~MR. SCRATCH (Season 10, Episode 21)~

~Criminal Minds~

Jacey stirred in her sleep, whimpering softly. Being half asleep, but could hear Jacey's whimpers, Spencer instinctively turned over to wrap his arms around her.

Feeling at peace, Jacey's dream went from night terrors to instant tranquil.

Suddenly, the vibration from two different phones on two different nightstands filled the ears of the new parents.

Groaning, waking up from their slumber, the pair answered their phones at the same time.

"Dr. Montgomery," Jacey sleepily mumbled the same time Spencer said his name.

"Jacey, we've stumbled upon a case and the BAU needs your assistant." The voice of Aaron Hotchner said in her ear. Jacey attempted to blink the sleep out of her eyes.

"We'll be there soon." Reid and Jacey said in unison before hanging up their phones. The pair turned around to look at each other, both giving the other a knowing look.

"What time is it?" Jacey asked.

"9:47 p.m." Spencer answered as he got up from his position on the bed. The sound of the thunderstorm woke Jacey up out of her tiredness.

The mother sighed before shaking her head, "And it's storming."

"I'll call Mandy." Spencer said, grabbing his clothes and phone.

"I'll go check on Mia." Jacey said, putting her robe over shoulders.

~Criminal Minds~

Jacey walked into the nursery. As soon as she did, she could hear her daughter's coos. Smiling to herself, Jacey walked over to the crib. Big blue eyes stared at the mother.

Mia had her hand in her mouth, sucking on it as she kicked her feet. When she made eye contact with her mom, her coos seem to have gotten louder.

"The storms keeping you up, huh?" Jacey asked the infant. Mia started to spit bubbles as she waved her arms around while kicking her feet. "Oh, my little Minnow." Jacey picked up her baby, and head her close to her chest. "I love you."

Spencer walked in, hanging up his cellphone. "Jace?"

Jacey turned around, Mia still in her arms. "Yeah?"

"Mandy's not answering and we need to leave soon. So...what do you want to do?"

Jacey swayed back in forth, bouncing Mia in her arms. "Well, I can always have her in my office while we work. If she could sleep then she wouldn't really be too much to handle."

"Are you sure?" Spencer asked softly. "I don't want you stressing out."

"Yes, love, I'm sure." Jacey said, gently pressing her forehead against Mia's. She looked at Spencer and smiled. "You want to get her things ready while I change?"

Spencer nodded, taking his little girl from her mother's grasp, grinning at the baby. "You're not gonna give me a hard time, right, Mia?"

Mia grinned at her dad, showing all four of her teeth.

~Criminal Minds~

Jacey has been in her office since last night, going over her notes and theories. "Three people. Three different lives. Same story."

Jacey held her head in her hands. Not understanding what's truly happening. She then heard whimpering from her daughter, who was waking up in her portable play pen. Not recognizing her usual setting, Mia began to cry.

Jacey rushed over to the baby, coddling close, trying to protect the child from her own tears. "Mommy's here. It's okay. We're just in my office, Mia." The baby looked around before looking at her mother again. "You hungry? Mandy should be here soon to pick you up."

The seven month old baby was starting to get the hang off solid food since she has a total of four teeth, two on the bottom and two on the top. But in moments where Jacey needs to get back to work, she'll let Mia settle for a bottle.

The mother walked over to the baby bouncer, that she set up last night, and placed Mia in it. Once on her feet, the baby started bouncing while playing with her toys the surrounded her in the bouncer. Jacey set a small bottle in front of her, as well as some animal crackers she could chew on until it's dissolved. Mia was content, so Jacey went back to work.

~Criminal Minds~

"Every drug effects every person differently, yet somehow this unsub is able to make his drug affect 3 dissimilar people in the same way." Spencer said, going over the newest case with the team.

"Maybe they're not dissimilar at all." Jacey said, making her way into the conference room, taking her seat next to Spencer.

"Maybe the drugs are just the tipping point, and these 3 share the same pre-existing mental condition he knows he can tap into to induce them to kill. We find that. We find him." Aaron said, agreeing with Jacey to some sense.

"I'll go see if I can get a hold to any medical records, regarding their psyche. Maybe there's a similarity in the therapist or topics they've each discussed about." Jacey said as she got up from her seat.

"We'll interview the victims and send you or findings." Aaron told her. Jacey nodded as she walked away. "And Jacey..." The doctor turned around, Aaron catching her attention. "Thank you."

