It had been a year since Callen had find out that his father was Nikita Alexandr Reznikov. Since then he had tried to use everything he had at his disposal to find his father, with no luck so far. He didn't know if his father was still alive but he had to find out. Maybe he would find something more about his family, maybe even his own first name. Callen had asked Arkady about Nikita but he told him he didn't know anything.

Since he had the tape of his family he had watched it like a million times, trying to see if anything looked familiar to him. He looked so happy in the film. He couldn't remember anything about that time is his life, but at least he had a real family for a short while. He would have loved to see his mother on the film but she was probably the one filming.

The film kept playing in his mind. His father carrying him and his sister kissing his hands as she sat on the swing. He tried to remember his sister but he couldn't. The only memory he had of his sister was the one where she was pushing his cart. There were so many blank pages in his past. He had no idea how he had come to America from Romania, he didn't know his own first name, mostly every part about his childhood before he got to America was a blank.

Callen was at work early this morning, like he was every morning since he had found out about his father, trying to find clues that could lead him to his father. Hetty had told him he couldn't use the services of Eric and Nell and he couldn't do it when he was working. Hetty hated doing that, she knew how much her lead agent wanted to find his father, but she couldn't have him use Eric and Nell for this while they were working, and it weren't her orders, director Vance had told her this.

Within the next hour the other agents walked in as well. About 5 minutes after they were all there Eric whistled them up. Callen was surprised to see Hetty there for them.

"What do we have Eric?" Callen asked as they walked into OPS.

"The DEA office in Moscow sent this over," Eric answered as he put the contents on the big screen. "They were tracking a suspect and found this in his house."

Callen couldn't believe his eyes. Pictures of him appeared on the screen, the same pictures he had found at Reinhardt's place.

"Where did they get these?" Sam asked, his partner was too busy looking at the screen.

"They were in the home of an Evgeny Sivkov," Eric informed them.

"Does the name sound familiar Mr. Callen?" Hetty asked.

"No, I've never heard the name before. Why would he have pictures of me?"

"At this point we don't know," Nell answered. "The DEA office was tracking him cus they think he's link to one of the biggest drug cartels in Moscow."

"Mr. Callen, Mr. Hanna, pack your bags, you're going to Moscow," Hetty told them.

Callen and Sam walked out of the OPS.

"Mr. Callen," Hetty spoke and Callen turned around. "If this has anything to do with your father I would like to know."

Callen nodded and left OPS.

About an hour later Callen and Sam sat in the airplane on their way to Moscow. Sam looked over at his partner who was looking out the window.

"You're gonna be okay G?" Sam asked his partner.

"I'll be fine."

"We don't know what we can expect there. I hope you won't get clouded by the case and have me coming to save your ass."

"I'll be fine Sam."

Sam knew he wasn't going to get much more out of his partner so he decided to let it rest.

About 14 hours later they were at Moscow airport. Hetty had made arrangements and someone from the DEA office was picking them up.

"Agent Callen, Agent Hanna, thank you for coming, my name is Agent Evans," the man spoke as he shook Callen and Sam's hand.

He drove them to the office.

"What do you know about the suspect?" Callen asked.

"We've been tracking him for several months now. We believe he's a member of a drug cartel here in Moscow."

"Do you have any idea why he would have pictures of me?"

"No, not a clue. We ran facial reg on the pictures and when we got a hit on you and saw it was classified we called NCIS, Director Vance told me you were an Agent with the agency he asked us to send the case over to OSP. We were hoping you could help us with this case. Director Vance insisted we had your help on this case and make sure your identity was still safe. Have you ever heard Sivkov?"

"I've spend a lot of time in Russia when I was with the DEA and CIA but I've never heard of this man."

Sam knew his partner wouldn't tell them about the possible link to his family so Sam decided to speak up. If it was vital to the case he would have let it go but he had to tell them.

"About a year back we found the same pictures in a house in one of our cases," Sam spoke as looked over at Callen. He could see that his partner didn't like him telling this. "We thought it was G's father but it turned out he was keeping an eye on him for his father. His name was Michael Reinhardt, he was killed by the Comescu's."

"Do you think the two are connected?"

"It could be."

"Do you know the name of your father?" Agent Evans asked Callen.

Callen was hesitant to speak up so Sam did. "Nikita Alexandr Reznikov."

The two DEA agents looked at each other. Callen caught it.

"Do you know him?" He asked hopeful.

"We have heard his name."

"You're investigating him? Has he got something to do with this investigation?" Callen asked.

The agents looked at each other, not sure if they should tell this information.

"What is it?" Sam pressed.

"He's not just involved with this investigation, he is this investigation."

"Meaning?" Callen asked confused.

They agents feared what Callen's reaction would be if he know. "He is our asset inside the cartel."

"He's working for you?" Callen asked confused.

"Sort of."

"Don't keep doing this. Tell me what is going on!" Callen snapped.

Agent Evans sighed. Callen deserved to know what was going on, especially if Nikita was in fact his father.

"The DEA found Nikita about 30 years ago in a labor camp in Siberia. We were called over there to investigate a possible drug ring with the labor camp. Nikita was part of that drug ring, he was just a low member in the ring so we made a deal with him. He would go free if he helped us catch this ring. With his help we caught the members of the drug ring and put them away. We managed to get Nikita out of the labor camp. We put him in a safe house and gave him a new identity. We made a deal with him, he could go free but if we ever needed him for a case he would help us. After what happened to his wife and kids he was eager to help the US government."

Callen thought back to his time in Romania, him playing on the beach making sand castle and his mother sitting in the chair. She was laughing. Then it all went south. She was killed. Callen didn't remember much afterwards.

"He helped us take down several drug cartels over the years. He's been in place with this drug cartel for a little more than a month."

Callen couldn't believe it. His father was still alive!
