After dinner, Tony and Tim went to the living room to play a game. Gibbs was cleaning up the dishes. He noticed that Kate didn't eat much, almost nothing. She was still sitting quietly at the table with her hands holding her head.

Gibbs looked concerned and walks to Kate. He kneels in the front of her so he could make eye contact.

"Hey Kate, are you okay?"

Kate made eye contact with Gibbs, then shook her head.

"No." She said quietly. " I just have a headache and feel nauseous."

Gibbs frowns. He puts his hand on her forehead. Mhmm no fever he thought.

"When did this start?"

"When I was outside with Tony but it wasn't that bad like it's now."

"Come, lets put you in bed so I can give you something for the headache. Then I will give Ducky a call"

"Don't need to do that Gibbs. It will pass."

"No arguments darling." He picked her up from her seat and carried her upstairs. He could see how tired she was.

"Don't need to carry me. I'm too big. I can walk." She laid her head on Gibbs shoulder.

"Don't worry about that. You're sick. I take care of you."

When Kate was in her bed, he gave her the painkillers. She laid back down and she was almost asleep immediately.

Gibbs runs a hand through her hair and kissed her goodnight.

In the hallway Gibbs looked at his phone deciding if he should call Ducky. Ducky was still at work. He promised he would come to the house when he was done.

It looks like it was just the flu. He decided to wait to call Ducky, maybe she would feel better now that she had the painkillers like Tim did earlier. He felt better this afternoon. He only hoped the nausea was there because of the headache. She was walking with that for like 4 or 5 hours. Well maybe the sleep will help. He walked downstairs to see what the boys were doing. He heard laughing. Laughing was always good.

"What's are you boys up too?" Gibbs asked smiling.

"We are playing this funny game Gibbs want to join us?" Tony asks still laughing.

"Is Kate alright? She didn't seem to look so good." Tim asks concerned when he thought back.

"She didn't feel so well. I gave her some painkillers and she is asleep now maybe that will help." Gibbs said.

"Is Ducky coming?" Tony asked.

"Ducky is still working. He will be here when he's done. Now tell me what game you're playing."

Tim begins to explain the game to Gibbs. After playing for a hour they decided that they had enough. So now they were sitting on the couch watching a movie. Gibbs was in the middle with the two boy cuddling next to him.

All of a sudden Tim jumps off the couch and runs to the bathroom. Gibbs immediately ran after him to see what was wrong. Tim was vomiting in the toilet. Gibbs runs a hand up and down his back. His other hand was on Tim's forehead. He was running a fever. "It Okay Tim. Just relax. It will be over soon." Gibbs said trying to comfort him. Tears were running down his face.

After the vomiting had stopped. Gibbs gave him a glass of water to rise his mouth. Then he picked Tim up and carried him out of the bathroom. He met Tony in the hallway with a concerned look on his face.

"It's okay Tony. Why don't you watch the movie while I bring Tim upstairs. He is not feeling so well." Gibbs said.

Tony nodded his head but didn't say anything and went back to the couch.

Upstairs Gibbs was changing Tim in his pjs and gave him something for his fever.

"I'm sorry Gibbs didn't mean to do that." Tim said softly.

"You don't have to say sorry for something you can't control buddy. Why don't you get some sleep. I leave a bucket by your bed. Hopefully you feel better soon." Gibbs said while running a hand through his hair before giving him a goodnight kiss.

Thank you Gibbs. Goodnight." That said Tim went to sleep.

Gibbs stands up and walked to the hallway and runs a hand through his own hair. He now had two sick children. He needed Ducky! But first went to check on Kate again and see how she was doing before he called him.

She was not sleeping as peacefully as he thought. Tossing in her bed. Sweat was dripping down her face and neck. Shaking her head from side to side.

"Kate come on wake up for a moment" Gibbs said shaking her a little bit to wake her up. She had fever alright. "Come on Kate I need you to take something for your fever and drink something."

Kate finally opened her eyes and followed Gibbs instructions. She then went back to sleep. Gibbs put a wet cloth on her forehead before he went back to the hallway.

This was not good. Halfway down the stairs Gibbs starts to call Ducky.

"Ah Jethro what can I do for you? I'm almost done here. Is something wrong?"

"Duck I need you to come back quickly. Tim and Kate are sick. Fever, headache, nausea, Tim already vomited. They already had a painkiller and something for their fever but I don't know what is wrong. How did they get sick? They didn't eat anything wrong!"

"Don't know Jethro but I will come right now so I can exam them. How is Tony? Did he had any symptoms?"

Gibbs was now downstairs and walked directly to the living room.

"No he was fine he ..."

"Jethro? Jethro what is wrong!"

When Gibbs saw Tony curled up in the corner of the couch he knew something was wrong.

