Elijah was lying on the couch with Horatio. He'd been awake all night but didn't want to disturb Reid. Horatio purred, gently pawing Elijah's arm.

"You're a good boy, aren't you?" Elijah hummed as he stroked Horatio.

Horatio loudly meowed, curling up beside him. Elijah kissed Horatio's head, he loved his baby.

"Morning." Reid yawned as he walked downstairs.

"Good morning, darling. Sleep well?" Elijah looked over at him.

"Yeah, must've needed it." Reid hummed,"Did you?"

"Of course." Elijah nodded.

"Elijah."

"What?"

"Truth."

"I've.. Been down here with Horatio since probably.. Around one?" Elijah admitted.

Reid sighed,"You should've woken me up."

"I didn't want to." Elijah sighed,"You needed sleep and I didn't want to disturb you."

"You need sleep too."

"I'm fine."

Reid sighed and sat down beside his fiancé, hugging him.

Elijah curled up in Reid's arms,".. I'm sorry."

"For what?"

"Now I've made you worried about me."

"I'm always worried about you." Reid chuckled.

"You shouldn't be." Elijah sighed.

"I have every right to be. You're going to be my husband."

Elijah looked down, holding onto Reid tightly.

"And I can't wait for the day." Reid smiled.

"Still, I shouldn't make you worry like this. It's not fair on you."

"It's all apart of life." He hummed.

Elijah looked up at Reid, gently kissing his cheek. Horatio leaned up, nudging the boys.

"Yes, I love you too Horatio." Reid nodded.

"He stayed with me all night." Elijah sighed softly.

"He's a good kitty."

"I love him."

"He loves you too."

Elijah smiled softly, closing his eyes.

*********************************

"Do you think we'll ever get married?" Fleur asked Derek while she got ready.

"Of course we will." Morgan hummed.

"When?"

"Well, I don't know.. Someday."

"We can work up to it." Fleur chuckled.

"Of course we can." Morgan smiled, wrapping his arms around her.

"One day soon, right?" Fleur looked up at him.

"Definitely." Morgan kissed her cheek.

Fleur smiled,"Pass me my shirt, would you?"

Morgan reached behind him and grabbed it,"This one?"

"What would be better, pink or green?" Fleur wondered.

"I think you look good in both.. But I think green."

"Green it is." Fleur hummed.

"Have I ever told you how beautiful you are?" Morgan asked.

"Maybe.. A couple times." Fleur chuckled.

"Well, I don't think I've told you enough." Morgan hummed.

"I do like it." Fleur nodded.

"You look great." Morgan told her.

"Thank you, Mr Morgan." Fleur bowed.

"Not a problem, chérie."

"We better be going, Hotch called us for a reason." Fleur turned to him.

"I suppose you're right." Morgan sighed,"I really should stop planning things."

"One day we'll have a night out." Fleur assured him.

"If we're lucky." Morgan chuckled.

"Maybe a few hours." She hummed.

"If only."

"Come on, slow poke." Fleur tapped his arm.

"I'll show you slow poke." Morgan smirked

"Derek Morgan, mind out of the gutter." Fleur laughed, petting Beau.

"Sorry." Morgan chuckled,"We'll see you when we get back, buddy."

Beau barked, looking up at them.

"And yes, I'll take you out on a w-a-l-k."

Beau jumped up on the bed, spinning around.

"Smart pup." Fleur laughed.

"Now you be a good boy." Morgan pointed.

Beau panted, sitting down on the bed.

*********************************

"His name's William Hightower." JJ pointed to the image on the screen as they sat on the Conference Room,"He claims over the past month, he's picked ten people off the streets of Detroit, killed them and dumped their bodies across the border in Canada."

"Has he given up the dump site?" Emily asked.

"He said he'll only talk to the FBI." JJ shook her head.

"Do we have confirmation these people are even missing?" Reid tilted his head.

"Two were reported missing by family months ago, but they all appear to be transients. Were having a hard time finding any information on them." JJ explained.

"Garcia." Hotch turned to her.

"Like a bloodhound, sir." Garcia walked out.

