A/N: Clark wasn't raised by the Kents! Instead he was adopted by the Gibbs. Takes place during Kill Ari. Tell me what you think.

"Well I suppose congratulations are in order."

Clark Gibbs grimaced as he heard the words. Typically he would have been grateful for a compliment from one of his oldest friends, but today wasn't a typical day. His best friend since he was eight years old had been shot, and now he had to deal with another one of his best friends, the young man having no doubt that he and his friend would butt heads.

"Usually maybe, but not today. Did you get the file I sent you?"

"I did. Are you certain?"

"I am."

"Then you must let one of my-"

"No. I'm sorry, but I can't do that."

"Ari is a Mossad-"

"He is a killer! He shot my oldest friend in cold blood! If you think for one minute that I am going to turn him over to you just so that you can let him go then you are very mistaken."

"I am not my father Clark. I know what Ari is, and you should know what I will do to men like him."

"I know that Ziva, but I also know that he is your half-brother. I know that you don't want to believe that he is guilty of this." He replied, attempting to keep his voice calm. Ziva sighed, and he knew that she was having as much trouble with this as he was. Neither of them liked being on opposite sides, but that was the price they paid when they accepted the Director's chairs of Mossad and NCIS respectively. You had to do what was needed for the job, and sometime's that meant friendship had to be ignored.

"You also know what Eli did to him." She replied softly, and Clark nodded even though she couldn't see it. He knew what Eli David had done to his son, what he had done to all three of his children. He had witnessed it first-hand, and as much as he wished he could have done something he hadn't been able to. It would have caused an international incident or as his father was fond of saying a major pissing match. Clark sat there for a moment in silent thought before he spoke.

"You're right, I do. That is the only reason why I am about to try to help you." He told her, the young woman grinning on the other side of the phone. Clark may say that was the only reason, but she knew better. He wasn't doing this for Ari or because of her father. No he was doing this for her.

"Here's the way this is going to work. I will allow you to send an officer, and I will assign them to work with one of our teams. I will order Ari Haswani to be brought in alive if at all possible. However, let me be perfectly clear about this Director...If anything happens to Chloe, Ari Haswani will be going back to Israel in a body bag, and I will personally put a bullet in his skull."

"I understand, and Clark...thank you."

"You're welcome. When this is over we should get together for drinks. It's been far too long since I've seen you."

"I know. I will buy the first round. The Mossad officer will be arriving tomorrow afternoon."

"That's fine. Shalom Ziva."

"Shalom Clark."

Clark sighed as he put down the phone, and walked out to the bullpen. This was not going to be fun.

"Agent Gibbs, I need you and your team in my office. Now." Gibbs head shot up as he heard his son's voice, knowing something was wrong; even after he had spent the last month as Director of NCIS Clark never called him Agent Gibbs. It was always just Gibbs or Dad. However, he didn't let any of his emotion show; instead he just nodded and walked up the stairs and into the Director's office, McGee, and Tony following behind.

"Take a seat."

"I'll stand if you don't mind." Gibbs replied, and Clark just glared before shrugging his shoulders as if telling his father to suit himself.

"I am ordering Ari Haswani to be brought in alive if at all possible. Also, there is a Mossad officer that will be arriving here tomorrow afternoon. Once that person gets here, they will be assigned to your team Agent Gibbs."

"Excuse me?"

"I just got off the phone with the Director of Mossad, and I agreed to allow them to help us catch Haswani."

"Are you out of your mind Probie? Your best friend is on a ventilator because of that son of a bitch and-"

"I know Tony. You also know that I'm not a probie anymore. Believe me, I don't like this anymore than you do, but if it helps improve relations with Mossad than that's what Chloe would want."

"I know." Tony replied, knowing that the younger man was right. Chloe would rather they work to make better friends with Mossad then just go after Haswani in a blind rage. He couldn't help but smile slightly as he thought of what his girlfriend would say if she was here. She'd tell him to get his head on straight and then she'd say some other things that he couldn't repeat in mixed company.

"Believe me, I know how much she means to you Tony. Chloe's the closest thing I have to a sister, and I already told Director David that if anything happened to Chloe I would put a bullet is Haswani myself. Now get out of here and go see Chloe. I'll be by as soon as I finish up here." He said, and Tony nodded before standing up and walking out, Tim following close behind. The door shut and Clark was left alone with his father who looked at him in silence before his face finally broke into a grin.

"So I see your feelings for Ziva haven't changed."

"What are you talking about?"

"No matter what you told DiNozzo I know why you allowed a Mossad officer to join my team, and it wasn't to make friends with Mossad. It was for her wasn't it? I remember when I was stationed over there. You and Ziva were damn near inseperable."

"Is it wrong what I did?" Clark asked, suddenly sounding unsure.

"Do you love Ziva?" Gibbs asked, and Clark smiled.

"Yes. I always have."

"Then you did the right thing. Although I still wish you had talked to me before putting a Mossad officer on my team."

"Rule eighteen. Better to ask forgiveness than permission." Clark replied with a grin, making his father glare at him.

"I taught you too well. Now if you'll excuse me Director, I'm going to check on Chloe."

"I'll be down in a few, got some paperwork I need to finish. The joys of being Director."

"Better you than me." Gibbs shot back before walking out of the office.

"Director, the Mossad officer has arrived." His assistant Janet said, poking her head into his office the next afternoon.

"Thank you Janet, please show them in." He replied, and she nodded giving him a smile as she did so. He grinned in return, rolling his eyes as she left. He had tried to convince her to call him Clark, but she wouldn't hear of it, saying that it was inappropriate for someone of his position.

"Good afternoon Director."

Clark looked up and smiled as he saw the agent standing there.

"Good afternoon...Director."
