Hello again. This is my first multi-chapter endeavor into filling the void that are JJ and Will fics. Same AU that I have used in my other stories, JJ and Will, along with Henry, have twins Luke & Julia. Also Emily and Mick have 2 boys, Colin and Matthew. Had to get Emily in here given the GREAT news that she is coming back. They play minimally in this first chapter but they come about later on. I hope you enjoy.

JJ was sitting at her desk, surrounded by mountains of case files – but what else was new. She had been in the office since 8, around 3 hours when her phone chirped.

"Agent Jareau" she clipped briskly.

"Hello Agent Jareau this is Courtney from the FBI Quantico Child Care Centre."

JJ, who had been reading a file while answering the phone, quickly dropped it and gave the phone call her full attention. "Is everything okay?" she asked.

"Oh, yes everything's fine. It just seems that Luke has come down with the something. He's running a pretty high fever."

"Oh no" JJ said, "He seemed fine this morning"

"Well you know how these things can be" Courtney sympathized. And JJ did know, she swore that one minute her kids were the picture of health and the next they were beyond sick. But she knew that this was mainly because they weren't complainers. They'd wait until they were so sick they couldn't function before telling her that anything was wrong. She'd never understand that.

"And you're familiar with our policy on sick children?" Courtney continued and JJ replied,

'Yes of course. I wouldn't want him to get anyone else sick. I'll be right over to pick him up."

"Great, thanks Agent Jareau."

JJ ended the call and exited her office, thankful, not for the first time that there was a daycare on site at the FBI headquarters. She took the elevator down a few stories and exited on the second floor, making her way to the back. She pulled open the double doors and into the little reception area. A young woman greeted her.

"Hi, I'm Agent Jareau, I'm here to pick up my son."

"Hi Agent Jareau, I'm Courtney, I'm the one who phoned you."

"Oh hi."

"Luke is just here in the nurse's office." Courtney said, opening a door to the right. JJ entered to find her 3 year old son curled up on a little cot. The nurse was filling out some paperwork at her desk a few feet away. JJ perched on the cot and smoothed her hand over Luke's dark hair. Luke's blue green eyes that were identical to Will's flitted open to find hers.

"Hey buddy." JJ soothed, running her hand over his forehead. His skin felt hot under touch. "Not feeling good?"

Luke nodded. He sat up and extended his arms. JJ picked him up and Luke rested his head on her shoulder.

"He had a fever of 101.8 when I last took it about 10 minutes ago. I gave him some children's Tylenol. He can have some again in 4 hours." The nurse said softly showing JJ the bottle.

JJ nodded. She glanced out of the window in the nurse's office to see the other kids playing. She caught sight of her daughter Julia, Luke's twin, sitting around a table with 2 other little girls drinking 'tea'.

The nurse followed JJ's gaze and asked, "He has a sister here too right?"

"Yeah," JJ nodded looking back to Luke who seemed to be falling back to sleep in her arms. "I've got some stuff to finish up before we go home so I'll leave her here for a bit and then come back."

"Sure" the nurse nodded. "You'll just need to sign him out with Courtney before you leave."

JJ nodded. "Let's go Luke." She exited the room, stopping at the desk, signing him out on her way.

JJ made her way back to her office, Luke fast asleep in her arms. She laid him gingerly onto her desk chair. He curled up and fit easily on the seat. His body still felt warm, but JJ covered him with her jacket anyways. She hurried around the room, gathering papers and files she needed, stuffing them into her bag. She made two hushed phone calls and was ready to leave. She took her jacket back from Luke who was still sleeping soundly and pulled it on. She grabbed Luke's jacket off the desk where she had set it after grabbing it from his cubby on the way out. She gently slid him into it and stuffed his hat into her bag. Picking up her bag and then Luke, JJ left her office. She made her way to Hotch's office to let him know she would be working from home for the rest of the day. She knocked and entered, feeling Luke stir in her arms. Inside JJ found Hotch and Emily going over some papers. They looked up in surprise to see Luke with JJ.

"He's sick" she offered and Hotch nodded.

"You're headed home then?" he asked.

JJ nodded. "I have my phone, of course, if you need me."

