Gibbs enters the lab, with Abby's morning caf-pow.
"What do you have for me?"
"I just got the evidence ten minutes ago."
"Why is it so quiet in here? No music?"
"I am trying to de-clutter my mind."
Gibbs grows suspicious. He scowls at her.
"It's a secret," she warns.
Gibbs hears a noise coming from her office. He walks past her. She runs in front of him, and blocks the open doorway.
"Don't go in there," she begs.
"Abs, move," he insists.
She crosses her arms in dissatisfaction, and steps aside. He steps into her office, and retrieves something. She is standing by her computer when he returns.
"I found this in your office Abby," he holds it up for her to see.
"How did that get there?" she feigns surprise.
"Let me ask him," Gibbs looks at the sleeping baby. He kisses his forehead, "I need you to wake up. I have something very important to ask." Matthew's eyes pop open, "Tell me how did you find your way to Abby's lab? Oh that's right you can't walk, or talk," he shifts his focus back onto Abby.
"He called me this morning, and said he wanted to hang out with me," Abby smiles.
"He called?"
"Someone called on his behalf," Abby clarifies.
"Don't let Vance find out," he warns.
"She promised it would only be for a day or two. I don't mind. I enjoy watching him. And I will not let him interfere with my work. He's a lot like you, you know. He's very quiet."
"He's a baby," Jethro points out.
Abby looks at the baby, "A very cute one."
"He takes after Ziva."
"He definitely has your personality. He's all quiet, and stoic."
"He's something," Gibbs agrees as he holds his son.
"Gibbs?"
"Yeah Abs?"
"You have work to do. You need to leave baby Gibbs with me."
He passes the baby to her. "You have work to do too."
"I only need one hand," she tells him.
Gibbs goes into her office. He pulls the playpen into the lab, next to the computer, but out of the way.
"You want me to keep a closer eye on him?"
"You don't have to hide him. I know that he's here."
"Ok," she agrees.
He heads for the door. In the doorway he turns and pivots.
"Abby why did you call him baby Gibbs?"
She stares at the baby. She doesn't look at Gibbs when she answers, "He just reminds me of you, that's all."
"You told me yesterday that his hair in the picture you had reminded you of Ziva, but you didn't call him baby David. You called him Matthew. You usually call him Matthew."
"Sorry."
"Don't apologize, explain."
She turns and looks at him, with a smile, "I would love to, but I have work to do," she begins typing.
"Abby..." he starts.
"Take it up with your baby mama," Abby insists.
"Baby mama?" He furrows his brow.
"Take it up with Ziva," she clarifies.
He gets onto the elevator. When he reaches the squad room he finds his team all diligently working at their desks. He stops at Tony's desk. Tony doesn't look up.
"Yeah Boss?"
"I need you to tell me something," Gibbs demands.
"Anything," he agrees staring at his computer screen.
"Do you know where Matthew is?"
"Let me put it this way boss, you are the president, and he is the football, it is my job to know where he is at all times."
"So you know where he is, right now?"
"I've got eyes on him right now," DiNozzo confirms.
"Eyes?"
"Nanny Cam," DiNozzo replies.
"Nanny cam, or Abby cam?" Gibbs quizzes.
"You've been downstairs?"
"Yep," he nods. Without turning around he scolds, "Ziva sit back down. Do not try to escape."
She returns to her seat. He turns to Ziva. She looks up at him.
"You're angry that I left him with Abby? I didn't have a choice. I will find him a Nanny, tomorrow," she promises.
"That isn't why he's irritated," Tim reveals.
"How would you know?" Tony questions.
"Just got a text from Abby. Ziva, she says that she is sorry, it was an accident," Tim replies.
Ziva jumps to conclusions, "Accident? What happened? Did she drop him?"
"No. Ziva calm yourself, probie is probably referring to Abby's inability to lie to Gibbs. She probably told him the thing, you know the one that you didn't tell him."
Gibbs spins around. He smacks Tony on the back of the head. He squints, "And what would that be DiNozzo?"
"Ziva was just getting ready to answer that."
"I know she was," Gibbs turns around and faces Ziva once again.
"What would you like me to tell you? If you are wondering about the case, I have learned that our dead Petty officer was in serious debt. He owed on credit cards, a house, two cars, a boat, he even owed his mother-in-law money."
"That is good to know, but not what I wanted to hear about."
"What would you like to hear about?"
"Matthew," he reveals.
"Would you like a status update? It seems Abby has just changed him, and things are coming out just the way that they are supposed to."
"Ziva shouldn't you have had a brit for Matthew?"
"Tony I am not that traditional. I am also more comfortable with the sterile technique used in the hospital."
"So you had it done in the hospital?" Tony clarifies.
"Yes," she nods.
"DiNozzo is there a reason you change the subject to circumcision?" Gibbs wonders.
"I wanted to know."
"Do you have Matthew's birth certificate?"
"Not with me, why?"
"What is the name on his birth certificate?" Gibbs grills.
"Matthew Isaac."
"I know that."
"So then why are you interrogating her?" Tim quizzes.
"Because McGee, Abby just called Matthew baby Gibbs," Gibbs retorts.
"He is your son," Tony points out.
"Abby has never called him baby David, he is Ziva's son too."
"He probably just reminds Abby of you," Tony tries to cover.
"Ziver!" he smacks her desk.
"I considered giving him your last name, but at the last minute I changed my mind."
"I did not know that."
"I should have discussed it with you."
"Ya, think? You discussed it with everyone but me."
"I am sorry."
"What is Hannah's last name?" Tony inquires.
"David. What else would it be? Would you prefer that I used the last name of a dead man that I do not know, Tony?"
Gibbs walks away from Ziva, to his own desk, allowing Tony and Ziva to finish their conversation.
Tony shrugs, "I guess not."
"Have you spoken to her today?" she probes.
"No. Why would I?"
"You talk to her everyday during lunch."
"How do you know?"
"Tony I am her mother, I know everything."
"You also pay her cell phone bill," McGee reveals her secret.
"That is also true," Ziva nods.
"No I have not spoken to her. She's probably just busy. I wouldn't worry about it."
"I'm sure that you are right."
"Didn't she have a math test to study for?" Tony recalls.
"Yes," Ziva acknowledges.
"I should text her, tell her good luck."
"I'm sure that she would appreciate that."
"Did she ask you to chaperone her class trip?" Tony wonders.
"No. She asked you instead."
"Why?"
"She is afraid that I will scare her classmates."
"Can we get back to work now?" Gibbs demands.