She gave the agent a small smile, "You're welcome. Don't mention it. We're saving lives after all."

~Criminal Minds~

On the other side of the room, behind the two-sided window, Jacey watched Aaron Hotchner and David Rossi give Christine, one of the victims, an interview. Introducing the smell of safe to get her out of the trance she's in.

"That's not true," the woman said, tearing up at the thought of "home". Christine, the woman, thought she was four again.

Her face was frozen, she started to lightly scratch her face. "He's coming." She continued to scratch her face, her expression becoming frighten. "He's-He's coming!"

"Who's coming?" Aaron asked calmly.

"He's on the other side of the door."

"Christine." Aaron said, trying to get her to calm down.

The lights began to flicker. "He's coming. He's coming. He's coming. He's coming." Jacey stood there, unsure on what to do or what to say. The whole scene becoming too eerie for her liking. "He's coming!"

An idea of what was going on instantly crossed her mind, she ran to the front of the BAU floor. Garcia rushing out from her office yelling, "Unplug! Unplug everything!"

Jacey shook her head, "Shit." She ran back to the interrogation center to see Christine still freaking out.

"He's coming," she screamed, scratching her face harder as she continued to have a breakdown.

Jacey rushed in the room to stand between Aaron and Rossi. "Christine, stop," the therapist said in a calm but stern tone.

"AAH!" Christine screamed as the lights blew out of place, the sparks fanning across the room. Jacey grabbed her father's hand, freaked out about what was going on. "He's coming! He's coming!"

It was completely dark, but Jacey could still hear her scream. David quickly pulled out his phone and turned on the flashlight, recording the rest of the session. Jacey kneeled beside the woman, along with Aaron, who was trying to her get her to stop scratching herself.

"Christine. Christine, stop," Jacey tried to say soothly. "Who's coming?"

"Who's coming?" Aaron asked.

"Christine, you have to stop."

"I can't. I can't. He's coming. He's coming." She yelled, sobbing at her words.

"Who is coming? Who is coming?" Aaron continued to ask Christine, keeping her hands from her face.

"Mr. Scratch," she said, completely scared out of her mind.

Jacey looked at both her dad and Aaron. Christine stared at the therapist. "He's already here."

~Criminal Minds~

Jacey lit the last candle in her office. She was officially spooked. Whatever or whoever this unsub was, he was a damn near genius. It felt like he was five steps ahead of them. Knocking them out before their best lead could say much.

Jacey sighed, rubbing her hands against her neck. "That fucking mastermind. That fucking genius. How the fuck–?"

That's when it dawned on her. No one could ever pull this off, not unless you had the mind to work with NASA or any other top notched place.

"Son of a bitch," Jacey whispered to herself before leaving her office to find the others.

~Criminal Minds~

"Encryption's a highly specialized skill set, but it's fundamentally a mathematical process, which means it's a human process, so sometimes your technique can reveal where you learned it." Spencer stated, gathering the pattern in which the encryptions where in. "I think I know where he learned how to do this."

"Where?" Kate asked.

"Harvard." Jacey stated, making her way into the room to stand beside Spencer. "It took me a minute to even think about this but once I heard Spencer talk about the encryptions, everything started to really make sense." She leaned beside Spencer, to get a look at the patterns of the handy work done by the unsub. "It's damn near perfect."

"Has to be if he can hack in the FBI database." Penelope mumbled.

"Harvard," Jacey repeated, shaking her head.

"Which is oddly enough, since the school is not known for its advanced math program, but it is known for one particular class." Spencer continued for Jacey.

"When you're good at math, good enough to get into Harvard, you take a math class called Math 15." Jacey started to explain to the group of agents.

"When you're better than that, you take Math 25, but when you're the best. The absolute best, you take math 55--" Spencer explained with the therapist.

"Honors Advanced Calculus and Linear Algebra." Jacey said, folding her arms under her chest. "Graduates are immediately employed by the U.S. Government--"

"Because they're too dangerous to work anywhere else. More specifically, they're employed by the NSA."

"Oh, sir, that would make a lot of sense." Garcia said, taking note of the information that was said. Aaron's facial expression was more gravely than normal, he pulled out his phone and stalked off, mentioning that someone he knew had twenty minutes to meet him.

