So I originally had this great Christmas chapter idea to post before Christmas, but that did happen. I couldn't get into it for some reason. So enjoy this chapter instead. And a belated Happy Chanukah and Merry Christmas, Happy Friday, Happy Boxing Day, and Happy Kwanza to my readers. (If I missed your holiday I'm sorry!)

I don't own any characters that come from NCIS and its spinoff NCIS Los Angeles. I'm making a profit… JK! No profit in this for me! I just own Kate, so don't sue me!

Kate's 18 in this chapter and I don't know exactly how she managed to pull this trip off, but she did it!

Read and Review :)!

PS I listening to the official NCIS Soundtracks as I type this chapter and I love the music from Abby's Lab. My music tastes are slowly being changed by this show! (I really love the remix of the theme song!)

"So you're going to Los Angeles?" Eighteen year old Kate Gibbs asked her father excitedly.

"Yup." Jethro said as he packed some of his shirts in his overnight bag.

"Is Callen going to be there?" Kate prodded from the doorway.

"Ahuh." Jethro replied as he folded up a pair of chinos.

"Anything other than monosyllabic responses today, Dad?"

"Nope."

"McGee going with you?" Kate asked sighing.

"Yes."

"Can I come too?" Kate asked hopefully.

"Yup." Jethro said as he zipped up his bag. "Go pack."

"Thank you!" Kate squealed as she ran down the hallway to her room.

"Thank your mother!" Jethro called out after his easily excitable daughter.

"I will!" Kate yelled back.

May 3, 2009

Seven hours later, Kate, Gibbs, and McGee got out of the rental car outside of the OSP office.

"Boss, are you sure that this is the right place?" McGee asked as they took in their surroundings. They had parked in an alleyway with buildings with crumbling facades, dumpsters were everywhere and Kate stifled a scream when a rat dashed out over her foot.

Jethro just pointed to the revolving security camera as Kate jumped onto McGee's back.

"Hey!" McGee protested.

"There are rats." Kate said. "I hate rats and they scare the beejesus out of me."

Kate slid off of McGee when the service elevator made it to them and she practically ran to it to avoid the rodents that made the alley their home. Kate's blond hair was secured in twin French braids and they bounced as she ran reminding Jethro of when Kate was a little girl.

A brunette woman in jeans and a nice vest slid the elevator grate opened and said, "Hi, welcome to SP. I'm Kensi."

"Special Agent Gibbs," Jethro said gruffly.

"Agent McGee." Tim said and he shook Kensi's hand.

"Kate Gibson." Kate said with a smile. Abby was test SP's ability to crack deep cover aliases and Kate was the guinea pig. Her cover as NCIS Probie Agent Kate Gibson should be able to stand up under even some levels of CIA scrutiny.

Kensi smiled as she slammed the grate closed. "You sail, Agent McGee?" She asked seeing the issue of Boat Builder's Digest in McGee's hands.

"Uh, no." McGee admitted.

"Build boats?" Kensi prodded.

"Nope." McGee said. "It's a conversation starter."

"It works." Kensi said awkwardly. "So you guys get any sleep on the flight?"

"Not a wink," Tim admitted. Kate stood next to him and stifled a yawn.

"Slept the whole way." Jethro said with a smirk.

"Cat naps between turbulence." Kate grumbled as Kensi opened the door at their floor.

"Ever been here before?" the SP Agent asked as she led them down a hallway.

Jethro said "yeah" as McGee and Kate both said "no."

Kensi chuckled to herself. These three would be fun to mess with later. "Buckle up." She said as she opened a titanium door.

"NSA is worried about the Horn of Africa, Somalia in particular." Director Vance's face was on the large MTAC screen while he conversed with a woman from SP.

"Increased chatter?" the older blond woman asked.

"Quite the opposite." Vance said. "All they're hearing is crickets."

"Well, maybe the bad guys have all given up and gone home." The woman mused as she shifted her weight from one foot to the other.

"Or, maybe they're on their way to the US." Kate said loudly as they descended the stairs into the inner workings of the SP office.

"You took the words right out of my mouth, Agent Gibson." Vance said.

Kate could see the grin tugging at the corner of his lips.

"My Mama says I do that all the time, Sir." Kate said as several heads turned to watch the new arrivals, including the blond.

"Gibbs." Vance said as the NCIS Special Agent walked into his view.

