I've wanted to do an AU CM fic for a while. I've read a couple of great ones with members of the BAU as children and really wanted to try one of my own. This is simply for fun and not to be taken too seriously. Oh and Will mostly annoys me, so for this story pretend he and JJ decided to remain just friends and he is still in New Orleans and he comes up and visits Henry periodically and Haley has already died. Hopefully, you enjoy:)

"It is never too late to have a happy childhood."

-Tom Robbins

Hotch simply stared. He wasn't one usually at a loss for what to do in any situation, he was the leader of the team after all but...he simply stared.

"Hotch?" Morgan's voice crackled in his ear. "What's going on man? Rossi and I are coming in through the back. You guys good in there?"

"Um...not really." JJ answered for him. She was standing next to Hotch and her face mimicked his own, open mouth in shock.

"Guys? Seriously? What? We're on our way. Are Prentiss and Reid okay?"

"That depends." Hotch finally found his voice.

"On what man! We heard shots!" Morgan's voice grew angry and Hotch didn't blame him, he simply had no idea how to explain the situation. Hearing footsteps behind him, he realized in a moment he wouldn't have to. Rossi and Morgan would have to see it for themselves.

"Aaron what is going..." Rossi trailed off as he took in the sight before him. "What the..."

"Fuck?" Morgan finished for him. The dark man dropped his gun and stared, looking back and forth between JJ and Hotch for clarification, but receiving none. "Who are those kids? Where are Prentiss and Reid?"

"Those kids are Prentiss and Reid." Hotch finally said.

"Come again?" Rossi asked calmly.

"They were right ahead of us, they entered and we began to clear the room. Wilson came up behind them and injected them both with something. We fired and he went down, he's dead but they...well, we blinked and that happened." JJ said, baffled. As she spoke the two young children in front of them began stirring. All of it had happened so fast no one really knew what was going on. The brunette sat up and blinked a few times, trying to get her bearings straight. Once she caught sight of everyone, she began to rise, watching as everyone looked at her oddly.

"What?" She accused. Morgan's jaw dropped and she frowned. "Why does my voice sound weird? Why are you all staring at me?" She froze. "Why did my pants just slide down?" She squeaked.

"You're a child!" Reid exclaimed in a tiny high pitched voice. Looking down at himself his voice rose an octave. "I'M A CHILD!"

"WHAT THE HELL IS GOING ON!" Emily screamed furiously, trying again to stand but tripping on her too long pants and falling onto her face.

"We're not sure, we need...Dave, call an ambulance."Hotch ordered.

"And tell them what?"

"I have no idea, but he injected them with something and clearly, this is not normal and we have no idea what its doing to them." He said in a lowered voice.

"I am not getting in a fucking ambulance." Emily growled. JJ winched at the oddness of the harsh words coming out of someone who looked like she was six or seven years old. Hotch hesitated a minute, even with everything that was happening, Emily managed to look tough as a child. "Hotch." She growled again.

"Fine, we'll take them to the hospital ourselves. Rossi, stick around and help the locals with the body and the rest of the scene, then meet us at the hospital." Hotch ordered. Rossi nodded and headed downstairs. Hotch turned back to his other agents and sighed. "Um...let's go."

Emily and Reid tried getting up to walk, but both tripped over themselves multiple times. "Oh for christ sake." Morgan muttered and moved to pick Emily up.

"I will break your fingers." She hissed. Smartly, Morgan pulled back and lifted Reid into his arms, despite the boy's angry protests.

"Kid, shut it." Morgan ordered. Reid pouted, but allowed himself to be carried downstairs and outside, knowing it would have taken him forever until he was in clothing that fit his current body.

JJ shot a glance to Emily and the brunette groaned as she tried to walk yet again and tripped. "Fine." She muttered. JJ bit back a smirk and easily swooped Emily up into her arms, surprised that she was quite light. "This is mortifying." Emily moaned, dropping her face into JJ's neck as they made their way outside.

"I think its kind of funny." JJ said with a smile. Emily pinched her side hard. "Ouch! Em! I will drop you!" JJ threatened.

"I'm a child!" Emily yelled, half in protest and half just in horror at the situation.

"We'll get it sorted out." JJ said softly and deposited Emily into the back of the SVU with Reid before climbing in next to her. Leaving the other car for Rossi, the three of them easily fit in the back with two of their agents now considerably smaller than they had been half and hour ago. Hotch quickly turned the car on and pealed out, speeding to the hospital.

"This is like physically impossible." Morgan muttered from the passenger seat.

