A/N: A little scare last chapter, but it's all ok! Let's go away with Chapter 52!

Whatif-ifonly: You have no idea where I'm going with this, do you? Trust me, you'll be very surprised.

JJ rifled through one of the bags of shopping, trying to find the green apples. In the bottom of the bag, her hand brushed up against what felt like an apple. Pulling it out of the bag, she looked up, and laughed at what she saw. Spencer was walking into the lounge room, Nathaniel fidgeting in his arms, and Olivia wrapped around his leg, so she was completely off the floor, and Toby trotting behind him, his teeth hooked onto the hem of Spencer's pants.

"Livy, what are you doing?" JJ laughed. Olivia giggled. Spencer stopped, and looked down at his ride along.

"Mommy, I tied!" Olivia explained.

"You're tired? So you got Daddy to carry you?" JJ asked. Olivia nodded, giggling. JJ had to laugh at her daughter's reasoning. Walking over, she prised Olivia's arms from around Spencer's leg, and lifted her up.

"Toby! No!" she scolded. Toby let go of Spencer's pants, and sat down, flashing his puppy eyes at JJ. Her heart melted.

"You are just too cute, Tobester," she said, bending down and ruffling his head. Toby was satisfied, and trotted off to find something to chew.

"Mommy," Olivia whined softly.

"What is it baby?" JJ asked, pushing her daughter's hair away from her eyes.

"I sick," Olivia told her.

"You don't feel well?" JJ asked, a little concerned. Olivia shook her head, her thin blonde hair bouncing around. JJ bent down and pressed her lips to Olivia's forehead, seeing how warm her temperature was.

"You're a little warm, baby girl. Want some medicine?" she asked.

"Yucky"

"I know, but it'll make you feel better," JJ explained. As she stood up to get the Tylenol, Olivia fell backwards, her eyes closing as she began shaking violently. JJ turned around out of habit, and yelled out.

"Spence!" she screamed, moving quickly over to Olivia. Nathaniel put his head up from his blanket to see what the commotion was. Toby came running as well, skidding across the floorboards and slamming into the coffee table. JJ held Olivia's head still, so she wouldn't hit it against the armrest of the couch, tears streaming down her face. Spencer came sprinting into the room.

"JJ, wh...jesus, what happened!" he yelled.

"I don't know, Spence, call 911! Hurry!" JJ sobbed, cradling Olivia's head in her hands. Nathaniel began to cry in a very distressed way, which only made JJ more frantic.

"I know baby boy, I know, it's alright," she cried desperately. Spencer ran back into the room, the phone at his ear, and lifted Nathaniel off the floor, silently trying to soothe him while he waited for the operator to connect the call.

"911, where are you calling from?" the 911 operator answered. Spencer hastily gave her the address.

"What service do you require?"

"Medical, please hurry!"

"Ok, sir, you need to remain calm. What seems to be the problem?"

"My two year old daughter's having a seizure," Spencer said, his voice rising helplessly. JJ was almost in hysterics by now.

"Alright, you need to hold her head firmly, so that she doesn't induce a head trauma"

"My wife is already doing that"

"Another important thing that needs to be done is that you need to put something between her teeth, to prevent her from biting her tongue," the operator explained. Spencer searched frantically around the room, his eyes coming to rest on the thick plastic drumstick from Olivia and Nathaniel's toy drums. Picking it up, he tossed it to JJ, who read his mind, and put it between Olivia's teeth.

"Ok, sir, how bad is the seizure? On a scale of 1 to 10, with 1 being quite mild," the operator asked.

"About a 7 or an 8," Spencer managed to say. In his mind, all he could think was that he had to stay calm if he was going to help Olivia.

"That's pretty violent for a two year old. The ambulance should be nearly there, they've been dispatched from a local station," the operator told him.

"Yes-I...I can hear the sirens," Spencer replied. Sure enough, they were getting louder with every passing minute.

"Sir, keep me on the phone until the paramedics arrive"

By the time the paramedics pulled up, Olivia had been seizing non-stop for nearly 10 minutes. Spencer thanked the operator as he let the men inside, and hung up, dropping the phone on the couch. Toby leapt out of the way, diving behind his beanbag to hide from the strangers.

"How long has she been seizing?" the first medic asked.

"Nearly ten minutes," Spencer relayed.

"Ok, Miss, we need you to step away. It's alright, we're here to help," the second medic coaxed gently. Spencer took JJ's hand and pulled her away, reluctantly on her part, from Olivia. She buried her face in his chest, sobbing uncontrollably.

Five minutes later...

