It was coming to the end of a long case; the team had been investigating the murders of 5 children. None of the children had been reported missing. There was no proof that these 5 little girls even existed. This made the case hell for the team as they had no leads all week. By the time they had a suspect it was Sunday and they were all drained from a long hard case.

It was meant to be a simple arrest. Nothing in the profile suggested he wouldn't fight or run. JJ, Hotch, Emily, Derek, Rossi and Reid all pilled in to one SUV and set off to David Wheats house.

"when we get there I want Emily and Reid to take the basement, Derek and Rossi to take the ground floor and JJ and I will take the upstairs." Hotch said with authority.

A round of 'Yes sir' and nods was his reply and the rest of the journey was in silence.

Once they arrived they all got out of the SUV, guns drawn and partners by their side ready to catch this son of a bitch.

As Prentiss, Reid, Morgan and Rossi took the front door, JJ and hotch went in the back as quietly as possible.

As they creeped upstairs JJ suddenly started to feel uneasy about this arrest.

She put the thought to the back of her mind and carried on in the opposite direction to Hotch.

A round of 'clears' could be heard through the house which only made the feeling worse for JJ.

As she entered the dark room she smelt a strong smell of chemicals. She kept her gun held up ready to shoot if need be and her eyes wide open.

She heard the door creak closed behind her. She spun around gun held high but before she had the chance to shoot she felt a sharp pain in her right shoulder.

She let out an ear piercing scream as her vision started to fade away.

The last thing she saw before she blacked out was Hotch come in the unpainted old door and shoot Wheat in the head and watch him fall to the floor.

When JJ started to regain consciousness she felt dizzy and small.

She could hear voices but she couldn't make out the words being spoken.

'What the hell do we do?' She heard Emily say in a panicked tone.

'How is this even possible?' She heard Morgan speak.

'Guys, she's waking up' Hotch said softly.

JJ let out a small groan as she tried to lift her pounding head.

'What happened' JJ said weakly

Once she heard her voice she shot up instantly ignoring the pain and the dizziness.

'What's wrong with my voice.' JJ asked worriedly

When the team just started at her in silence she started to panic even more.

She put her hand to her head to try and ease away the pain but she stopped once she saw her ridiculously small hands.

'Hotch' JJ said scared as she looked at Hotch with tears in her eyes

Hotch leant down in front of JJ and wiped a few tears from her chubby cheeks that escaped her eyes.

'JJ we're gonna need to take you to the hospital straight away, okay?' Hotch said soothingly to the small girl.

As If out of habit, Hotch gently lifted JJ into his arms as he felt her wrap her small arms around his neck and bury her face into his chest sobbing.

'shhhh, you're going to be okay' Hotch said to JJ as he rubbed her back.

'Morgan, Dave and Reid you stay here and wait for CSI. Emily I need you with me at the hospital' Hotch said whilst bouncing JJ soothingly.

They all silently agreed and got on with their jobs.

Hotch handed JJ to Emily who climbed into the backseat of the SUV, holding JJ close to her

About half way to the hospital JJ stopped crying so Emily ran her thumbs across the small girl's cheeks and kissed her forehead.

'You're going to be okay I promise sweetie' Emily promised her best friend.

Once they arrived at the hospital, JJ was immediately taken away to have tests done and Hotch and Emily were both waiting impatiently for their return.

About an hour of waiting, JJ's doctor entered with little JJ clinging to his hand.

Once JJ saw hotch and Emily she ran into Hotch's arms and clung to him.

'So, I need to speak to you about my conclusions on JJ's case.' Doctor Benn asked.

'I'll go. You stay with her' Emily offered.

'There are a couple shops on the 5th floor you might be able to find some clothes for her up there.' JJ's doctor suggested.

'okay, thank you, Emily call me when you're finished here okay?' Hotch asked.

'Yeah sure.' Emily responded

After giving JJ a loving kiss on the forehead she followed the doctor into his office.

'Please take a seat' The doctor said as he motioned to one of the blue seats

'Jennifer's case is something I have never seen before so we weren't sure how to approach it. We ran some vitals on her heart and lungs and all major organs. She seems to be healthy as all the results were good. I would guess Jennifer's age at about 4 years old. Physically she is small for her age and she is also a little underweight so you need to make sure she eats 3 healthy meals a day. The thing I am worried about is her mental state. Jennifer seems very anxious and shy. She also got scared whenever a male doctor got close to her. If I were you I would try and contact her parents, ask them what she was like when she was young. Jennifer also will start acting her age. She will feel her adult self and child self-combining and this will be a very stressful and confusing situation for her so you need to be patient with her. Obviously JJ is not going to be able to stay by herself so I suggest putting her with someone she is comfortable with due to her mental state. Do you have any questions?' The doctor asks

'No thank you I'm pretty sure you covered it all. Do you think you could find a cure for this?' Emily asks worriedly.