"Obviously not." Reid stated matter of factly from behind him. "Clearly he made scientific discoveries as we are now in children's bodies."

"Shut up Reid." Emily said, angrily folding her arms across her chest.

"Don't be mean Em." JJ chastised her involuntarily. Emily only pouted further.

"This is insane." Hotch whispered to himself. They quickly parked and ran into the hospital, ignoring Emily and Reid's protests as they were once again picked up and carried. "We need some help." Hotch said to the nearest doctor. He explained the situation and Morgan handed over the syringes he had picked up from the floor. Clearly shocked, the doctors took Emily and Reid away to check them over while the three other agents sat down, exhausted, confused, and worried for their friends. "This is insane." Hotch repeated.

"This is fucking nuts." Morgan corrected him. JJ nodded and leaned her head back against the wall. The three of them waited, Hotch and Morgan paced while JJ sat very still. Rossi walked up to them about forty minutes later, coffee in his hands.

"Oh thank god." JJ moaned as she took her cup from him.

"Any news?" He asked.

Morgan shook his head as his phone rang. "Shit, its Garcia. She's gonna flip."

JJ noticed the doctor coming towards them with Emily and Reid, still looking very much like children, now donned in hospital gowns and each with a lollypop. For some reason, this both highly amused her and warmed her heart a little. They looked adorable. "Morgan, maybe hold off on her a minute." She said. He caught sight of them and nodded, hitting the silencer on his phone and walking over to the doctor.

"Are they alright?" Hotch asked immediately.

"Physically, yes, they are perfectly healthy." She began as Emily and Reid sat down in the seats and ignored the adults completely. Too absorbed it tearing open their suckers. "We've sent the syringes for testing, there was some residual liquid left in both of them, combined, there is enough to test."

"There were more chemicals at the scene, I've brought everything." Rossi said, holding up a bag. "I had the officers take note and catalogue it all already. So its all yours."

"Thank you, that will be very helpful." The doctor said, smiling at him and taking the bag. "Unfortunately, as you can see, this is a highly usual situation." Leading the adults out of Emily and Reid's earshot, she lowered her voice. "They appear to be around the ages six and four, both seem to hold all knowledge and memories of their adult life, but their impulses are very childlike."

"What does that mean?" Morgan asked, shooting a worried look back at his friends and feeling his phone vibrate again. He hit silent seeing Garcia's name pop up again.

The doctor sighed. "Children react more on natural impulses. They can only focus on so many things at a time, they can bounce back from things quickly, they get tired easily, etc. While Agent Prentiss and Agent Reid both retain all the knowledge that they've had, they are going to act like children their ages normally would as well."

"That makes no sense." Morgan said in frustration. "Can you fix it? Change them back?"

"We can't do anything without testing the information your...unsub? Is that what you call him? Had. It could do further damage and we don't know what we're working with. In the tests we've done with them so far, they are healthy. We'll call you the second we know anything more, and if you see any signs that there is something wrong, bring them back in...until them..."

"They're going to be children?" Hotch asked.

"I'm afraid so." She nodded grimly. "And while they may think like adults, and want to be treated like adults, they are not quite adults and shouldn't be allowed to live on their own. They are going to act more like incredibly smart children rather than their usual selves."

Hotch sighed and shook her hand. "Thank you."

"I'll call the minute I know anything more." She assured them, then walked away with the bag.

"Well, this sucks." Rossi stated. Morgan gave him a harsh laugh and groaned as his phone rang again.

"Hi Baby girl." He said gently.

"DEREK MORGAN YOU HAVE BEEN IGNORING MY PHONE CALLS! I WANT TO KNOW WHAT IS GOING ON RIGHT NOW!" Garcia's voice screamed though the phone. JJ couldn't help but smirk at the wince on Morgan's face as he pulled the phone away from his ear.

"I'm sorry, we we're talking to the doctors."

"DOCTORS! WHO'S HURT? ARE THEY OKAY!" Garcia screamed.

"Calm down, yeah they are, sort of. I'll, I'll explain it all just calm down." Morgan nodded to Hotch and stepped away from the group to talk to her.

Hotch glanced at JJ and Rossi and al three of them looked down at Emily and Reid. Emily was kicking her feet back and forth impatiently and Reid was trying not to fall asleep on her shoulder. Being six seemed to make Emily cranky and she kept pushing Reid's head away in annoyance. He looked ready to cry. "What are we gonna do with them?" JJ asked Hotch.

"They're going to have to stay with us, we can't leave them alone." Hotch said. Morgan walked back over to them with a grim look on his face.

