Ducky and Gibbs checked up on the kids through the night. After 5 am they decided that it was safe for them to go to bed so they could get some sleep.

The kids were sleeping peacefully and the fever was gone.

9 am Gibbs was awake. He didn't hear any movement. Probably because they were still sleeping. So he decided to shower first and after that he would check on the kids.

"HOLY SHIT!"

Gibbs was already out of the shower and was putting on some clothes when he heard a man's voice yell. He quickly put on the rest of his clothes and grabbed his gun. He needed to protect the kids.

In the hallway Gibbs had his gun still raised up. He follows the voice that he was hearing.

"HOW!"

Gibbs heard the voice clearly now. It came from the boy's bedroom. Shit, why didn't he stay awake. Choice easy made Gibbs pull the door open and aimed his gun at his target.

"NCIS DON'T MOVE!" Gibbs yells but soon his eyes enlarges.

"BOSS!" Two voices said.

Gibbs put his gun down immediately. A moment lost for words.

"You are big again" Gibbs finally said.

"Yeah we noticed!" Tony said stating the obvious.

"Don't be smart with me young man" Gibbs said as he pointed a finger at Tony.

"Young man? Boss I'm not a little kid anymore." Tony said.

Tim laughs. "You sure about that?"

"Hey I can still fight you. I can ..."

"ENOUGH! We still don't know what happened. Are you two okay? How are you feeling? You still got a headache?" Gibbs asked in father mode. Putting a hand on both their foreheads.

"Boss we are fine" Tony said as he tried to get away from Gibbs hand on his forehead.

"Yeah boss nothing wrong" Tim said.

"OMG!" The men heard.

"Well looks like Kate is awake" Tony said smiling.

"And noticing that she is an adult again" Tim added.

Soon Kate was in the room with them.

"You are big again too" Kate said in disbelieve.

"Yeah Kate we noticed." Tim said.

Gibbs gave Kate a hug. Trying to calm her down so that she knew that this was reality. "How are you feeling Kate?"

"Little overwhelmed actually."

"Well let's go downstairs so we can have breakfast and talk." Gibbs said. Kate, Tim and Tony nodded.

"Why don't you set the table while I wake Ducky" with that said Gibbs went to Ducky's bedroom.

He knocks on the door. "Come in" he heard.

"Ah good morning Jethro. What brings you here? Is something wrong with the kids?" Ducky asked concerned. Ducky had already showered and was already dressed for the day.

"No they are okay I think. I mean they are grown up again."

"How old are they now. Are they having symptoms from last night?"

"No Ducky, I mean they are adults again. They are their age they are supposed to be."

"They are adults!" Ducky asked stunning.

"Yeah that's what I said Duck!"

"Why didn't you say, why are we standing here for then." Ducky walks out of the room to the kitchen.

Gibbs sighs but soon followed Ducky to the kitchen where he met his agents.

"Oh my you have grown, haven't you." Ducky said when he saw them.

"Hey Ducky, yes we did" Kate said smiling.

Ducky kept staring at the three of them. Then shakes his head. "How are you feeling? Any nausea or headache? How about the fever?"

"We are fine Ducky, really" Tony said.

Gibbs was watching the scene in the front of him. He couldn't help the smile that was on his face.

"Why don't we sit down and eat our breakfast?" Gibbs said. Everybody nodded and sat down.

"So did you find out what was in the liquid?" Tim asked while eating.

"No, when the test Abby was running was done, we already knew what the effect was. We couldn't find a serum or when or if the liquid could be stopped" Gibbs said.

"When you were sick last night we got pretty worried. I couldn't found out what was wrong with you. And we didn't had answers to what to expect. I'm glad to see you all so well. But I still want to check you out to be sure."Ducky said.

"But we are okay now Ducky. We are adults again." Tony said.

"Well some of us are" Kate said softly.

"What's that suppose to mean?" Tony asked angry. He knew this would come back one day.

"Well you lied about your age, so basically you're still a kid now that we know your real age" Kate said smiling.

"Yeah so I lied. What is your problem. I still ..."

Gibbs laid a hand on Tony's shoulder to calm him down. Tony looks in Gibbs eyes who was telling Tony to keep calm and he would handle it.

"Kate" Gibbs said when he saw that Kate would open her mouth to say something else. It was only teasing he knew. Siblings would do that. But this subject was still too sensitive for Tony to discuss. He would talk to Kate about that after breakfast.

"So what will happen now?" Tim asked when everyone was calm again and had eaten their breakfast.

"I think it's best to start examining you. To see if we didn't miss anything. Then I will take a blood sample and bring it to Abby." Ducky said.

"Tim you go first. Tony go upstairs and take a shower while Kate and I will clean up the dishes." Gibbs said.

"Well come on Timothy. I will exam you in my bedroom." Ducky said and walks with Tim to his room.

Tony looked at Gibbs, but when he saw the look Gibbs gave he said. "Sure boss" and went upstairs.

That left him and Kate alone in the kitchen.

"Kate what do remember when you were a kid?" Gibbs starts to ask.

"I remember everything Gibbs. Why do you ask?"

"Because of what you said to Tony at the kitchen table."

"What has that... I was just teasing him. We became siblings Gibbs that is something I'm sure I remember. Teasing is something siblings do. At home we did it all the time. I didn't think he would become upset about it."

"I'm sure you didn't mean anything by it Kate. I just want you to understand something. Something I just noticed when I saw that he became upset."

"Oh what was that?" Kate asked looking confused.

"Remember what we found out about his childhood?"

Kate nodded. Yes, she remembered. It broke her heart. He was so little.

"I think there is a connection between his childhood and why he was a fast student"

Kate looked at Gibbs, she too found the connection now.

"He probably was studying all the time. He didn't have toys and he couldn't get away from his father. So he was studying so hard so he quickly graduated so he could avoid his father and get out of the house" Kate said realizing what she had said. How could she be so stupid.

They suddenly heard somebody clapping in his hands behind them. They saw Tony standing in the doorway.

"Well done Kate, you made the connection."

Gibbs looked concerned. He didn't want Tony to hear what he discussed. He knew it would upset him if he thought that people were talking about him behind his back. He wanted to say something but Kate beats him to it.

"Tony I'm so sorry. I .." Kate begins to say.

Tony holds his hand up to stop her.

"I don't blame you Kate. I shouldn't have behaved like that. Like you said. It was just teasing like siblings do."

"But.."

"Kate trust me. It just too fresh in my mind now. I didn't know that I would react like that. If I didn't knew then how could you even know. It just too .,"

"Soon." Kate finished. "I understand Tony. And I'm sorry you had a childhood like that. It couldn't be easy." She walks to Tony and gave him a hug.

"That is an understatement" Tony laughed while holding Kate in his arms. He gave a look at Gibbs to say that it was okay and he understood why Gibbs went to talk to Kate about it. He probably couldn't do it himself if he was honestly.

"But remember one thing Tony'."

"What is that Kate?"

"You are still the little brother. So you will be smothered, teased and protect by your older siblings." Kate said smiling.

"Haha, I remember, but also remember that I'm taller than you." Tony said teasing but still smiling.

"Doesn't matter Tony you're still the little brother" Tim said when he came into the kitchen. He heard the last sentence of what Kate said.

"You two are funny" Tony said.

"Believe it Tony welcome to siblings hood" Gibbs said. Glad everything was forgiven. "Kate your time to go to ducky"

"Okay, see you later" Kate said before she went to Ducky's room.

Tim gave Tony a one arm hug. "She is right you know" Tim said laughing.
