This story takes place at the end of season 15, where Amanda makes the assumption that Olivia and Trevor had history. That got me thinking what if they did? How will Amanda, Amaro, and Barba react to the news about it and the fact that Fin knew about it. The beginning is straight from the show the direct quotes are in Italic writing, and then it veers off to my take on what happens if Amanda's assumptions were right. Throughout the story there will be flashbacks to help tie everything together and I apologized in advanced for jumping from scene to scene.

Olivia and Murphy were both gather together around Fin and Rollins desks as they discuss the latest case regarding little Tino and Ellie when Trevor Langan walked into the squad room.

"I'm looking for Ellie Porter," Langan says as he walks over to the group. "Sorry I'm late but I just caught the case."

Olivia glances over at Trevor, it has been years since she seen him and spoken to him. Seeing him now brings back old memories that she tried to forget, pushing those memories to the back of her mind Olivia takes a deep breath and averts her eyes from his and decides to concentrate on his tie instead. "I thought she had a public defender." Olivia says quickly before turning towards Rollins. "Rollins, meet Trevor Langan, he's a, uh, high-priced mouthpiece for lowlifes." Olivia says as she turns back to Langan with a slight smirk on her face.

Trevor tilts his head slightly as he looks at Olivia before saying, "And you, once," Trevor retorts back, "how soon we forget. It's nice to see you, detective," Trevor adds.

"It's actually Sergeant now," Olivia says correcting him. "So what, you caught a pro bono?" Olivia asks as she looks up at him, her thoughts running a mile a minute, trying to remain calm and collected in front of him, not wanting to let him see that his presence at the moment was affecting her.

Trevor nods as he looks into her eyes, old memories start to flood his mind also and he tries to shake them away, keeping his mind focus on why he's there but it's not easy when he looks at her, seeing how beautiful she is. "Yeah, do a few of them a year. It keeps me an honest lawyer." Trevor responds.

"An oxymoron," Murphy interjects.

Olivia kicks herself for not introducing her new C.O. to him, "Uh, this is our new C.O., Lieutenant Murphy."

"Wow. A lot of changes around here," Trevor says as he takes a quick glance around the squad room.

Olivia nods in agreement, "Yeah," she responds as she avoids his eyes.

Looking at her he starts to think about what she has been through over the past year. "Uh, and you, are you doing okay, with, uh…uh, everything?" Trevor stumbles over his words, not knowing how to approach the subject, not wanting to make the situation even more uncomfortable for her.

Olivia gives him a small smile, "Yeah, I'm fine. Thanks." Olivia says genuinely touched by his concerned, then again why wouldn't he. Olivia moves towards her desk as Trevor walks away to go see his client.

Amanda leans back in her chair to look over at Olivia, "he's tall," she says simply but it has so much more meaning behind it.

Olivia gives a quick laugh, "Yeah, like that's a skill set." Olivia says knowing exactly what she was hinting at as she continues towards her desk.

Amanda narrows her eyes at the Sergeant sensing something between the defense attorney and her colleague. "You two have history?" Amanda questions.

"I don't date lawyers." Olivia lies with another laugh as she sits down at her desk not wanting to discuss her relationships with the detective, plus honestly it wasn't any of her business.

Amanda leans back up in her chair as she slightly tilts her head at the Sergeant knowing she was lying. "Since when?" Amanda retorts letting the Sergeant know that she caught her in a lie.

Olivia doesn't respond to the question, in fact she ignores the detectives eyes and the comment as she starts to work on her computer.

*****SVU*****

After their victim identifies Ellie as the woman he hired and set him up Olivia and Trevor steps to the side to talk. Amanda watches Langan and Olivia talk, their body language and how close he stands to her just adds to her assumption that they had history together, her curiosity gets the best of her and she knows she can question her partner about it later. Amanda turns her attention back to their victim who needs to identify Tino as his attacker.

Later on, when Olivia is in the interrogation room with Langan and Ellie Porter, Amanda sits at her desk across from her partner, Fin, and stares at him wondering if he would know if Langan and Olivia ever had history.

