Author's Note: My first one-shot, it's actually a songfic, based on Katy Perry's Waking Up In Vegas. This is also my first attempt at romance which I am not good at; I am perhaps the least romantic person alive according to everyone that knows me.

Disclaimer: I don't own Taggart, Robbie and Jackie, or the song this is based loosely on.

As a detective Jackie had learned to remain calm regardless of the circumstances. It took an awful lot for her to panic, and, in the past when she had found herself face to face with some of Scotland's most notorious killers she had barely batted an eyelid. She had lost count of the number of times her life had been threatened and still she had kept her cool despite how bleak things seemed. It was why others found her so dependable; she always appeared so calm that it made their problems feel miniscule, however, that was not the case that particular morning as she sat on the end of the bed with her head clutched in her hands.

Her eyes were squeezed tightly shut giving the impression that she were in some form of physical agony and her breath was coming out in ragged gasps like she had just completed a marathon. Her hands shook and she fought desperately to regain control, to become the calm woman she had been. He couldn't see her like that, she wouldn't let him see her in a state of panic, close to tears and tugging at her hair like she had went mad.

Behind her, the plain white sheets rustled the sound almost exactly like that of paper, as its sole occupant stirred and began to wake from a deep sleep. Although her eyes remained shut she listened intently placing his every movement, knowing that he was rubbing his hands across his eyes and sitting up in bed, squinting against the early morning sun's harsh glare that flooded into the tiny hotel room. Several seconds of silence followed before he noticed her sat there with her back turned to him and when he finally did the room temperature seemed to drop by several degrees.

The only sound in the room was their breathing which Jackie was all too aware of and immediately tried to slow her breathing but that only succeeded in making things worse.

"Jackie?" His voice was unsure like he couldn't quite make up his mind if what he was seeing was real or not. To be honest, she didn't quite believe it. "What are you doing in here?" he asked gruffly and slowly she opened her eyes and turned around to look at him. He was sitting up straight with his dark eyes fixed on her, searching her face in an attempt to understand what was going on. His arms were wrapped around his knees which he had pulled up against his chest and, despite being in such a grave situation she couldn't help but allow her eyes to drift over him, her eyes lingering on his bare chest longer than was necessary before making their way up to his face.

"I can't believe this is happening." There was a note of desperation in her voice and it didn't go unnoticed. She sighed and ran a hand through her short dark hair, saying, "This just can't be happening. I don't know how.." Her voice trailed off and she tugged at her hair while Robbie just looked completely baffled which wasn't uncommon and certainly was not helping her in any way.

"Robbie, do you remember anything? Anything at all?" She fixed him with her gaze and her stared back at her for what felt like an eternity but could only have been several seconds. "Robbie?" she urged praying that he would just laugh and tell her it was all a dream, or, scratch that, a nightmare.

Her colleague didn't offer a reply, only reached out to the nightstand where he grabbed a half empty packet of cigarettes and a lighter. Their room was a non-smoking room but he didn't pay any heed to the signs placed in every available space or to Jackie's annoyance which she made no attempts of masking, instead making a loud 'tsk' sound as she watched him inhale deeply before exhaling slowly, a thin trail of silvery smoke escaping from his parted lips.

"I'll take that as a no then," Jackie snapped. She turned away again and pulled at the large grey shirt she was wearing until it reached her knees.

"Wait a minute, I don't have any idea what the fuck is meant to have happened but I hope you're not insinuating that this is my fault." The temperature seemed to fall again and she looked over at him being met by a look of anger that she had only seen on rare occasions whilst dealing with suspects.

"Yes, actually," she retorted and got up off the bed feeling Robbie's eyes tracing her every movement. Again, she ran her fingers through her straight brown hair like it might offer some form of comfort. Several minutes passed between them in which neither of them spoke until finally she turned to face him and settled her hands on her hips. "This trip was all your fucking idea. 'Oh, Jackie, you'll love it,'" she imitated his voice poorly, pulling a face as she did so. "Just look where that's got us!"

Angrily he crushed the cigarette in a tumbler from the bathroom and threw the sheets to one side. Robbie's eyes were fixed on her as he stood up, clenching and unclenching his fists like he wanted nothing more than to hit something, or someone and if she was being honest Jackie felt the same way.

"Well excuse me for wanting to do something nice for my girlfriend," he said gruffly his eyes narrowing. "But you can't see that can you? Everything's bleak with you."

"Nice? This isn't nice Robbie," she corrected. "We're in another country, thousands of miles from home, we've got no money and you remember nothing!"

"I tried and that's a lot more than you ever do." He stooped down and grabbed a pair of creased black jeans from the off-white carpet which he pulled on over his shorts.

"What is that supposed to mean?"

