SAY YOU WON'T LET GO CHAPTER 1

A/N: So I really have no right posting this when I'm months behind on updating all my other fics, but this song is so beautiful and the moment I heard it I just got this whole Linstead vision in my head! the scenes aren't all in a cohesive kind of order, they're sort of like little seperate scenes within the story. I hope you like it!

This was originally going to be a one-shot but I now have roughly 8-10 parts planned. Most of this is AU, but there are some bits taken from the show!

[ Credit to James Arthur for his song 'Say You Won't Let Go' which has been on repeat as I wrote this :D ]

Enjoy!

I met you in the dark
You lit me up
You made me feel as though
I was enough

Jay Halstead walked into Molly's with apprehension. The last time he had been here, he was an undercover agent seducing one of the owners to help him arrest a criminal, and now he was meeting that same owner's brother. He didn't realise Antonio was serious when he said he could choose where he wanted to go after taking a bullet. But when he called him this morning saying there was a position available in Intelligence and it was his if he wanted it, Jay had never answered 'yes' so fast in his life. He wanted this, more than he'd ever wanted anything.

"Halstead!" Antonio cheered as he spotted the young man.

Jay smiled at his partner, reaching out to shake his hand but Antonio simply shook his head and gave him a quick hug. The act surprised Jay but he accepted, his hand quickly patting Tony's back in a 'manly' manner.

"This is Sergeant Voight, he runs IU." Antonio says as Jay looks behind him at the group of people sitting on stools at the table.

"I know, it's good to meet your Sarge. Thank you for the opportunity." Jay said shaking Voight's hand.

"Just don't screw up, one mistake and you're out. I don't tolerate incompetence." Voight said shaking squeezing his hand a little too firmly for Jay's liking.

"Of course, sir."

Hank nodded and turned to his unit "Don't get too rowdy. I want you all in the office at 8am tomorrow morning." He said before walking to the exit.

"Don't mind Hank, he can be intimidating at times but he's a good boss. I'm Alvin Olinksy." Jay smiled at the man before him, taking in his greying hair and tired face. He didn't want to be here, but Jay figured he had been brought along to introduce himself.

"Jay Halstead." He said quickly, shaking Al's hand as well.

"Alright, now that's done I'm heading home." He chuckled and began to follow after Hank.

"Oh come on Al!" the blonde woman at the table yelled "It's my one night without the kids, you gotta come celebrate."

"That's nice, but this is my one night with my daughter Jules. I'll buy you a drink next time." He said smiling at the woman before quickly retreating.

"This is my partner Jules, and our IT whiz Sheldon Jin." Antoinio said, introducing Jay to the other members of the team.

Jay waved politely, taking a seat next to Jin as Antonio slid a drink in front of him "First one's on me. Welcome to Intelligence."

Jay raised his glass to clink with the rest of his coworkers. He looked around, frowning slightly.

"Uh, isn't there supposed to be six of us working under Voight?" He asked.

"Your partner's running late, as always." Jules chuckled "She should be here soon enough."

Jay smiled and nodded his head again, taking a sip of his drink as he waited for his partner to show up.

LINEBREAK

He was definitely buzzed.

The room was starting to blur around the edges of his eyes, and he could feel the lightheaded feeling of intoxication slowly seeping through his body.

As part of initiation, Jules had insisted that not only Jay shout a round of drinks, but that he had to prove his 'worth'. Also known to Jay as 'let's see how much alcohol the new guy can take before he's too fucked out of his mind for work tomorrow'.

The bell above the door of Molly's rang out, and Jay turned his head at the sound. He saw her through the crowd of people, his breath hitching in his throat and his eyes suddenly coming into focus.

She was, without a doubt, the most beautiful woman he had ever seen. Her shoulder length dark brown hair matched the colour of her eyes, and Jay couldn't help but feel warm from the smile she emitted.

"I see you spotted your new partner." He was brought out of his thoughts at Jin's words.

"What?" he said shocked.

"Erin. That's your partner." Jin clarified.

"When I spoke to the desk Sergeant, she said I would be partnered with an Eric Lindsay."

The group burst out laughing "Trudy's got a twisted sense of humour. You'll learn to love it. Anyways, that is your very much female partner, Erin Lindsay."

Jay chuckled softly. Only he could be attracted to the one woman in this bar that he couldn't have. They would be working together, it would be unprofessional.

'Although' he thought 'It is a perfect conversation starter.'

"I'll be right back." He said before getting up from the table and heading to the bar where she stood, talking to an older gentleman behind the bar.

"How's it going tonight Hermann?" Erin asked, and Jay felt his heart skip a beat at the melodic tune of her voice.