"So what do we know about this guy?" Fleur asked.

"Until two months ago, he was a sergeant in the U.S army. He did two tours in Iraq. He lost his left leg in a roadside ambush." Hotch told them,"He was discharged with a Purple Heart and a commendation for valor."

"And the Royal Canadian Mounted Police are requesting our help?" Reid blinked.

"They don't have a lot of choice." Elijah sighed.

"He manages to get away with ten murders, why crash the guard post?" Fleur shook her head.

"It could be an attempted suicide and maybe he was trying to take as many people with him as he could." Emily suggested.

"It may also be a cause of post traumatic stress disorder." Rossi mentioned.

"I don't know." Hotch crossed his arms.

"Do we think he's legit?" Morgan raised a brow.

"I think its too many bodies to take chances." Hotch answered.

*********************************

"He documented them all in detail. Names, photos, dates and locations where he took them." JJ looked through the pictures of the victims.

"Military background, he's bound to be organised." Morgan nodded.

"He definitely doesn't have a type." Rossi shook his head.

"The only consistency is that they were all abducted from the same area." Reid crossed his arms.

"Yeah, what do we know about that?" Emily asked.

"It's called the Cass Corridor, it's right here." Reid pointed to a map,"It has a high concentration of drug trafficking, prostitution and homeless people."

"All high risk behaviour." Rossi sighed.

"So, for this guy, maybe it's more about opportunity than victimology?" Emily suggested.

"Morgan, Deans and Prentiss, when we land, I want you to head straight to Detroit. See if you hear anything in the whisper stream. I want to make sure we have a crime before we get too deeply into this." Hotch ordered.

"I hear Detroit is beautiful in the spring." Elijah hummed.

"The rest of us will meet with the legal attaché before we head to the Royal Canadian Mounted Police." Hotch nodded.

"Actually, sir, the officer in charge said that his team was part of a fellowship the BAU gave to train police forces in profiling." JJ told him.

"That was the first one we ever did. Jeff Bedwell." Rossi nodded.

"You know him?"

"Yeah." He hummed.

"He any good?" Morgan raised a brow.

"He better be. I trained him."

*********************************

Hotch and Fleur then walked into the interview room with William, he'd been staring at them through the glass for a while.

"I'm Aaron Hotchner. I'm the Behavioral Analysis Unit Chief with the FBI." Hotch introduced himself,"This is my colleague, Supervisory Special Agent Fleur Howards."

"You're here to analyse me." William looked ahead.

"No. I'm here to take your confession and find out where you dumped your victims." Hotch crossed his arms,"Or are you wasting my time?"

"I gave you names. I gave you dates."

"But you didn't give us a dump site." Fleur tilted her head.

Hotch sat down in front of William,"You were a Sargent. You lead troops. You probably lost men."

"A few." William answered.

"How would their parents feel if they didn't know whether or not their sons were dead or alive?" Hotch questioned.

"Don't lecture me on notifying families. I've been on those doorsteps. No one cares about those people. Why should I?" William asked.

"See, that's just the thing, William. We talked to the people on the street. You were out there every night, you took their photographs, you checked off their names in a notebook." Hotch pointed.

"So?"

"Your behaviour was more like a protector, like someone in the army doing a bed check." Fleur nodded,"You've gone through a lot of trouble to confess to a crime you didn't commit."

"The folks on the street, did they tell you people were missing?" William asked.

"If my team is here, there are cases we are not working on. You're wasting our time." Hotch leaned forward.

"Ten people dead, huh? That's not enough for you?"

"I've watched the tape of you at the border cross over and over again. You wait until every gaurd is out of the booth before you crash into it. If you wanted to kill people, you had your chance." Hotch shook his head.

"Are you investigating these murders or not?!" William shouted.

"So that's what this is all about? Making sure we investigate?" Hotch raised a brow,"If you though people were being killed, you should've gone to the police in Detroit."

"I did. Three times." William nodded, his voice breaking slightly,"They told me the kind of people I was looking for disappeared. They said that's the way life on the street works. So you believe the people I showed you are missing?"

