Thanks to my beta Kristen! There's an epilogue after this... And don't say I don't give you fluff.

Chapter 11: Dada

Ziva David glared at the man sitting opposite her. This time, Gibbs had allowed her to conduct the Interrogation, although he had warned her not to injure the man. He did not want to case thrown out of court on a technicality.

Although the way Gibbs and Jenny were stalking around, Tucker was not likely to make it to court. No one threatened the twins and got away with it. With the possible exception of Lily, but she did not count because she did not mean it. It was strangely surprising that Lily had not demanded to perform the interrogation herself. After all, she had put the twins in harm's way and surely she felt she had to redeem herself?

Unless she refused to accept that she had done anything wrong at all, in which case she was more likely to just stab Tucker when she next ran into him. The latter explanation seemed far more probable. If she could get Tucker to crack, Lily would intervene before he made it to the cells. The man would be looking over his shoulder for years.

She glared at him again. How could he kill such innocent children? Abby had managed to pull his fingerprints from the vials Lily had stolen and they should not have been present. Tucker was not even supposed to be on duty at the time of the incident, which meant he would have to have a very good reason ready for his lawyer. If he ever got a lawyer. Gibbs was trying to come up with some way to tie him to terrorism and get him sent to Gitmo for placing the twins in danger. Knowing Jenny's diplomacy skills, there was a strong chance they would find a way to do it.

Not that Ziva would stop them or even cared. Tucker deserved everything they could throw at him. She had heard tales of child killers being attacked by other prisoners in American prisons and hoped Tucker would be attacked too. Killing children was a cowardly thing to do. They could not stand up for themselves, not protect themselves in any way. They relied on adults to take care of them. Tucker was in a position where he should have been looking after children, which only made his crime worse.

"Why did you do it?" she demanded, slamming her hand down on the table.

Tucker jumped. "I didn't do anything wrong," he whined.

"You killed innocent babies," she yelled at him. "You are nothing more than a coward."

"Kaye was supposed to save them!" he shouted back, losing control. "He's a good doctor. Saving the other children made him invaluable to the hospital. They promoted him. He saved more children than those who died because he is such a great doctor!"

She stared at him. This man was truly insane. "But you are responsible for the deaths of at least twelve children," she pointed out.

He smiled. "A small price to pay for the greater good. People see Kaye for what he is now. I'm not the only one who sees his skills."

Ziva stood up abruptly and left. She did not want to be in a room with this monster for a second longer.

Ducky sighed as he considered the ways things had gone. He had tried to deal with some paperwork in Autopsy, but had been unable to work due to a strange feeling of someone being nearby. After a quick check of the morgue drawers, he had found Lily curled up inside one of them. She claimed to be having a nap, but the fact someone had locked her in from the outside discounted that slightly.

He had then left in order to find Jethro and point out that he couldn't change Lily by locking her inside a morgue drawer. Jethro had been at his desk, playing with his children, and had refused to accept the possibility that he might have been in some way responsible for anything that happened to Lily. He had also bought up the idea of Lily 'just taking a nap'.

Someone really needed to bash their heads together. Normally that someone was Jenny, but she was too busy fuming at Lily to pay attention to the fight that was brewing between her NCIS agent and a certain CIA agent.

And it really did not help that Lily was refusing to own up to the bomb in Jenny's office. Ducky was starting to come round to her side. She was extremely persistent in repeating her claim, she was not likely to set off two bombs in one day, and she was incredibly unlikely to do anything that might harm her sister. Not to mention that Lily usually owned up immediately when she had done something she considered to be spectacular. It simply did not fit in with her world view.

This, of course, left the worrying thought that someone else had blown up Jenny's office, but he did not have too much time to ponder it. Lily had shown up in the squad room, Abby by her side, and they had proceeded to borrow the twins. Whereas Abby was being careful with them and making sure she did not leave Jethro's sight, Lily was attempting to smuggle them out of the squad room, much to Jethro's dismay. The redhead never seemed to learn from her previous actions.

"Why would anyone kill babies?" McGee wondered aloud.

Ducky guessed the question might be directed at him. "That is a very complex question," he began. "Most killers – people who have killed other adults – tend to act hastily. They either carry an attack too far, do something on the spur of a moment, or commit something that is almost accidental in nature. A small minority of killers plan their attack or attacks out carefully. These are the ones which we have to work hard to catch. Sometimes they manage to slide their killings under the radar. In cases of killing children, it seems they believe they are powerful."

"So basically they're insane," Lily piped up, not looking up from her attempt to drop Camilla down the back of the filing cabinet.

"I am sure that will be his defense," Ducky admitted.

"How's the attempt at sending him to Gitmo going, boss?" Tony asked.

Jethro merely growled, before intercepting Camilla and glaring at Lily. Nothing new there then.

Abby was happy to be given Camilla back. Lily's antics with the twins were likely to end with someone being hurt, even though that person was most likely to be Lily herself when Mommy and Daddy ripped her to pieces.

She was only having fun with them! The twins were content and babbling away, as usual, none the worse for wear. Lily wouldn't actually hurt them in any way. She loved them because they were her nieces. Gibbs was wrong when he tried to keep Lily in line.

She was determined to teach the twins how to speak. After the horror of finding out that a serial killer had been operating at Bethesda for so long, she wanted to relax. And the babies had been put in danger so she had to make sure that they were not suffering any lasting damage. Maybe she should persuade Ducky to check them over again. He might have missed something in the last five checks she had forced him to carry out.

You could never be too careful with babies. Everything you did around them would have an effect on them as they grew up, or so she believed. And these children already had one crazy family. Their father was practically psychic and would be over-protective, their mother was a diplomat and would smother them in affection, and they had an aunt who would rather die than let anything happen to them.

Not to mention their extended family. Tony was already trying to get them to watch movies, although it was clear they were not interested in explosions on a screen, which might be a good thing with Lily as their aunt. Ziva was trying to teach them little methods of self-defense, even though they did not understand what it was and could not carry out any of the moves. Ducky told them long stories about his childhood in Scotland. McGee read parts of his Gemcity novels to them, using them as a little audience and asking their opinions at various stages. She herself tried to explain long complex scientific terms to them. Even Palmer had been caught trying to explain how the digestive system worked, just before an important exam.

She lowered her head so that she was face to face with Rose, and tried again. "Daddy," she enunciated clearly. "Daddy." She pointed at Gibbs.

"Don't bother," Gibbs warned, taking a sip from his coffee. "They haven't started making sense yet."

"But Gibbs!" she objected. "They're six months old! We have to get sense out of them, or how are we supposed to know what they want?"

Gibbs chuckled. "Once they start speaking, you'll only want them to stop," he pointed out. "Young children do not understand the term 'no'."

"Jasper understood it at nine months old," Lily offered from across the squad room.

"You weren't exactly around," Gibbs shot back.

"He's an angel," she smiled.

"Where is your son anyway?" Gibbs checked, suddenly suspicious.

"Spending some time with Jenny," she remarked. "I'm not going to stop him. We were supposed to spend today at the zoo."

"Daddy," Abby tried again, knowing full well that Gibbs and Lily would start screaming at each other in a minute. "Daddy."

"Dadadadadadadadadada," Rose pronounced, a slight grin on her face.

From her spot on Gibbs' desk, Camilla joined in without any prompting. "Dadadadadadada."

Abby screamed with delight.
