Thanks to Kat, as1999 and Em for reviewing next ud should be Fridayish if I get a fair few reviews :P XxJilly

Abandoning the car a few lanes over from Chris's, Emma and Will emerged from the car and tailed him to the huge gaping mouth of Kings Cross Station. Turning to smile at Will Emma looked around, a crush of people surrounding her…and Will nowhere to be seen. Panic rising from her stomach Emma froze, it was like when you were little and you got separated from your parents in a crowd. The only person who could protect you, who knew where you were going was gone and you had to rely on yourself. Turning on the spot faces in the crowd merged into one, her head becoming heavy, her vision blurred as she tried to stay calm.

Fingers closed around her wrist and she turned, ready to slam her fist into whoever was trying to take her away but instead she melted into his arms, her cheek pressed tight against his chest as she finally exhaled again, not having realised she'd been holding that breath. "Don't you ever scare me like that again." She murmured as his hands closed tightly around her.

"It was you that left me." Will replied, his breath blowing a path through her golden brown locks.

"I know." She whispered, her mind very much in the past, her words having nothing to do with the present.

Pulling slowly apart Will ran his hand down her slender arm, his fingers looping through hers. "Stay close." He said as he pulled her over to the ticket barriers where Chris was fumbling with his tickets, trying to sidestep the security man who wasn't having any of it.

"I've got them here…I've got the bloody tickets alright." They heard him mutter angrily as he pressed them into the man's hand. Letting Will drag her forwards to the turnstile gate Emma yanked out her Oyster Card, swiping it across the flat yellow panel so the red cross on the gate turned into a green tick, letting her through to join Will who was standing watching her carefully.

Rolling her eyes she tucked her hand through the hoop of his arm. "And I thought that you were meant to be observing Chris." She giggled as they wove quickly through the crowd, following the yellow baseball cap that was bobbing up ahead of them. "Where's he going?" She asked for the third time in a matter of minutes as they took another flight of steps down under the city.

"Well if we knew that then we wouldn't be here would we?" Will smirked as Emma's sharp elbow jabbed between his ribs.

"Yeah, yeah smart arse keep talking."

"Oh I will."

"You will?"

"Yeah I will."

Turning as she stepped out onto the platform Emma fixed Will with her stare. "You know you're wasted on the day job mate." She smiled up at him. "You should be a professional nuisance."

"You wouldn't have me any other way." Will replied, his hand on her waist pulling her into him as a large man barged past, his suitcase catching the back of Emma's leg.

"Shame you won't have me at all." She whispered sadly, her words blown out of her mouth and in the opposite direction from Will as the tube train whistled to a stop in front of them, a rush of cold air enveloping them all.

Running her finger up and down the row of keys on her office phone Sam sighed. She knew the number off by heart, she always had but still she couldn't pluck up the courage to dial it, she probably never would. He always phoned her…it was never the other way around. But now his calls had stopped…where did that leave them?

The knock on the door brought her from her thoughts and she quickly slammed the receiver back down into it's cradle, her photo in her hand being stuffed into her desk drawer as Stevie poked her head around the door, grinning at her superior.

"Jus' wanted to know if you'd heard from Emma and Will yet?" She asked, her eyebrows raised as she took one look at Sam's flushed cheeks and her guilty smile.

"No…no word from them recently. Emma texted me about twenty minutes ago saying that Chris had gone into Kings Cross Station but I've had no word since. Mickey assures me that they're perfectly capable though…if a little hot headed at times." Sam sighed as she leant back in her chair.

Nodding Stevie tipped her head back so it was resting against the doorframe. "Pretty good description of them two of them. So who were you on the phone to that's got you so guilty?" She asked slyly, Sam's mouth opening before she came to her senses.

"Nothing…nobody." She covered up, biting her lip as the guilt literally poured off of her.

"Sure, sure I'll leave you to get back to Nobody then. He's clearly got you in a spin." Stevie grinned, closing the door behind her before Sam could protest otherwise.

Emma clung tightly to the pole beside her as the tube jolted back and forth, the contents of her stomach being hurtled about at mixed speeds every time they drew into a tube stop. "Take it your not a 'tube person' then?" Will asked, a smirk playing on his lips as Emma turned a pale shade of green and leant heavily against him.

"What do you think?" She raised an eyebrow as Christopher gathered together his belongings and stood expectantly at the door of the tube. "This is our stop." She nudged him over to the door so they were standing two behind him. Hopping down off the train Emma turned to find Will's chest in her face as he continued walking.

Laughing he peeled her off of him and flicked her ear annoyingly. "If you wanted a hug Em you could just have asked."

Growling Emma turned and stomped away, angry that Will was playing to so cool and that she was such an easy read. His fingers in hers though calmed her near instantly, sending little electric shocks up and down her arms as he steered her through Liverpool Street Station. The familiar routine, Police Officers milling around, Oyster Cards ready and waiting, shoving their way through the turnstiles and standing at platform after platform came like second nature to Will and Emma, both Londoner's through and through. Eventually an hour after they'd arrived at Kings Cross Emma clambered onto a train after Chris and flopped down into a spare seat gratefully. "Hey what about me?" Will moaned; his legs were aching too.

Laughing Emma budged over so that Will could perch next to her. The light relief they experienced on their legs however was short-lived as an elderly woman was helped up onto the train. Nudging Emma to her feet Will smiled at the woman. "Here…have our seat." He offered kindly, pulling Emma over into the main standing area between the carriages.

"Awww the perfect gentleman aren't you?" Emma laughed, tweaking his cheek as he blushed and looked down at his scuffed up trainers.

"Shu'up." Will muttered, staring out the window as the sights of London flew by them as they grew closer and closer to wherever Chris Martin was headed.

Emma stood with her back to Will, his chest gently pressing against her every time he breathed. Her eyes slid slowly around the carriage, watching as men and women, most of them dressed in smart suits spoke on their phones, read magazines and newspapers or sat plugged into their own little world's on their Ipods. As she watched these people she wondered…was this what her life would have been like if she'd followed the path that her Dad had set out before her? Would she be a lawyer, dressed to the nines with not a minute to spare in her day?

Falling from her daydream she blinked. Chris Martin was staring right at her and Will, the two people who stuck out like sore thumbs, the only two people on the whole train who weren't already preoccupied with some important task that couldn't wait just another ten minutes until they disembarked from the train. Turning slightly to face Will she leant up and breathed in his ear. "Look busy."

Before she even had time to blink she felt Will's soft lips on her own, the space between them closing as he wrapped one of his arms around her waist. Her hands stayed limp by her sides as Will's other hand caressed her neck, his lips still roving over her own. God she hoped this torture would never end…

Pausing slightly Will let go of her, his eye line over the top of her head so she couldn't interpret his emotions. Looking up at him, a small smile tugged at her lips. Now if that was just in the line of duty he was a very dedicated police officer. "You know that wasn't really what I had in mind." She whispered, her breath tickling his neck.

"Right." Will sighed, confused as she blew hot and cold on him again…or so he thought.