"I believe it's possible."

"Don't give me a political answer!"

"Tell me what happened the night before the border cross." Fleur spoke.

"I did a head count. Every night for the past month, like we did in Baghdad. That night, I saw saw a boy named Charles wasn't where he usually camped down, so I made another pass." William told her.

"He didn't turn up?" Fleur tilted her head.

"By the morning, I knew he was gone."

"William, people don't do what you did out of honor. They do it out of love. Who were you looking for on the streets every night?"

"I got home from Iraq.. First thing my mother told me was that my baby sister, Lee, was out of the streets. She asked me to find her." William explained.

"But you couldn't?" Fleur tilted her head.

"Managed once. Brought her home and got her fed. She even wore my dog tags, for good luck." William was holding back tears,"Two weeks later, she slipped back onto the streets. That was it."

"William, you've got so much information about the other potential victims. Why not Lee?" Hotch asked.

"I hid it in the spare tyre of my car. I needed to wait until I was sure that you were on board." William admitted.

*********************************

Elijah, Morgan and Emily were talking to a cop near the alleyway they searched.

"William Hightower? Yeah, I remember him. He was sincere. I felt for him." The girl sighed.

"But you didn't look into it?" Morgan asked.

"Families don't want to see what we do. They'd rather believe she was dead than admit she's turning tricks in Chicago or Toronto."

"We believe William Hightower might be right. You might have a serial killer." Elijah told her, crossing his arms,"We want you to open up your records. Let our analyst take a look at reports from the past few months and see if there's been a change in the crime pattern, disturbances or assaults that may be connected."

"I can do that." She nodded.

"We'd also like to give your colleagues the working profile once we have it to see if anything sparks." Elijah added.

"Fair enough. So how did he convince the FBI to look I to this?" The Detective asked.

"He drove his car into the guard post at the Port Huron border and then confessed to murdering ten people." Emily informed her.

"Seriously?"

"Yes." Morgan nodded.

"How many victims did you say?" She turned to Morgan.

"Potentially eleven, including his sister."

*********************************

"We believe the man we are looking for is a sexual sadist." Rossi began.

"What this means is that for him, torture becomes a substitute for the sex act." Reid explained.

"The fact he's stealing medical equipment like sterilising agents and anesthesia tells us he may be performing experiments or surgeries on his victims." Fleur sighed.

"We believe this Unsub gets gratification from his ability to keep his victims alive in order to endure more torture." Elijah told them.

"The choice of stolen items is extremely specific, which makes us believe he's got a medical background." Hotch added.

"Check disciplinary files at hospitals, med schools and community health organizations. People would have noticed his behaviour." Morgan contiued.

"This is someone who would volunteer to preform painful procedures and he would spend extra time probing, say, a broken hand or a distended abdomen." Emily nodded.

"And after a long day, when everyone else is emotionally drained from multiple traumas and mangled bodies, he'd be the one pushing his co-workers to go out for a drink and talk about their day." Elijah sighed.

"And we know what you're thinking. A profile is fine, but, yes, our best shot at stopping this guy is still to catch him in the act." Emily stated.

"This Unsub is extremely smart and obviously organized. He's managed to abduct very different victims with very different abilities, all with no witnesses." Reid explained.

"Now, we're coordinating with the police and our agents on the ground in Detroit." Hotch sighed.

"We've also asked Sargent Hightower to act as a guide on the streets in Detroit while he's in our custody." Rossi added.

"That's it. Any questions, you find me or one of the agents." The lead detecive nodded.

The officers began leaving the room. William turned in his seat, going to leave before he saw JJ walk into the station with his mother.

"Why is she here?" William pointed.

"We've notified all the family members we can locate." Hotch told him.

"But my mother?"

"It's her daughter." Rossi nodded.

"I can't see her." William shook his head.

"You might just have to."

*********************************

"This group is going to stick close to Cass Avenue. These here are usually on the corners. They don't stray." William told Elijah, Morgan and Benning as they sat in the SUV.

