A new story because I had a stroke of inspiration - this chapter is short and I don't know how long this will be, but I needed something to keep me busy in quarantine. Enjoy and let me know what you think!

Season 4-ish

"Coffee's hot!" Jay called, pouring the steaming liquid into two matching grey cups, one with a small chip in on the edge. He reached into the fridge and pulled out the almond and the skim milk before carefully scooping a teaspoon of sugar into the chipped mug, along with a splash of the skim milk.

"How come I get the chipped cup this morning?" Erin pouted, accepting the mug from her boyfriend from across the breakfast bar. She didn't wait for his reply before lifting the mug to her lips and taking a grateful sip.

Jay rolled his eyes and placed the milks back in the fridge. "Accidentally put the sugar in that mug this morning."

"Yeah right. You just didn't want the chipped mug." She took another sip, "It's good."

"I'm good," he replied, winking before finally getting a good gulp of his own coffee from the non-chipped mug. He paused, the mug still at his lips. Erin was clad in a pair of her favorite black jeans, with plaid flannel top tucked in at the waist fastened with a black belt. "Is that…my shirt?"

Erin raised her eyebrows suggestively. It was indeed her boyfriend's shirt, plucked directly out of his bottom dresser drawer. It has been a while since he'd last worn it, and it wasn't like the guys she worked with would remember. Plus, it had the added benefit of smelling like her partner. Even though they spent most of the day together, there was something about wearing her boyfriend's clothes in public that turned her on a little bit, and also made her feel like she was wrapped in his arms even when they were in the field. "I thought it would look good with these jeans. And it's cold outside today." She offered a cheeky smile, "And you gave me the chipped mug this morning. I deserve something in return."

"Well, it looks better on you," Jay shrugged, taking another sip of his coffee, "Though I think my shirt would look better on our bedroom floor."

"Oh yeah?" She placed the mug delicately on the counter and carefully undid the top button, "Maybe it would look better on me if I wear it like you do? Fully open?"

"Mm-hm," Jay nodded, rounding breakfast bar and unbuttoning the second button on his shirt, "Far more comfortable that way." He leaned down and pressed a kiss to her lips, tasting the sweeter coffee on his.

Just as Erin was about to kiss him again, her cell phone chimed on the kitchen counter. "Ugh," she groaned, fumbling with the device as Jay kissed her neck, "Shit. It's a CI of mine."

"Can they wait?" Jay mumbled into her collarbone, "We have some time before we need to be at the district."

"Something about a shipment of guns from a local dealer," she read, "It's Landon. Maybe we'll get a good tip out of this."

"Landon? As in the guy you used to…" Jay trailed off and pulled back, not wanting to finish his sentence as Erin put her hands on her hips defensively, "He's a CI? One of your CIs?"

"Yes, he's one of my CIs, and he's clean," Erin responded, "I told you I bailed him out when the 23rd picked him up over the fourth of July. He gave us that tip that lead to busting that dealer down on Cermak."

Jay furrowed his brow. "Didn't realize it was the same guy," he mused, reaching back across the counter for his mug, "Thought that tip came from someone who worked at a coffee shop downtown." He gulped down the last of the liquid in his mug before he said anything else. If this tip was going to lead to a case, he was going to need more coffee.

"Same guy. Last I heard he still works at that coffee shop with the blueberry muffins you liked so much." Jay managed a soft grunt in recognition. He did love those muffins, but he really didn't love that Landon was in Erin's life, even as a CI. "You don't have anything to worry about, Jay," Erin said lightly, re-buttoning her – Jay's – shirt, "really. That life is behind me now."

"I know babe, I just," Jay trailed off again, "Want you to be safe," he finished.

"I will be," she promised, tucking her service weapon on her hip and grabbing her keys off the counter. "I'll meet you at the district in an hour, tops."

"I might pick up a bagel on the way there. You want the usual?"

"Always," Erin replied, turning around to kiss his lips once more.

"Wait," Jay caught her arm as she turned to get her coat.

"I gotta go babe." He nodded in understanding and buttoned another button on his top. She rolled her eyes, "Really?"

"Can't be too careful," Jay winked, "I'll see you in an hour."

Erin pulled up to the parking garage and quickly checked her reflection in the rearview mirror. It had been months since she'd last seen Landon in the holding cell of the 23rd district. She'd been his last-ditch effort to avoid jail time for possession, so she vouched for him with the understanding that she owned his ass, and that he needed to get clean.

He'd provided a good tip to Intelligence that had checked out, so she had a reason to trust him. But now he was ten minutes late and Erin's stomach grumbled. Jay likely had a toasted everything bagel waiting for her on her desk and maybe even another coffee. He was so good that way, always trying to anticipate what she needed. After moving in together, their relationship had only gotten stronger. Erin smiled at the domesticity of it all – coffee in the morning, simple late night home cooked dinners after they got back from work far too late in the evening to construct anything gourmet, his shoes lined up next to hers - not to mention the added benefit of his comfy clothes always being within reach.

Erin glanced into the wing mirror to see a familiar lanky ex hurry across the parking garage. She sighed and disembarked, leaning against the hood of her black Jeep as Landon approached. "Hi, Erin," he said breathlessly, sticking his hands in the front pockets of his jeans, "How is it going?"