"She's simultaneously freaking out and really excited to play with them." He said with a tight laugh. "So, you and JJ taking them?"

"What?" JJ asked.

"Well, you guys have kids..." Morgan said before trailing off at the look on JJ's face. "Dude, I am not taking care of Reid." Morgan protested.

"Do not look at me." Rossi said firmly.

Hotch and JJ shared glances and sighed. "We'll take turns." He stated mostly to Morgan. "We have no idea how long this will go on. I'll take Reid, you take Emily?" He asked JJ. She nodded.

"Reid!" Emily yelled as his head dropped onto her for the fifth time. Clearly, they were both cranky and tired. It was almost midnight.

"Should we head back to the hotel, or the jet?" Rossi asked.

"Let's just go to the jet. We're already packed, Garcia can check us out over the phone right?" Hotch asked. Morgan nodded and sent a quick text to Garcia before calling the pilot. Hotch walked over and picked Reid up just as Emily wound up to hit him and glared at her. Sheepishly, she sunk into herself, remembering that she was an adult and knew not to hit her friends.

"They can't fix us can they?" Emily asked in a soft voice.

JJ bent down in front of her. "No, not yet, they've got to test the chemicals first." She tried not to talk down to Emily, knowing that would piss her off. It was hard when she looked so little and scared. "You can stay with me and Henry for a while though!" She smiled.

"Ughh this is really gonna suck." Emily moaned as she dropped her head roughly against JJ's shoulder. JJ smirked and didn't take the statement personally. She chose to assume that her friend meant being stuck as a child rather than not wanting to stay with her. JJ took her hand and led Emily out to the car.

Reid had fallen asleep, but Emily was adamant about not seeming like a child and was desperately trying to stay away. Both Morgan and JJ tried to convince her to stop as they were tired themselves, but she wouldn't listen to them. Apparently she was much more stubborn as a child than she was as an adult, and that was saying something. By the time they boarded the jet and took off, Rossi and Reid were out cold. Morgan gave up on helping JJ, pulled his headphone's over his ears and passed out as well. Hotch went back to paperwork despite the look JJ gave him and the blonde tried to get Emily to lay down but she refused.

"Fine Em, but I'm going to sleep." JJ said pulled a blanket over herself, setting up a pillow and leaning against the window. Emily crossed her arms and sat up straight next to her, staring across at Morgan. She felt an overwhelming urge to draw on his face while he slept and wondered where the hell that had come from. It was her last thought before she finally broke down and fell asleep.

When Morgan woke up he looked across the seats and smiled. JJ was curled up against the window, Emily had fallen asleep practically on top of her. It was actually really cute. He whipped out his phone and snapped a picture, knowing he could tease the brunette with it later on. He sat up further and caught Rossi watching him. "Oh come on man, its funny."

Rossi waved his hands. "I didn't say anything."

"Yeah, you were not saying it real loud. What time is it?"

"Five am. Plane just landed. I want to still be asleep."

"God, me too." Morgan groaned, but stood up and gave JJ a gentle shake, trying not to wake up Emily.

"Go away." JJ groaned without opening her eyes.

"We're home." He explained. She kicked her foot out at him and he dodged out of the way.

Hotch walked back into the plane, having already loaded his and Reid's bags into his car. "No one has to be in until after noon; we're going to have to explain the situation to Strauss."

"Shit." Morgan groaned. "I didn't even think about that."

"Yeah, its not going to be pleasant, I suggest you all go home and get some sleep." Hotch said as he bent down to pick up the still sleeping Reid. He easily shifted the now little boy into his arms and made his way down to his car with a final nod to his sleepy team. Rossi nodded to them both and went out to his own car.

"Jayje, want me to carry her?" Morgan asked as he stretched his arms. JJ rubbed her eyes and shifted a little before realizing Emily was sort of on top of her.

"If you don't mind."

Morgan shook his head and picked her up, shifting her onto his hip and slinging his bag over his other shoulder before following Rossi down the steps. JJ sat up quickly, grabbed her bags and Emily's and headed down after him. Morgan loaded Emily into the car, stuffing her into Henry's car seat. "Need anything else?" He asked.

"No, thanks Morgan, see you later."

"Night."

JJ shook her head and tuned the radio on low in an attempt to wake herself up a bit more and drove home. Will had come up for the week to stay with Henry and she had already called him before the jet had taken off, explaining the situation. He hadn't quite believed her, and she didn't blame him. One of her best friends was currently small enough to fit – albeit not comfortably – into her son's car seat. She could see her in the rearview mirror, yet she was having a hard time believing it.

