A/N: Here it is, the last chapter.

The agents looked around. They didn't really understand what was happening. Where did these lines come from? Where they dangerous? Would they trigger something?

"Okay, everybody stay still," Callen spoke. "Eric, Jenny, can you hear me?"

"Yeah we hear you G," Jenny replied.

"Okay, we are trapped somehow. Out of nowhere these lines came up, forming a grid. They look like laser beams. We might trigger something if we move."

"Okay, we'll check if we can find something on the warehouse. Can you pinpoint where the signal is coming from or what triggered it?"

"I'm not sure. We were just looking around to see if we could find something. Nobody is in the warehouse. Maybe we triggered it or maybe someone remotely triggered it, I don't know."

"Okay, keep still till we know more."

"Will do."

Eric and Jenny quickly went to work to see if they could find out where that grid came from or who triggered it. If it was activated remotely there should be some sort of electronical pulse or something they could track.

The agents didn't have much wiggle room so they had to be very still or they would trigger the lasers.

After about an hour of looking Eric and Jenny went downstairs to Hetty's office.

"Hetty, the agents are still in the grid. We can't find anything from here to shut it down or where it's coming from. We need to go on site," Jenny spoke.

"Are you sure you can't do it from here Mrs. Callen?" Hetty asked.

"We've tried Hetty, we can't. If we go on site we might be able to find the source."

"Alright, take your gun with you Mrs. Callen."

"Of course."

They grabbed their gear and left for the warehouse. Jenny pulled her gun out of its holster and checked the surroundings as they made their way to the warehouse. When she was sure it was clear she put her gun back in the holster and they made their way inside. They stopped at the edge of the warehouse, just before they would step into the grid.

"Hey guys," Jenny greeted them.

"Jenny? Eric?" Callen asked surprised. "What are you doing here?"

"Well, we couldn't find anything to shut this down or where it came from so we asked Hetty if we could come onsite," Jenny answered.

"Be careful, we don't what these things do."

"We will be G."

Eric and Jenny grabbed their equipment and started working. They configured the tablet so they got the grid on that. Jenny was busy looking for the point of origin as Eric was working on a way to shut the grid down.

Jenny found that the grid was coming from a box inside the warehouse, unfortunately the grid was in the middle of the right wall. Someone needed to get to that box, that was probably the only way to shut it down and find out who or what triggered it. None of the agents were in that area. Jenny and Eric were closest to that from the front door.

"Jen, what's going on?" Callen asked when he noticed that his wife was trying to figure something out.

"I've gotta get to that box," Jenny answered as she pointed to the box.

"There's no way you can get through all these lines."

"Maybe I can," Nell interjected. "I'm the smallest one here, I can get through the lines."

"You're way further from it than I am," Jenny replied.

"But I'm smaller than you, I can do this."

"Alright, we'll guide you."

Carefully Nell took her rifle and vest off. She secured her hair so her ponytail wasn't wiggling around. Nell looked to see what was the best path to take. Unfortunately the lines didn't have the same height which made it harder. The other agents watched as Nell attempted to get through the lines. Near her was one near the ground and one just above her. Nell lifted her legs to get over the line above the ground and was careful not to hit the one above her. She squirmed her way through the grid, careful not to hit any lines. Some parts were very tricky, she had to go down on the floor to get underneath it.

"Okay Nell, watched it, you have one right in front of you as you come up," Callen warned her. She was right next to him.

Nell was now standing in front of Callen. She had to go around Callen to get to the box. She looked around but there was no way she could make it around Callen. The lines around Callen were too closely together. They only way was through Callen but there was no way two people would fit in that little box where Callen was standing.

"Damn, I can't go any further. There's no way around Callen," Nell spoke.

Callen looked to see if he could maybe move a bit so Nell could get through but he didn't have much wiggle room and there was no way Nell would fit in the box with him.

"Jenny, you're gonna have to go through after all. I can't get through."

Jenny took her jacket off and tied her hair in a bun.

"Be careful partner," Eric spoke to her.

"I've got this," Jenny replied and took a deep breath.

"Take it easy Jen, take your time," Callen told her.

"I'll be fine G."

Jenny stepped into the building, careful to avoid the lines. She looked to see what would be the best path. Callen watched anxiously as his wife maneuvered through the grid but on the other hand it was kinda hot to see her squirm like that.

"Watch the line above you," Callen called.

