A/N: So since I was off of work today I had so much time for myself and was just on a writing binger. And I wrote this chapter after writing the last chapter this morning and then I also wrote ANOTHER chapter after this one. I was going to try and get you guys to review more in order to get an update but I just thought I would be nice and spoil you and give you two chapters in one day! BUTTTTTTT I'm going to keep the next chapter to myself and wait until I get some reviews until I post the next one! Days off are nice, getting to write chapters in advance is a nice thing. I have another one Saturday so who knows maybe something good like this can happen again… anyways. Here's the next chapter, please review and thank you to those who already have and the favorites and such! I'm loving writing this so I hope you love reading it. Especially the fluff, I'm such romantic.

I'm gonna paint you by numbers, and color you in. And if things go right, we can frame it and put it on a wall ~Ed Sheeran

Caitlyn fumbled a little with the key before entering her room, flipping on the light switch to show a monotone set up. A small desk with one chair, a bed and an assortment of boxes with the bare minimums that she would need. When the incident commander told her she would be going to Quantico he didn't tell her how long, so she grabbed what she needed… maybe a little more seeing that she was a girl and females always had a tendency to overpack. Locking her gun in the safe that was provided in the room, she then proceeded to get ready for bed. After taking a shower she sat alone on the hotel bed, no TV on, no radio, a big t-shirt hanging on her frame. It wasn't until then that she realized that she was smiling and hadn't stopped since she got off of the bus. She had a feeling in her stomach that was unsettling… butterflies? It wasn't like she had never been interested in anyone before or gone on dates. But this was different. She's heard plenty of songs about falling for someone in such a short amount of time, and she's seen in the movie the connection that happened instantly and was like fireworks. These were things that she thought were commercial frauds for lonely and hopeless romantics. The couples stories tell and end with "and the rest was history." Or the gaze from across the room, the unexplainable attraction.

It was happening to her. Caitlyn felt like a 15 year old giddy with happiness because the quarterback asked her on a date. With how hard and long she had to work, she had never really been in love, that over whelming, think about you every second of the day love. She heard stories from friends that said they were in love with someone that they only spent a week or a few days with and never found that love again. I guess there is no formula like Spencer had said. She wasn't in love with Spencer, she had just met him and had known him for about a week and a half, but here she was sitting alone in a motel room smiling like an idiot. All she could think about was the way he got so excited and rambled and even when she was bored she didn't want to tell him to stop. The way he smoothed the locks of his brown hair behind his ears. Spencer definitely wasn't her usual type, but there was something unexplainable about the attraction she felt to him. She was somewhat afraid, which was one of the reasons a lot of the times that she didn't get into relationships, the commitment, all of it that made her bail and back off and try and find something wrong so she could distance herself. She looked at the clock, 12:04. Still a little buzzed from her beer she reached over for her phone.

"Hello?"

"Hey, did I wake you up?"

"Oh no, I have bad insomnia I was just reading." Spencer replied, "Everything okay?"

"Yeah, yeah. I was just sitting here and couldn't sleep and…" Why was she calling him? She really couldn't wait to see him until the morning?

"What are you reading?" The young doctor obviously didn't mind because the two talked on the phone until Caitlyn inevitably fell asleep with him on the other line.

Caitlyn looked up at the large menu at the coffee shop,

"Hmmm…" she hummed as she read, Spencer looked over at her, the way her brow furrowed as she read over menus as if she was making a life or death decision when it was really just a cup of coffee. "Do you know what you want?"

"Yes, I'll take a red eye, please." he said to the Barista.

"And I'll take a triple shot of expresso over ice with some milk, please. Oh! And a bagel." Caitlyn ordered, she turned around quickly as she saw the young doctor reach for his wallet and put her hand on his wrist.

"Did you forget I was on the swat team, I know combat, doctor." Reid blushed at the contact and how close her face was to his when she said that.

"Okay, okay." He surrendered as Caitlyn paid for their coffees.

"You drink three shots of expresso? That's your coffee?" Reid asked.

"Yes, asks the man drinking a red eye." she joked, putting cream cheese on her bagel and offering him the other half which he accepted. It was as if the Thai restaurant changed everything. It went from this timid fragile thing between the two of them, and now they were laughing and sharing bagels.

"So… I know we're around a lot of profilers. I think they're going to notice us… if there is an us." Caitlyn started.

"Is there an us?" Reid asked.

"I think there's the beginning of a possibility of an us." she smiled.

"I think as long as we do our jobs and keep it professional in the office there will be no problems. But they're all going to ask-"

"I know what to say, you on the other hand just start spitting statistics or something." Caitlyn winked at him.

Both of the agents exited the elevators coffee's in hand and went to their separate cubicles. Taking a chance here and there to take glances at one another. Morgan was at Reid's desk before he knew it.

"Thai food and coffee in the morning? She slept over? Reid you sly dog!" Instantly the young doctor got extremely nervous and started speaking in his normal quick nervous pace.

