This two-shot is kinda taken from the episode that Abby finds out she's adopted and has a brother by blood out there, I think it's called Enemies On The Hill. Anyways, this is GAbby angst in the beginning, but there might be a happy ending on the horizon.

Enjoy!

Shadows fill an empty heart

As love is fading

From all the things that we are

But are not saying

Can we see beyond the scars

And make it to the dawn?

"I-I don't even know who I am…"

Abby had ended up falling asleep in his arms that night, and Gibbs carefully carried her to the guest bedroom, tucking her in and kissing her forehead. He went downstairs to work on his boat and those words haunted him. Abby was Abby, there was no other explanation for it. Her past made her who she was, and now that past was a complete lie, at least in her eyes. Her brother wasn't really her brother by blood, and neither were her parents, her grandparents, none of them. And now that she had found her brother by blood, she didn't know what to do, and he didn't blame her. But it was killing him to know that she was second-guessing everything about herself.

Abby was Abby, and nothing could ever change that about her if he could help it.

In the morning, Gibbs woke to the smell of breakfast. He lifted his head and realized that he had fallen asleep in his boat, but he didn't know where the pillow and blanket came from. Then again, where was the breakfast smell coming from?

Oh. Abby.

He got to his feet and stretched, starting up the stairs and seeing Abby in the kitchen. "I'm surprised I had anything for you to use," He commented, and Abby jumped nearly a foot in the air, whipping around to see who was there. Gibbs put his hands up in surrender and said, "Whoa there Abbs, calm down, it's just me."

"You scared the crap out of me, Gibbs," Abby complained, turning back around with her hand to her heart.

"Who else were you expecting in this house?" He chuckled, and Abby just shook her head, flipping the stove off and sliding the eggs onto a plate. "You okay Abbs?" Gibbs placed his hands on her shoulders and literally felt the tension in her body.

"I'm fine," She said quietly, grabbing the plate and setting it on the table. He noticed it was set for one, along with his newspaper and glasses.

"Where's your plate?" He asked in confusion and she replied,

"I have to go back to my place, shower and change before I go in,"

Abby was past him and grabbing her coat before he could even blink. "Abby, wait," Gibbs called, jogging to catch up with her at the front door.

"What?" She asked, not looking at him.

"Abbs, look at me," He implored, gently touching her chin. She finally did and he saw the red-rimmed, tear-filled eyes she had been trying to hide from him. "You're not fine." Gibbs stated, and Abby stepped back from him.

"I was wrong to come here last night, okay? You made it quite clear what you wanted, and I didn't respect that and I'm sorry,"

Gibbs was startled and he demanded, "What are you talking about?"

"Oh come on, Gibbs, you can't tell me you don't remember," Abby scoffed, and Gibbs suddenly did remember what night Abby was talking about.

It had been a tough month for the pair of them, Gibbs and Abby. They had been dating quietly for a good few months, but the past few weeks had been tough, with Gibbs' first ex-wife coming back to town and then Abby's ex-boyfriend Mikel dropping by for a few visits. Tension was humming between the two of them, and even Tony noticed.

"Did you and Abby have a fight or something Boss?" Tony asked quietly before he went home, and Gibbs just looked at him.

"No." He said finally, when DiNozzo made it clear he wasn't backing down, not about Abby. Tony looked at him for a long time and finally nodded, saying,

"Night, Boss,"

As Tony walked away and into the elevator, Gibbs stopped writing his reports and sighed, dropping his head into his hands. When he and Abby ended up sleeping together, in every sense of the phrase, one night, the natural progression in his mind was to ask her out on a proper date. They had been dating for a while now, and she was the happiest thing in his life.

But lately, he had just begun to feel…different. He couldn't figure out why or for what reason, but he felt like he and Abby were drifting apart. Gibbs had always known she was out of his league, but for some strange reason she was with him. It never made sense in his mind, and now it was falling apart. Maybe she had finally figured out that he wasn't good enough for her, or maybe she had found someone that was more to her taste, more to her liking.

It never made sense for her to love him, and yet she claimed she did, and still does.

Without really realizing it, he got up and headed down to Abby's lab. When he stepped through the doorway she turned around, beaming at him. "I'm almost done, Gibbs, just give me a few minutes,"

Then she caught sight of his face and frowned. "What's wrong?"

"I-I'm not sure," He said hesitantly, and she raised her eyebrows.

"Well, just spit it out,"

"Abby…what're we doing?" He finally asked, and she looked confused.

"You mean we as in our relationship?" At his nod, she said, "I thought we were dating, were you under a different impression?"

"No, I mean, I guess I'm asking why."

"You're asking why we're in a relationship? I'd say you answered that question when you asked me out six months ago," Abby said quietly, and Gibbs opened his mouth, and then closed it.

"Abbs, I think, I think maybe we need to take a break, or something,"

"A break," She repeated flatly, and he kept going, almost desperate to get his point across.

"I don't think you really know what you want, and I think maybe a break will help you. Maybe what we're doing isn't the right thing, for you," He was close to babbling and he knew it.

"For me." She repeated, and Gibbs began to feel a little scared by the look on her face and in her eyes.