"Hello, Director Vance." Jethro said.

"I know how excited you and Macy are to be working together." Vance said. The Director wasn't wasting anytime by beating around the bush.

There was an awkward moment of silence as Kensi, McGee, Jethro, Macy and a bearded man looked anywhere but at each other. Kate was confused for a second until she realized something. 'Oh!' she thought, 'Agent Macy must be the MP that Uncle Mike told me about that investigated Dad eighteen years ago. This is waaaayy Hinky.'

"I told SecNav I'd have my best people on this one." Vance said continuing, most likely unaware of the new tension in the room. "There are a lot of nervous people at the Pentagon. Don't make me have to come out there." He threatened as he signaled to a tech, most likely Kate's friend Charlie, to cut the feed.

Macy turned to Jethro with her hands on her hips, effectively starting a six way staring contest. "He tell you I got the lead?" Macy demanded.

"Yeah, he told me." Jethro said in a monotone voice as he crossed his arms over his chest.

"You still drink coffee?" Macy asked as she began to lead Jethro out of SP's MTAC.

Jethro just followed her silently.

"Can you say 'awkward'?" Kate asked Kensi and McGee.

The female SP Agent just laughed. She had a feeling that she and Kate would get along great.

"That's Nate, right?" Kate asked as the bearded guy from earlier left MTAC after a brief phone conversation.

Kensi nodded. "Did Gibbs brief you on the flight?"

"Nope." Kate answered as she pulled out her laptop and connected to SP's Wi-Fi. "He filled me in at the airport while McGoo was debating between Boat Builder's Digest and Sniper Monthly.

"He briefed you?" McGee asked. "No fair."

"Which one of us is the totally green Probie with almost zip field experience?" Kate asked sweetly.

"You." McGee replied.

"Hence the itty bitty briefing." Kate said as Jethro came back and grabbed McGee before leaving MTAC again.

Fifteen minutes later McGee was back looking a little dejected.

"Hey, Timmy." Kate said as she minimized the HULU window she'd just opened. "I thought you were going out with the Bossman."

"He's visiting a 'friend'." McGee told her. "What are you watching?"

"Army CID." Kate replied. "It's like what you guys do at NCIS without real dead bodies and the ick factor. I'm officially addicted."

"Or Colonel Mann." McGee added as he took the empty console next to Kate.

"That too." Kate said happily. "Who needs that home wrecking Army bitch anyways?"

Tim just laughed as four people gathered around a bald African American man named Sam Hanna. He was Callen's SP partner and because they spent so many hours together everyone assumed the former Navy SEAL always knew where Callen was. Sam was pulling u an image from Google Earth on the Smart Board like screen.

"The meeting's at a diner in Venice Beach." Sam was saying to the gathered Agents. "We have a traffic camera at the intersection, store security across the street and two preplaced minis inside of the diner."

"We up?" Macy asked Sam as she approached him and adjusted her ear piece.

"Coming on stream." Sam replied.

Macy nodded. "Kensi?" she asked.

"Fifteen minutes out." Sam said. "Kickoff's in thirty."

"Callen?" Macy asked hopefully.

Sam just scoffed and raised an eyebrow. Macy rolled her eyes and turned to Nate. The six foot six shrink shook his head 'no', indicating that he hadn't seen Callen at all that day.

"Who's Callen?" McGee asked playing dumb. Nate just chuckled.

Five minutes later Kate had relocated to a dark corner where she could see everybody, but only Sam and McGee knew where she was hiding. Kate's attention was split between Lt. Col. Mark Weatherly and his Army CID team and the SP op being run right in front of her.

Kate looked up when she heard Macy firmly say, "Callen, we're done."

"Oh, great." Kate whispered. "Just what I need, a dead Callen. Way to go G, the Genius."

Kate calmed herself when she saw Sam smirk at something Callen had said and winked at the girl. Other than Callen and the presently absent Hetty, Sam was one of the few people at the LA SP office who knew who Kate really was.

"Got the play back on Talia's call!" Eric called from his computer.

Macy and the group migrated to Eric's work station. Since Kate lacked an ear piece she couldn't listen in to the conversation.

"The quality sucks, Mace." Eric told his SAC.

"Replay and isolate the last word." Macy ordered.

Eric did as ordered.

"There's our connection." Sam said. "Same guy Chandler was meeting."

