"You'd make a cute couple," Emily said to her friend and they watched the New Orleans detective leave the station.

"No…We wouldn't," JJ said as she walked away in the opposite direction.

…

"I'm pregnant," JJ said. Emily was the first person she had shared her unexpected news with.

"What? How?" Emily asked surprised.

"Ah…the normal way," JJ answered not really knowing what Emily was trying to ask.

"No, I mean, who's the father?"

"A guy I was dating. But we broke up before I found out."

"Are you going to tell him?" Emily asked.

"I don't know."

…

6 years later

…

"Jennifer Jareau?" She said answering the call.

"Hi, it's William LaMontagne. I don't know if you remember me but-," She didn't even need to hear his name, his southern drawl was hard to forget.

"Will. Of course I remember you."

"That's good I guess."

"Why are you calling?" She asked. They hadn't spoken since Miami six years ago.

"Are you still with the FBI?"

"I am."

"The BAU?"

"Yes. Why?"

"Well a couple of years back I transferred to the MPD, got a promotion, you know but that doesn't matter. We got these cases. A half dozen or so. And I believe they're connected. But another detective doesn't. And I don't want to call the BAU in if it's not a BAU case. So I was wondering if you and your team could look at them, but without letting anyone know you're looking into it."

"Ah sure, I guess. Just send through the files and-"

"That's the problem. I only have access to half the files."

"Will, we can't properly analyse the case if we don't have all the files."

"Well what about your tech girl, if she's still there of course, but couldn't she be able to get into our database unnoticed or something?"

"We don't hack into other agencies."

"It was just a thought. But I don't know what to do. This guy won't give me access to his reports and I can't not do anything."

"Look, I can talk to Hotch, and maybe he'll be okay with what you've got."

"Thanks JJ."

"I'll call you back after I've talked to him," JJ said hanging up the call. She didn't move for a while. She couldn't believe who she had just spoken to. She looked at the framed photo of Henry on her desk, and hoped the fact that she hadn't informed Will about the pregnancy wouldn't harm their son.

…

"Hotch," JJ said knocking on her boss' door, not waiting for an answer, she walked in.

"We have a case?" He asked upon seeing the media liaison in his office.

"Uh maybe. Do you remember Detective LaMontagne?" JJ asked but Hotch's face said 'who?' "He worked two cases with us. One in New Orleans in 2007 and then in Miami a year later."

"Ah yes. Why?" he asked once he remembered the detective.

"He lives in D.C. now, and he's got a case he believes is serial, but the other detectives don't. So he's only got access to half the files because of it, and he wants us to look into it, but to keep it on the down low," JJ explained.

Hotch went silent, thinking it over. "Without all the files its makes it harder but we've worked with less. But from what I remember he was a good detective, so tell him to bring what he has to the Bureau and we'll take a look for him."

"You want him to come here?" JJ asked. She wasn't sure if she was ready for that.

"That's what I just said."

"Today? Tomorrow? Next week?"

"We don't have a case right now. So today would work."

"Today," she repeated. She would have to come to terms with seeing Will faster than she thought.

"JJ, is everything alright?"

"What? Yeah, why wouldn't it be? It'll be good to see him again," she lied, though she didn't think she was all that convincing. "I'll go call him now."

…

JJ sat back at her desk. When the day started she had no idea this was how it was going to go. She never imagined hearing from Will again, not after this long. And she never thought she would be seeing him. She thought about him far more often than she ever would care to admit. Henry had favoured to look more like her, but she could see a little bit of Will every once in a while.

She hoped she wouldn't have to see much of him while he was here because she didn't know if she would be able to keep Henry a secret.

"Yeah?" JJ said as she answered her cell phone. She had saved Will's number after their last call.

"Hey, I'm here. But they say I need a visitors pass to go up, and I need someone to verify the visitors pass."

"Okay, just give me a minute," JJ said hanging up, and then called Anderson to go down and get him.

…

"Detective LaMontagne?" Anderson called out when he got to the foyer.

"Yeah, that's me," Will said walking over to the man who had just called his name. He was sure JJ said she'd come and get him, but maybe he heard her wrong.

"I'm Agent Anderson, I'll take you up to the BAU offices."

"Nice to meet you," Will said holding out his hand as they walked to the elevator.

…

"JJ," Anderson knocked on her office door and was surprised to see her standing at a filing cabinet close by. "Detective LaMontagne."

"Thanks Grant," she said as Will walked in. This was the first time they had seen each other since they parted ways in Miami six years ago.

They waited until Anderson had left before either of them spoke.

"It's good seeing you, JJ," Will said as they stepped in for a hug. She thought they probably lingered for a little too long for a regular hug, but neither of them seemed to want to pull away.

"It's good to see you too," JJ said as they pulled away from the embrace.

"So this is your office," Will said as he started to walk around the room. When they were dating he had always wondered what the room she had called a second home looked like, now he couldn't believe he was seeing it and seeing her.

"How about I give you a tour of the BAU and reintroduce you to everyone," JJ suggested frantically, as she step to block Will from getting behind her desk, she didn't want Will seeing the picture of Henry and herself.

They walked together silently until they reached the glass doors. "So this is the bullpen, it's basically the profilers' office. There's a kitchen over there," she said pointing off to the distance. "And Hotch's, Rossi's, and Morgan's offices are this way," she continued as they walked in that direction.

Upon reaching Hotch's office she opened the door and let themselves enter without knocking. "Hotch. Detective LaMontagne."

"It's good to see you again," Will said walking to the desk and holding out his hand which Hotch took.

"Yes, you too. Please take a seat," he motioned.

"I'll wait outside," JJ said and she closed the door behind her.

"JJ, was that William LaMontagne?" Emily asked, coming up to the rails and looking up to her friend.

"You have a good memory," JJ said surprised.

"Well, you know me, always remember the hot ones," she joked and JJ laughed somewhat awkwardly. No one knew that Will was Henry's father. "What's he doing here?"

"Needs help with a case."

"Well obviously, I meant here, in the BAU."

"It's a long story."

"JJ," Will said as he opened the door to Hotch's office. "Can you come back in here?"

"Sure," JJ said as she tapped on the rail, kind of a goodbye to Emily. "So?" she asked after walking back in.

"I have to go back into the precinct," Will said. "But I have the day off tomorrow, so I'll be coming back in for the day."

"So tomorrow we'll have the team working through these cases, and I'll get you and Will working on the cases we don't have. I think I remember you two worked well together," Hotch said, and JJ smiled and pretended that what he just said didn't send her mind and stomach spinning.

"Sounds like a plan," Will said. "But I best be getting back."

"I'll walk you out," JJ offered. They walked silently until they were out of the bullpen and heading to the elevator. "Did you tell him about us?"

"What? No," he answered as she pushed the elevator button.

"Well, what did you say?"

"We talked about the case, then my phone rang saying I was needed back at the station, then we called you back in. You were out of the room for a minute," he explained as the elevator opened up. "See you tomorrow," he waved as he got in.

"Will", JJ, called as the doors started to close.

"Yeah?" He asked holding the door open

"Can you please just keep the fact that we had a relationship quiet?"

"Just like old times," he said as the doors began to close again.