Jenny carefully went through, she only needed one more box before she reached the box on the wall. She bent down to go underneath the line as she lifted her feet up to not hit the line near the ground. Carefully she got up and shifted a few steps to the left and then 'limbo-ed' underneath the last line. She stood straight and faced the box. She had some tools on her body. She opened the box and looked at its contents. Carefully she fished a tool out of her back pocket. She hooked it up to some kind of electric panel she found inside the box.

"Eric, are you getting it?" Jenny asked.

Eric looked at his tablet and typed a few keys. "Yeah I've got it. But we're gonna have to disable this together."

Jenny and Eric looked at the panel to see which button or switch they had to push.

"Alright Eric, you ready?"

"Yeah."

"On three, one, two, three," Jenny spoke and they hit the switch together.

The grid powered down and the lines disappeared. They all let out a relieved breath. The agents were glad they could move again. Now that the grid was down they started looking through the warehouse as Jenny and Eric tried to figure out where the signal was coming from and who powered it up.

"Guys, we've got a location on where the source came from," Jenny called after a while.

"Send it to my phone," Callen spoke. "We'll check it out."

Eric typed a few keys on his tablet. "Already on your phones."

"Thanks." Callen turned to the others. "Nell, Clara, come with us, we will check this out. Kensi, Deeks, see what you guys can find here."

Callen and Sam took their gear and got into Sam's car as Nell and Clara got in Clara's car. Sam and Clara drove them to the address that was on their phones. It was a house in Central LA. It was a house on the corner of the street. Sam parked the car around the corner a few houses down and Clara parked right behind them. They took their rifles and approached the house.

"Clara, Nell, go around back," Callen spoke.

Clara and Nell crept down the side of the house, careful to not being spotted from the windows.

"We're in position," Clara spoke a little later through the com.

"Alright, breach on my count. Three, two, one."

Weapons hot they breached the house.

"Federal agents!" They yelled.

The people in the house didn't know what was happening. Terrified they put their arms in the air. Callen and Nell kept their guns at them as Sam and Clara went to cuff them.

"What's going on? What's the meaning of this?" The man asked, demanding to know what was going on.

"Don't play dumb, we know you set the trap in the warehouse," Callen replied.

"Trap? What warehouse?"

"We're really gonna play that game?" Callen asked, getting slightly annoyed.

"I'm not playing any game. I have no idea what you're talking about. I've been here all morning."

Suddenly they heard some rumbling from the back of the house.

"We've got a runner," Clara spoke and she was hot on his heels with Callen right behind her.

"Who else was in the house?" Sam asked.

"Juan, my son, please, he has nothing to do with this."

Clara chased him down. Juan was running through the alley behind the house. He took a side street. Clara kept running after him but Callen ran straight ahead, hoping to cut him off. Callen rounded the corner and Juan was running towards him. When he saw Callen he screeched to a halt. He wanted to turn around but there was Clara already.

"Federal agents! It's over," Callen yelled at him, raising his SIG.

Reluctantly Juan got down on his knees with his hands behind his head. Clara walked up to him and cuffed him. In cuffs they took him back to the house.

"Juan, ¿qué hiciste? Juan, ¿qué está pasando? Juan, digame![Juan, what's going on? Juan, what happened? Juan, tell me!]" The man spoke to his son.

Juan kept quiet as Clara took him through the house and outside.

"Please, my son wouldn't hurt anyone. Please, it's all a mistake," the man pleaded with Callen.

"He ran from us, clearly he has something to hide. The signal in the warehouse, we tracked it to this house. Our agents are gonna have to look through his belongings."

"My son is a good kid, he's a bit too himself but he wouldn't hurt anyone."

"That may be sir but we have to follow the evidence." Callen turned to Clara and Nell. "Search the house, she what you can come up with."

"Will do," Nell replied.

Callen and Sam took Juan to the boatshed as Clara and Nell stayed behind at the house. They put their rifles and vests in the car and gloved up before looking through the house.

"I'm sorry but we have to do this," Clara spoke to the family. "Please stay out of our way so we can look. I know this is difficult but we're gonna have to search the house."

"Just be careful with the stuff," the woman spoke.

"Of course ma'am."

The family watched as Clara and Nell went through the house.

Callen and Sam put Juan in the interrogation room and Callen sat down opposite from him.

"Why did you run Juan?" Callen asked.

"I thought you came there to kill me."

"We said we were federal agents."

"In Colombia that's not necessary a good thing."

"Why did you do it Juan?"

"I'm good with computers. Someone found me and asked me to do stuff for them. They said they would hurt my family if I didn't do as they asked."

"What did they ask of you?"

