A/N: So this totally AU, in the sense of Gibbs' family and ex-wives, but hopefully it will all be explained int he course of the story, with flashbacks and story-telling. Also, I know nothing about drugs or how to take them, or anything like that, so forgive me if this first part, and some future parts, sound completely unreal and idiotic. I'm going to try and not make this OC oriented, and keep it more focused around Tony, Gibbs and their interactions with my OC. Hope you guys like it.

Anthony DiNozzo, or Steven Ritz as he was being called recently, walked through the warehouse with a small package under his arm, ignoring the glares and calculated looks that were being shot his way. They didn't like it when a new guy managed to make his way into the higher ranks before they did. He locked eyes with Tamara Jet as he approached her and Gavin Levine, head of the DC drug ring.

"That our newest merchandise, Ritz?" Gavin took the package from Tony and dropped it on top of wooden crate. Tamara just rolled her eyes and smirked at Tony, who returned the gesture.

"I think I can handle a little pick-up job." Tony had been working undercover for almost two months and had managed to get enough evidence to take the ring down, but the Agencies wanted a sample of the drugs do they could get full convictions. He had struck a friendship, and what could be interpreted as a small romance, with Tamara Jet who was Gavin's right hand girl. She reminded Tony of someone, but he could never place the resemblance.

"Knew you could, just had to test your loyalties." Gavin pulled out a knife and sliced the paper off of the package. Inside was Gavin's 'merchandise', genetically experimented cocaine. The higher-ups wanted Tony to find out what was so special about it before it made it out to the streets.

"As you can see I didn't test the product, or anything else like that." Tony defended.

"Damn, leave him alone, Gav," Tamara sighed and leaned against the crate. "You can be such a bastard sometimes."

"I learned from the best then, Tammy." Gavin spat at her. Tamara's eyes narrowed and she growled at him.

"Don't call me that. Now what the hell is so important with this new shit?" Tony was glad that the fiery woman in front of him had asked the question.

"Something that is going to make us a fortune." Gavin smirked and looked at the young woman. "You wanna shoot it or smoke it?"

"What did I tell you before?" Tamara frowned at her partner. "I just help you, I don't do that shit anymore." Tony was almost proud of her. But it seemed that Gavin had ignored what she said and was pulling out a small glass pipe.

"You'll be perfect to try it for me." He dropped some of the powder into the pipe and pulled out a lighter, handing both to Tamara. "You can tell me if there' a noticeable difference."

"Not until you tell me what's in this." She didn't flinch when Gavin pulled his gun from the back of his jeans and held it up to her temple. She didn't move, blink or back down though.

"Fine," Gavin sighed and rolled his eyes, never moving the gun. Tony tried to hide his hand making his way to his own gun. "I get the complaints from all the pregnant women, so I had this stuff altered so that it wouldn't affect the babies, or anything like that. There's even an added quick for the chicks that wanna get knocked up."

Tony felt that Gavin was hiding more but it seemed that Tamara wasn't going to be getting anything else out of him, and reluctantly smoked the sample she was given. Gavin grinned and put his gun back, turning back to his newest money maker. Now tony just need to contact Gibbs and the Director tonight and he would be on his way out.

"Ritz, take Tammy back to her apartment. I don't want her messing up the operations around here while she's high." Gavin never turned to look at Tony. Tony walked over and slung her arm around his shoulder and helped her stumble out of the building and to his car.

Tony glanced at Tamara and noticed how she rested her head on the glass of the window as he drove. "You know, he's gonna screw you over when this is over."

"Yah, I know," her words slurred slightly, but it was obviously that she wasn't feeling good, she wasn't having that sense of euphoria that other users experienced. "But I got no where else to go, Tony."

Tony's eyes widened and he almost missed a stop sign. "What the hell?"

"Oh please," she snorted, closing her eyes. "If you weren't so damned loveable and handsome I would have told Gavin that your were undercover. I'm not stupid, investigating is in my blood." She nearly spat the last part out. Tony decided to go out on a limb.

"I'm calling my boss, like as soon as I get you back to your apartment. If you can help, give them information, you can get a deal, avoid getting a life sentence." It was silent in the car, even after he parked and stopped the car, and Tony was afraid that Tamara had fallen asleep.

"What else do I have to lose? Everyone there will be arrested, might as well become the FBI's lackey then fight the rest of my life in prison." She sighed and opened her eyes, looking at Tony.

"Actually, I'm NCIS." He got out of the car before she could say anything. He helped her out of the passenger side and they made their way up the stairs. Tamara dropped on the couch, throwing a pillow over her head as Tony locked the door, pulling out his cell phone.