"It's like I said the first time I was out here, it is not easy for someone to be isolated. Everything is out in the open." Morgan sighed.

"Okay, that's Walter Patterson. He showed me the lay of the land." William got out the SUV, calling Walter over.

Elijah and Morgan looked between each other before they got out as well.

"This is Detective Benning and Agents Morgan and Deans. They need your smarts." William explained.

"You know he lost his baby sister, right?" Walter hummed.

"Yes, we do." Elijah nodded.

"Spread the word, they're not here to hassle anyone. Be safe." William sighed.

"So.. What do you want to know?" Walter asked as William walked off.

"What would make you separate from everyone else out here?" Benning asked.

"These days, nothing."

"Theres gotta be something." Elijah shook his head,"You go to the bathroom, grab some food, drugs, women?"

"Everybody's extra careful right now." Walter shook his head.

"But people gotta have secrets, even on the streets Walter." Morgan told him.

"The only thing I keep secret out here is money." Walter nodded.

"Listen, when someone out here is on welfare, where do they go to get their cheque?" Morgan asked.

"Depends what they want." Walter shrugged.

"What do you mean?" Benning tilted her head.

"Those cheques have strings. You've got to either spend it on food or lodging." Walter began,"A lot of people out here don't want food or lodging."

"This is one of those money secrets you were taking about?" Elijah raised a brow.

"There's a motel on third." Walter sighed.

"So, you walk away with drug money but you're still on the street." Morgan nodded slowly.

"Dope fiends keep it quiet. They don't want anyone to know they're holding that much cash." Walter explained.

"Explains why they're alone." Benning looked over at them.

"And they'd be looking to score. If they thought somebody was a dealer, they'd walk right up to them." Morgan sighed,"Walter, thank you."

"Thank you." Elijah nodded to Walter as they headed back to their SUV.

*********************************

The team were at the Canadain borders, waiting for the UnSub.

"He should have tried to make the cross at least an hour ago." Reid sighed.

"Any word from the off-road sites?" Rossi asked.

"I have agents at every known drug smuggling entry. Nothing." Bedwell shook his head.

"This Unsub's smart. Everything about his plan is well-researched. I think his border crossings would be consistent." Hotch told them.

"Are there former shipping lanes?" Fleur wondered, looking at the map,"Something he could have studied in advance?'

"Nothing marked." Emily shook her head.

"Hunters might know the terrain, but it's word of mouth. Nothing documented." Bedwell shrugged.

"What about the Underground Railroad?" William looked around.

"How so?" Rossi tilted his head.

"Well, in the Civil War, Detroit was the last stop for slaves before they escaped to freedom in Canada. They made the crossing in this area." William explained.

"He's right, but there aren't any historical landmarks that register the crossing points." Bedwell shook his head.

"Well, if I remember right, they built a series of Victorian homes along the river to signify safe passage. Some of those homes might still exist." Morgan informed him.

"We know your sister's cell phone registered at a tower near Port Huron. He had to be close by when he crossed the border." Rossi tilted his head.

"Garcia." Hotch took out his phone.

"Present." Garcia hummed.

"Is it possible to cross-reference Civil War maps with Victorian homes that still exist in the Port Huron area?" He asked.

"Well, I'm going to take that question as rhetorical. And I've got one. Three miles south of a Blue Water Bridge." Garcia typed.

"Can you send me a GPS map?"

"Coming now." Garcia nodded.

"Thanks." Hotch hung up,"Prentiss, you and William come with me. The rest of you stay here. We might need to be mobile in a hurry."

*********************************

Everyone had travelled to the address Garcia sent, guns out and vests on as they entered the house. It was dark inside and quiet, far too quiet. As they entered another room however, they saw a man laid in bed, connected to various machines that seemed to be keeping him alive.

"Sir, are you alright?" Hotch asked.

"Who the hell are you?" The man looked up at them.

"Did someone do this to you?"

"Get the hell out of my house."

"You're Mason Turner?" Fleur blinked.

"That's not your business." Mason answered.

Elijah looked between the others and Mason,"He's our Unsub?"