Hotch shook his head. "We'll be fine. You just feel better buddy." Hotch said to Luke and JJ smiled. Luke looked directly at Hotch but said nothing. He made no attempt to even lift his head from JJ's shoulder.

"Aw, Sweetie." Emily cooed. "Are you taking Julia with you too?" she asked.

"Yeah we're headed to go get her now."

"Do you want me to take her?" Emily asked, "I can take her home with me when I pick up Matthew there later. Save you having to watch her while taking care of Luke. I can drop her off later?"

"Emily I could kiss you. Thank you, God that'd be great. And so much better for Jules than having to play by herself at home, because she and Henry are not getting anywhere near you." She added to Luke.

"Yeah, one sick kid is enough." Emily added. "Hey, actually, when I pick up Colin from school I can grab Henry for you too. Save Luke having to go for another car ride when he's sick."

"Seriously, Emily, you are my favourite person." JJ beamed. "Thank you, I will owe you so big."

"Hey, no problem."

"I'll just give them a call at the daycare, let them know that Julia is going with you, and call the school to do the same for Henry."

"Sounds good." Emily said, "Feel better pal," she added as JJ left the room.

JJ made a call to the daycare and the school from the car while Luke dozed in his car seat. Pulling into their driveway, JJ parked the car and killed the engine. She gathered her belongings in one arm and took Luke in the other. He woke up and hugged her, putting his arms around her neck and resting his head on her shoulder.

"I know Sweetie" JJ soothed as she dropped her stuff in the front hall. She used both arms to support him now as she carried Luke upstairs to his room. "Pajamas?" She asked and Luke nodded.

JJ changed Luke into his pajamas. She tucked him into his bed before heading to the bathroom for supplies. She came back with an ear thermometer.

"Let's see if that Tylenol's working bud." A few seconds later JJ was met with a reading of 101.5. "Maybe a little bit. We've gotta wait before you can have more though Hun." JJ left again and returned with a cool cloth. She wiped Luke's forehead and face. He closed his eyes and murmured.

"Feels good Mommy"

JJ smiled and continued to wipe his face until the cloth had warmed up. She set it aside before pressing a kiss to a once again sleeping Luke's forehead. She turned out the light in his room, but left the door open.

Leaving Luke's room, JJ headed to her own bedroom to change, figuring if she was going to be home all day she might as well be comfortable. She pulled on black yoga pants and a grey zip up hoodie before heading downstairs. Once downstairs, JJ decided to work on the couch. She set up with her phone, her case files and paperwork. She went to the kitchen to make herself a cup of coffee, but at the last minute decided she was actually in more of a tea mood.

JJ sat, curled up on the couch with her tea and case files for around half an hour before she heard a soft padding on the stairs. She looked up to see Luke, rubbing his face in the doorway of the living room.

"Hi Sweetie" JJ said, setting down the file she had been reading.

Luke took in the paper surrounding his mom and softly asked, "Are you working?"

JJ smiled. Her kids knew not to interrupt Mommy when she was working. JJ had made that very clear, given the types of files she often had to examine, the last thing she wanted was for one of her kids to come across a photo of something they shouldn't see. For that same reason JJ was always extremely careful to never leave a file lying around.

"Not anymore." JJ replied, closing the file and putting the whole pile of them away in her bag. "Are you hungry babe?" She asked, noting that it was 12:15. Luke shook his head. "You need to eat to get better Sweetie. Do you want some soup?" Luke shook his head. "A banana?" Luke shook his head again. "Applesauce?" JJ tried again.

"No Mommy" Luke answered. JJ rose off the couch and picked Luke up. She walked with him towards the kitchen.

"Okay" she conceded, "Just something to drink then." Luke shook his head. "Oh buddy you have to drink. You won't feel better unless you do. How 'bout some apple juice?

"No."

"A popsicle?" JJ suggested

"No Mommy."

JJ ran her hand over Luke's hair and kissed his forehead. If Luke was refusing a popsicle he had to be feeling really rotten. JJ grabbed Luke's favourite cup down from the cupboard and poured in some apple juice and water.