JJ cut the engine and yawned, trying to decided where to set Emily up for the rest of the night, Will was sleeping in her guest bedroom, he always did when he stayed with Henry. She was afraid if she left Emily on the couch downstairs she would either wake up disoriented and confused, or Henry would come running down and wake her up and it would freak him out. She finally decided just to toss Emily in with her. She was too tired to bother worrying about it anymore. Leaving her bags in the car, she got out and unbuckled Emily. The brunette stirred a little but JJ rubbed her back and shushed her, thankfully, it worked, just as it always did with Henry. Emily snuggled into her and she locked the car, happily walking inside. She carried Emily upstairs and gently plopped her down onto the large bed, not bothering to do anything but remove their shoes and pull the covers over them. She had already set her alarm for 9:30, and she closed her eyes happily.

Hotch lifted Reid up and carried him inside his apartment. Careful to be as quiet as possible not to wake up Jessica or Jack. He set Reid down onto the couch, took off his shoes and pulled a blanket over him. Locking the door, he shuffled back down to his room and climbed into his bed, hoping to get at least an hour or two of sleep.

Someone was sitting on top of his chest.

Hotch's eyes fluttered open. "Hi Daddy!" Jack whispered excitedly. Hotch rolled his eyes over and caught a glance at the bedside table clock, it was 8:19. Well, he'd almost gotten three hours. "Daddy, there is a boy on the couch." Jack announced.

"Yeah, I know buddy, that's Spen...Reid, that's Reid. He's going to be staying with us for a little while."

"Cool! Reid like Spencer you work with's last name?"

"Yep, a lot like that." Hotch said with a small smile. He didn't want to even try to explain anything to Jack. He would simply have new friends named Reid and Emily for a little while. Hopefully, that would suffice for the six year old.

"He's staying for breakfast?"

"And for a few days."

"In my room?"

"If you don't mind, we've got the air mattress."

"Like a sleepover for a lot of nights?" Jack asked, his face glowing with excitement.

"Yep."

"Awesome!" Jack leapt from his position on Hotch's chest and cheered. "Aunt Jessica! He's staying! Wake him up!"

"No!" Hotch said, getting up and following Jack. "Let him sleep...oh hey Reid." Hotch waved good morning seeing that Reid was already sitting up and awake.

"Hi Hotch." He said frowning as he realized he was still in his hospital gown.

"Are you sick?" Jack asked.

"No, he's not sick, do you think Reid could borrow some of your clothes for today Buddy?" Hotch asked.

"Sure, come on Reid." Jack said, grabbing his hand and yanking him down the hall. Hotch shot Reid a grateful look as he was pulled away. It was kind of funny how much smaller he was than Jack.

"Wow." Jessica said after they had gone. "So...I mean...you know what, I don't really know what to say. It happened to Agent Prentiss too?"

Hotch nodded. "None of us really know what to say." He moved over to the kitchen and began making breakfast. "Not even the doctors, they're still running tests."

"What did your boss say?"

"We'll find out in a few hours." Hotch said with a grim smile.

"Oh, well have fun with that." Jessica smirked, knowing what Hotch had told her about Strauss.

"Oh, thanks." Hotch said sarcastically. Jack and Reid ran back into the kitchen and climbed up onto the stools. Reid looked hilarious as Jack's clothes were a little too big for him. He was going to have to get Reid some new clothes of his own. Or, he would make Garcia, that would probably be a job she would love. He was thinking his decision to take Reid over Emily was definitely a good one. Reid was probably much easier to handle and all of his facts were just as interesting – if not more so – to Jack as they were when he had been an adult. Having Reid around was actually making Jack easier to handle. Sometimes he was grumpy in the morning. Once they'd had breakfast, Jack forced Reid to play with him – to which thankfully he complied – and Hotch took a shower and got everything in order for his meeting with Strauss. Jessica headed back to her apartment while Hotch piled Jack and Reid into the car. They dropped Jack off at school and Hotch and Reid drove to the bureau.

"You know, considering my current height and weight it would be much safer for me to ride in a car seat like Jack. If we were to get into an accident right now, the probability of my death would be highly likely."

Hotch sighed. "Reid, if you stop talking about it, I'll find one of Jack's old ones and put it in the car okay?"

"Alright. We'll need to find one for Emily too, she's also much to small to ride safely without one."

"Why don't you tell that to JJ once we get inside?"

"Good idea!" Reid said as he climbed out of the car. Hotch rolled his eyes and followed after him, giving a nod to Rossi and Morgan as he headed up to his office. Reid ran right over to his desk without a second thought and began filling out his paperwork for the case. Morgan watched in awe. "What?" Reid asked as he looked up.