"Drinks are flowing and customers are happy." Hermann smiled.

"Ah, drinks are flowing. And so is your money." She said and Jay could see the playful smirk on her lips.

"Well." Hermann drawled out "It is definitely a bonus."

Jay watched as Erin shook her head, laughing at Hermann's antics as the man passed her a beer before heading off to serve another customer. This was his chance.

"Hey." He started as she turned to face him "Uh, you're-"

"Not interested." She said, cutting him off and walking towards the table her unit was sitting at.

Jay followed after her "Bit presumptuous aren't we?"

Erin stopped and turned around to face him "What? You're telling me you just came over to talk? Get to know me?"

"Actually yes." He replied "Believe me sweetheart, if I was hitting on you, you'd know it."

"I'm sure I would." She muttered sarcastically.

"Look, I just wanted to come and introduce myself, that's all." Jay said raising his hands in the air as a gesture of defeat.

"And why do I find that so hard to believe?" She said narrowing her eyes at him.

"Well maybe, deep down, there's a part of you hoping that I was coming over to ask you out." He smirked "And now, you're disappointed to know that I had no intentions of doing so."

"Please." Erin rolled her eyes "If I wanted to go out with you, you'd know."

"Oh I'm sure you would." He chuckled "I'm sure you're very skilled at getting what you want."

Erin narrowed her eyes at him "Okay, you know what. I think it's time you left."

"Why would I do that?"

"I mean, unless you want everyone in this bar to see you getting your ass kicked by a woman." Erin said with a shrug.

"Oh I reckon I could take you sweetheart." Jay smirked.

Erin rolled her eyes with a groan "Ugh, you're such an asshole."

Jay looked at her confused "I'm sorry, why am I an asshole? I came to have a friendly conversation, and you practically bit my head off-"

"Look, I'm just here to meet this guy and go okay? I just want to get this over with so I can go home and shower and sleep, and I really don't need some guy hitting on me right now."

"I was never hitting on you Erin."

"Look, I don't have … Wait a second." She looked up at him surprised "I never told you – Who the hell are you?"

"Well, if you had let me finish introducing myself you'd know wouldn't you?" Jay said cockily.

"Look man, I'm a Chicago police officer, I'm not above arresting you right now."

"Damn, I knew you wanted but me but I wasn't expecting that. It's always the quiet ones." He said and Erin opened her mouth to yell at him but he quickly continued "Well I don't think Voight would be very impressed if you arrested your partner, but hey if you're into that kinky shit go for your life." He said sticking out his hands for her to cuff.

Erin looked at him shocked "You're Jay?"

Jay nodded, trying his hardest not to laugh "It's a pleasure to meet you, partner."

Before she knew what she was doing, her hand had already come up to punch him hard in the shoulder.

"Ow!" He whined reaching his left hand up to his opposite shoulder "Dammit Lindsay, what the hell?"

"You're an ass!" She hissed "Why didn't you tell me you were my partner!?"

"Well you were the one who assumed I was some cocky asshole trying to hit on you." He said raising his brow at her.

Erin felt her cheeks flush and her face grow hot "Sorry about that … You still could've said something."

"I tried!" He laughed as Erin shook her head exasperated "Okay, let's refresh."

Erin frowned as Jay stood up straighter, extending his hand out to her "Hi, I'm Jay Halstead. Apparently you're my new partner."

"Erin Lindsay, it's nice to meet you." Erin smiled politely shaking his hand.

"So, can I buy you a drink?" Jay asked as they began walking to their table together.

"You trying get on my good side Halstead?" Erin asked.

"Oh believe me, alcohol isn't how I'd do that." Jay said cheekily.

Erin rolled her eyes again "Let's get one thing straight right here, I drive."

Jay shrugged in return "Fine by me. Makes it easier when you take me home tonight."

"Halstead." Erin sighed, rubbing her forehead in frustration.

"Relax Lindsay, I'm just playing with you." He replied "You can drive, but I pick the music."

Erin thought about it for a moment, giving in to the puppy eyes he was giving her "… Fine."

Jay chuckled throwing his arm around her shoulder. "Something tells me this is the beginning of a beautiful partnership."

Erin simply scoffed before shrugging his arm off her and walking ahead of him, Jay watching her body sway from side to side as she walked up to their unit.

"This woman's going to be the death of me." He groaned to himself before heading over to join his new coworkers.

A/N: Okay, so I'm not 100% confident with this ending part but I've been trying to write these one shots for six months now. Part 2 is already done, and the others have been started but this one was the one I struggled with the most.

I hope you guys liked it anyways, please leave me a review and let me know what you think!
