Background for Haunted By the Past:

Abby and McGee are dating secretly, Tony is in the beginnings of a relationship with a girl, Maddie, who is one of Ziva's friends (Ziva hooked them up). Gibbs is single; Ziva and G are still in a relationship. Nell and Eric have gone on one date but have yet to mention it to anyone. This story takes four months after The Assignment, it is early June.

Summary: Sequel to The Assignment, its Callen's turn to visit Ziva, but will their reunion be cut short when the couple bump into someone from the past?

Chapter 4: He Left

Washington D.C. Hotel Roomà 10:00 pm (DC) 7:00 pm (LA)

G was standing out on the balcony looking out over D.C. He couldn't believe the mess he had made. There was someone out there threatening Ziva, so he broke up with her not only breaking her heart but his as well. She was the only one who understood him, the only one who could really calm him down when he was mad at the world and he left her. He only prayed that when this was all over she would forgive him for the hurt he caused her. G shook his head and pulled out his phone, punched the number 4 and held it up to his ear.

"G?" his partner's voice said into the phone

"Hey Sam. What's going on?"

"Well Eric couldn't track the package that was sent here. Right now we have no idea who sent it any ideas?"

"It could be her father" G said. Eli David, the man who left his only daughter in Somalia to die. Somalia where she was beaten, raped and a number of other things.

"What does he have against you?"

"Everything. Maybe he thinks that I'm the reason she's staying here? I don't know. Look Sam I'm catching a flight back tomorrow morning"

"You sure?" Sam asked sounding confused.

"Yeah I'll see you then." Callen said and hung up. He really didn't want to have to explain to his friends that he broke up with Ziva. He knew what they would say. Sam would tell him he's an idiot. Kensi would worry about him. Nate would say it was something psychological about him wanting to be a loan wolf. And Hetty would say nothing. Just give him long looks and make him feel even worse than he already felt.

Washington D.C. Gibbs Houseà 5:30 am (DC) 2:30 am (LA)

Ziva woke up and found herself laying in a bed that wasn't hers. She froze, and then the memory came back to her. G breaking up with her, saying that their relationship wasn't working and her running to Gibbs house. She let out a sigh and slipped off the bed trying not to wake Gibbs who was still asleep. She put on some running clothes that she left at his house once and left for her normal 10 mile run before work.

When she got back she could smell the coffee in the kitchen and assumed that Gibbs was now awake.

"Morning Ziver" Gibbs called from the kitchen when he heard the front door slam.

"Morning" she replied.

"Wanna tell me what happened last night?" Gibbs asked. Ziva shook her head and stared pointedly at the ground.

"You know Abby and the others are going to ask when you come in this morning with out him."

"I'll just tell them he went to explore D.C." said Ziva.

"Come on Ziva, you know they won't believe that they are smarter than that."

"Fine" Ziva said annoyed. She grabbed a coffee cup poured herself some and then walked upstairs to get ready for work.

"Ziva" Gibbs said walking up the stairs after her.

"I don't want to talk about it Abba. It's painful enough as it is" she said her eyes welling up with tears just thinking about the fact that G was gone.

"I'm sorry Ziver." Gibbs said pulling her into a hug and giving her a kiss on the forehead.

They stayed like that for another minute or so before he let her go and let her change before they both headed off to work.

Washington D.C. NCIS Bullpen à 8:30 am (DC) 5:30 am (LA)

"Where's G!" Abby said running over to Ziva's desk.

"He's not here Abby" Ziva said calmly.

"Well I can see that…where is he? Bathroom? Gun range? Out getting you coffee?" Abby asked hopping from one foot to the other.

"No he is gone. Most likely already on his way back to L.A." Ziva said.

"WHAT!" Abby said loudly. "Why the hell-"

"Who Abby calm down where's the fire?" Tony asked walking into the bullpen McGee next to him.

"Apparently G left" Abby said looking at the two men and then back at Ziva. McGee and Tony both opened their mouths in shock.

"Why? Did he get a case or something?" McGee asked.

"Surely he would have said goodbye!" Abby said frowning

"Maybe he doesn't like you anymore Abbs" Tony said teasingly. Abby punched him in the shoulder looking furious

"Of course he likes me Tony!" Abby said still frowning. "Where is he Ziva?"

"He left Abby" Ziva said again.

"No really come on Ziva where is he?" Tony said smiling clearly thinking this was a joke.

"LOOK!" Ziva said loudly standing up and placing both her hands on her desk. They all jumped. "He is gone okay, that's that. I'm fine whatever can we please just get back to work"

The trio looked at each other and then silently headed to their perspective areas.

"We'll talk later" Abby said not about to let this go and then skipped out of the bullpen and headed back downstairs to 'Labby'.

Washington D.C. Airport à 8:30 am (DC) 5:30 am (LA)

G Callen was waiting for his plane to start boarding when he heard his phone ring. Crap. He thought as he looked at who it was.

"Heyyyyy Gibbs" G said trying to sound casual.

"What the hell is wrong with you G Callen." Gibbs barked into the phone, Callen winced.

"Look Gibbs, I'm sorry but I can't really say anything"

"Like hell G! Ziva comes over to my house last night and starts crying and says something about you two breaking up and you saying it wasn't worth it. I know that's bull Callen so what's going on"

"Is she okay?" G asked

"No she's not okay. She just lost the one person man who she was fully comfortable to be around. Who she could trust wholeheartedly, you know how hard that is for her."

"She has you, and Tony and McGee and Ducky."

"Not who she can fully trust, she can trust me because she is like a daughter to me and I a father to her you know that. But the rest of the team. Sure she trusts them to have her back in the field and stuff, but still she keeps things from them."

"Look Gibbs I'm sorry I don't know what I can say. It's done and I'm going home."

"Callen why did you break up with her?". G hesitated, this was Gibbs after all, a man who he saw as a father even though Gibbs was currently mad at him. But he understood why, Ziva was even closer to Gibbs than he is, but could he really trust Gibbs with the truth?

''Someone's after Ziva"

"Who" Gibbs demanded

"I don't know"

"Why the hell didn't you tell me this earlier if she is in danger—"

"She's not in danger. At least as long as I stay away from her."

"What do you mean?"

"Look I gotta go my plane is boarding, I'll call you when I land"

"G be careful okay? I can't lose my son." Gibbs said. G smiled and realized what it took for Gibbs to say that.

"Thanks dad, I'll talk to you later" G said before hanging up.

G sighed, this was going to be a long flight. He grabbed his bag and got on the plane. As the plane was flying right over D.C. all he could think about was Ziva. He hoped she would forgive him. He loved her more than anything in the world and he would do anything to make sure she was safe.