Spencer watched as the medics wheeled Olivia out on a gurney, an oxygen mask on her tiny face, an IV drip in her arm. JJ went with her, clutching the little girl's hand tightly, making sure she knew she was there. Spencer grabbed his phone, wallet, keys, and Nathaniel's jacket, and carried the baby boy out to the car. Quickly, he buckled Nathaniel into his car seat, got into the driver's seat, and followed the ambulance to the hospital.

JJ and Spencer stood in the trauma room, looking at their little girl. She had been given medication to stop the seizure, and was now stable, but still unconscious. Dr Kipney came over to them, holding a clipboard.

"Does Olivia have a history of seizures or epilepsy?" she asked gently. JJ shook her head, her arms folded across her chest, unable to tear her eyes away from her two year old. Spencer put his arm around her, holding her tightly.

"Did she have an accident in the past 24 hours that may have contributed to this?" Kipney asked.

"The only thing that was unusual was that she had a high fever!" JJ exclaimed in frustration.

"Mrs Jareau, it's alright. I'm only trying to help," Kipney replied.

"I-I'm sorry, I just...I need some air," JJ muttered, before turning and leaving the room, heading for the entrance into the ambulance bay.

"I'm really sorry about this, I'll be right back," Spencer said hastily.

"It's ok, Dr Reid. I'll be right here with Olivia when you get back," Kipney said gently. Spencer nodded, and turned to follow JJ's path.

Spencer found JJ sitting on the step outside, across from the ER entrance. Walking over to her, he saw no tears, just a sullen expression.

"Jen, baby, what's wrong, apart from the obvious?" he asked as he sat down beside her.

"I'm worried sick about Livy, and I just feel extremely miserable. Where's Nathaniel?" she replied.

"Chelsea came down while you were with Livy. She's on the Paediatric floor, entertaining him in the playroom. Surely you can't blame the majority of your attitude on hormones?" Spencer teased gently. JJ cracked a tiny smile.

"Trust me, I can. Wait until I get into a full blown rage," she shot back. Spencer smiled, and stood up, holding out his hand for JJ. She allowed him to pull her up, and lead her back inside.

"Call me ignorant, but how far along are you?" Spencer asked as they walked across the bay. JJ whacked him lightly in the back of the head.

"12 weeks," she replied. Spencer nodded contentedly. They remained in silence until they got back to the trauma room. Dr Kipney was checking the IV bag, while another doctor was checking Olivia's eyes and lungs.

"Ah, you're back. Dr Luka, this is Jennifer Jareau-Reid and Dr Spencer Reid, Olivia's parents," Kipney said, introducing them to the new doctor.

"Medicine?" Luka asked as he shook Spencer's hand.

"PhD's," Spencer replied.

"Of course...ok, we got consent from you earlier for a spinal tap, which we conducted. It has ruled out meningitis, which is very lucky," Luka explained. JJ and Spencer nodded. Luka bent down, and was about to double check Olivia's pupils when he froze.

"What the-?" he muttered, turning off his torch. Gently, he brushed Olivia's hair away from her forehead, and closely inspected her hairline.

"What is it?" Kipney and JJ asked in unison.

"Jason, can you go get the Symptoms journal from the lounge?" Luka said to the nurse. Jason nodded, and ran down the hallway to the doctor's lounge. Within minutes, he was back, holding a journal that was so big, with writing so small, even Spencer would take a while to read it. Luka grabbed it, and flipped through it frantically, stopping in the M section.

"Oh my god," he muttered, checking Olivia's hairline again.

"What is it?" JJ repeated.

"Olivia has measles," Luka said frantically. The nurses instantly ran for the cabinets, searching for the appropriate medications.

"Has Olivia had her vaccinations?" Kipney asked hastily. JJ thought for a moment, before groaning.

"Shit!" she exclaimed.

"What?" everyone in the room cried out, making her jump.

"She's supposed to get the booster shot tomorrow morning!" JJ exclaimed.

"Jason, call the PICU isolation unit, we're bringing up a two year old with measles! Mrs Jareau, do you have other children? Because if you do, they will have been exposed to the virus, and they will need to be checked," Luka explained, as Kipney put an isolation mask on Olivia. JJ felt tears well in her eyes.

"We have a seven month old boy...and I'm pregnant," she choked. Luka led the two to an exam room while Kipney and Jason took Olivia upstairs.

"I need to check your son, and you need to be checked out as well. Are your vaccinations up to date?" he asked.

"I'm not sure," JJ said softly.

"Mrs Jareau, if your baby has been exposed to the virus, there could be some complications," Luka explained. JJ felt like she was going to cry, and within a few minutes, the tears had broken through.

"I'll-I'll find out," she stammered.

A/N: Ok, I had to cut it there, or we would have had a 3,000 word chapter easily. I hope you liked it!

I've lost my voice!

Please leave lengthy reviews where possible! Reviews make my voice come back!
