…………In the house……….

"Abby, how did you know the code?" McGee asked her.

"They told me. For them it was really important that I knew the code. I don't know why just they wanted someone close to them to know much about them but I don't know why they suddenly left or where they are." Abby explained to McGee and Gibbs.

"How long have they've been married? I always thought Kate would want a wedding with every friend and every family member." Gibbs asked her.

"They don't know they are married. Everyone thinks they are dating and plan to get married in the end of next year. McGee only thought they were dating not living together and also married." Abby further explained.

"You have a lot to explain. I can't believe you three kept this a secret from me. Did they leave because they were afraid of my reaction to all of this?" Gibbs wondered.

"I know it isn't the reason." Abby quickly answered without even thinking.

"Then what is the reason?" McGee asked while looking around.

"I don't know." Abby said while slowly going away from them. The tension was building now and she knew when it would blow up it would be aimed towards her. She hoped they couldn't tell that she really knew why they left.

"You've never failed me yet and now I can't believe you. Abby, sit down in the sofa and don't move. We're going to search the house." Gibbs told her. She was like a daughter to him and it hurt so much not being able to trust and believe her now. What had they been up to?

………………

McGee and Gibbs searched the house for clues while Abby sat there. She looked at the pictures of the couple. They seemed so happy. Once again she took up her cell phone to see if they had called her but they hadn't. It seemed like their search went on forever but she knew they had to be thorough. Knowing that the secrets would end up with people not trusting them anymore was something they knew but now when reality hit was hard to comprehend.

…………….

"How long have they been together? How long have they been married? When did they move in together? You rang home to them because you knew what was on their answering machine!" Gibbs interrogated her when the search for clues was finished. He remembered the message on the machine. It was Kate who done the message.

"This is Caitlin and Anthony. We're not home now but leave a message and phone number we'll get back to you as soon as possible. Bye."

"They got together in April, moved in together in June and got married in July. Kate did change her last name but officially she was still Todd so that's why her name Caitlin Todd is still on the mailbox. They told me from the very beginning and McGee started to suspect something about two months ago so they decided to tell him that they were dating." Abby told him.

"I haven't found anything suspicious but something is going on. I called the director and told her about their disappearance. We're going to meet her when we get back but first we're going to see if any of the neighbours are home and hope they have seen something." Gibbs told them.

……………Back at NCIS……….

"Only one neighbour was home and she saw they were in a hurry on Sunday." Gibbs told the director and some other person she had brought with her.

"Gibbs, I need to talk to you alone for a minute." The director told him.

……………

"You know about the leaks I've told you." The director told him.

"Yes. Some people on FBI and CIA were leaking and you suspected it was the same on NCIS. You didn't want me to tell the rest of the team and I didn't." Gibbs told her.

"I know you didn't. You didn't tell anyone so we know you're not the leak." The director told him.

"How do you know that?" Gibbs asked a bit curious and worried. There were more behind those words than she let appear.

"We know who the leaks in NCIS are!" she continued.

"So there is more than one?" Gibbs asked shocked.

"Yes and you'll be surprise when you see who they are. They are a threat to the nation's security. Let's go back." The director said going back to where the rest where. Gibbs followed.

…………..

"Abigail Sciuto, you're under arrest." The director told her. Then two people put handcuffs on her and led her to an interrogation room.

"What…She would never do something like that! You're wrong. I know Abby." McGee told them.

"I can't talk about that." The director told them.

………….Outside the interrogation room………

"I think she realises the seriousness of this all and if you question her I think she will tell us all. A team is on their way to her apartment and another to the Dinozzo house."

"You're wrong. I will prove you are wrong. Tony, Kate and Abby would never do something like that." Gibbs told her.

"The hardest thing is being betrayed. I understand how you are feeling but go in there and do your job before anyone gets killed."

Gibbs listened and went in there.

"Abby, tell me what you know."

"I don't know. Tony and Kate were a little scared but they would never tell me why they were scared. They would be shocked if they knew what was going on now. I know they would never do something criminal. I know them. I was at their wedding. I know them. I can see in your eyes that you don't believe me but I know the truth…I want a lawyer." Abby told him.

"The hid so much. You hid so much. You know more. I can't believe I'm saying this but I know you know more." Gibbs told her.

"I'm not saying anything else." Abby said totally convinced over doing the right thing.

………………Not so far from NCIS………

"You did well. Your friend Abigail got arrested and she won't tell them anything. Now try out which weapons which suit you the best. We're on a mission." A man told Tony and Kate.

……………At NCIS………….

"I'm going to help out with the search of their homes. I know they didn't do it." Gibbs told his boss.

"I can't let you do it. Now that the team is corrupted it is too dangerous."

Then the director's phone rang. She answered and went away. When she came back she had some other agents with her. McGee stood besides Gibbs.

"Agent Gibbs and McGee. You both are under arrest."
