Two hours later, everyone was at Tony's apartment waiting for Michele to show up. Tony was sitting on the couch with Gibbs next to him holding him. Jethro was afraid to move, Tony seemed more fragile than ever before. When the knock finally came at the door, everyone jumped. Tim stood first and walked to the door letting Michele and a woman they had never seen before enter.

"Michele you didn't say anything about another person." Gibbs growled.

"Agent Gibbs, this is Yasmine Kohl, she is the one who put two and two and got NCIS."

"I work for Fornell, Agent Gibbs." the woman said softly.

"Does Fornell know about…" Gibbs waved his hand between the trio of hemolagnias.

Yasmine tipped her head to the side, "He knows I'm different and have a few medical issues that have to be treated by a specialist." When she said treated Yasmine had used hand quotes. "No specifics though."

"How do you get through the day at the FBI drinking?" Tim asked.

"My partner is a clerical person in my department, we just take our breaks at the same time."

"Are they one of the uhh…" Tony couldn't think of the word Michele had used for his partner.

"Polycythemia." Yasmine offered up, "yes, she is."

"So I'm guessing you knew Tony from when he was framed for murder?" Tim asked again.

"Yes there was nothing in his DNA profile then that showed his hemolagnia but when Michele brought me one of the samples I knew those markers looked familiar. I'm sorry but I ran it thought the database so I could figure out why I knew it." Yasmine said chagrinned.

Gibbs glared but didn't say anything Ziva however did, "Ms. Kohl what if that had been noticed by someone, we have worked very hard to keep this from being known."

"I know, I erased the search as soon as the answer came up and before you ask I have duel degrees in computer forensics and biochemistry. I know how to get rid of a computer trail."

"Damn, McGee she's you and Abby combined. She can kill without leaving trace and if she does, she can wipe it out of the logs." Tony said quietly.

"Yes, Agent Dinozzo I can."

"So now that we know the how you id'ed us, how about we get to some answers." Gibbs said.

Michele started, "I have asked the oldest of our kind, none know of any that could bring their teeth on without using sex. One elder did know of someone from the beginning of his time that drank from both sexes."

"Wait, Michele what is the average life span of a hemolagnia?" Ducky quickly asked.

"Roughly a 150 years. The person I know is 142. The person he knew was 98 at the time."

"So they are most likely gone?" Abby asked.

"Yes I'm sorry, they pasted about 30 years ago. They are the only one we know if in our history. Besides Tony and as for the newest change, Tony is the only one. We really are still trying to figure out how the genetic change is propagated. Because other than Sylvia, there are no children born to any hemolagnia after the change happens. A few from before and that we have found none of the children before have the trait."

Tony only groaned and stood up and began to pace at that news. "Why did you run the pregnancy test?" Jimmy asked

"Hm?" Michele had been watching Tony and hadn't been paying attention. "Why did you run the test for pregnancy, when you knew Tony was a man?"

"Oh there is a newer tech in the lab who didn't know Tony was a man, he ran everything because he was unsure what to look for, he didn't have the file that went with the samples. It was only after he told me that the only thing he had found different from any other sample he had run was that the subject appeared to be pregnant. When I told him that the subject was in fact a man he was sure he was going to be fired for somehow contaminating the sample. Our procedure it to test 3 vials and keep two secured just encase something like this happens, I had the other 2 techs test for pregnancy. When they came back as well, I broke the protocol and tested one of the others leaving the last one alone. Did you by chance take your own sample encase somehow our vials were contaminated before Tony's sample was even taken?"

"No but we could," Ducky offered, "I have a kit in the car."

Tony cursed softly, "Get it, I want this fucking done with."

Michele took a step toward Tony with his hand extended as if to touch the younger mans shoulder but he saw Gibbs shake his head and dropped his hand to his side. "Tony we understand this is hard on you, first the change and now the possibility that…"

"Yeah I know, look I'm sorry I'm bitchy." Tony said trying to sound sincere.

"Tony if it's true and you are, we might be able to find a way for others to have children. There are many who would like to, myself included." Michele explained

Tony stopped, "I guess I have been selfish huh? Only worrying about what this means to me."

"Tony none of us begrudge you a little pitty party, in all of this, the world keeps throwing curve balls at you, can't keep up with let alone slam out of the park." Tim said trying to lighten the mood.