"We just went out to dinner and then talked on the phone all night and went to coffee, if you could just please not do this I don't even know what it is-"

"Slow down, slow down. I promise I won't pry. But that's good Reid. Have you ever felt like this about anyone before?"

"Never. It's weird, I've been trying to find any kind of official term on it and I'm trying to figure out why someone like her is spending her time on me."

"Stop that right now, you know better than anyone else that the human mind works differently for anyone else and no matter what happened to you growing up, you are just as good as the rest of us. A little annoying but just as good." Morgan assured him and Reid just pushed his lips together in a line and nodded.

"There's a new agent in Hotch's office. What is this bring a stranger to work day?" Penelope asked, coming to the middle of all the cubicles and talking to all the agents.

"So I won't be the new one, rad." Caitlyn said.

"Okay, you just said rad. I like you." Penelope confirmed, resulting in a laugh from Caitlyn. Penelope looked from her to Reid and then back to Caitlyn wanting to bombard them with questions and squeal over the cuteness that she so ever desired on a daily basis and ask her what the young genius was like out of the office.

"We have a case." Hotch said, heading to the conference room all the agents getting to follow him, a young brunette following the unit chief as Caitlyn had done weeks before.

"Everyone this is SSA Emily Prentiss. Take a seat." The young woman took a seat next to Caitlyn who leaned over and whispered to her. Caitlyn saw her holding her things and could tell her entrance to the team wasn't welcomed and her body language proved it as she sat down, she seemed uncomfortable. Maybe Caitlyn was a better profiler than she thought.

"Don't worry, I'm brand new too and you're probably way more qualified than me so… we can be buddies. I'm Caitlyn."

"Alright. I'm Emily."

J.J assumed her position at the front of a series of boards with evidence posted to it.

"St. Louis is in trouble, they have two serial killers on their hands." All of the agents went to take a closer took at the board.

"This killer takes them from public places and dumps them in the woods, we consulted on this months ago after the third murder." Gideon told the team.

"And now it might be up to six." J.J informed, telling about the latest victim.

"No wonder it takes days to find the body the forest is 1.8 million acres and 78 thousand of that is wilderness." Reid stated looking at a map. J.J filled on the victimology as Caitlyn looked over the crime scene photos. The unsub sent a letter signing it as the hollowman.

"So we have two un subs that are trying to out do one another?" Caitlyn asked.

"Sounds like sibling rivalry to me." Morgan said.

"Let's go." Emily was to stay at headquarters, Caitlyn was unsure why and bid her goodbye and told her she would see her when she got back.

After grabbing their go bags and arriving on the plane, JJ passed out manilla folders with the information that they needed in it. They all sat in silence, Spencer's brow was furrowed, his hands curled over his mouth, thumb swaying back and forth wildly.

"What's up?" Caitlyn asked, noticing his deep thought.

"You know there are roughly 30 serial killers in the US at any given time, it's incredibly rare occurrence to have them operating in the same city."

"How many times has that happened?" JJ asked.

"To my knowledge, 3 times," he began, and then continued to explain those instances.

All of the agents started to go over their facts, Caitlyn was always amazed at the way that they worked off of one another and she felt privileged to be able to engage with these great minds. Reid was assigned to look over the letter for psycholinguistics, while Gideon and Morgan went to talk to the families. Caitlyn went along with JJ to talk to the reporter and some of the police staff. They directed the reporter to not talk about the hollow man in order to draw the shooter out. He was communicating with the reporter. News of a missing woman's body was found and Caitlyn was looking another dead body in the eyes. Caitlyn leaned down and used a swab on her lips.

"This lipstick is fresh… and if she was dumped here her hair wouldn't look like this. She's been groomed."

"This isn't about remorse, this is about revisiting the victims."

"Like Ted Bundy, sexual acts with their deceased victims." Caitlyn shuddered.

"Now we know he has a ritual and we'll be here waiting for him."

Yet another shooting, Caitlyn this time was with Reid and Hotch. Gideon wanted her looking at as many crime scenes as possible to understand how to connect it with the personality profiles that they used to create their profiles.
"You alright with all this?" Reid whispered in her ear.

"Two serial killers on a battle to beat one another, no." She answered looking at the scene.

"No, I mean all the dead bodies, you haven't flinched."

"You don't have to worry about me Spence, ever. I'm good I'm just trying to learn." She smiled softly at him.
"Alright what do you two see." Hotch asked.

"Two victims at once, thats a first for him." Reid started.

"He chose a different hunting ground," Caitlyn started, "yeah we're in an alley but it's behind an expensive hotel."

"He displayed the newspaper between them." Reid said.

"It's deliberating. He wants us to know he's angry." Hotch answered.

"Angry enough to change his M.O.?" Caitlyn asked.

"Exactly." Hotch confirmed walking away.

"And you said you weren't a profiler." Reid smiled at her, Caitlyn returned the smile and followed their unit chief back to their car.

Caitlyn poured herself another cup of coffee, before going back to look over the crime scene photos. It had been days and she had stayed awake for long periods of time before but this is something she was definitely going to have to get used to.

