Chapter One

Abby Scuito yawned and took a sip of her favourite drink "Caff-Pow!" She blinked a few times to wake up her eyes, and looked over at the skull clock on the wall. It was already 10:45pm. She yawned again and continued to analyse the evidence that Tony and McGee had brought up to her a couple of hours ago. She didn't hear the quiet footsteps while she was typing.

"No music tonight?" a voice chuckled from behind her.

Abby jumped. "Gibbs! Don't sneak up on me like that!" She laughed, softly.

"You didn't answer my question." Gibbs told her, pulling up a chair next to hers.

"I guess I just didn't feel like music tonight." She sighed. She started to type again.

"It's late, Abbs." Gibbs sighed, rubbing her shoulder affectionately.

"I know, Gibbs. I just gotta do this last blood analysis for you…"

"How long?"

Abby contemplated for a moment and then held up three of her pale fingers. Gibbs shook his head. He could tell that Abby was tired. She'd been working extra hours since they began another murder case a week ago, and Gibbs felt mean keeping her from her sleep.

"I'll get Ducky to drive you home, Abbs. McGee can finish up here."

Reluctantly, Abby let Gibbs lead her away from her computer and out of the lab. Gibbs switched off the lights as they left, and they both got into the elevator. As the doors closed, Abby's phone bleeped into life. She flipped it open and pressed it to her ear.

"Hello?"

"We have your sister." A robotic voice told her.

Abby gasped, tears welled in her eyes, "No, NO!" she sobbed.

Gibbs took the phone from her hands and put the call on loudspeaker. He flicked a button and shut down the elevator. One hand firmly around her shoulders, he nodded for Abby to carry on.

"Who is this?" She sobbed. "Where's Aimee? What've you done to her?"

"Your sister is safe, for now." Said the voice, "You will be sent a photo later. She is being held in a secure location until we get what we want."

"What? What do you want?" the tears wouldn't stop coming.

"You, Abigail Scuito. Await further instructions."

The caller hung up. Abby burst into tears and buried her head in Gibbs' jacket. Gibbs rubbed her back and leant his head on hers. Why would somebody do this? What did the caller mean when he said he wanted Abby? What was going on?

"Its gonna be okay, Abbs." He soothed her.

"Boss?" DiNozzo stood up as Gibbs entered the room, Abby firmly clinging on to his arm. She was still crying, hysterically. Tony, Tim and Ziva all ran towards their usually chirpy friend.

"McGee, Abby needs Ducky right now." Obeying his orders, Tim rushed down to autopsy for Doctor Mallard.

Tony sat Abby down on his desk. "Abbs?" he said, softly.

"T-they've got Aimee… She's the only one I got left… They cant kill her Tony… don't let them take her away from me… p-p-please…" she sobbed.

"I won't let them take Aimee away from you, Abby. C'mon." Tony pulled Abby into a tight embrace. The two were as close as blood. Tony was like a brother to her since her own brother passed away a few years ago.

"Oh, Abigail."

Ducky rushed into the room. Abby's tears began to slow, as her sense of all Guidance clutched her tightly in his arms. "Why, Ducky?" she whispered in his ear. Ducky couldn't answer. He could never compete with Gibbs, but he had still been a father to Abby from when she first came to NCIS. He knew how close Abby and Aimee were- although Aimee was three years older. He hated to see Abby so upset.

"Oh, Abigail." He repeated.

Abby had calmed in the next hour. Her and Ziva were sitting at Tony's desk, watching an episode of CSI on McGee's laptop. Ziva always liked to laugh at the obvious mishandling of weapons, and sometimes Abby joined in. McGee was watching intently, and Tony was ordering a pizza, as always. Gibbs and Ducky were standing by the window, observing the obvious down behaviour of the team.

"What are we going to do, Jethro?" Ducky asked, quietly.

"I really don't know, Duck. I've never seen Abby like this before. Aimee's her only member of family left. She loves her to bits. I don't know what she'd do if something happened to…" Gibbs shook his head.

"It wouldn't be good." Ducky agreed.

Gibbs dragged a hand through his grey hair. He was about to say something when Abby's phone rang. Ziva paused CSI and the whole room went silent. Gibbs nodded and Ziva put the phone on loudspeaker.

"I want to talk to Aimee." Abby's voice quavered.

"No." The robotic voice answered.

"I need to talk to her, or… or I'm not cooperating."

"Then your sister dies."

Tears were streaming down her cheeks, but Abby made no sound. Ziva held her hand, supporting her.

"What do you want from me?"

"I told you. We want you. We'll send you a photo of a location you know very well. We will meet you there tomorrow at 0500 hours. If you want your sister to live, you will come alone. If we see any of your NCIS buddies then we shoot you and Aimee." Once again, the caller hung up.

This time, Abby withheld the tears. She sat in between Gibbs and Ziva and waited for the text message. Finally, her phone bleeped.

"Will you look first? I don't want to see if Aimee's hurt or anything." She asked Gibbs, gently. He picked up the phone and opened the text message.
