The elevator dinged and Gibbs and Jason filed out, Abby and McGee following in the next elevator. Jason ran to his sister, Sadie, and took her into a hug.

"I'm so sorry," he mumbled into her shoulder.

"Come on, Jason, it's fine. I knew what was happening. I knew it wasn't your fault," Sadie soothed him. Jason pulled away, taking her face in his hands.

"I was so scared. I don't know what it was like for you. I just… I have to say sorry. It was my fault," Jason said.

Sadie, surprisingly, smiled. "Oh please, it wasn't your fault. And it would never have been."

Ziva shuffled in her feet, uncomfortable with this sibling affection she'd never been exposed to.

Gibbs walked past her, to his desk, saying, "He was forced into it."

"I guessed," Ziva answered.

"We will still need to ask both of you some questions," Gibbs said louder, getting the attention of the two teenagers.

"Sure," Jason said. "Anything." He paused, then turned to Ziva. "And thank you. For what you did for me. And Sadie."

"It's my job," Ziva answered. "Not that I did it too well today."

"Ziva," Gibbs warned. Ziva just nodded, moving to her desk and pulling up some files on the computer.

McGee began the questioning. Well, actually it was the girl.

"So do we know who did this?" she asked.

"That's what we wanted to ask you," McGee answered. "Jason, did you see the people who took you captive?"

"No," Jason answered. "I was asleep in my room. I felt people grab me then I fell unconscious. I don't really know what happened after that. I went in and out of consciousness for the next few hours. I do remember being in a truck though. I was tied up on some sort of… mat, I think. It's all the bit hazy."

"I understand," McGee said. "And after that?"

"Well, when I woke, there were three men. They all had black masks on and they were wearing the same black outfits. No brands or anything. Just plain."

"Okay," McGee nodded.

"I was hit, then they took me to the apartment. They sat me down and showed me a photo on the cell phone of Sadie. She was bound and gagged with blood on her face. They said they'd kill her if I didn't do exactly as they said."

"And Sadie? Where were you during this?" McGee asked her.

"I was in my room. It's at the opposite side of the house, so I didn't hear anything. When I woke up Jason was gone, but he usually goes for a run in the morning, so I wasn't worried. It was later that I got worried."

"Did anyone try to contact you?" McGee asked.

"No, I didn't get a single phone call all day. By that night I called you guys," she said.

"Why N.C.I.S? Not the police?"

"Well, Dad's with the Navy, and from previous experiences, the cops are useless most of the time."

"And your mother?"

"My mother's a drug addict. She took off when I was young," Jason answered.

"And mine's dead," Sadie answered.

"So you share the same father?" McGee clarified.

The kids nodded.

"And he lets you stay home by yourself when he's away?" McGee looked sceptical.

"He trusts us," Sadie told him.

"He thinks I can protect Sadie. He trained me," Jason said. But he didn't sound proud. He sounded as if he hated himself.

"You did," Sadie reassured him.

"Yeah, sure," Jason said sarcastically. "I almost got both of us killed."

"Oh, shut up," Sadie said, sounding angry.

Jason made a face at her.

McGee cleared his throat.

The kids turned their heads to him.

"What did your father train you in?" McGee asked.

"Martial arts mostly," Jason said.

"Is there anything else you can think of?" McGee questioned. "Any suspects? Anyone that would want to do this to your father or you? Perhaps any other information you can remember?"

Jason paused for a moment. "No, not really."

"Okay," McGee nodded.

Gibbs watched the kids as they were escorted away.

"Their story checks out," McGee told him. "One of the neighbours saw a truck pull out of their driveway at 0600, and a call was received at N.C.I.S last night at the time Sadie said she called."

"Their father is Sergent Charles Witlam," Ziva began. "He's a computer programmer who works with shipping navigation. Often goes on various ships with their crew for short periods. Never more than a month or so. He left on the Hital last Tuesday. He's just been informed as to what happened yesterday and we should be able to get him on video camera soon. He also wished to speak to his children."

"Not anytime soon," Gibbs answered.

"He just wants to know if his children are okay," Ziva reasoned.

"So tell him."

Ziva nodded.

"Abby is working on the cell phone Jason was using at the apartment," McGee said. "She should be ready soon."

Gibbs turned, moving away.

"What about DiNozzo's involvement?" McGee called out.

Gibbs froze.

"I want you to find out all you can about Kyle Lee," he told them.

This time Ziva froze.

"Kyle Lee?" McGee said, turning to her. "Who could that be?"

"At a guess, someone related to Lee."

"Ready?" Ziva asks, directing her query at Tony.

His gun is still pointed at McGee.

"We," Lee takes over, "are taking over the headquarters."

She begins to move down the steel steps.

"Vance is just upstairs," Gibbs says calmly.

"Nope. He's taking a call," Lee informs everyone. She keeps walking.

"Where?" Gibbs asks, his voice lowering.

"Out," Lee answered simply as she walked into the bullpens.

"It was you," McGee suddenly says. "You were the mole all along. Not Langer."

"I think we all worked that one out, McGee," Ziva says acidly, her eyes still on Tony.

"Sit," Lee tells Gibbs, pointing the gun at him, then the desk.

Gibbs didn't move.

Then, from the elevators and various doors, people began walking out, guns raised, all pointing at the team.

"Sit," Lee repeats. Gibbs does as he is told. The rest of the team follows suit. Abby, shaking, but quiet, sits in Tony's desk.

"Guns on the table," Tony tells them. Again, orders are followed.

Tony collects the guns.

"What are you doing Tony?" Gibbs asks.

"My job."