"No. No, no." Luke said. He shook his head and buried his face in JJ's neck. His forehead felt hot against her skin. JJ set him down on the counter and placed her hand against his forehead.

"It's been an hour and a half. You should not be this warm." JJ said, sounding concerned.

Luke ignored her comment, staying on point with what he thought really mattered. "No juice." He repeated.

JJ picked Luke back up and left the cup on the counter. She could tell he was smiling, feeling victorious. They entered the bathroom and JJ set Luke on the counter. She grabbed the thermometer and held it to his ear. It presented a reading of 102.4.

"Luke, that's too high." JJ muttered. She turned and rooted around in the medicine cabinet for a few seconds before emerging with some Children's Motrin. She brought Luke and the medicine back down to the kitchen and grabbed a spoon. Pouring out the dosage, JJ held the spoon out to Luke. He shook his head.

"Ah, No, sorry buddy, but your fever is way too high. It's this or we're going to the hospital." If this doesn't bring it down we're going to the hospital anyways, JJ thought to herself. Luke relented and opened his mouth. JJ popped in the medicine which he swallowed before making a grim face. JJ handed him the cup of watered down juice. Luke swallowed a little bit before setting the cup down beside him.

"No juice." He muttered crossly. JJ sighed. She knew that he was being stubborn now because he was cranky from feeling sick. Although she knew that the fact that he was still willing to fight with her was a good sign. If he became submissive she would be far more concerned. Knowing Luke needed to stay hydrated JJ opened a drawer and pulled out a travel sippy cup. She and Will had weaned Luke and Julia off of sippy cups a few months ago, but she kept a few around for long car rides. JJ transferred Luke's juice into the sippy cup and screwed on the lid. She extended the sippy cup to Luke. She watched as Luke was torn between wanting the cup and his desire to stay stubborn.

"Please Sweetie" JJ pleaded. Luke took the cup and popped it in his mouth. JJ picked him up and hugged him close. "Good boy" she smiled into his hair. "Do you want to watch a movie?" She asked, making her way to the living room and settling him on the couch. Luke nodded. "What do you want to watch?"

"Scooby" Luke answered.

"Which one?" JJ asked, surveying their rather large collection of Scooby-Doo movies. He was hands down Luke and Henry's favourite and Julia liked him too.

"Will you watch it with me Mommy?" Luke asked

"Of course Sweetheart."

"You pick," he said. JJ smiled and selected Scooby-Doo and the Alien Invaders. "Good choice Mommy" Luke smiled.

JJ popped in the DVD and curled up with Luke on the couch. 40 minutes later Luke was asleep with his head in her lap and JJ switched off the television. She looked to the paperwork sitting on the coffee table, but reached for her phone instead. She hit her first speed dial.

"Hi Cher" she heard Will's voice when he picked up.

"Hey" JJ said softly to not wake Luke.

"What's up?"

"I'm at home with Luke. He's sick"

"Oh no what's wrong?"

"Just a really high fever so far." She ran her hand over his forehead and it felt cooler than before. "The medicine's working. He's asleep in my lap."

"Poor thing. How're the others?"

"Jules was fine when I left her at daycare and the school hasn't called to say Henry's sick."

"Jules is still at daycare?"

"Yeah I thought she'd have more fun there than stuck at home with us. Emily is taking her when she picks up Matthew. She's gonna grab Henry from school too when she picks up Colin. I would prefer to keep them as segregated as possible from Luke."

"Yeah I hear ya" Will replied and she knew they were both remembering 2 years ago when the twins were 1 and Henry was 4 and all three of them had become extremely sick. She knew it was an experience neither of them ever wanted to repeat. "I can pick them up from Emily's on my way home. Save her a trip." Will offered.

"That'd be great." JJ said, "I'll let her know."

"Okay. Kiss Luke for me"

"I will" JJ smiled and ended the call. She placed a quick call to Emily, thanking her again and letting her know that Will would pick the kids up from her place, which was fine with Emily. She looked again to the paperwork, leaving the case files in her bag in case Luke woke up she pulled some papers towards her, and settled in for the afternoon.

Thanks for making it to the end Reviews are adored and extremely appreciated but of course, not required. Cheers.
