked.

"Well how should I know? Are you feeling guilty about something?" Hetty retorted.

Danny shook his head, "not that I'm aware of."

Steve coughed, "Camaro," and cleared his throat.

Danny spun on his partner.

"And you must be Lieutenant Commander Steven J. McGarrett," Hetty stated as she reached out to shake his hand.

"Steve is just fine, ma'am."

"Did your mother name you Steve?" Hetty asked.

"No." Steve answered.

"Then Steve is not fine," Hetty smiled. "It will be Steven or Commander McGarrett within these walls. That is unless you absolutely prefer Steve."

"Do you prefer Hetty over Henrietta, Miss. Lange?" Steve asked with a smirk.

"Steve it is then," Hetty smiled with knowingness about her looks.

"How do you do that?" Danny whispered in his partner's ear.

Steve shrugged with a smile of pride.

"So where is this Kono guy who's got all the inside intell on Frank Delano, and who is too cool for a last name?" Deeks asked and looked around the room.

Kensi face palmed herself feeling embarrassed for her partner.

"I'm Officer Kono Kalakaua, and I'm not cool enough to just be known by my first name." Kono stated and glanced at Deeks. "But I do have all the inside intell on you Detective Deeks."

"We're going to get along just fine," Kensi smiled as Deeks stared on with his foot in his mouth. "It will be nice to have another woman on the crew to kick Deeks' ass."

"On the street or on the water, I'm down." Kono stated confrontationally.

Deeks looked confused.

"Officer Kalakaua has won the national surf championship." Eric stated when Deeks looked around for answers. "This was before she became a cop, but I believe, I mean I know, she still spends a lot of time affiliated with the Coral Prince cooperation and surf club."

"Hello Eric," Kono smiled.

Eric smiled back and then caught Nell's questioning look and turned back to the computer he sat beside.

"You know her?" Deeks asked in shock as he walked toward Eric.

"She's a legend," Eric stated, "You need to spend more time on the water my friend."

"Like I said, I could take you any time, Deeks, you just name the place," Kono smirked.

Deeks fell silent as Kensi laughed at him.

"Alright, Ladies and Gentlemen, it's time to get down to business." Hetty announced as Eric and Nell shuffled images around the room.

"I know these three, but I don't know these two." Steve stated as formal photos of naval officers – including his own – popped up on the main screen in the opps center.

"You know the three victims?" Hetty asked, "But not the hostages?"

A shadow passed over Steve's face and Callen caught it.

"My career in the navy started with these three men. They knew me before anyone else." Steve stated, "David Rodgers, Scott Brooklyn and Philippe Faust were in my unit for basic training. We're talking years and years ago when I first joined up. They were with me through that, all the way to naval intelligence but I lost track of them when I went on to become a SEAL. I haven't seen, or spoken, to any of them in at least ten years, but I might know someone who has."

"Who?" Hetty asked.

"Lieutenant Catherine Rollins. She is stationed out of Pearl, with a permanent seat on the Enterprise." Steve answered. "She works Naval Intelligence."

"Like Star Trek?" Deeks asked with a laugh.

"It's an aircraft carrier," Steve stated.

"Called the Enterprise, nice," Deeks smiled.

"When was the last time your spoke with Lieutenant Rollins?" Hetty asked.

"Just before we left the island," Steve answered.

"Eric, make contact with Lieutenant Rollins and see if she can't tell us something about her colleagues, all of them." Hetty instructed just as an alarm started to sound in the office.

"That's the alarm from the boathouse," Nell stated and jumped for her computer.

Within moments all of the camera feeds from the boathouse were up on the screens.

"There are five people lurking around the boathouse." Nell stated.

"How did they get in there?" Sam asked in shock.

"They're with us," Steve stated as he saw the video feed of Max, Sheldon, Leonard, Howard and Raj.

5-0-NCIS:LA-TBBT

"Sheldon, what are you doing?" Steve asked as Sheldon jumped, spun around and looked at the plasma screen that had sprung to life behind him.

