A/N: Thanks so much for all the awesome reviews and alerts, I read them all with joy.

Andy walked out of the station and the sight that met her made her heart sink. She saw Sam near his truck and Marlo was with him.

Andy had been working with Marlo once again. Halfway through shift Marlo had been feeling unwell. She nearly fainted. Andy sat with her to make sure that she was alright. Andy had gotten her something to eat and something to drink. While Andy insisted that Marlo went home, Marlo insisted that she had a job to do.

Throughout the whole day Marlo had been feeling weak and Andy could see it. She knew it wasn't her job to sent a superior officer home, but she was close to doing it.

What Andy saw next broke her heart, again. She saw Sam lean into Marlo, giving her a hug. After that he handed her something. When Andy saw Marlo getting in the truck her heart stopped for a moment. Sam took a step back and watched as Marlo drove away.

Sam let Marlo borrow his truck. Sam was never big on words, but he was big on actions. Andy knew that Sam letting Marlo borrow his truck meant that he was serious about her. He cared about her. He was happy with her.

All of the sudden realisation kicked in. All this time Andy was determined on fighting for Sam. She thought that if she showed him that she had grown, that he would want her back. Right now she knew that he wasn't interested anymore.

This thing with Marlo wasn't just a fling. He was serious about it.

Andy shook her head while Sam turned around. For a moment he just stood there looking at her. They were about two steps apart, but to Andy it felt like there was an ocean between them. She shook her head again and tried to get past him.

''Hey,'' Sam said. ''Marlo told me that you kept an extra eye on her today.''

''She was my partner today,'' Andy quietly said. ''I did my job.''

Sam nodded and looked at Andy. ''I trained you well.'' Sam smiled faintly. ''Always have your partners back.''

Andy shook her head again and got mad all of the sudden. ''What?'' she asked. ''You thought I wouldn't look out for my partner just because you're dating her now?''

''Andy, that's not what I,'' Sam tried.

''No Sam,'' Andy warned. ''No. You can do whatever you want. I don't care anymore.'' Andy turned around and quickly walked away from Sam.

Sam stayed frozen to his spot. He didn't really get what just happened. He really hadn't meant anything with his comment. When Marlo came into his office announcing that she was sick, he knew that she wanted him to take her home.

He was busy though, but he didn't want to be a complete ass. He knew he wasn't going to win any boyfriend of the year awards anytime soon and he felt really bad towards Marlo. So he offered her his truck and told her to take it home with her. He could always get a cab later.

When he saw Andy he wanted to talk to her. He just wanted an excuse to see her for a moment, because they had hardly worked together over the last week. He didn't know what he said that had gotten her so angry, but it proved to him once again that she was complicated.

He didn't want complicated.

He couldn't do complicated.

He needed to let Andy McNally go. That was the only option.

''God,'' Andy cursed when she sat down on a barstool at the Penny. ''I need a drink and I need it now.''

''What happened?'' Nick asked. ''What did Swarek do this time.''

Andy gave Nick a glare and squinted her eyes together. ''You know what?'' she asked. ''I don't want to talk about it. I have been wasting my time on him. He does not deserve my time anymore.''

''When did you come to that conclusion?'' Nick cautiously asked. Just a week ago Andy was determined on getting Sam back. This change of attitude was definitely surprising to say the least.

''I should have come to that conclusion ten months ago.'' Andy quickly ordered a beer when she had the barkeepers attention and turned to Nick again. ''And you know what? He said that he apologized, but he didn't. He said he made a mistake, but he did not say the words sorry or apologize.''

''Andy,'' Nick tried to interrupt.

''And his jokes, God,'' Andy groaned. ''All he ever does is make jokes when things get serious.'' Andy took a sip of the drink that Liam put in front of her. ''I am done. Over him.''

''You said you were going to fight for him just a week ago.''

Andy looked mad and shot Nick an annoyed glare. ''I was stupid a week ago.''