Gibbs kneels in the front of him and put a hand on his forehead. He was warm.

"Duck Tony is also sick. Just now. He has a fever what I can tell. I need you to come quick. Maybe this is something from the liquid in that explosion?" Gibbs said worriedly.

"I'm already on my way Jethro. I will be there in 10 minutes." Ducky said and put the phone always.

Gibbs was now sitting next to Tony trying to uncurl him and put him on his lap.

"Tony hey what is wrong? You hurt somewhere? Feeling sick?" Gibbs asked kindly.

Tony was now clinging into Gibbs shirt and snuggles deeper in the warm comfort arms who were holding him.

"Headache" Tony said softly.

"Anything else ..."

Gibbs suddenly heard the door opening. He had the lock now on because of the kids. Ducky and Abby were the only ones that had a key to his front door besides himself.

"JETHRO, I'm here." Ducky said when he stepped inside.

"In here Duck. Thank god you are here."

"Ah I see young Anthony is the only one still here."

"Yeah Duck, Kate and Tim already went to bed. Kate was the one who was sick at first. 1,5 hours later Tim runs to the bathroom and was also sick and when I had you on the phone Tony became sick."

"I'm not sick" Tony said softly.

"You got a headache and fever Tony. You are sick." Gibbs said and looked Tony in the eyes. He shifts him so he was facing Ducky.

"Maybe it's something they ate. What did you have tonight?" Ducky asked who was already starting his examination of Tony who was trying to get away but Gibbs arms kept him secure.

"Can't be Ducky. I'm not sick and Kate was already sick before we had dinner."

"Anthony can you lift your shirt up so I can listen to your heart and lungs?" Ducky asked. Trying to get the boy to cooperate.

Tony shook his head no. And tossed his head back on Gibbs chest. Trying to snuggle deeper and higher on Gibbs chest and turned his head so he wasn't facing Ducky.

Gibbs lifts Tony's shirt up and hold his arm high over Tony's chest but keeps space so Ducky could still work. His arm was keeping Tony still and secure but his shirt was also lifted. He runs his thumb up and down Tony's arm. His other arm was around Tony's waist. Whispering soft comfort words in his ear. Trying to get the boy to cooperate for Ducky but also let him know that no one is hurting him all what they were trying to do is to help him. He could feel the fear running through Tony's feverish body.

"I'm all done Anthony. Try to relax my boy." Ducky said kindly.

Tony was now hugging and clinging to Gibbs. He couldn't help it. Try to relax was easier said than done. Gibbs was rocking him so he would calm down.

"It's okey Tony all done now."

"Jethro I got a pill for Anthony to take. It will bring his fever down."

Gibbs took the pill from Ducky. "Tony open your mouth for a minute. I need you to take this pill."

Tony follows Gibbs instructions. "good boy now take some water than I will bring you to bed so you can sleep."

Gibbs stands up with Tony in his arms and brings him upstairs. Ducky was following them to the boys room with his bag in his hand.

While Gibbs was changing Tony in his pjs, Ducky decided to check out Tim.

When Tony was asleep Gibbs went to Ducky's side to help.

"His fever is a little down so the medicine is working Jethro".

"Good to hear Ducky, two done one to go".

"Yes Jethro shall we go to Caitlin?"

"Let's go"

Kate was sleeping more peacefully than the last time Gibbs came to check on her.

Ducky was already by her side to check her out.

"Her fever is also down Jethro. Why don't we go downstairs so they can rest." Ducky said.

Gibbs nodded.

Downstairs Ducky and Gibbs were sitting at the kitchen table. Gibbs drinking a coffee and Ducky his tea.

"So Duck what do you think is wrong?"

"Honestly Jethro all I can think about now is a bug. It will pass."

"And if it's not a bug but more to do with why they are kids?"

Ducky sighs. "I just don't know Jethro if it has something to do with the de-aging, maybe they will age again like last time."

"But they didn't got sick the last time Duck. They all got the same symptoms. The oldest starts and ends with the youngest. Something is wrong we're missing something."

"I don't know what to say Jethro. The only thing that I could do is to take a blood sample again. But I don't think that we find anything. Remember we already took blood twice. I doubt that we find anything. And to be honestly I don't want to frighten Anthony more than I already did today." Ducky said sadly.

"It wasn't you he was frightened of Ducky. Something from his childhood. He still don't want to talk about it. But I know for sure it wasn't you. He isn't frightened when you are around him. He even hugged you. It's just the medical part he isn't so keen of."

"I hope Anthony will talk about it someday. Maybe then we could help him."

"I hope too"

"Still I think we shouldn't do the blood test. We just wait and check up on them through the night."

"Okay Duck. Your call."
