Author's Note: I had this idea when I re-watchedthe whole four seasons, and I always had the impression that the reason as to why Sam was unable to commit was due to a past relationship that he wasn't truly over. I hope you enjoy!

Chapter One

Downtown Toronto - 15 Division

The atmosphere within 15 Division was tense. The day that the station had been dreading for the most part of a month was looming over them. The impending undercover stint, devised by Luke Callaghan, was dangerous enough without the added pressure and anxiety of bringing a new rookie along. It had been planned that Sam Swarek and his rookie Andy McNally would go undercover to try and capture a notorious drug dealer who had started selling drugs to children. It was a long haul, but Sam was good at his job and with his professionalism, it was to be a short affair. With every undercover operation, there were dangers at every angle and Sam was ready for them. His rookie, however, seemed to be struggling.

"You sure you're ready to do this?"

Andy glanced towards Sam and nodded, before continuing to get ready. Sam narrowed his eyes at her and bit his lip. He was good at reading people; it was something that he had spent many years doing, and one of the reasons why he loved his job. He could read Andy like a book, and he knew, just by looking at the expression on her face, the glint in her eye, or observing her nervously rubbing her neck, how and what she was thinking and feeling. He knew more about her than she actually knew about herself.

"You know... you can tell me if you want to do this or not?" Sam continued, to which Andy froze.

"I do... I mean... I'm just a little nervous," Andy replied, her voice small. "That's all."

"I always get nervous. Even now... and I've been doing this for ten years. It's normal, Andy," Sam whispered, stepping towards her and pulling her towards him. She held him tightly, as if clinging on for dear life. He tenderly placed a kiss on top of her head, taking in the delicate aromas of her shampoo. "I'm going to be with you, okay? I'm not going to let anyone hurt you. Got that?"

"Yeah..." Andy whispered, nodding against his chest. "I know that."

Sam placed one last kiss upon her head before moving towards his bag. They had less than ten minutes before they had to travel towards the warehouse, and less than ten minutes to truly prepare themselves for the unknown that was waiting for them. The case was a difficult one; but like all officers, the more difficult the case was, the more rewarding and satisfying they felt afterwards. Sam had put forward McNally's name, knowing that she would do her utmost best to ensure the job was done properly and professionally. He had every faith in her, and he trusted her with his life, which was rare. Sam never trusted anyone, not for a long time, but something about McNally told him that he could put his guard down and open up to someone.

The two of them remained silent, with the occasional glance and smile, and before they knew it, the call came and they both took a deep breath. This was it... the moment they had been preparing for, for months.

"You ready?" Sam asked, to which Andy nodded. "Okay then. Let's go."

They bid their goodbyes to their colleagues, who were travelling behind them. Officers from all ranks came to wish them good luck in their quest to capture Ricky Harris. He was own to the police for his drug deals which had changed from street corner deals to major covert deals. His latest deals involved selling Class A drugs to minors, which had led to many children being hospitalised. He was a wanted man.

Toronto - Unknown Warehouse

The drive to the warehouse was short and the journey quiet, and as the vehicle came to a halt, Sam stole a glance in Andy's direction. She was biting the skin around her fingers and staring at the warehouse in front of her. Sam nudged her and she flicked her gaze towards him. He saw the fear within them.

"As soon as we step into that building, we're no longer Sam Swarek and Andy McNally, okay? We're not cops," Sam said. "You're Lizzy Evans, okay?"

Andy nodded, to which Sam continued. "I'll do the talking, yeah?"

When Andy nodded again, Sam exited the vehicle after grabbing the briefcase. Andy took a deep breath before following after him. She closed the gap between them, and slipped her hand into his when he reached for her. To Andy, the walk felt like the shortest and longest walk she would ever have to do in her life. There were only a few times in her life when she felt scared, but this time took the medal. She was petrified of the unknown, of what was going to happen and what would happen if she accidentally jeopardised the whole thing. The anticipation and anxiety overwhelmed her heart and clouded the excitement she wanted to feel.