'we are going to try, however this could take weeks, months or even years to cure.' The doctor explains sadly.

'well thank you for your time. We will make sure to call if there is any emergencies' Emily said as she shook the doctors hand and left the room running her hands over her face and sighing.

How was this happening?

Meanwhile upstairs JJ and Hotch were struggling to find an outfit for JJ.

'JJ what about this' Hotch said as he held up a brown denim skirt

JJ turned her nose up at it and hid her face in hotch's neck again.

'Guess not' Hotch thought to himself.

Just as Hotch was about to give up Emily came up behind him holding an adorable dark blue floral skirt and a pink lacy top to match. She also held a white cardigan and a pair of sparkly pink Mary-Janes.

'I figured you'd need help' Emily said smugly

Hotch grinned and handed JJ to Emily.

'Get her changed I'm going to call the guys' Hotch said

'Come on monkey' Emily said as they walked to the bathroom hand in hand.

Once JJ was changed her and Emily had done her hair in two French braids they walked out of the bathrooms to hunt down hotch.

Emily got her phone out and dialled Hotch's number

'Where the hell are you' Emily asked annoyed.

JJ was scared that Emily was going to hurt her. When Emily heard JJ whimper and grip her hand tighter she looked down to see JJ crying.

'Please don't hurt me Em'ly' JJ asked through tears.

Emily crouched down in front of JJ and pulled the hyperventilating little girl into her arms.

'JJ shhhh. Calm down baby. Try and breathe for me okay? Just breath baby.' Emily cooed.

Hotch came running up to them. He could see little JJ's chest rising and falling at a high speed and he quickly scooped her up into his arms.

'JJ sweetheart just breathe.' Hotch whispered in her ear.

'No one's going to hurt you baby.'

'You're safe I promise' Hotch continued to calm the 4-year-old down from her panic attack as best as he could.

Once JJ had calmed down she fell asleep in Hotch's arms. Hotch carried her to the car and put her in the back seat and buckled her in.

Once he and Emily were both in the car he started to drive to the airstrip to meet the rest of the team.

'It wasn't your fault' Hotch said as he looked at Emily

'She was so scared of me.' Emily asked as a single tear slipped down her face.

'I want JJ to stay with me until she's back to normal. I feel that would be the best thing for her.' Hotch said

'yeah I agree but what about Jack?' Emily asked

'Jack is at summer camp until the 7th of august, still another month. When he's back he will be glad to have someone to play with' Hotch explained

'Good idea. But me and Garcia get to buy her clothes. You've never shopped for a little girl before you are not going to stick her in a pantsuit and some sneakers' Emily said with her voice filled with humour.

'Okay fine.' Hotch said in mock defeat.

'Remember I told you she was underweight so you have got to make sure that you give her three good meals a day.' Emily double checked

'Are you forgetting I have a seven-year-old agent' Hotch said humorously

'Can you also try and figure out why she was begging me not to hurt her earlier when I didn't lay a finger on her? Something isn't right about that. What do you know about JJ's childhood?' Emily asked curiously

'Not a lot. I have left a message for Mrs Jareau like the doctor suggested. We'll see how she is in the next few days, if she gets worse than it could be worth a try on anxiety pills.' Hotch said sadly.

'Yeah let's hope it doesn't get to that' Emily sighed

They all slept the way back to DC. When they got back no one woke JJ instead Hotch lifted her gently and carried her to his car putting her in Jacks car seat. It was 3am so the roads were dead. It took them about 25 minutes to get back to hotch's. Hotch left both their bags in the car and carried her up to the guest room. He went and grabbed an old T-shirt of his and put her in it. He folded her clothes up and turned the light down a little. He left both his door and her door open just a crack.

At 5am JJ woke up not knowing where she was. She crawled out of bed and followed the light into Hotch's bedroom. He shook his arm in an attempt to wake him up.

'JJ what is it are you hurt?' Hotch asked sleepily

'I had a bad dweam' JJ responded

Hotch could see her shaking with fear and holding back tears. He grabbed her by her armpits and lifted her into his bed and held her close.

'Go back to sleep sweetheart' Hotch said whilst holding the small girl close to protect her.

They both fell back to sleep within five minutes and they didn't wake up until noon the next day. JJ and Hotch had a lot of adjusting to do.