"They wanted me to hack into this drone and use it to blow up this container."

"Who asked you? Where they Colombians?"

"Yes they were. They said they were part of some gang."

"Did you happen to hear what was in the container or why they wanted it gone?"

"I was told not to ask questions but I did hear them say something about taking down another gang. What was in the container?"

"Weapons that were stolen from the military base here in California. There were five crates in that container, headed for Colombia."

"Probably to supply the cartels there. Maybe they were rivals. I don't know. I didn't ask. They contacted me just before you got to my home. They told me that some agents were in the warehouse we used to hack into the drone and they wanted me to activate the grid. They asked me to simulate a grid and put it in the box in case someone would come looking."

"How did they contact you?"

"They send me an email with pictures of my family. They said they would die if I didn't help them. I've never seen them face to face. After the email there were also a few calls but never face to face."

Callen and Sam got up to leave.

"Wait, what about my family now, if they know I'm caught they might get hurt."

"We'll keep an eye on them," Callen spoke before he and Sam left the room. Callen picked up the phone and called Clara.

"Yeah dad," Clara answered the phone.

"Look for a laptop or phone. Juan said they contacted him via email and calls."

"Alright got it."

Callen hung up the phone and called Eric and Jenny via the screen, they were back in OPS already.

"Yeah Callen," Eric spoke as his face popped up on the screen.

"Hey Eric, Jen, check for Juan's email account and phone records. He said that that's how they contacted him. It looks like we're dealing with a rival cartel. Juan said that someone hired him to hack into the drone and blow up the container."

"Alright got it, we'll see what we can find," Jenny responded and cut the call.

It was about two hours later when they had a lead. Jenny and Eric had found the group that had hired Juan. The agents geared up and went to his warehouse. As soon as they stepped into the building gunfire erupted. The agents duck behind the first thing they could find and fired back whenever they could. After a while all the bad guys were down, most of them were dead. Only two were still alive. They were taken to the hospital when the EMT's showed up. Callen hoped they could question them later. This was just one part of their case. They still needed to find the other gang and get the missing weapons back before they would be send to Colombia. Fortunately one of the guys was only mildly hurt so Kensi and Deeks went to the hospital to question him. He was a bit low on the food chain so with some pressure he talked, giving Kensi and Deeks the location of the other gang. The agents went to the address, with the back-up of some other agents they stormed the place. Again there was heavy gunfire. Luckily they had taken enough bullets with them but the cartel was heavily armed as well.

"Grenade!" Sam yelled as a grenade came their way.

He quickly picked it up and threw it back. The grenade exploded in the middle of the group, killing several. After what seemed like an eternity all the bad guys were down. With their rifles raised they went to check them.

"Found the missing crates," Kensi yelled from the back of the warehouse.

They wrapped up at the scene and the crates were shipped back to Pendleton, everything was accounted for. The agents went back to the office and finished their paperwork.

/Time Jump/

Tomorrow was Jamie's graduation day. He was graduating MIT with flying colors. Callen, Jenny and Clara had gotten a day off from work so they could fly out to Boston. Jamie's graduation day was on a Friday. It wasn't till the afternoon so Callen, Jenny and Clara flew to Boston after work. Their flight left LAX around 9pm, local time. They were at Boston airport just before 6am, local time. They had managed to get some sleep on the flight. They grabbed their carry-ons, they didn't have any luggage. They walked out and went to pick up their rental car. Callen drove them to The Kendall Hotel. It was close to MIT, it was only a five minute walk. They were staying in a Deluxe Double room with two queen beds. They decided to get a little bit more sleep. They woke up just before noon and got ready to go to MIT.

"Hey Jamie," Jenny called when she saw her son.

Jamie walked up to them and gave them each a hug.

"So, final day of school," Callen remarked.

"Yeah I'm glad it's finally done and I'm glad to be going home. It's been nice here but I miss you guys and the LA weather."

Together they had some lunch before getting ready. Jamie went to his classmates and Callen, Jenny and Clara walked to the area where the ceremony was being held. Just as they walked onto the lawn they bumped into Hetty and Sam.

"Hey guys," Callen greeted them. "What are you doing here?"

"We came to see Jamie graduate," Sam responded.

"Thanks guys, thanks for being here."

"Of course."

They all took their seats and waited for the ceremony to start. Callen had the video camera and Jenny had the photo camera. When it was almost Jamie's turn Callen started recording. Jenny took her camera and took some picture of Jamie up on the stage. They were both proud of their little boy. When everyone got their diploma the class president stepped up and spoke a few words.