'Who?' Kate signed to McGee over her laptop screen.

McGee discreetly took out his iPhone and texted 'Liam' to Kate.

"The same guy." Macy repeated sounding a little aggravated.

~o0o0o0o0o0o0o0o~

Kate sat on the floor outside of Macy's office playing Tetris on her NCIS issued cell phone. She was in a tinsy bit of trouble with Macy. The Special Agent in Charge had caught Kate watching Army CID on her laptop instead of working. If Macy even remembered Kate was outside of her office, Kate's defense would be simple, 'The Bossman forgot to give me an assignment so I'm just waiting for one'.

"Talia is the plan." Macy said. Kate's ears perked up; maybe she'd get lucky and actually hear what was going on for once. "Sam, you will give Agents Gibbs and McGee a full briefing on the operation. Include Reko."

"Sure thing." Sam replied. He left the office followed by McGee and Jethro.

Kate got up to follow, but Jethro shook his head 'no' and Kate sank back down to the floor. She was staring at the tips of her Converse when her phone vibrated telling her she had a text message. Kate saw it was from McGee and opened it.

It read: 'Gibbs wants u 2 listen 2 mace and Callen. Report back 2 him after.'

Kate rolled her eyes before shooting a 'kk' back to McGee.

"Eighteen years," Callen was saying to Macy. "Would have made you a lieutenant in the Marine Corp Military Police. Gibbs was still a Gunny…"

"Don't go there." Macy snapped.

"Did you work a case together?" Callen asked playing dumb. He knew that Macy had investigated Jethro all those years ago, but Macy didn't know that Callen knew.

"Why do you want to know?" Macy asked with a sigh.

"Just looking out for my family." Callen said. Kate could just see the smirk on his face as he said that.

"G, you don't have any family." Macy pointed out and Kate winced. That was a low blow.

"That's cold, Mace." Callen said.

"But true." The blond replied.

"Gibbs is family." Callen told Macy. "You know that."

Macy didn't reply. As far as Macy knew, Gibbs was a fellow Marine Callen had served with and the younger man considered family. Macy didn't know that Callen had been almost adopted by the Gibbs family, which included the former Director of NCIS.

"Got any photographs in uniform?" Callen pressed on a lighter note.

"Yes." Macy answered. "And no, you can't see them."

"Okay," Callen said, he sounded like he had given up. "I'll just ask Gibbs what happened."

"Yeah, let me know if you do." Macy called to Callen's retreating back. "I want to be there to see him sit you on your ass."

Callen shook his head and closed the office door behind him. "Anybody ever tell you that eavesdropping isn't very nice?" Callen asked Kate.

"I think this guy from LA told me once or twice." Kate said teasingly. "But I just ignored him when he did."

Callen laughed and helped Kate up. Once the girl was on her feet Callen leaned over with a devious smile on his face and ruffled her hair.

"CALLEN!" Kate shrieked in protest. "It took me twenty minutes to get my hair right this morning!"

"God forbid I mess up Princess Kate's precious hair." Callen said condescendingly.

Kate responded by elbowing him in the gut and ran off towards MTAC.

"I'm gonna get you Gibson!" Callen cried as he took off after his baby sister.

Callen nearly flattened Kensi when he came barreling around a corner.

"Whoa there, G." Kensi said. "Where's the fire?"

"Gibson just elbowed me in the gut." Callen said. "And she took off in this direction before I could retaliate."

"Really?" Kensi asked surprised. "Kate doesn't seem like the type to start a fight unprovoked. What did you do Callen?"

"Me?" Callen asked as he feigned shock. "I didn't do…"

"You messed up my hair!" Kate growled out from behind Callen, making the older man jump.

"How did you do…? Never mind. It's gotta be genetic." Callen said as he turned to face Kate.

"Damn straight." Kate said as she threw an arm over his shoulders.

"You know each other?" Kensi asked curiously.

"Yep." Kate said. "We were foster siblings for, what was it?"

"Six months." Callen supplied fondly as he wrapped an arm around Kate's waist in a brotherly way.

"Then I got adopted and moved to Virginia." Kate said as she flicked the side of Callen's head.

"Ow." Callen said.

"Baby!" Kate said as she stuck her tongue out at him.

"So you lived with Callen?" Kensi asked Kate.