''Andy,'' Nick tried again. ''Let me give you a ride home, okay?''

Andy shook her head and raised her glass. ''I'm staying here. I'm having fun.''

''You don't look like you're having fun,'' Nick argued. ''Actually it looks like you're upset and I don't want you to do anything you regret later.''

''I'm not going to do anything stupid,'' Andy said a little more quietly. ''I just don't want to go home yet. I promise you that I'm going home alone tonight Nick.''

Nick sighed and put his hand on Andy's shoulder. ''I have to go,'' he said apologetic. ''Call me when you get home, okay?''

''I'll be fine Nick.''

''Just call me, please.'' Nick continued to look at Andy until she gave him a small nod. ''Take a cab. No walking home alone in the middle of the night.''

''Promise.''

A little while after Nick left, Gail walked into the Penny. She sat down next to Andy. ''So McNally, drinking your troubles away?''

''Nope,'' Andy said, popping the P.

''Looks like it.'' Gail ordered two tequilas and one beer and handed Andy one tequila when Liam got them to her. ''You know that Swarek is totally faking it with that SWAT girl, right?''

''Looks pretty happy to me.''

''Oh Andy, come on. You two are seriously the two most frustrating people I have ever met.'' Gail downed her tequila and put her glass on the bar again. ''Swarek is just trying to convince himself that he's happy.''

Andy rolled her eyes and turned to Gail. ''Since when are you an expert on feelings?'' Andy asked.

''I'm not. You guys are just super easy to read.'' Gail smiled and faced Andy. ''I know you slept with Nick,'' she said out of the blue. Andy's head snapped up and her eyes widened. ''He didn't tell me.'' Gail took a sip of her beer and turned back to Andy. ''I saw you leave together and I was working the night after, so I saw Nick's guilty face.''

''I was really, really drunk.'' Andy covered her face with her hand and shook her head. ''I would never sleep with one of your exes in a normal state of mind.''

''I did.'' Gail shrugged. ''I thought you knew that actually.''

''What?'' Andy quickly said. Her mind wondered back to eight months ago. She left Sam behind, but Nick left Gail behind too. The thought of Sam and Gail finding comfort in each other's arms was sickening. Even though she had no right to feel that way.

''God can you be more transparent?'' Gail asked as she rolled her eyes. ''Callaghan, not Swarek.''

''You slept with Luke?'' Andy's voice went up an octave.

Gail shrugged and looked around the bar. ''After Chris and I broke up. It was sort of like friends with benefits. Only we weren't really friends, so I guess we just had the benefits.''

Andy looked a little shocked, but didn't blame Gail for anything. She had no feelings for Luke anymore. ''Okay.'' Andy couldn't really think of a better response.

''I don't mind you sleeping with Collins,'' Gail said. ''Sleep with him all you want, I'm done with him.''

''He thought you left for France Gail,'' Andy defended Nick. ''He couldn't know that you were here waiting for him.''

Gail huffed and shook her head. ''It was the second time he left actually,'' she argued. ''And I don't want to be with someone who can't keep his eyes off someone else.''

Andy turned her gaze to her drink and refused to look up.

''It's okay Andy. I don't really blame you for anything. Nick is not a bad guy, but he is kind of a loser.''

''What do you mean?'' Andy asked.

''He left me twice,'' Gail stated.

Andy snorted. ''His loss,'' she said. ''His ego is kind of bruised now that he turned you gay.''

''What the hell is wrong with people?'' Gail yelled out. ''It's 2013. I go out with a girl a few times and I'm gay?''

''You're not?'' Andy asked.

''I'm having fun,'' Gail answered. ''Innocent fun where nobody is going to get hurt, but where everybody has a good time.''

''Sounds good to me,'' Andy replied as she bottomed her drink.

Gail sighed dramatically. ''Go and get Swarek back. I don't like Marlo. I want Noelle to come back. Maybe if you hook up with Swarek again, Marlo will leave.''