"Yeah, Gibbs," Tony smiled at the familiar greeting.

"Hey, Boss, guess who?"

"Tony, what's going on?" Gibbs was instantly at attention as his Senior Field Agent's voice.

"I think I got what we're all looking for, it's time to move in." He glanced at Tamara. Gibbs seemed to sense that there was some hesitation.

"And what's the exception?"

"One of them wants to help, doesn't wanna go down with the rest of them. She'll help give information." Tony explained, walking towards the kitchen.

"We'll see what we can do." He could hear the team in the background gearing up and moving quickly. "We're getting the FBI, we'll be there soon." The line disconnected and Tony shook his head. He then went about Tamara's kitchen getting her something the drink, this not being the only time he had brought her home after Gavin had forced her to try a new shipment.

Tony sat down and looked at Tamara, thinking that she had finally fallen asleep. "I wasn't kidding when I said you were loveable and handsome. Probably the reason I slept with you last week." Tony blinked when she started talking. "I would go as far to say that I might have started to fall for you."

"Past tense?" Tony raised an eyebrow, not wanting to admit that he was starting to feel the same.

"Well, yah. Who knows where I'll be once your people move in. I'll be giving names and information, and who knows." She turned so she was laying on her back. "Kind of depressing to think about."

"Crack really makes you open up, you know that right?" Tony teased a little.

"Kiss my ass, Tony."

"Did that last week."

Several hours later Tony was roused from his nap by drops of water landing on his face. He blinked and looked up to see Tamara leaning over him, her long brown hair in a ponytail, and the ends dripping. "Have a nice nap?"

Tony sat up and stretched his arms, yawning. "I was until I ended up getting wet." The door suddenly slammed open before Tony could say anything else. He jumped up and his hand went reaching for his gun, subconsciously standing in front of Tamara.

"Either one of you move, and I'll swear I'll kill you," they were faced with an angry Gavin, holding a gun in each hand at them. "I wanna know who called the damned Feds."

"What the hell are you talking? We were here the whole time, him asleep, and I was fucking tripped out Gavin." Tony was silently surprised that she was covering for him.

"I'm not fucking stupid." Gavin growled out. Tamara moved one of her arms and Gavin let out a shot. Tony yelled and fell to the floor, a dark spot quickly growing on the thigh of his jeans. "I said don't move!"

"Some advice you'd better take yourself." Tony looked up when he heard the voice of his boss. Gibbs was looking at Gavin with his own gun trained on his head, Ziva, McGee and Fornell taking positions behind him. "Drop the guns."

"Not until I kill this little bitch." Tony looked at Gavin, expecting to see the barrels of the guns pointed at him, but they were trained on the woman behind him. He glanced up and saw the look of shock on Tamara's face, but she was looking at Gibbs. Now Tony was confused. "She ratted me out!"

"No she didn't!" Tony yelled out before Gavin could get trigger happy again. "My name's Tony DiNozzo, I'm the fed that called it in." He could almost feel Gibbs slapping the back of his head.

"Doesn't matter anymore." Tony opened his mouth but was suddenly met with a barrage of shots being fired. Tony ducked down as far as he could, covering his head, and remained that way several minutes after the shots stopped.

He opened his eyes and saw Gavin lying on the ground, unconscious, but breathing, and Fornell was slapping some cuffs on him. McGee was on the phone calling an ambulance and Ziva was also on her phone. Gibbs was suddenly leaning front of him.

"Is she the one you wanna help?" Tony nodded then turned his head but didn't see Tamara.

"Where is she?" Tony started to worry that Gavin had shot her before he went down.

"She's fine. What's her name?" Gibbs stood up and headed for the chair behind Tony. Upon closer inspection he could see her foot on the ground, she had hidden behind the chair to avoid getting hurt.

"Don't you come any closer to this chair!" Tony blinked when Tamara yelled, stopping Gibbs in his tracks, and pulling the attention of Fornell.

"Gonna be kinda hard to help you if I can get closer."

"I don't care. Anyone else but you can help me." They heard her move a little behind the chair, moving when Gibbs did so he still couldn't see her. Gibbs shot Tony a look.

"This is my Boss, Agent Le-"

"Leroy Jethro Gibbs, I know damn well who he is." Tony blinked.

"Are you Tamara Jet?" Fornell asked, probably having read through the files recently. Tony saw Gibbs shoulders tense and straighten up. He grabbed the arms of the chair and pushed it to the side, grabbing Tamara's arm and lifting her up to face him. Her eyes narrowed at him as Gibb's own widened.

"Tammy?"