"Ah, so it is true, you have come to California without giving us the information to prepare for your visit!" Sheldon scolded as he looked at the screen.

"It was supposed to be a surprise!" Steve stated.

"We were quite surprised to see Doctor Bergman with Penny this morning." Leonard stated.

"But more surprised to hear that Detectives Williams and Kelly were in California recently and didn't have the common decency to make contact with their old friends." Sheldon scolded.

"It was a top secret operation, Sheldon, we were sworn to secrecy. We couldn't have called you even if we wanted to." Chin explained.

"We had every intention of coming to you this time around. In fact, we are inviting you to come out for Pizza tonight." Steve smirked.

"Well it is Pizza night," Sheldon stated and his mood lightened a little.

"Seriously, you are using state of the art technology to make a dinner date?" Deeks asked as he broke into the conversation.

Silence fell between the Five-Os and their friends.

"How did you get into that secured location?" Sam asked to break the uncomfortable silence that had developed as he shot a look at Steve.

"We are physicists, a little lock is no match for the awesome force that is my intelligence," Sheldon stated haughtily. "Who are you?"

"I'm Agent Sam Hanna, NCIS, and you have broken in to a top secret government safe house. We were about to have you arrested."

"No need to jump to conclusions, Agent Hanna, I'm certain that our friends and colleagues from Five-O will vouch for our being here." Sheldon stated.

"Sheldon, what are you doing in the boathouse?" Steve asked when the questioning had circled long enough.

"I'm looking for you, where are you?" Sheldon asked. "Penny gave us the address for the location that she dropped you off at and Max helped us find our way here. So, again I ask, where are you?"

"I can't tell you that," Steve sighed as Hetty shot him a warning glance. "Why are you looking for us? I'm sure Max told you we would find you."

"I did, this isn't my fault, please don't arrest me." The frighten Medical Examiner stated as he jumped into the frame.

"We have come to lend our assistance," Sheldon stated, "We aren't getting arrested." He added confidently. "As before, we are at your service Commander."

"I assure you, you may be arrested," Hetty stated, "if you don't leave that location immediately and forget you ever saw it."

"We're leaving," Howard stated frantically as he grabbed Sheldon's arm.

"I beg your pardon, ma'am, but we are not going anywhere until we get some answers!" Sheldon stated as he broke out of Leonard's grasp. "We have assisted Five-O on a case before. We are well aware of their operating protocols."

"This isn't a Five-O matter, it is an NCIS investigation," Hetty corrected.

"Then it shouldn't matter to you, or your investigation, if you hand over our friends to us." Sheldon stated.

"They are part of this investigation," Hetty corrected but a smile spread across her face.

"Then so are we," Sheldon stated putting his foot down.

"As far as we can tell, at this time, there is nothing scientific about this case, Sheldon." Steve stated, "We'd love for you to help, but this has nothing to do with you."

"But it may," Sheldon stated.

"Sheldon, you're going to get us all killed!" Howard yelled, "Let's go!"

"I am not going anywhere," Sheldon stated and sat down in one of the chairs. "No, I will call their bluff, I am not going anywhere until I see Steve and Danny and they give us some answers, or we are aloud to offer our expertise. You dare not say no to three physicists, a medical examiner and an engineer. We are assets to the Five-O task force."

"Sheldon, I wouldn't play with these people if I were you," Danny warned.

"You say that you have a Medical Examiner on hand?" Hetty asked.

"Yes ma'am, I'm Doctor Max Berman. I work for the Honolulu Police department and I have been assigned specifically to cases pertaining to Five-O," Max explained. "but I am on vacation."

Hetty and Callen exchanged a silent glance.

"Eight of you, go back to the boathouse and settle this." Hetty stated with a smirk on her face.

"On our way," Callen stated and Five-O followed the Agents out of the opps center.

"And Agent Callen, bring me that Medical Examiner." Hetty ordered.