~Criminal Minds~

"We might be home late tonight," Jacey mentioned to her babysitter, who's been at home with her daughter all day. "Don't worry, I'll pay you extra, for sure. I hate that you're always cooped up at my place. Listen, for future reference, if you want to get out of the house, let me know where you're going and if it's appropriate to take a baby...you can. I just need to check some things out before you can though."

Jacey laughed at Mandy's response. "I need to get back to work so I can get home. Read Mia to sleep tonight, thank you."

"You okay?" Spencer asked from his spot at the doorway.

Jacey nearly jumped at the sound of his voice, but almost immediately recognizing who it was, she was okay. "I'm still a little spooked, but...I'm okay. Or at least, I'll try to be."

"This case will definitely be one we'll remember."

Jacey scoffed humorlessly. "Yeah, don't think I'll be forgetting this for a while."

There was a pause between the two before Jacey sighed. "You should have seen what kind of mind state Christine was in. I know you've seen the video but...it's nothing like seeing it first hand. How could someone do that? How could someone just sabotage another's life?"

"Maybe that's what the unsub said about the victims when they were kids," Spencer stated, making his way to stand beside Jacey.

Jacey nodded, seeing his point. "I know. I just– I can't attempt to paint this unsub as a victim though. I know his life was ruined but dammit...this is just too much."

Spencer placed his hand on her waist, pulling her into an embrace. She laid her head on his shoulder, taking in the smell of his cologne. Spencer pressed his lips against her forehead as he traced small circles into her side.

"How's Mia? I overheard you on the phone with Mandy."

"Mia's fine. She's fussy, but that's because she's still teething. I told Mandy to just rub that teething medicine on her gums so it won't hurt as much."

"Reid!" Derek called out. The couple jumped, releasing each other from their embrace. "Hotch is taking too long, he might need back up, let's go."

Spencer started to walk off before Jacey grabbed his hand. "Be careful."

The emotion she allowed to linger in those two words let Spencer know that she felt this man, the unsub, was dangerous and she wasn't comfortable with her father and lover out there near him.

Spencer lifted her hand to his lips, kissing her brown knuckles before whispering, "Always."

Jacey watched him leave, closing her eyes, praying to whoever was listening. Praying that the people she cared about would stay safe.

~Criminal Minds~

Reading through her paperwork in her bed, Jacey sighed. Spencer walked out of the bathroom, cleaned up and in his pajamas. He instantly noticed the paperwork on the bed, he glanced at his girlfriend.

"You've been working all day. I think it's safe to say the we have the rest of the night off. Just-- take a break." Spencer pleaded. He knew his lady was a workaholic but he's never seen her so invested in a case.

"I just want to finish up my side of the paperwork so this asshat, Peter Lewis, can fry quicker." Jacey mumbled, she was fuming. "He hurt Hotch. When you guys came back from the crime scene, I immediately pulled Hotchner in my office. Seeing him so disoriented and dazed, watching him relive that traumatic moment made me feel so bad. And guilty. I should of went after that guy, he wouldn't have gotten into my head."

"He would have. He'd use the people you care about most against you. He's smart. And he always has a plan."

"Yeah? Well, there's no planning in prison. I'm going to make sure he has no contacts in there."

Spencer watched the woman in front of him, he admire her passion and drive for things to be brought to justice. But he didn't want to watch her go through another sleepless night. "Jace."

She looked up to see her man's pleading eyes, Jacey could tell he was tired and wanted to have a relaxing night. Knowing that she was being a tad bit much, she sighed, gathering her work and putting it in her bag.

"You win." Jacey commented as she threw her bag by their bedroom door. "Come cuddle me."

Spencer's lips twitches upward as he climbed into bed, embracing the woman that laid next to him.

And in that moment, things felt right. Things felt safe.

THANK YOU GUYS FOR THE SUPPORT AND LOVE YOU SHOW THIS BOOK! It means so much to me.

I'd love to see some more feedback! If you have any questions, ask and I'll reply in the next chapter!

Holy shit! Can you believe that Mia is seven months old already?! She's growing up way too fast on us. I've calculated her age with the help of Kate's (Jennifer Love Hewitt) pregnancy! During the Mr. Scratch episode she was hitting seven months pregnant. Mia was nearly a month old when Kate got pregnant. Keep in mind, Kate didn't tell the group she was pregnant until she was like three months along.

Anyways, thank you again! I'll see you in the next chapter!