"Ready?" Sam asked when they reached the entrance. Andy nodded. He gave a short nod and knocked on the metal door. Her hand shook in his but he gave it a quick squeeze in an attempt to reassure her. It was a few moments before they heard footsteps inside, and Sam turned to Andy.

"… and then I told him, 'well you better do something or I'll fire you!' The look on his face!" Sam laughed, turning to the man who opened the door and who filled the doorway. "Hi."

"You here for the stuff?" The man asked quietly. His arms, muscley and tattooed, were folded. His eyes darted between Sam and Andy then behind them. Once he was sure that nobody was watching them, he glanced at Sam.

Sam nodded, and stepped inside when the man moved out of the way. As Andy stepped over the threshold and into the warehouse, she felt the overwhelming feeling of running away. She took a deep breath as the man led both her and Sam upstairs.

The warehouse was run down, with paint flaking on the walls and the majority of the ceiling damp. It was once a thriving company but it was deserted a few years ago after business dropped. Since then, it had been the hot spot for many drug deals. The warehouse was known to 15 Division, though the station hadn't had problems with it for a while. Their guess was that someone was using it, and when they looked around, their hunch was confirmed. The talk on the street was that notorious drug dealers were using the warehouse as their domain, inviting people of all ages, even children, to buy drugs. They were able to get enough information out of people on the street to plan an undercover operation.

"Hey!" Ricky, the main suspect, hollered as he saw Sam. "Good to see you, bro! And your lovely girl…"

"Lizzie," Andy said, extending her hand towards the man. He shook it.

"Well, it's lovely to meet you, Lizzie. Mike has told me so much about you," Ricky said, straightening his leather jacket.

"Good things I hope," Andy laughed, glancing towards Sam.

"Of course, baby," Sam winked at her.

Ricky watched the two of them, and smiled. "You're lucky to have her, Mike. Treat her like a princess."

"I'm trying my best," Sam smirked.

"So… you still want what we spoke about? Or something a little… more?" Ricky asked, his intensive stare upon Sam. Sam thought for a moment, trying to prolong his decision. He didn't want to be too quick to answer as crooks were cautious, just like they were. They preferred a cool attitude, one that they were able to resemble themselves.

"What we spoke about," Sam replied, his voice calm.

Ricky nodded. "Good choice. Let me just get George, then we'll talk business."

Sam raised his eyebrow once Ricky turned his back. He quickly glanced towards Andy. Sam watched as Ricky left the room. The remaining man watched them, but mostly Andy. His intrusive gaze grazed over her as he took in her figure, as a cocky smirk played on his lips. Andy avoided his gaze, and kept close to Sam.

It was a few minutes before they could hear chatting between Ricky and someone else but as Sam strained his ears to listen, he was unable to decipher the owner of the second voice. The informants only ever spoke about one person who dealt with them, and that was Ricky. He glanced towards the objects around the room. There was a table on the alcove wall which had a metal briefcase on top, and hanging on the wall above the table was a map of the world. But something was wrong… he could feel the fear pierce at his heart. He had been in this job long enough to know that these types of operations weren't as smooth as to how this was transpiring. It felt… too easy.

Ricky re-entered the room, followed by a woman. She was the same height as Ricky, thanks to the size of her heels, and a tight dress clung to her body. Sam observed her, waiting for her to turn around so he could see her face, and when she did, he knew he immediately regretted it. The room began to swim, and he felt nausea overwhelm him. He tried to keep calm but he found it difficult to stop himself from shaking. His eyes met hers and he saw her falter, too.

"This is the guy who's buying from us today," Ricky said, oblivious to the exchange that was going on. "This is Mike. And his lovely lady, Lizzie."

"It's a pleasure doing business with you both today," she spoke, an unfamiliar twang to her accent. Sam narrowed his gaze at her and watched as her gaze left his and focussed on Andy. She gave the young rookie a once over before returning her gaze to Ricky.

"So, how much will it be?" Ricky asked Sam.

Sam composed himself as best he could, and said. "A few grams."

