Author's Note- I was inspired last night by the 200th episode to write this. I know this plot has been done a lot (Of course you don't know what the plot is yet but trust me) but once again I felt the need to put my own spin on it. For as far as I can tell it hasn't been done this way yet but if I'm wrong, I apologize. Spoilers for episode 9x14: 'Life Before His Eyes'. Enjoy!

Chapter 1- Four in the Picture.

He had to admit that it felt good to be with his girls again but like he told Mike earlier, he wasn't done with his life yet. For now though, he was content with just sitting there with them. He peered over his shoulder to see what his little girl was drawing. The picture showed a woman with long red hair, a little girl with strawberry blond hair, a man with dark brown hair and another boy with the same strawberry blond hair as the little girl. Gibbs' brow furrowed at the picture. "Who's the other boy, Sweetheart?"

Kelly looked from her father to the picture and then to her mother. She forgot that the boy was her and her mother's secret. She shot her mother a sorrowful look but it soon turned into one of hopefulness when it seemed as though her mother was finally going to be able to tell him. Maybe it would make him happy again.

Shannon sighed and took a few seconds to collect her thoughts. As the look on his wife's face changed, Gibbs started to worry that something was wrong. Finally the redhead spoke, "I'm so sorry I didn't tell you. I just didn't want you to be mad at me."

"What didn't you tell me?" Gibbs asked, starting to get really nervous. It wasn't a bad nervous though, it was more like the nervous he felt when he proposed to her and the night Kelly was born.

"You have a son, Jethro." She said; glad to finally get it off her chest.

Gibbs froze. He couldn't believe what she had said. It couldn't be possible. Not unless… "You were pregnant when…when…"

Shannon knew where he was going but he didn't want to say it. "No before that. Before Kelly. It happened that night on the train. I was so scared and I didn't know what was going to happen with us when you got back."

"What are you trying to say?" he asked, leaning forward and grabbing her hand.

"I had a baby. A little buy. I didn't think I could do it alone so I gave him up for adoption." Tears started to fall down her face as she told him. It was still hard for her to think about, never mind talk.

Gibbs' heart began to race. He had a son somewhere out in the world. He was determined to find him when he was out of this 'dream world' like place. "What's his name?"

"Remember the conversation we had that night about your name and how you wished it was something more normal?" she asked him.

"Yes." He answered. When he was young, he despised the name his parents gave him but as he grew older he found that the name suited him.

"You said that you wished it were something like Mark, or Christopher, or Tim." She continued. "I always liked the name Timothy and you said you liked it too, so that's what I chose. I named him Timothy Jethro Gibbs." She explained.

Gibbs gut churned a little. "Who adopted him?"

"They seemed like a nice couple. He was on his way to being a Navy Admiral and she was a school teacher." She told him. She knew that he was starting to put the pieces together.

"What were their names, Shannon?" he asked, almost afraid of what the answer would be.

"Robert and Linda McGee." She admitted.

"So you're telling me-"he began but she cut him off.

"That Tim McGee is your son, our son? Yes." She said.

As she said it, the diner door opened and Kelly jumped over him and raced to the new occupant. "Tim!" she yelled as she jumped into his arms.

Tim for his part didn't even seem to be fazed by the young girl. He lifted her into his arms and spun her around like they had known each other their entire lives. "Hey, kiddo." He said smiling.

"I'm so happy to see you." She said with a huge smile on her face.

"Me to, Kells, me to." He said as he wrapped her in a tight hug. Looking over his shoulder, he smiled at the couple watching them. He put down Kelly and grabbed her hand as they walked towards them. "Hey, mom." He said, leaning over and kissing Shannon's cheek.

Shannon smiled up at her son; it felt really good to hear him call her that. Tim then turned to Gibbs, "Hey, Boss." He said to the older man like he did every morning and not like the man was his father. He then turned back to Kelly, "Come on, kid. Let's go meet some friends."

Gibbs watched as his kids walked over to the booth where Tony, Ziva and Abby sat, and then turned back to his wife. "So you're telling me that I had a son out there and have been working with him for almost nine years?" Gibbs said, unbelieving.

"I'm sorry I didn't tell you. I wanted to. Every time I watched you and Kelly, I wished I had never given him up but I couldn't go back on my decision." Shannon said tears starting to pour again.

Gibbs quickly joined her on the other side of the booth and wrapped his arms around her. "It's okay, I forgive you." He whispered as he rocked her.

Gibbs still didn't know what he was going to do about his and Tim's situation but he did know that a familiar warmness that he hadn't felt in years made its way throughout his body as he watched Tim and Kelly talk. He also felt proud. Proud that he was Tim's father. He had always been proud of Tim, seeing as though he went from the greenest agent he had seen to one of the best agents he had ever worked with.

Now that he knew, the toughest part was yet to come. Telling Tim and getting through the initial shock and awkwardness, was definitely going to be hard. It's a good thing Marine's never backed down from a challenge.