"You doing okay, little shot?" Morgan asked, making a word play on her age and the previous nickname he had given her.

"Yeah, I can do this. Just some getting used to is all. And I want to catch this son of a bitch."

Reid then came into the room after looking over the writing of the notes of the shooter, informing the team what he had found and began to deliver the profile. The young doctor explained the that the un sub has a job in solitude that may strip him of his identity.

"Or he could be too over qualified and feel that its demeaning him… right?" Caitlyn asked, always nervous to give her opinion and second guessing herself. The young doctor smiled,

"Right." They weren't doing the best job of keeping their connection a secret, atleast not to Gideon and Morgan and anyone else who suspected it. They informed the differences between the two killers, saying how the shooter will be harder to find because he doesn't have any close contact with his victims. While the other is ritualistic and may be charming and handsome to get his victims in his grasps.

Another woman was missing. She fit his type, and had the mil-creek killers M.O. screaming from it. Gideon told them that they had to find the body and wait for him to come back to fit his ritual.

"Sex with a corpse," Caitlyn shuddered, whispering to Spencer as they tried to look over the maps, "now that is getting to me."

Morgan was spitting off his ideas as he thought about the dump sites, finding out that they may not be random. Garcia came to the rescue when they narrowed down the fact that he may be someone who works as a ranger. Caitlyn and the others waited at the station while Gideon and Morgan went to go find the body. Only to have that plan fail because the hollow man intercepted.

"This is just turning into a huge game. Our plan was ruined because of the hollow man?" Caitlyn asked.

"He's alerted the media and injected himself into the investigation." Morgan said of the reporter in regards to the headline, 'Hollowman helps the FBI find victim.'

"He's getting the attention he's been craving." JJ said with an eye roll.

"If he really wanted to get this guy caught he would have called us and not have alerted the media." Morgan said, Caitlyn looked over at Reid watching as he thought, swearing she could see his brain working. Another almost victim was called in and confirmed the man was handsome and was able to give the agents a sketch. Hitch and Reid both stayed looking over at victimology. Caitlyn called Hotch to give him an update.

"You're doing really well, Robertson." Hotch complimented, Caitlyn smiled as she hung up the phone and they headed back to the station.

The three agents were welcomed back by Reid finding the missing piece of the puzzle. Both the killers had been talking for months in the classified ads in the newspapers using code names. Reid grabbed a clicker and began to explain what led him to his discovery, Caitlyn forced herself to focus on the material and not the agent presenting it.

"They're using the names Sunny and Holden… like from Catcher and the Rye?" Caitlyn asked.

"It's a beloved book of psychopaths." Hotch answered "they relate to holden's isolation."

"I read that in highschool…" Caitlyn said to herself under her breath, "sick."

"We understand their relationship, let's use it against them." Hotch smirked for the first time Caitlyn had ever seen him get even close to a smile. The team formulated a plan to do a fake classified AD, with Reid copying the linguistic patterns. Caitlyn looked over his shoulder as he worked.

"Hey, Cait." Reid whispered very quietly, "do you mind if you um… go help Morgan. I'm not easily distracted but you're very close to me and I can smell your perfume…it's um…"

"Say no more, sorry." She said going with Gideon and Morgan to place the fake 'gift' gift of a victim to the hollowman. Taking the bait, the man arrived and Caitlyn held her breath as she waited to see if he was going to follow though with his signature, she second he pulled out the lipstick she botled from the bushes.

"FBI! Dont move!" She yelled pointing her gun at him.

One down, one to go. A press conference set the bait and caught the second killer. Caitlyn sat down to Reid on the plane, both exchanging a smile and a knowing glance as Reid went back to reading his book and Caitlyn listened to her music, leaning her arm close to his to have the most subtle amount of contact as possible. When they finally reached the BAU Prentiss was still there.

"Hi Emily," Caitlyn said "tell me you haven't been here for the past 4 days."

"How did the case go?" She asked.

"Prentiss." Hotch called the young brunette into her office.

"I have to go. Wish me luck." she said turning around.

Caitlyn placed her files on the desk, and looked around for Reid.

"Who are you looking for?" Garcia asked.

"What, I'm not looking for anybody." Caitlyn answered, the young doctor coming up behind her.

"Ready to go?" he asked. Caitlyn looked at Garcia,

"I meant Reid. We carpooled he lives close by where I'm staying." she lied, "see you tomorrow!"

"This might be a little harder than we thought." Caitlyn whispered to him, as they walked into the elevator.

"You know what, I don't even care" The doctor smiled at her.

"You don't?"

"Well as long as we get our work done and don't endanger anyone or blur each other's judgement they can think what they want."

"Wow, alright then." Caitlyn smiled.

"Should we go get something to eat? Or there's a Korean film festival that we can go to, I mean there aren't subtitles but I can translate for you."
"Yeah, I guess." Caitlyn shrugged, his eyes lighting up at her response. She honestly just wanted to go for some sake and to hear him whisper translations in her ear.

"So freaking cute." Penelope whispered to herself as the elevator door closed.