Sam moved towards the table in the middle of the room, and opened the briefcase full of money. He felt Ricky join him. Ricky tapped him on the shoulder, and nodded.

"Count the money in the other room," the woman said. "Then when it's the right amount, bring them their stuff," she glanced at Derek who was still ogling Andy. "You, too."

She watched as Ricky and Derek left the room, and waited for them to close the door. When they did, she waited another few seconds before turning her attention towards Sam and Andy. Her eyes opened wide when she looked at Sam, as if she had seen a ghost, and Andy watched in confusion as she opened her mouth a few times to speak but nothing came out. She walked towards them.

"What are you doing here, Swarek?" The woman whispered. Andy was taken aback.

"Undercover, which I'm guessing that's why you're here, too?"

The woman nodded, her hands resting on her hips. She took in a deep breath. "This was not supposed to happen. You are not supposed to be here."

"We've been tracking them for a month. This is our case. We had no idea you were here," Sam whispered. "If they find out…"

"They won't," she replied. "Just follow my lead, okay? Ricky… he isn't the type of person to just let you go. I'm sure you already knew that, Sam."

Sam nodded, and glanced towards Andy. He saw the confusion in her eyes, but he knew he didn't have enough time to tell her everything.

"They're coming back, just follow my lead…" she said, her eyes darting towards Andy who nodded. She walked quietly towards the desk, and began to rummage around to cause effect. The door opened, and Ricky and Derek entered. Ricky walked towards her, and she turned.

"The right amount," Ricky whispered. "But they want the good stuff. What shall we do now?"

"Let me handle it, okay?" she said, her eyes narrowing at Ricky. The man watched her for a moment as she tried to regain composure. She could feel the fear burn her skin as his stare bore into her. He took a step back then nodded, a sneer on his face.

"So… what were you talking about?" Ricky said, turning around. Sam went to answer but was cut off. Ricky pointed towards Andy. "Just Lizzie."

Andy faltered, her eyes glancing towards Sam who kept his gaze on Ricky. She took a deep breath and smiled. "We… uh… we were talking about our vacation. We're going to Corfu in a few weeks, and I just couldn't help mentioning it."

Ricky opened his mouth, and ran his tongue along his teeth. "Well… that's nice. Isn't it George?"

George - real name Georgia - nodded. She watched as Ricky moved towards 'Lizzie'. She had been undercover for over six months, and she knew that Ricky's behaviour was unpredictable. People trusted him, put their faith in him… and he knew that. His behaviour was irrational, with a lot of people not knowing what they were getting themselves into. She observed 'Lizzie' and could tell she was a rookie. The innocent, doe-eyed and fearful look at every situation was one that she knew herself. She had been in that same position, trying to carve a career out of the small amount of materials she had. Her eyes fell on Sam, and her heart hammered against her chest. It had been a long time since she had last seen him, and yet in the same moment, it only felt like yesterday. She always assumed that she would never see him again in her lifetime. She was wrong.

She saw the weapon in Ricky's waistband and furrowed her brow. The last time she had seen that gun - her gun - was in the drawer of the desk in the other room. She cursed herself mentally.

"Corfu is wonderful this time of year," Georgia said. "I'm sure you'll have a wonderful time."

Georgia made her way towards the windows at the back of Andy and Sam. Her heels made contact with the old wooden floorboards. She made eye contact with Sam and from the way he looked back at her, he knew that something was wrong. She went to stand by the window.

"It's such a lovely day, Ricky. Shall we just make the deal?" Georgia said, folding her arms.

Ricky stopped, his arms behind his back. He watched Georgia for a few moments, his eyes narrowed. "No," he said, his eyes going back to Sam and Andy. "I want you to get on your knees. Now."

"Why?" Sam asked, chuckling to hide the fear in his voice.

"Because I said so, got that?"

Sam and Andy fell to their knees.

"What are you doing, Ricky?" Georgia asked, tilting her head to the side. Her arms remained folded.

"I'm going to kill them."

"Why?" Georgia's voice was calm, but her body was shaking.

Ricky let out a chuckle. "Or better yet… you're going to kill them."