"There are no breaks in relationships!" Abby yelled, her hands fisted at her sides. Gibbs took a step back as she raged at him, saying, "You keep saying a break will help me, maybe this isn't right for me, well you want to know what I think? I think you are the one who's scared about being in a relationship at all! And perhaps you're right, perhaps this isn't the right thing, if you're second guessing everything we've ever had together then maybe this isn't right."

"I know it never made sense for you to love me, Abby, and I think you need to rethink that,"

And with that statement, Abby blew up, but in a silent and deadly way. She froze, her eyes cold as ice. "Leroy Jethro Gibbs, get your ass out of my lab."

"Abby…" He started to say, his brows furrowed.

"GET OUT!" She screamed, and Gibbs turned and strode out before she could throw something at him. The door slammed behind him and he could hear her sobbing as he tried to figure out what the hell had just happened.

"Abbs…" He said quietly, and Abby just shook her head.

"Don't worry about it, Gibbs. You said what you felt; I can't fault you for that."

With that she stepped outside towards her car, and Gibbs watched her drive away, thinking to himself that he had just seriously messed up what could be his only chance to make things right with Abby.

Truth be told, he had done a lot of thinking since that night. He realized that he needed to stop questioning everything he had with Abby and just accept it, and he wished that he had thought about that before he went and blew everything to hell with her.

Change the colors of the sky

And open up to

The ways you made me feel alive

The ways I loved you

All the things that never died

To make it through the night

Love will find you

Gibbs dragged himself into NCIS that morning and almost immediately Tony came up to him, demanding, "What did you do?"

"What are you talking about DiNozzo?" Gibbs snapped, and Ziva came up, saying dangerously,

"What did you do to Abby?"

"I didn't do anything to her," Gibbs said roughly, shoving past them. McGee suddenly appeared in front of him, holding up a piece of paper.

"Then why did she resign from NCIS?"

Gibbs dropped his coffee mug and snatched the paper out of McGee's hands. He skimmed most of the words, and then he read 'I cannot continue to work at NCIS for personal and private reasons'. He noticed Abby's signature at the bottom and he turned on his heel and stalked up to Vance's office.

He just barged right past Vance's secretary and into his office, saying, "You can't accept this."

"Accept what?" Vance asked, and Gibbs slammed his hands down on Vance's desk, saying angrily,

"You know damn well what."

"Gibbs, Abby came to me this morning and handed it to me personally. There was nothing I could do." Vance stated, getting to his feet.

"Don't tell me you filed it."

"What else could I do?" Vance said evenly, and Gibbs swore before storming out of the room. He was an angry whirlwind all the way down to autopsy, and he strode in, looking for Ducky.

"Looking for Abigail?" Ducky asked, and Gibbs turned around, facing the doctor and asked,

"Duck, where'd she go?"

"You don't deserve to know, Jethro. You broke that poor girl's heart, and for that, I cannot forgive you."

"She deserved better, Duck! She still does," Gibbs said miserably, leaning against the wall.

"When you told her that you thought the two of you needed a break, she thought it was her fault. She's spent the past month blaming herself, trying to figure out what it was that she did wrong. When you said it didn't make sense for her to love you, she took it as a gentle letdown that you didn't love her. She doesn't understand that you think yourself too inferior for her because she sees you as too good for her." Ducky explained patiently, and Gibbs groaned.

"God I screwed this up,"

"Yes you did. And now you're going to make it right." Ducky said matter-of-factly, and handed him a plane ticket.

What about now?

What about today?

What if you're making me

All that I was meant to be?

What if our love

Never went away?

What if it's lost behind

Words we could never find?
Baby before it's too late

What about now?

"What…?" Gibbs said, glancing down at the ticket in his hands.

"Your flight leaves in a few hours, I'd suggest getting to the airport ASAP because the security checks these days take forever. And don't you dare come home without our Abigail." Ducky instructed, and all but shoved Gibbs out of autopsy.

In the elevator, Gibbs read the ticket information and discovered it was taking him to New Orleans, Abby's birthplace. He nearly smacked the back of his own head because it was so obvious, he wondered why he didn't think of it earlier.

While Gibbs was boarding his plane, Abby was knocking on her brother's door…well her adopted brother's door. He opened it and grinned, saying, "Abby!" He hugged her tightly, and Abby fought back tears.

"Hey Luka," She said affectionately, but he heard the pain in her voice.

"What's wrong?" He asked in concern, leading her inside his apartment.

"It's just, there was this guy at church who needed a kidney transplant and I went to get tested and I'm a match, but so is this other guy and the lady that tested us asked me if I knew my brother was a match too and I was confused because I didn't think you knew this guy so that's when I called you and asked you about it and then I went back to the lady and she wouldn't tell me anything more but I tested the hair from my locket, you know, Mom's hair and I tried to match it to my DNA and it doesn't fit. I'm not her daughter, Luka, I'm adopted. I'm not your sister. I'm some stranger's sister."

So this is the end of the first chapter, there's gonna be one more since this is a two-shot, and the song I'm using is "What About Now" by Daughtry, but I kinda like the version Westlife did better. Either way, it's the same song, and it's a great song. So will Gibbs get to Abby in time to change her mind? Or will someone else do that for him? Thanks for reading and I hope you like this story!
