Ari as promised met his sister on the plane she was sitting on one of the seats with a plastic table in front of it. He took a seat across from her "Where'd you go?" she asked him innocently. "I went to follow up on lead." He lied smoothly. "You were following a lead in Georgetown?" Ziva asked not believing him. "Yes" he lied again. "Quit lying Ari. It's beneath you." Ziva said in an annoyed tone. "You went to that woman's apartment." She said getting angrier. Ari didn't try to lie this time "How did you know?" he said feeling defeated. "I tracked your cell phone." She said pointing to the laptop beside her.

"What I don't understand is what you were doing there." Ziva admitted. Then she looked at him more specifically she looked at his mouth and squinted she could still see tiny specks of blood on his teeth. She put a hand on her forehead and looked down "Oh my god Ari what did you do?" she said in their native language. She looked up and answered her own question "You bit her." She said barely above a whisper because she didn't want anybody else on the plane to hear. "You bite people all of the time." He said suddenly feeling defensive. "Feeders. Ari I bite feeders. I don't go around biting random human girls." Ziva said feeling frustrated. "Ari this is serious. What if she tells someone?" "She won't." He said definitely. "You used compulsion on her." Ziva stated past the point of feeling shocked. Ari sat there thinking about why he'd done it his reasons didn't seem like actual reasons anymore. "You're in love with her." Ziva suddenly said. That's an explanation he hadn't thought of. "That's ridiculous Ziva. How can I be in love with her?" he said incredulously. "I know how your mind works ever since you were a little kid you've wanted what you couldn't have. So it follows a pattern of thinking that the one girl that you fall for happens to be human." Ziva said feeling a mix of pride for figuring it out so quickly and anger at her brother's stupidity. He sat in silence thinking about his sister's deductions. Could he really be in love with Caitlin? The siblings sat in silence the rest of the flight of Russia.

Kate woke up the next day completely and utterly perplexed by her dream and the fact that it didn't seem like a dream it felt real. She shook those thoughts out of her head like a terrorist would really break into her apartment in the middle of the night to bite her. She got out of bed and went into her bathroom where she looked in a mirror and saw the bruises on her neck. "Oh great a hickey that's all Tony needs to see." She thought. She decided to wear a turtleneck sweater and she also decided she was never going to see Tony's frat brother again.

She got off the elevator and walked into the bullpen. "Hey Katie how's it going?" Tony said flirtatiously when he saw her. She sat at her desk "Rockin' the turtleneck today, are we?" he grinned at her. "Obviously." She said while pretending to do some paperwork. "it's almost June wearing a turtleneck in this weather can only mean one thing. I know what it is do you know what it is, probie?" he said turning to the probationary field agent on the team Tim McGee. "That she's cold?" McGee said dumbfounded. "No probie it means someone's got a hickey." Tony said walking back towards Kate's desk. "Come on Kate let me see." "DiNozzo quit it I'm not in the mood today." Kate snapped.

Just then their boss Leroy Jethro Gibbs stepped off the elevator "Grab your gear. We got a dead marine in Maryland." He said without paying any attention to Kate and Tony. They rode in silence to the crime scene any worked quickly when they arrived.

Later in the day Kate brought samples down to NCIS' forensic expert Abby Scuito. While Abby was looking over the samples Kate was scratching at her turtleneck. "I've got an extra shirt you can change into, if you want." Abby said while she was looking through her microscope. Kate didn't think twice and she went to change in Abby's office. Kate went back into the lab in a shirt that was a little too big for her. The first thing Abby noticed were the bruises on Kate's neck "wow that's quite a hickey you got there, Kate." She said almost cheerfully. "I mean seriously, what was the guy a vampire, or something?" Abby asked jokingly. Kate rolled her eyes leave it to the gothic Abby to jump on the vampire train.

Ziva and Ari's plane landed on a remote airstrip in Russia. They got off the plane and were greeted by an alchemist who works with them. "We tracked your guy down. We know he's somewhere in Kiev but we don't have an exact location." "Do you ever Sydney?" Ari asked sarcastically. Sydney ignored him "Rose wants to talk to you, Ziva." Sydney said while handing her a cell phone. Ziva took the phone and walked off leaving Sydney and Ari along together. They stood in silence until she returned.

"Rose gave me the names of some strigoi hangouts in the city that we should check." Ziva said to Ari. "Call me when there's a body." Sydney interjected before leaving. "Is it just me or has she gotten more bitter in the cold?" Ari whispered to Ziva. "Come on we can check a couple of these places before sunrise." Ziva said leading Ari to a car.