He fixed her with that same glare that could scare even the most hardened of criminals. "I don't think I need to explain." Regardless, he did, "I'm trying to do something nice, I wanted to make you happy, to get you away from Glasgow for a wee while. You work so hard and put up with so much that I just thought you deserve it, I'm sorry for being considerate." She frowned at the sudden sound of hurt in his voice, it was unexpected and she had to admit that she hadn't been expecting their reason for flying out to Las Vegas to be centred around her. For a moment she felt a tinge of guilt; he had put so much thought into their trip and she was being completely ungrateful, but that quickly dispersed and was replaced by rage again.

In an effort not to say something she would later regret she crossed to the window and looked out across the famous city with her arms wrapped tightly around herself. She leant her head against the window and sighed loudly.

"I just can't believe it," she said softly feeling his eyes burning into her back. "We've been together for what? A month?"

He didn't reply and, confused she turned, resting her back against the glass window to see his expression changing. It looked like a light had suddenly clicked on and it would have been funny if they weren't in such a dire situation.

"We got hitched last night?" he questioned just to be sure. Jackie nodded and he frowned. "Wow, this is just…" he trailed off, unable to find a word to describe their current situation. "When I thought about marriage I never thought it would be by some guy dressed up like fucking Elvis." Jackie suppressed a tiny smile at his grave humour.

"You're absolutely sure?" She nodded again and gestured to the chair by the dresser where a pale yellow folded piece of paper lay. As thought not taking her word for it he crossed to the chair and unfolded the sheet and proceeded to scan his eyes over it.

"What are we going to do?" she asked once he had finished reading.

"I'm calling Stuart," was his immediate response. "He'll know what to do."

Jackie scoffed and rolled her eyes. "And what exactly can he do? In case you've forgotten he's in another continent!"

"Oh, I'm sorry, have you got a better idea?" Robbie asked sarcastically, throwing the paper to the floor and crossing to the bed to retrieve a shirt. She didn't reply and he barked a laugh as he pulled a plain tight black shirt over his head.

She ignored him and quickly pulled on a pair of grey jeans that had seen better days. "This is your fault anyway," she told him, glaring at him as he sank down onto the bed and stared up at the ceiling.

"What?"

"Of all the places we could go you choose Vegas! You know what you're like with a few drinks in you," Jackie snapped and shrugged on a charcoal blazer over the baggy shirt.

"Well you could easily have said no," he reminded her.

"Yeah, well, maybe I should have. There are a lot of things I should have said no to." As soon as the words had left her mouth she regretted them, but she kept her face expressionless as she marched towards the door. She needed to get away from him, to clear her head, if she had had money she would have been on the next plane back to Glasgow but luck clearly wasn't on her side.

The bed creaked as he stood. "The feeling's mutual," Robbie said coldly. She felt tears sting the backs of her eyes as her hand fell on the door handle but she said nothing.

The door was half open when Robbie next spoke. "Look, Jackie, I didn't mean that." She paused, waiting for him to go on. "I'm glad I have you, I don't regret any of the time I've spent with you; the only thing I do regret is not acting on my feelings sooner. I didn't mean anything I said, I love you and I need you."

"I know," she said softly. "I love you too. I honestly do, but just all this- I didn't-"

He cut her off by stepping forward and taking her hands in his. "I didn't want things to happen this way, I feel like such an idiot. I can't do anything right, and it's too late now."

"What do you mean?"

Robbie's eyes met hers again and gently he brushed a stray strand of hair back from her face, his fingertips lingering on her cheek. "For a smart woman you're pretty slow." He gave her a small smile which, despite having known her for over ten years, still made her heart melt. His hand moved to his pocket and she watched him anxiously as he emerged with a small blue box, immediately feeling her throat tighten at the sight of it.

"It's exactly a month today since we first got together, and I know it's soon but I am in love with you. You're all I think about, I want to be with you every minute of the day," he trailed off and bit his lip, suddenly looking saddened. "I was going to ask you to marry me, but I suppose I was a bit late."

Jackie smiled up at him before pressing her lips to his, their previous argument completely forgotten about. When they separated she asked, "Do I really have a choice?"

"What would you have said?" he asked, still holding the tiny unopened box in one hand.

She kissed him quickly again suddenly feeling happier than she had in months. "Yes, but it just so happens that I'm already married to this gorgeous Glaswegian detective."

His face broke into a smile. "That's a shame, isn't it? So, this other guy, what's he like? Smart, sexy, the man of your dreams, just guessing here."

"Try vain," she said with a laugh as he pulled her in for another kiss.

Maybe their trip wasn't such a disaster after all.

Thank you for reading my very first one shot, hope you enjoyed it and reviews are greatly appreciated. I'm actually considering writing some more one-shots, most likely songfics again concerning Robbie and Jackie, only, of course if you like this. Criticism is also welcome.