Kate just nodded as she wiggled out of Callen's arms as she saw a spark ignite in his eyes.

"I've got a ton of questions about a teenaged Callen!" Kensi said as she linked arms with Kate and dragged the younger woman back down the hall away from Callen.

Kate smirked evilly back over her shoulder at Callen and the NCIS Agent groaned. It was going to be a long day.

May 4, 2009

Kate tapped her fingers on the desk as she and Eric filtered through surveillance feed for Mattie Ray and Talia.

"Still waiting for the guest of honor." McGee commented.

"Bored?" Eric asked Kate.

"Out of my ever living mind!" she replied. "I'm an action-y field agent kinda girl and here I am playing She-McGee!"

"Hey! I heard that!" McGee told Kate.

"Good." Kate replied. "You were supposed to!" She juvenilely stuck her tongue out at McGee and almost fell out of her chair when her actions were reciprocated.

"Do I know you from somewhere?" Eric asked Kate as she turned back around.

"Uh, maybe." Kate said vaguely. Kate knew Eric recognized her voice from the phone call she made three years ago demanding to speak to Callen and Eric had been a pain in the ass about it.

"Vehicle entering the alley." Sam said over the com unit. "They're on the move."

Kate was up and out of her seat in a flash and next to McGee. She was debating whether to grab his hand or not when the Agent slid his hand into hers and gave hers a reassuring squeeze. Kate smiled in gratitude.

"McGee, go tight on Liam." Gibbs ordered.

"Zoom in on camera one, please." McGee said. Kate's smile grew even wider. One of the things that Kate like about Timmy was that he was always a gentleman, even under pressure.

"Wearing jeans and a sports coat." Kate relayed.

"He's carrying," McGee added as the picture became clearer. "Looks like a long barrel."

"It's a hit!" Callen cried.

Kate latched onto McGee's arm when the gunshots started. The NCIS Agents weren't visible on screen anymore. Kensi appeared on screen and dashed towards where Macy had been standing, and Kate watched s the brunette hauled Talia back to her car.

McGee felt Kate's grip relax as the both watched Gibbs haul Mike Renko, alias Mattie Ray an NCIS Agent, up and speak to each other. Gibbs had lost his ear wig in the scuffle so the conversation was muted.

"Where's Callen?" Kate asked worriedly when she couldn't see her brother on screen.

"I'm fine Katie." Callen's voice reassured her over their link. "We've got a motel key to a no-tell motel on the Strip I got off of Liam's body."

"Creepy much?" Kate asked causing Callen to chuckle.

Five minutes later Macy, Callen and Gibbs stormed the motel and found an empty room with four suitcases full of enough explosives to bring down a building, four blank passports, and suitcases full of guns.

Kate yawned and brought up some pictures of Liam that Abby had forwarded from DC. "Liam Patrick Coyle, former IRA Arms dealer. He smuggled money and guns into Northern Ireland in the '90's. After the peace treaty he went freelance. He's sold weapons from Chechnya to the Horn of Africa."

"Supplying terrorists." Jethro said.

"How come we've never heard of this guy?" McGee asked Kate.

"He's been living in New York. Fake name, fake job, fake life." She replied as she snapped the folder closed.

"It's called a legend." Nate said as he joined the group. Sam and Kensi were Callen's back up at the hotel. "It's a work coined by the Stasi, the East German Secret Police used it during the Cold War. Now, their idea was to create a cover so deep it could withstand any scrutiny."

Kate squirmed a little when Nate looked at her. 'He knows!' she thought to herself.

"Passports, documents, work papers, and even family histories." Nate said. "And none of it true. All a…a legend."

"So, back up a second." Kate said as she rounded on Nate. "You're saying that my older brother's posing as Liam, right now?"

Nate nodded.

"If Callen dies," Kate said as she turned to her father. "I'm lodging a complaint with SecNav."

"Duly noted." Gibbs said.

"Callen's your brother?" Eric asked.

"Foster brother." Kate snapped at the geek. "But I love him like a blood relative."

Eric shrugged. "Good for you guys."

Kate bit her lip anxiously as they watched 'Liam' open the door the room and admit a tall bearded man in a tan suit. Kate fought back a gasp as she recognized the man Callen had just admitted to the room. Kate has seen the other man in a photo Ziva had shown her from her time in Israel. The man was Mossad. Callen was in over his head.
