Last time on Street fight:

"This is my case and if you come barging in here and stop my investigation I want to know why." Gibbs snapped.

"Are you comfortable?" DiNozzo asked just for curiosity's sake.

"No!" Gaia answered.

"Sorry for asking. Okay, let's begin. State whether the following is true or false:

You are Gaia Moon?"

"I have seriously never seen an LTD this straight." Abby added.

"You are staying here with Abby" Gibbs ordered Gaia.

Chapter 4.

After about thirty minutes, Abby jumped on the phone to get Gibbs.

"What is it Abby? We're busy." He stated when he answered the phone.

"We have a bit of a problem… Gaia disappeared. I'm sorry." Abby said panicky

"Oh no, what happened?"

"She jumped around the lab like a kangaroo on steroids after the coffee and then she said she had to go for a run and she just took off."

"I think I know where she is… I'll go after her. Don't worry Abby. Just finish those DNA results." After hanging up Gibbs thought of the quickest way to get to Gaia.

"I'm going to get Gaia – she ran off." He told the others.

"Boss! I think that will have to wait…" Kate said after she opened the large waste bin and found a corpse.

"Oh no Gaia. What did you do?" Gibbs asked silently.

The body was taken to the lab and the rest of the alleyway was investigated. Nothing else was found except a gun and a bloody bandage.

"A simple shot in the head, Jethro." Ducky informed him. "The shot in the shoulder was perhaps a few days prior to the one in the head. And the bullet from the shoulder had been poorly taken out – if this guy lived longer it would have infected sooner or later. The shot in the head was from the back, so he never saw his killer. Oh and he broke three ribs in the last few months – same time perhaps – it did heal but poorly."

As you can interoperate, Gibbs is in Ducky's lab and he is talking about the corpse they found in the alleyway. The phone rang and Gibbs answered.

"Gibbs! I have a gift for you!" Abby said.

"Is it the DNA results?"

"No"

"The fingerprints? The fibres? The gun? What?"

"Look to the door." Gibbs turned and saw Gaia through the glass. His heart slowed its rapid pace and he could relax about a missing agent. "She came back on her own."

"Thanks Abby." Gibbs said and hung up. He walked to the door and opened it.

"Don't you ever do that again Gaia!" he scolded.

"Never ever give me coffee, Jethro!" she snapped back.

"You shouldn't be here, let's go. I'll get you something else to drink." Gibbs tried to pull her towards the elevator but she stood her ground.

"Is that? … Rocco!" she asked when she recognised the face.

"You know him?" Gibbs asked. "Did you kill him?"

"I wanted to but I didn't – I swear it!" she walked closer and inspected him from a safe distance.

"Hello Gaia!" Ducky greeted her. "We aren't strangers, are we?"

"Sorry Ducky – hi." She looked over Rocco.

"Did you know him?" Gibbs asked again.

"I did. He was a Slasher-gangster. He killed one of my chess friends – and almost me and Sam." She said.

"You wanted to kill him?"

"He slashed two of my friends – killed the one and the other just got away with a few scratch marks. Sam was just in the wrong place at the wrong time. He was thrown around and beaten up and then I got into the fight and I think I broke something of Rocco. Ribs maybe – and his jaw. Then I got Sam away – they were arrested soon enough. But he was released a few weeks ago."

"Do you know who would want to shoot him?"

"Who wouldn't? Not me though, I don't use a gun, I did my damage to him. Nothing more."

"So you have no idea?"

"Not certainly. Maybe the gang leader just wanted him dead because he split on them at the police."

"We'll check it out. Come now." Gibbs led her away.

"Did you find a place Kate?" Gibbs asked. She had been looking for a place where they could station Gaia for the night.

"Yes. It's called… the silver mansion – for some reason. I will stay there with her." Kate answered.

"Okay. Did Abby get the DNA results yet?"

"No, she's working on the gun quickly. She said she's waiting for the computer to trace a match with the blood so she went on with other work." Kate said.

"DiNozzo! Go tell Abby to hurry up, and tell her I want the prints off the gun. Pronto!"

After DiNozzo left Gibbs turned to get the rest of the information from Kate.

"Jethro…" Gaia tried before she slid along the table and collapsed to the floor.

"Gaia!" he ran to her picked her up. Kate pushed a chair closer and Gibbs placed Gaia on it. "Gaia."

She came to and tried to stand up but failed and she sat back down.

"I'm fine, really. It's just a reaction to the coffee," she stated and Kate went back to her work.

When it was seven o'clock Kate packed up her things and took Gaia to the silver mansion.

Gaia and Kate shared a room on the third floor and Kate was highly irritated by the wooden floors. Gaia went straight to bed and later when Kate thought it was safe, she too went to sleep.

Early the next morning they got up and drove back to the office.

"Good morning, Kate – Gaia" McGee greeted cheerfully.

"Morning – is Gibbs in yet?" Kate enquired.

"Yes, he is on his way to Abby. He said he wants to see you when you come in Gaia"

"Okay" Gaia answered then sped off to Abby's lab.

"You want to know the best part?" Abby said to Gibbs when Gaia entered.

"I'm all ears." Gibbs said irritated.

"It's only sold in six shops in the city. So I traced it to 'Security and all' in Bleaker street." She was talking about the bullets that were inside the gun.

"I'll get DiNozzo to go. Anything else?" Gibbs asked.

"Yeah. I … I got a match for the blood on the pavement…"

"And!"

"It matches Gaia … and … you"

A/N: something for the long wait. And I'm not sure that this is possible. I' a writer not an expert. So, no one knows that Gaia is Gibbs daughter – well now Abby will know.
