The team was silent, today was the fifth anniversary of losing a member of their team. Every May 24th they started the day off with a moment of silence for Kate.

Today Ziva was going to give Gibbs a piece of history…something that would change everyone's life forever and everything they knew about Kate Todd.

Gibbs looked at his computer till Ziva came over. "Yeah?"

Ziva handed an envelope to Gibbs, "I'm suppose to give this to you…five years to the day Agent Todd was killed. It was with Ari when I shot him…I found it when I searched his body."

Gibbs eyed her as Tony and McGee joined her, taking the envelope, they watched as their leader opened it.

He pulled out a letter and a photo; the photo was of Kate and Ari…he was holding her in his arms and she was kissing his cheek…happy.

"We were watching him for a while…he had become a liability because of his weakness…Kate was his weakness. Read the letter." Ziva looked at them and Gibbs unfolded the letter, reading it aloud.

"Gibbs,

By now I have been dead for five years as is Caitlin…I did not shoot her, I could not…I loved her. When I heard of her death, I wanted revenge…whoever shot her stole my life. I was leaving Mossad, to marry Caitlin…for us to have a family.

She was my basherte…ask my dear sister what it means, she will know. I lasted days trying to find her killer and could not so I made the decision to allow you revenge for what you think I did. I may not have shot Caitlin but I brought her death…by having a life with her, even for those short months…I deserve death.

By now you have shot me but I am at peace, life without Caitlin is meaningless. I am sorry I brought her death but I ask you not to give up and find her real killer.

Ari Haswari."

They all looked at each other; Ziva spoke, "Ari told me he couldn't harm her…he never did just like she couldn't harm him."

"What's a basherte?" McGee looked at Ziva but it was Abby who spoke, they turned to find her.

"It's a Jewish term concerning soul mates…I'm sorry Gibbs, I helped Kate hide her relationship with Ari. At first she hated him but couldn't harm him but after a while…she said she loved him and asked him to leave Mossad for her…he said he would, she was pregnant…twelve weeks."

Gibbs stood and walked to Abby, placing his hands on her arms. "Did she say she loved him?"

"Yes, she said she couldn't live without him…she said he completed her. I'm sorry…if I had just told you like she thought I would…I got her killed."

"No Abby you didn't," he turned to Ziva, "do you think he would kill himself because of her death?"

"Yes, he was planning to leave Mossad, to leave a life he had known for a single woman. If he didn't love her, he wouldn't have left. I heard his voice when he called me…he was hurting, like his life had been stolen from him. He set himself up to be killed…he didn't want to live without her."

"Gibbs…we have to do something, Kate's killer is still out there. I have all her letters from him…he'd never hurt her. Kate said he was always gentle with her, his voice was always soft."

"I want to see those letters Abby." She nodded and left to get the letters, Gibbs looked at his team. "We have two people who are dead, one has a killer who is known but the other…we're going to find who killed Kate and that person will die."

"Gibbs," Ziva looked at Gibbs, "can we bury them together somehow…it's the only thing we can do for them now. I can have Ari ship here if you can arrange a plot for him."

Gibbs nodded and looked at Ziva, "do it."

She went to her phone and made a call, Tony eyed Gibbs.

"He said he didn't do it and we didn't believe him…how could we be so blind Boss?"

Gibbs eyed Tony and put a hand on the agent's shoulder. "Because we thought he killed her…he did but not like we suspected."

Abby came in and handed a book to Gibbs, "it's a scrapbook…I made it for her but before I could give it to her…she was killed."

Gibbs sat down and opened it, photos of Ari and Kate were on pages and beside them were handwritten notes in beautiful handwriting. "It's from first to last…but read the last first."Gibbs turned to the last page and read the letter.

Caitlin,

It is done, I am no longer with Mossad…my father has given me freedom. My Caitlin, I am returning to you and our beloved child. Keep safe my love.

Ari

"He said he was free," Gibbs looked at Ziva as she hung up her phone. "Your father tricked him."

"He would rather kill a son then allow him to betray him…I believe he ordered Kate's death…I just don't know who it was or I would have killed them years ago."

"Abby," Gibbs looked at her, "do you know what happened between them?"

Abby smiled and nodded, "Kate told me everything, well not intimate details but everything else. I can tell you the story…if you want."

"I want to hear it." McGee looked at Abby.

"I wish to hear about my brother and sister-in-law." Then men looked at Ziva, "what, Kate was going to be and the way Ari spoke about her…she was already my sister."

"I'm in too Abs." Tony looked at her and Abby eyed Gibbs, he nodded.

"Alright, it started just after Kate broke up with Tony's evil frat brother…"