"Nothing Kid, I just...well I kinda forgot." He admitted.

Emily and JJ walked in from the elevators and a very grumpy looking Emily stalked over and sat down at her desk. "This blows." She announced.

Morgan smirked. "Hey Princess."

"I have no qualms about punching you Morgan." The tiny girl growled at him.

"It probably wouldn't hurt with your tiny little arms." He teased.

"Morgan!" JJ scolded. She gripped the back of his neck tightly and he winced. "Today is really not the day. If you make her mood get worse, I will make you take her home tonight instead."

"I take it Miss Prentiss is not easy as a child." Rossi asked, with a laugh. He instantly wiped the smile off his face once JJ shot him a look.

"She's a freaking dream." She said sarcastically.

"Hey!" Emily pouted. "I am not bad!" Her lower lip quivered and everyone froze. This whole, they were adults but not quite thing was hard to judge. Right now, Emily looked very much like a six year old on the verge of a breakdown.

"No, I never said that Em." JJ said her voice switching maternal in an instant. "We just had a rough start right?"

"That was Henry's fault! Not mine!" Emily protested. "I didn't know he was gonna jump on me! It hurt! I'm littler now!" Emily began to cry, and then was instantly embarrassed at the fact and ran into the bathrooms.

"Shit. Tell, Hotch we'll be back in a few." JJ said and took off after her. "Emily?" She knocked on the only closed stall. "I'm sorry."

"No I'm sorry." Emily's muffled answer came back through the stall. "I feel like an idiot. I was horrible to you and Henry and Will this morning. Its just...I was really hoping it was all a bad dream and then...it wasn't. And I can't control this and I feel like a six year old and I hated being a kid when I was a kid! I hate it even more now!"

"We know Em, I'm not mad. Neither was Will or Henry, somehow we'll figure this out okay?"

"I fucking hate this!" Emily yelled as she wrenched the stall door open and another female agent walked into the bathroom. Mortified, Emily instantly went back into the stall.

"Wow, a mouth on that one huh? I thought you only had a son Agent Jareau."

"Umm...yeah she's not my daughter." JJ wasn't sure if other agents were going to be informed on the situation or not. Hotch hadn't briefed them on what to tell people yet. "Come on out Em, we've got to go." Praying Emily would listen to her adult side or whatever and just come out she waited. Thankfully, Emily opened the door. Without looking at the other agent she quickly walked over to JJ and tugged on her shirt trying pull her out.

"Your niece?"

"Hum." JJ let the agent take that however she wanted, and followed Emily out of the bathrooms and up into the conference room. The rest of the team was already gathered, including Garcia who was making a very large fuss over Reid. Once she caught sight of Emily, she squealed. Before JJ could stop her, she lunged and pulled the brunette into a crushing hug.

"Garcia!" Emily yelled, trying to shove the bubbly blonde away.

"She almost suffocated me." Reid stated somewhat proudly as Emily groaned.

"Oh my god."

Everyone froze, recognizing Strauss' voice. Garcia released Emily and Strauss got a good look at the two of them.

"That's really Agents Prentiss and Reid?" Strauss asked, astonished.

"Yes Ma'am." Hotch said, moving forward. He explained the entire situation from finding the unsub's identity, to the scene where Emily and Reid had been injected, to everything that had taken place at the hospital. "They will inform us the minute they know anything...in the meantime..."

"Your team is off rotation." Strauss said firmly.

"Ma'am..." Emily began to protest. She still had the ability to make 'ma'am' sound just as much like a curse word as she had as an adult. JJ quickly moved forward and clamped her hand over her friend's mouth before she had the chance to say anything further that would come back to bite her in the ass once she was back to normal.

"You're down two team members, there are other teams who can take the cases until we've got this all sorted out. Keep it under wraps, god knows we do not want the media getting a hold on this."

"Yes ma'am."

"I...can they do paperwork?"

"We're right here ma'am." Emily said with a glare as she shoved JJ's hand away. "And we're not deaf."

"Right, keep them out of the bullpen. They can finish their paperwork, then I want them out of sight, all of you...two weeks vacation. Hopefully you won't need that long." Strauss gave one final look to Emily and Reid, shook her head and walked out.

"Alright!" Morgan cheered. "Vacation."

"After you finish your paperwork." Hotch reminded him.

Garcia turned to Emily and Reid, a wicked grin on her face. "You two are coming shopping with me!" She cheered. Reid instantly looked panicked and Emily looked ready to murder Garcia. "This is gonna be so much fun!"