"Class, we did it!" Where his last words and everyone threw their hat in the air.

A little later Jamie stepped up to his parents.

"Congratulations son," Jenny told him and gave him a hug.

Callen and Clara congratulated him too.

"Hey uncle Sam," Jamie spoke surprised when he saw Sam. "Thanks for coming."

"Of course. Congratulations."

"Thank you."

"Congratulations Mr. Callen," Hetty spoke.

"Thank you Ms. Lange."

"Very well done. I've reviewed your grades. You really did amazing."

"Thank you."

"I don't know what you want to do now that you've graduated but after the summer some changes are gonna take place at the OSP. I would like you to considering this job opening," Hetty said as she handed him a red folder.

Jamie took the folder and opened it. He looked at its contents and saw it was a job opening for the positions his mother now had.

"Thank you Hetty, I'm very honored. But I'm not sure I'm ready for this just yet."

"Of course you are. You have gotten good grates and you've proved that you can handle it. Of course you have to go some courses before you can join but we would be lucky to have you."

"I will think about it. Thank you for the offer."

"Of course."

They enjoyed the party before going back to their hotel. Hetty and Sam went back home the following day. Callen, Jenny and Clara left on Sunday. Now that Jamie was done with school all his stuff from his dorm room had to be moved. They rented a truck to transport his stuff back to LA. Jenny went to return the rental car to the airport, Clara went with her in Jamie's car so Jenny could get back to the dorm room. Once everything was in the truck or car everyone got in. Callen rode in the truck and Jamie, Jenny and Clara drove home in Jamie's car. They made a few stops along the way before making a stop for the day in Pittsburgh. They booked some rooms in a motel. After breakfast the next day they continued their way home. Their night stop was in St. Louis. After that they stopped for the night in Oklahoma City, Carlsbad and Phoenix. From there they drove straight home. For now Jamie was coming back home until he got a job so he could buy an apartment for himself.

…..

Over the next few days Jamie thought about the job offer Hetty gave him. It was always his dream job to work at NCIS and do the same work as his mother.

"Mom, if this is a job opening for you job, what are you gonna do?" Jamie asked Jenny during dinner.

"Well, like Hetty said there will be some changes. Your dad is becoming the new operations manager and I'm gonna be the new assistant-director of NCIS, overseeing the west coast operations. So that leaves a spot in the OPS center."

"Ah okay. What do I have to do more to apply there?"

"Well you have to go to FLETC to complete some courses and a few courses within NCIS."

"Do you think I can do it?"

"Of course you can. You're very smart. Smarter than me sometimes, you can do it."

"Would you two be okay if I came to work there?"

"Your sister is already working there," Callen spoke. "Why not our son too. We'll make it a family company," Callen joked.

"Alright, I'll take it."

…

When all the necessary paperwork was filled out and Jamie had had some down time after school he was on his way to the NCIS headquarters. After being accepted into NCIS he was on his way to FLETC. He went to Glynco as well. He took the courses CNITP, CESP, CETP, DEASTP, IATP, RECVR, SCERS and WTAG. In total it were sixty five training days.

When those sixty five training days were up Jamie reported back to the NCIS headquarters in Washington. They were very pleased with Jamie's results and he could report to the OSP the next day.

…

Callen and Jenny were setting up everything in their new office when Jamie walked in. They were sharing Hetty's old office.

"Good morning dad, mom," Jamie spoke as he walked into the office.

"Good morning Jamie, welcome to NCIS. It's good to have you here. I've heard about the results at Glynco. I'm very proud of you."

"Thanks dad."

"You'll do just fine here."

"Come on Jamie, I'll take you upstairs," Jenny spoke.

Jenny took Jamie upstairs to OPS.

"Hey Eric," Jenny spoke as she walked in.

"Hey Jenny, hey Jamie."

"Eric, this is your new partner Jamie."

"Hey Jamie, welcome to NCIS," Eric spoke.

"Thanks. It's good to be here."

"Well, I'll leave you two at it. Jamie, Eric will show you the way around the system and such. I'll be right downstairs if you need me."

Jenny left the OPS and went downstairs.

Life at the OSP was changing now. Jenny was now assistant-director instead of Owen Granger and Callen had taken over Hetty's position. Sam was now working at Pendleton, training new SEALS. Kensi and Deeks were senior agents now with Kensi being the team leader and Clara and Nell were the junior agents and up in OPS were Eric and Jamie now.

The end. Thank you for reading and reviewing. Hope you liked it.
