NCIS

It was a quiet morning. The sky was slightly cloudy, but there was no chance of rain. It was a cool November morning, around 0630 on a Saturday morning. Gibbs woke up from the couch in the living room of his house. He got up and made some coffee, or gut rot as his agents had always said. One, though, had gotten use to his coffee. Tony. Gibbs smiled at the thought of his SFA. Tony had been his one close friend that he had, from the first moment he met him in Baltimore, and then as they worked together at NCIS for 4 years together. He grew fond of the younger man. He filled his cup of coffee and grabbed the paper of the table in the kitchen and read quietly. He gulped down a few ounces of his gut rot and sighed, setting the paper down moments after. There must be something to do... Gibbs thought. He was brought out of his thoughts when the front door opened. Gibbs grabbed a knife from the drawer beside him and was ready to fight if need be.

"Morning boss!" Tony shouted from the door. Gibbs sighed and put the knife back and got up and went to the living room. He watched Tony stand by the door in a pair of old Ohio state sweatpants and a white, long-sleeved shirt.

"Dinozzo what the hell are you doing here this early?" He grumbled. Tony chuckled and patted Gibbs' back. Gibbs squinted at him and Tony cleared his throat.

"Well, thought we could go for a run?" He asked. Gibbs sighed and walked downstairs to the basement with his coffee in hand. He heard Tony walk down behind him, letting each step fall heavily. Gibbs set his coffee down on the workbench and rubbed his temples, his head starting to hurt. "If not, Gibbs, I can go..." Tony said and started to walk upstairs. Gibbs grabbed his hand and sighed.

"How about later?" He asked and Tony nodded. Tony finished walking up the steps and then felt his hand start to itch. He looked down at his hand, the one Gibbs grabbed and made a face. His hand was colored black, but it was very little, and like a powder. He shook his hand and took some of it off, but some still stayed. Tony walked to the door and pulled out his phone, getting into his car.

NCIS

Tony walked into Abby's lab around 0730, seeing a very tired looking Abby. He chuckled and hugged her with one arm, the one without the weird powder. Abby looked at him questionably and he showed her his hand and she gasped.

"Tony that is so cool, what is it?!" Abby shouted. Tony shrugged his shoulders.

"I went to Gibbs' house this morning to ask him to go for a run like we sometimes do together, and when I went to go leave, I noticed my hand start to itch and found this black powder. It was the same hand Gibbs shook. I don't know what it is, but I thought maybe Major Mass Spec might be in for a job?" He looked to Abby, hopeful that it was just blackened saw dust. Abby nodded and started to take some samples of the powder.

"Go wash that hand before it makes the itching worse Tony. I'll call you when I have results." Abby smiled. She hugged him tightly and he kissed her forehead, careful not to touch her with the powdered hand. He walked out of the lab and to the bathroom to wash off the weird powder. As he was washing it off, the powder slowly came off, but dyed his hand a grayish-black color. He sighed and dried off his hand. Tony's phone started to ring and he pulled it out and answered it, not recognizing the number.

"Anthony Dinozzo."

"Dinozzo it's Gibbs. We need to talk." He said hurriedly. He frowned.

"What's up?" He asked, slightly concerned about his boss' tone. He walked out of the bathroom and down the hall, about to take the elevator when Gibbs popped out of the elevator. They both hung up their phones. "So, boss. Sup?" He smiled his million watt smile. Gibbs quickly grabbed Tony's hand with a covered one. Tony looked down at the gloved hand holding his. "Cold?" He chuckled.

"Did you get a black powder on you earlier? When I grabbed you?" He whispered. Tony nodded and frowned. "You didn't bring it to Abby did you?" He whispered, concern laced in his face.

"I did...why?" Tony asked. Gibbs eyes went wide with shock and ran to Abby's lab, Tony running just behind, and just in the nic of time. He grabbed the samples before she put them in Major Mass Spec.

"Gibbs! What the heck! Tony asked me-"

"Yeah I know. But don't." He said firmly. She looked at Gibbs and he shook his head.

"Gibbs what the hell is going on!" Tony burst. Gibbs ran a hand through his hair and sighed.

"Can't talk about it." Gibbs said gruffly and he left. Tony followed the man, leaving Abby pouting and standing in her lab alone.

"Gibbs please, what's going on." He said to the older man. Tony gently placed a hand on the man's shoulder and looked into his eyes. Gibbs looked away and went to the elevator, walking in immediately. Tony followed and got in with Gibbs. Once it got to an in between state, he stopped the elevator and stood in front of the panel. "Tell me." He soothed. Gibbs eyes were closed now, his arms crossed and face facing the floor.

"I can't Tony." He said quietly. "Personal." He said. He shuffled his feet and groaned, holding his neck. Tony frowned.

"You can trust me Gibbs, I promise, your secret's safe with me." Tony said and held his hand out. Gibbs hands gripped the side of the elevator wall as he almost panted.

"Dammit Tony!" He looked up and stared at Tony and he gasped. "What!" He shouted. Tony shakily pointed to his eyes.

"Your eyes... They're not the same. Your pupil is split and..." He stopped. Gibbs started to freak out.

"Press the damn button to get me out of here Dinozzo." Gibbs seethed. Tony quickly pressed the button and Gibbs bit his lip. "You need to go to my place. NOW." He ordered. Tony nodded and both men left the garage, Tony following Gibbs back to his house. Once they pulled in, Gibbs ran to Tony's car and opened the door harshly, grabbing Tony and pulled him in the house. Gibbs pushed the frightened agent on the couch and paced in front of him, deciding how to do this.

"Gibbs?" Tony squeaked in a tiny little voice. Gibbs glared at him and Tony shrunk into the couch. "I-.." Gibbs put a hand up and growled lowly.

"Dinozzo, zip it." He spat.

"I know what you are!" He shouted and covered his mouth with his hands. Gibbs glared at him and stalked towards the couch.

"What do you mean you know what I am?" He said lowly. Tony swallowed hard and closed his eyes, only to open and reveal the same slitted pupils like Gibbs. He blinked and his eyes were normal again and Gibbs stared at him in shock. "You're an Anua." He whispered and nodded. "But how?" He sat down next to Tony, feeling much more relaxed than before. Tony sighed.

"Before my mother died, she told me that we were part of this tribe. She said when I hit puberty, my change would happen, but that I'd be able to control it. When I hit puberty I noticed the changes. My pupils slitted, my skin turned a little more red, but nobody noticed it. My dad explained to me, that whenever I felt an emotion strongly, my hands would leave this powder, and it would be red. I knew I'd have to be careful. My dad told me that when I was older I would start to become more powerful, stronger. I have always made sure I was careful." Tony sighed.

"Have you been in your full form?" Gibbs whispered. Tony nodded.

"It was when Wendy and I broke off our engagement. I was so upset that day. My skin was moist and I grew this long, wispy, black tail that was like six feet long. The powder was flying off my hands like it was snowing. My skin became a dark red and I saw small black dots form in a pattern along my new slimy skin. I remember, looking in the mirror seeing this thing, and I didn't know it was me until after staring for a minute. My hair turned black and my fingers and toes were webbed like a frog's. My dad told me that this form comes out only a few times until you turn 55. It's then that the form becomes permanent. I still have a few years but you... You turn 55 soon don't you?" Tony looked up to the older man and he nodded.

"My change becomes permanent tomorrow." He whispered, looking down into his lap.

"Shit..." Tony whispered.
