New York-Washington D.C

Kate was nervous when she clicked the link that led to her brother's life.

"Okay...wow he's a federal agent...works for NCIS in D.C...and...that's about everything that damn file on the damn computer says….but it's still enough to find him."

So she got up and went to Gates office asking for a couple of days off. The Captain agreed because Kate never...ever took vacation leave. She almost fell off her chair when she heard Kate wanted a whole week though.

Kate got out of her office and told Ryan and Esposito they were in charge for a few days and left the 12th with Castle. They went to the loft first to get a few things and telling Alexis she'd be alone with her gram for a couple of days.

They went to sleep in Kate's apartment, because it was nearer to the airport. There were only a few things left at her place like a bed. Actually it was more of a mattress on the floor, but enough to sleep on.

The next morning the alarm went off at 7am; their flight left at 10am. They got up, dressed and left for the airport. The day before Kate had managed to get two seats next to each other on the plane. The flight wasn't long but about halfway through the flight Kate's hands began to shake and Castle gave them a light squeeze.

"You okay?" he asked when it didn't stop them.

"What if he doesn't like me or what if he doesn't even want to know me? Rick what am I going to do if he doesn't even want to know who I am?" she asked terrified.

"Hey calm down. I'm here and I'm sure he's going to love you Kate. I love you." This calmed her down a little and soon the pilot announced they were 5minutes away from the airport.

After they landed Kate and Rick went straight to a cab and drove to the Navy Yard. It was big. Kate hadn't thought NCIS was that big but it was a nice building.

They got through security, where she had to give them her gun, to the elevator and went to the main floor. There was only one person on a desk so they walked to that desk where a young man sat.

He looked up when he heard footsteps and asked:

"Hey, how can I help you?"

Kate felt her heartbeat quicken and said: "I...I'm looking for Tony DiNozzo!" The young man was about to answer when they heard someone yell at him.

Washington D.C earlier that day

When Tony and Ziva woke up on the oh so comfortable couch of his they got dressed and headed to the Navy Yard so they could continue to look for Tony's sister. Tony also wanted to find McGee because he wasn't as good in hacking and the McHacker wasn't there yesterday which means he couldn't ask him for help.

He had already spent an entire day looking for her and both Ziva and Tony hadn't found anything useful. They were federal agents for god's sake. It should be easy.

When they came out of the elevator he saw McGee at his desk and Gibbs was nowhere to be seen, so he figured the best way to get his attention was to yell all the way across the bullpen.

"Hey Probie, where the hell were you yesterday? I needed your help to hack into a system. I really need to find my si..." Then he really noticed the two people standing in front of McGee's desk 'hmm a hot woman in front of Probilicius' desk...' he thought as they both turned around. McGee just rolled his eyes and turned back to Kate:

"So what can I help you with again? Sorry for my coworker."

Kate smiled and sontinued what she was about to say.

"I'm looking for Tony DiNozzo." McGee stood up and when she said who she was looking for he just muttered something she couldn't understand and just then the coworker exclaimed: "Ahhh that would be me..!"

She looked at him and didn't say a word. She was standing in front of her brother. She didn't know what to say. She didn't pay attention to the woman standing next to him, because she was standing in front of her freakin' BROTHER. The one she didn't even know about 24houres ago.

Tony raised his eyebrows at her. He didn't understand why she was looking for him and right now she was just Standing there and looking at him as if he was some kind of alien.

"Okay you were looking for me so what can I do for you?" he asked when he saw that she wasn't going to talk anytime soon.

Castle looked at her waiting for her to answer which she still didn't so he said:

"Could we talk to you for a minute?" He saw the 'I have better things to do than to talk to you' look on Tony's face but he just answered:

"Yeah sure but could we make this quick?! I've got something really important to do!" Castle nodded and Tony quickly kissed Ziva and made his way to a conference room with Kate and Castle.

"Okay...who are you and what did you wanna talk to me about?"

This time Kate was past the shock of meeting her brother so she was the one to answere:

"I'm...Kate Beckett," she began and Looked at Castle who gave her hand a soft squeeze to make her continue, "so...I know it's gonna sound weird but...,"

Tony was getting worried because that woman's hands were shaking like he had never seen it...wait she said her name was Kate...could it be...? When she continued his thoughts were confirmed,

"I'm your sister" she said.