"Thanks McDouble header." Tony smiled for the first time in days and everyone in the room breather easier.

Ducky appeared with his bag and looked at Abby, the two of them steered Tony towards one of the kitchen chairs. "Just do it quick please guys?" Tony whispered and closed his eyes. Ducky was quick and efficient and had the vial in less than a minute.

"I'll take this back the yard and run it. I'll call when I know something." Abby said before she kissed Tony's forehead.

After Abby left Michele cleared his throat, "I know this is none of my business but we are a little curious about who the well who the other father is?" he finished looking at the men in the room.

"I am." Gibbs said.

"I had guess as much." Michele answered back, "When the baby comes would you permit us a sample of your DNA as well as the baby's? Maybe it is a combination between yours and Tony's DNA that created the new changes."

"Michele would you please stop talk about my sex life?"

"I know it is hard Tony, we have had years to adjust to the things this does. You have not and yours is different but several of us would like to be able to have some of what you have. The prospect of children, the control over our teeth, how much and who we drink from, these are all things we well covet."

"Tony I think we forgot to tell Michele about the other thing too." Jimmy said.

"Shit yeah you guys do it. I'm going to go lay down for a while. I have a headache and NO it's not that kind of headache." Tony clarified before anyone could ask.

"What kind of headache?" Michele asked when the door to Tony's room closed.

"When Tony goes to long without drinking he gets a headache at the base of his skull. Then he gets double vision and he seems to, we have no way to describe it but to say he melts into himself." Ziva said trying to describe what she had seen the morning she was late. "He also gets a scent."

"Bad meat and flowers." McGee said. Michele just looked at them jaw dropped and Yasmine had her hand to her mouth covering it.

"He is very different from us but the markers are identical." Yasmine explained.

"Look, tell us what happens to you guys then." Jimmy said.

"If one of us goes without drinking we have excorticating stomach pains, no headaches, no vision changes, no scent that any of us has ever mentioned. Jimmy, you said there was something none of you had mentioned what is it?"

Poor Jimmy went beet red in seconds and stammered over himself, Tim laid a hand on Jimmy's shoulder and Jimmy took a deep breath and answered Michele. "If both people come just before Tony Drinks we can avoid sex without the painful side effects."

"Oral sex I assume." Yasmine said.

"Or mutual masturbation." Jimmy said even more embarrassed than before.

"That would be handy." Yasmine lamented. "The one office in my building that is safe is not very comfortable."

"How did you find this out? I know it's intrusive but anything that may help." Michele asked.

Jimmy still red stammered, "When Tony told all of us, I offered to help but I was...I had never been with a man… so was extremely nervous."

"Like now." Michele said with a smile.

"Worse." Jimmy said honestly, "Tony just kept kissing me and I finally relaxed, I thought he was going to uhum…"

"Yes we get it." Yasmine said blushing on Jimmy's behalf.

"But he…" Jimmy's voice cracked and he shifted in the chair he had taken.

"What Mr. Palmer is trying to say delicately is that Tony used oral sex and masturbation as the sexual act and as they both finished Tony drank from Mr. Palmer's femoral artery." Ducky finished.

Jimmy coughed and squirmed again, "Yes that's what I'm trying to say."

Michele and Yasmine both nodded.

"Michele, may I ask if anyone has quantified the amount of blood that you need?"

"No Dr. Mallard, it varies. I need roughly two and half pints."

Yasmine said, "I need just over pint."

"Markus needs the most that we know of, with 4 pints it is why he has several lovers."

"And you can find no reason for the variations?" Jimmy asked now that the focus was off what he a Tony did he was less flustered.

"No not really nothing that we can pin point." Yasmine explained.

Michele offered, "As far as illnesses as a child or injuries that occurred, there doesn't seem to be any correlation."

"Have you found what might be a trigger for the change?" Ducky asked, "Tony said that you reacted oddly when he said he had only been changed for a short time."

"Yes Dr. Mallard, it is odd. Until Tony the oldest change had happened with Sylvia's mother, Jennifer, she was 23."

"Tony was 37." McGee informed Michele and Yasmine.

"There is nothing traditional about Anthony Dinozzo is there? Yasmine asked.