Andy snorted and shook her head. ''Apparently she's easy,'' she told Gail. When Gail looked at her with a raised eyebrow, Andy explained herself. ''I talked to Sam a week after I got back. I asked him why he chose her now. He told me that she wasn't complicated, she is easy, she's fun to be around and she isn't me.''

''Swarek is an idiot,'' Gail commented. She looked over her shoulder and saw Holly enter the Penny. ''I'm gonna go.''

When Gail stood up Andy stopped her. She was lost for words for a moment. ''Gail, just..'' Andy took a deep breath and looked her friend in the eye. ''I am really sorry for sleeping with Nick. I always told myself that I wouldn't do that with an ex of a friend.''

''Andy, seriously,'' Gail stopped her. ''I get it, okay? You were lonely and he has been the only person in your life for six long months.''

''Nothing happened while we were undercover,'' Andy defended herself. ''I know you and me weren't that close when we just started here. So when you slept with Luke things were a little bit different. But you really are one of my best friends.''

''Andy, stop. I'm not exactly a girl code kind of girl, okay?'' Gail glanced behind her back and looked back at Andy. ''We done here?''

Andy chuckled and nodded. ''Yeah. You girls have fun.''

''Thank you!''

When Sam finally finished his paper work he looked up at Traci. ''Time to go home Nash,'' he said while he yawned. ''It's been a long day.''

Traci checked her watch and sighed. Leo would be in bed already. ''Maybe I'll just see if I can find some new leads for the McGrey case,'' she told Sam.

''Nash,'' Sam warned. ''We've already worked twelve hours today. You need to go home, kiss your son goodnight and get some sleep.''

''My son is already in bed,'' Traci argued.

Sam shook his head and looked at the woman who was engaged to his best friend only a year ago. ''You've got to take some rest.'' Sam shut off his computer. ''I know it's easier to come to work and not think about everything that has happened...''

''It is,'' Traci agreed as she put on her coat. ''It seems like you got the same attitude, only we both play it a little differently.'' Traci took a deep breath. ''She still misses you, you know that?'' Sam swallowed and looked down at his desk. ''I'll see you tomorrow,'' Traci quietly said as she made her way out of the office.

Sam stayed in his seat for a while and then headed for the locker rooms. When he checked his phone he noticed that he had three missed calls, all from Marlo. He also had two texts from her. In the first text she asked him when he would go home. In the second text she asked him to come to her place. She felt miserable and wanted him around.

Sam made a fist with his hand and let his knuckles turn white from the pressure he put on his fingers. He didn't want to go to Marlo's place, but he knew it was probably better if he went. Not going over to your sick girlfriends apartment seemed like the wrong move.

So Sam showered quickly and went to Marlo's place by cab. He got in with the spare key that she had hidden so he could let himself in. He immediately went to her bedroom, not knowing what else he should do in her apartment alone. He never felt at home at her place. Her place actually looked a lot like his, so the fact that he didn't feel at home was a little bit strange. Marlo wasn't really the decorating type, so her place was pretty basic.

As soon as he walked into her bedroom, Marlo turned around. ''Hey,'' she weakly said.

''Hey,'' Sam replied. He sat down next to her and when she grasped his hand he looked at their joined fingers. ''Feeling better?''

Marlo shook her head no. Sam put his hand on her forehead and felt that she was a little bit warm. ''I'll go make you something to drink,'' he told her. ''Did you eat at all?''

Marlo shook her head again and coughed. ''Afraid I'm going to throw up again.''

Sam nodded and let go of Marlo's hand as he stood up. ''Well, it's probably better if you eat something anyway.''

He made her something simple to eat and brought her a glass of water. While she was eating he excused himself to clean up the kitchen. The kitchen wasn't even that big of a mess, but somehow he just couldn't sit in awkward silence. McNally had really rubbed off on him.

When Marlo finished eating she let herself fall back into her pillows. Sam took her plate and glass away and came back with a bottle of water. '"For if you get thirsty,'' he explained. ''I'm going to head home.''