Fin glances up from the file that is on his desk as he feels his partner burning a hole in his head. He looks at Amanda as he leans back in his chair, "What's going through your mind?" Fin asked having a clue though, his partner has been eyeing Langan and Olivia ever since he got here.

Amanda stands up and walks over to sit on Fin's desk, "What do you know about Olivia and Langan. I know she says 'she doesn't date lawyers'" Amanda says putting air quotations on the last statement making Fin laugh. "But come on, we all know she dated Haden when he was our ADA, so I know she lied, and I have a gut feeling that she's lying about Langan." Amanda says.

Fin just shakes his head, not wanting to betray his friends trust, "Manda if she did or didn't it's not really our business, you don't see her all in your love life do you?" Fin says wanting this conversation to be over with already.

Sighing slightly Amanda could understand where he partner was coming from, yet her curiosity was winning out. Deciding that she'll drop the subject for now and do some side investigating own her own she stands up and head back over to her desk to try and concentrate on her paperwork for now. Making a mental note that in a day or two she will start to investigate the relationship between her Sergeant and Langan.

Olivia and Trevor exists the interrogation room after trying yet failing to convince Ellie Porter to turn on her pimp Little Tino.

Trevor reaches over and gently grabs Olivia's elbow stopping her in her tracts. Glancing around as to make sure they were alone he turns his attention back to Olivia. "Liv," Langan breathes as he gathers his thoughts. "I miss you." Trevor finally says looking into Olivia's eyes, trying to convey all his emotions to her.

Olivia quickly averts her eyes seeing all the emotions that flashed through Trevor's eyes. "Trevor," Olivia breathes as she tries to pull from his grasps. "I…can't, not now." Olivia says as she tries to gain control of her emotions but she was losing the battle, she needed to get away from him before the battle is completely lost.

Trevor nods as he lets go of her elbow. "Can we do coffee or lunch then, please, you owe me that much," Trevor begs.

Olivia closes her eyes as she runs her hand through her hair. "Fine, but let's do dinner instead, have plans with the ladies for lunch." Olivia says quickly.

Trevor let's a smile spread across his face. "Okay, sounds good, I'll text you the time and place." Trevor says as his phone rings, "I'll see you later." Trevor says walking away answering his phone.

***SVU***

Later that evening Olivia arrives at the little Italian restaurant where she was to meet Trevor for dinner. As she went to pull the door open she wondered if this was a good idea, yet she knew that Trevor was right, she owed it to him. Taking a deep breath she walked into the restaurant and glances around looking for Trevor and quickly finds him at a table in the corner near the back.

Trevor looks up as he watched Olivia make her way towards him, a small smile makes its way onto his face as he remembers back to August 28, 2001.

Flashback:

Trevor stood at the end of the aisle as he waited for her to walk through the door and make her way towards him. He has never been so nervous in his life yet excited and thrilled at the same time. The moment finally came when the doors to the church opened and there she was looking more beautiful than ever. He watched as the person she looked up to as a father walked her down the aisle towards him. The moment came when they approached him and he was handed the hand of his beautiful wife-to-be in less than a half hour.

End of flashback

"Trevor," Olivia says softly as she sets her hand on his shoulder.

Shaking his head a little he gave her a small smile, "Sorry, thanks for coming." Trevor says as he watched Olivia take a seat in front of him.

"What were you thinking about?" Olivia asked as she picked up the menu in front of her.

"Our wedding day," Trevor replies with a smile on his face as he took a sip of his wine.

Fin walks into the squad room where he finds Amanda, Barba and to his surprise Nick and Munch. "Munch my man long time, no see." Fin says as he embraces his old friend, "What brings you by?" Fin asks

"Well since this one," Munch says pointing at Nick, "Decided to get himself thrown into jail I thought I'll bail him out, again." Munch says glancing over at Nick.