Ari got into the driver's side of a black Lincoln Navigator. Ziva glided into the passenger seat with grace stemming from her years of ballet. She opened up her laptop bag and took out a blood bag. She twisted the end of a small tube off to open it and began to drink. Ari glanced over at her "What?" she said when she noticed him. "Nothing" he said then turned his attention back to the road. "What's the matter?" She asked slightly annoyed by his evasiveness. He sighed "you said that I was in love with Caitlin." "I said that because it's true." Ziva stated simply. "Why do you think that?" Ari asked curiously. "Well, for starters you actually called her by her name." Ziva said before she went back to her blood bag.

They went to two places strigoi frequented before the sun came up after that they went to the safe house that was set up for them. It was 8:00 in the morning or 8:00 at night if you live on a nocturnal schedule when Ziva got up to go to the bathroom and she saw Ari just sitting at the table. She walked over to the table and sat down across from him.

She knew what this was about she didn't have to ask him "you know you can't be with her Ari she's human." She said seriously. "Why not humans and moroi used to be together all time?" he argued. "Ari that was centuries ago things have changed since then." Ziva said still trying to get through to him. "Well maybe they can change back." He said even though he knew his sister was right. "Ari you know that we have to keep what we are secret and even if you could be together could you really live with the fact that she be in constant danger?" She got through to him when she said that he could live with a lot of things but putting Caitlin in danger wasn't one of them.

"You're right." He conceded and got up he walked into his bedroom. Ziva sat there and groaned in frustration. Then she remembered she had something to do she got up and dug through her bag. She finally found what she was looking for a she picked up the green pill bottle and opened it. She shook one of the little white pills into her hand and slapped it into her mouth. She then swallowed it and put the bottle back into her bag. Then she went to the bathroom and went to bed.

Well she tried to go back to bed anyway but she couldn't fall back to sleep so she decided to call her friend Rose Hathaway. Rose Hathaway is a dhampir, a half human half vampire mix. Even though humans and moroi haven't been together for centuries and ironically dhampirs can't have kids with each other. But when you mix a Moroi and a dhampir together you get perfect dhampir children. Rose is also a guardian for her best friend Valissa or Lissa. "What is it Ziva?" Rose asked sleepily. "Ari's in love." "What!" Rose exclaimed. "How did Hugh find a girl?" Rose asked confusedly. Ziva smiled when she heard Rose say 'Hugh' that was their nickname for Ari in high school because he had so many girlfriends he acted like a Hugh Hefner with fangs.

"Well actually he held her captive." Ziva said then realized she probably needed to explain more. So she told her as much as she could without breaking any rules. "Wow" is all Rose could say "I know so what do I do about it?" Ziva asked. "They can't be together she's human you know that and he knows that." Rose said which Ziva didn't find very helpful because that was the same thing she said to Ari. "Rose I'm going to try and get some sleep. I'll call you later OK." And Ziva hung up the phone.

They were in Russia a full two weeks before their father told them to come home. Their people surmised that James must've left Kiev and that he could be anywhere in Russia or Europe. They were on their way to the airstrip when Ziva got an idea that she knew she was going to regret. But she was like Ari and lacked impulse control so she was going to do it anyway.

They were sitting on the plane and Ari was looking down at his phone going through old e-mails. When the pilot announced they were descending on to an airstrip. "Why are we stopping we can't be in Tel Aviv yet?" Ari asked Ziva with a confused look. "You're actually right for once. We're not in Tel Aviv." Ziva said with a knowing smile. "Then where are we?" Ari asked still really confused. Ziva rolled her eyes "We're in DC." She said it like it was the most natural thing to say. "Why?" "Well this is where your little human lives, isn't it?" Ziva said annoyed slightly that he didn't figure it out sooner. "I thought you were against her and I being together." "I am but I'm more against you being miserable for the rest of your life." Ziva said with a chuckle but Ari could tell she meant it.

"Now go before I change my mind." Ziva said urging him out the door. "Have I told you you're the best sister ever?" Ari said just before jet door opened. "You could stand to mention it more." Ziva said to him "Oh and Ari Isaac will be back to get you in two days." Ziva said referring to the pilot. Ari nodded then jotted down the steps. Then the door closed and Ziva prayed that she was doing a good thing.

Ari then headed off to Catlin's apartment feeling something he almost never felt nervous. When he got there she wasn't home so he just went in and sat down at her kitchen island bar stool. After about 15 minutes she entered her door without noticing him but then she did and she grabbed her gun and pointed it him. "Caitlin please put the gun down I'm just here to talk to you." He said sincerely. "Why should I trust you?" she asked him tensely. "Because if I was going to hurt you I already would have." He reasoned. She considered this and determined that it was true. She set her gun down on an end table. He exhaled "think you." "You said you wanted to talk, so talk." Caitlin said impatiently.


Authors note: I'm having trouble coming up with the name for the agency Ari and Ziva work at. If you have any suggestions let me know.