Marlo sat up again and looked him in the eye. ''Can you stay?'' she asked. ''I don't want you to get sick, but if I'm contagious I probably already infected you.''

Sam really didn't want to, but couldn't find any arguments. ''Sure,'' he answered. When he got under the covers Marlo pressed a kiss to his cheek.

Marlo nodded off pretty quickly. Sam however spent the entire night awake. He kept wondering how he got here. How did his life become this messy?

''McNally, Collins, my office,'' Frank barked out before parade.

Andy threw a puzzled look at Nick, but he seemed just as surprised as she was. Together they walked towards Frank's office. When they entered he told them to sit down. ''The drug squad has requested you,'' Frank started.

Andy's eyebrows went up and her breath quickened. She couldn't leave everybody behind again. She was still processing everything that happened the last time she did that.

Frank probably noticed her response, because he immediately filled in some blanks. ''It's no long term undercover. Just an in and out kind of thing. Make sure the deal is done, get it on tape and get out.''

''Why us?'' Nick asked. He knew that there were a bunch of people that were specialised in that sort of thing. Even after a six month's operation they were still undercover rookies.

''Nobody else is free and you two proved that you can pose believable as a couple,'' Frank explained. ''It would have to be tonight.''

''I'm in,'' Nick immediately said.

Andy swallowed and looked at Nick. She knew he would have her back no matter what. She owed him the same. ''Me too.''

Ten hours later Andy walked into the male locker room. Nick was supposed to be outside already, but he didn't show up. When she heard vomiting sounds from the toilet she knew enough.

Nick came out and he looked awful. ''You can't go in,'' Andy immediately said. ''It's too dangerous like this.''

''We'll be fine,'' Nick answered. ''I probably got it all out now.''

Andy shook her head and blocked Nick's way. ''There's a virus going around the station. It's not a 24 hour thing from what I've heard. You need to have your head in the game tonight, if you don't we're both in danger.''

''What do you want me to do?'' Nick asked. ''They are counting on me and you are not doing it alone.''

Andy sighed and watched as Nick rubbed his stomach. ''We'll go talk to Frank,'' she said. ''No discussion Nick, this thing is too dangerous to go into like this.''

Frank agreed that it wasn't a good move to sent Nick in. They needed to find Andy another partner and they needed him fast. Frank told Andy to go finish her make-up, they would find her someone.

Half an hour later Traci walked into the female locker room. She had an apologetic look on her face. ''What?'' Andy asked. She knew that Traci and Sam were working with the drugs squat on this case. ''Don't tell me it's off?'' Andy pointed at her excuse for a dress and hooker boots. ''I didn't put this on for nothing, did I?''

''No, it's on,'' Traci explained. ''Thing is, we needed to find you someone fast. And we needed someone that already knew the case because there's no prep time.''

''God,'' Andy groaned. ''Sam's going in with me?''

''It was his idea.'' Traci shrugged her shoulders. ''Frank agreed that it was the smartest moves. The two of you know each other's moves and you've always worked together well.''

Andy shook her head and slammed her locker closed. ''Why the hell did he volunteer?'' she asked. ''Doesn't he realize that it's going to be awkward to work together? We don't need awkward. We need to be believable as a madly in love couple.''

''Well, I don't think that's going to be a problem,'' Traci joked. Andy shot her an annoyed glare so she shut her mouth. ''It's time Andy, we need to get going. Just focus on getting the deal done. I'm on the cover team, so I'm right behind you.''

Andy walked out of the locker room and saw Sam standing in Frank's office. Apparently they were done, because Sam came out and walked down the stairs. ''You ready?'' he asked.

''Ready as I'll ever be,'' Andy muttered.

Besides the fact that Sam took Nick's place, nothing changed. Everybody knew what they were supposed to do, so Andy and Sam got into the car together.

''You know how it's going down?'' Sam asked.