Fin nods in understanding, "Yeah, maybe you can talk some sense into him while you're here." Fin says as he sits on top of his desk. "Hey how about we head over to my place and have some beer and pizza." Fin offers to the little group.

"Shouldn't you check with Casey first?" Munch asked looking over at Fin with questioning eyes.

"Who's Casey?" Barba asked looking around the group of detectives. He's not one to keep up with their personal lives unless he had too.

"Casey is his girlfriend that he moved in with, about six months ago. You should know her, she's an ADA." Amanda answered in response to Barba's question.

"Yeah, her last name is Novak she works for the Homicide unit." Munch added.

"She used to be the ADA for us right?" Nick asked, trying to connect the dots.

Fin nodded, "Yes, she's use be our ADA, now that we got that cleared up, do you guys want to go and have beer and pizza at my place. I'm sure Casey will be ok with it, in fact she might even join us." Fin said almost in a rush, not wanting to delve into his personal life with anyone at the moment.

Everyone agreed to head over to Fin's place to hang out and eat. As they headed out of the squad room, Fin texted Olivia to see if she wanted to join them before texting Casey to let her know that the squad was coming over for beer and pizza.

After picking up the pizza and beer they arrived at Fin's apartment. "Babe," Fin yelled as he walked into the apartment with the pizza and everyone else following behind him. "Shoes off guys, Casey's rule," Fin explained as he got a raised eyebrow from Amanda. Fin walked into their living room to find his girlfriend sitting on the floor surrounded with DVD's. "Babe what are you doing?" Fin asked as he set the pizza down on the coffee table.

Casey looked up from her spot, "Oh hey, sorry I was just looking through some of these DVD's that contains pictures on them." Casey explained as she took out a DVD from the DVD player and put another one in. Casey walked over to Fin giving him a quick kiss, "Some of them are unlabeled and I have no idea which DVD contains what pictures, etc. So I am going through them all and then labeling." Casey explained further when she saw the confused look on his face. "I was bored and I've wanted to do this for a while so that we can finally put that electronic picture display or whatever it's called to good use." Casey said receiving a nod from Fin. Casey turned towards the group behind him. "Hey guys," Casey said with a smile.

"Uh, Casey this is Barba our ADA, Barba this is Casey, I'm sure you two have probably meet in passing at the courthouse." Fin says as he introduced them.

Casey nods, "Yeah, Barba, we ran into each other a couple of times." Casey says receiving a nod from Barba.

"And I'm sure you remember Nick and Amanda and that old man over there." Fin said with a small chuckle at Munch faking hurt.

"Yup, you guys make yourself at home, please excuse my mess on the floor over there just a little project I'm working on." Casey explains before turning back to Fin. "I'll be right back need to grab something from the bedroom. Is Liv coming also?"

Fin shook his head, "No she said she had a meeting with someone, or something like that."

Casey nods, "Oh yeah I forgot she told me that when we met for lunch this afternoon. I'll call her later to see how it went." Casey said jotting her head towards their room, letting Fin know to follow her.

"Be right back guys, make yourself comfortable." Fin said following Casey.

Everyone made their way over to the coach and loveseat and did just as Fin said they made themselves comfortable. Nick, Barba and Munch took their suit jackets off and loosen their ties as they sat down. Nick looked over at Amanda when he heard her gasps. "What's wrong with you?" Nick asked seeing her eyes grow wide.

"I knew it…I knew it. I had this feeling that Liv and Langan had history but she denied it say 'she didn't date lawyers', but I knew she was lying. I can't believe it." Amanda said still in disbelief.

Nick raised an eyebrow at her, "Wait, what." Nick said clearly still confused.

Amanda pointed to the pictures that were appearing on the flat screen in front of them. "Those are wedding pictures of Olivia and Langan, a defense attorney that we met today who's representing someone we just arrested for conspiracy of attempted murder and robbery." Amanda turned towards Munch, "Those two used to be married?" Amanda asked.

Munched looked around the room at the three set of eyes that were staring at him. Knowing there was no way around it simply said, "Yeah, they were married, for almost ten years."