''Yes,'' Andy replied. ''I'm there to back you up. You do the talking. We met in Vancouver and ever since we met, I tag along with you.''

Sam nodded and focused on the road. ''Good. You can do this McNally.''

Andy didn't answer but just stared out of her window. ''Why did you volunteer?'' she asked after a minute of silence.

''I was the best guy for the job,'' Sam truthfully answered.

And that was true, he was. He also didn't trust anybody else to have her back though. He knew this was a potentially dangerous operation. With Collins dropping out, he knew he was the only one that knew Andy well enough to be her partner.

As soon as Sam parked the car he checked the mirror to see if the cover team was in place. ''You know the sign?'' he asked just to be sure she was comfortable with it.

Andy sighed and tried to avoid Sam's eyes. ''Yes,'' she answered. ''As soon as the deal is done, we kiss, they bust us.''

Sam nodded and put his hand on her knee. ''You can do this,'' he said again.

Andy didn't answer him, but just opened the door. When they walked towards the area where their meeting would be, Sam grasped her hand.

When their hands made contact, Andy jumped a little. She knew she had to look like she was comfortable with him, so she forced herself to relax.

''You cold?'' Sam asked when Andy shivered.

Andy didn't really know what cold was whenever Sam was near, but she couldn't exactly tell him that. ''This dress doesn't cover much,'' she replied. ''It gets a little chilly.''

Sam almost groaned when she mentioned the lack of length on the dress. Even though Sam would never want her to go out like this, she did look incredible. She was showing off her long legs and her dress hugged every curve on her body just right.

Sam's grip on Andy tightened when their targets came into sight.

''You John?'' one guy asked.

''That depends, you have what we agreed on?'' Sam shot back. He looked at the man that moved to Andy's right. He didn't like the way that the guy was looking at her at all.

''Who's this lovely lady?'' the man asked.

Andy turned around a little and crossed her arms in front of her chest. ''I'm his girlfriend.''

''Nice job John.''

The guy that talked first stepped in. ''As lovely as it is to get to know each other, I have other stuff to do.'' He nodded towards a van that was parked a view steps from there. ''Your product is in there. You got my money?''

''Right here,'' Sam said as he held up a bag. ''Need to check the product first though.''

''It is a shame that we can't just trust each other, is it?'' The guy smiled and nodded at Andy. ''Let your girl check.''

Sam looked at Andy and then looked at the van. He knew that the cover team would be able to reach her if something was up and he didn't see anything out of the ordinary, so he gave her a small nod.

Andy slowly walked towards the van and opened the door. She left the door open and opened a view bags that were lying in the back of the van. All the bags were filled with drugs.

She walked back to Sam seductively and smiled. ''Looks like we're going to make a lot of money babe,'' she said with a small grin.

Sam nodded and looked back at the guy that apparently was the one doing the talking. ''You ready to give me the keys to that van?''

''Need my money first,'' the guy answered.

Sam handed over the bag and waited for the keys. As soon as he got them he turned around to face Andy. ''Where did you say you wanted to go on a vacation again?'' he asked with his typical undercover smirk. ''It's all possible now.'' Sam dipped his head down and when their lips connected things finally felt right again.

It was supposed to be a chase kiss, but neither one of them broke it. Andy gripped Sam's jacket and pulled him closer while he slipped his hands across her waist.

They were forced to break apart when their colleagues ran towards them. Everybody had their guns out and lights were flashing. The deal was done, it was time for the bust.

While Andy was being cuffed by some guy she didn't know, she looked at Sam. He looked just as confused as she felt.

The night before she swore that she was done with him, but that kiss proved to her that she wasn't. Every fiber in her still craved him.

Sam looked at Andy and knew that he needed to be honest with himself. He wasn't over Andy and he doubted that he would ever be.

A/N: I was planning on letting Sam stay with Marlo for a while longer, but then I figured that the show would probably torture us enough with that.

Hope you enjoyed, please review!