"You texted me, remember?" Erin narrowed her eyes, observing her CI's jumpy mannerisms, "What's going on?"

"Got a tip for you," he leaned in closer and glanced around the empty parking garage, "A-are there cameras in here?"

"No," Erin replied confidently, "It's perfectly safe. So what is this tip that's got me across town when I need to be at work in fifteen minutes?"

"Guns," Landon replied, glancing around the parking garage again and leaning closer, "A whole load of them are being brought into the city from Canada, tomorrow morning at like four."

"How do you know this?" Erin questioned, "Gun running is a whole different league than a couple of kilos of heroin, Landon."

"Why-why would I lie?" he sputtered, looking around again, "The guy I used to sell for back in the day, he's bringing them in at five am tomorrow."

"A second ago you said four in the morning," Erin accused, "Are you jerking me around?"

"No!" he replied, "Four am, five am, same difference. I swear!"

"Any other details?" she probed, decidedly irritated, "Where is this all going down? How many guns are we talking about? And who is this guy you used to sell for, huh?"

"I can't give you the name. But I can tell you it's his first time running guns, so he's bound to be sloppy. Tomorrow morning, down by the lake. I-I can text you the address when I get it."

"You don't even have an address?" Erin sighed, "Look, Landon, I'm late for work. If you have an actual tip, let me know, otherwise-" She turned back to her car before something collided with the back of her head, knocking her out cold.

"Anything new today, boss?" Ruzek asked as Voight stepped out of his office, hands in the front pocket of his jeans, "Caught that double homicide over the scanner this morning."

"Yeah, they're passing that over to major crimes," Voight shrugged, glancing around the bullpen, "Anyone seen Lindsay?"

"Meeting with a CI," Jay supplied, emerging from the breakroom stirring a cup of coffee to accompany his bagel, "Said she'd be here in a half hour or so."

"Hm," Voight turned back to his office, "When she gets in, send her in here, will you?"

"Will do." Jay glanced down at his cell. It had been over an hour since Erin had texted him to say she was still waiting on Landon, and she hadn't replied to his last two messages, or picked up the phone when he called. Her coffee and bagel were definitely cold by now.

"Hey, you've reached Detective Erin Lindsay. Please leave your name and number and I'll give you a call back."

Jay hung up and cursed before getting up from his desk. "Sarge?" he knocked on Voight's office door. It wasn't like Erin to not reply, and two hours with a scumbag like Landon was two hours too many.

"What's going on, Halstead?" Voight looked up from his cell phone and sized up the detective in front of him, "Everything okay?" He narrowed his eyes, "Is Erin alright?"

"Actually, Sarge, that's what I wanted to talk to you about. She left this morning to meet with a CI and said she'd be back to the district in an hour, but it's been almost two and I haven't heard from her." Jay shifted nervously on his feet as Voight set his phone down and swallowed.

"People run late, Jay," he folded his arms across his chest, "You think this is something more than that?"

"She's meeting Landon. That guy she used to uh, hang with, back when she wasn't doing so great," Jay fumbled with his phone, "I guess he gave us a good tip a few months back and he's clean, but something about this is just giving me a bad feeling."

"Beyond the fact that he used to be involved with Erin?" Voight questioned, picking up his phone and dialing Erin's number.

"Hey, you've reached Detective Erin Lindsay."

"Beyond that. Really, Sarge, I just got a bad feeling." Jay glanced down at his cell again, no missed calls or texts. "She's my partner, I think I should make sure she's okay."

Voight hung up on Erin's voicemail, "Alright, have Mouse ping her cell. We'll go see what's going on."

Mouse was able to pinpoint Erin's location to the parking garage. "She's meeting a guy named Landon? This the same Landon who we picked up at her place few years back?" Kevin turned to Jay as the detective pulled into the parking garage, "Same dude who was icing his face with a bottle of vodka?"

"Same fucking guy," Jay muttered. "There's her car," He pointed as he turned onto the third floor, Kevin riding shotgun with Hank and Al in the Escalade behind. The sinking feeling in his stomach deepened as he didn't immediately see the familiar wavy brown locks of his partner within the car.

"I don't see Lindsay anywhere though," Kevin murmured, looking around the empty lot, "I don't see anyone."

Jay jumped out of the Sierra and approached Erin's Jeep, piece drawn. "Erin," he called, glancing into the driver's side window. "Erin!"

"Mouse said her phone was here?" Voight asked gruffly, looking around the empty lot, "She's not in her car?"

"Sarge! There's uh, some blood on the ground," Kevin said, crouching on the ground at the hood of Erin's Jeep.

Jay felt his blood run cold. "What?" he managed, lowering his weapon and rounding the vehicle. Sure enough, a few droplets of blood were sprinkled on the floor.

"This her phone?" Al piped up, holding up a smashed cell in his gloved palm. Voight swallowed thickly, immediately recognizing it to be Erin's.

"That's hers," Jay replied, "Oh my God."

"Get an all-call message out, blast it over the zone," Voight barked, "We have a missing Chicago police detective."

The first thing Erin felt was cold. Why was it so cold in her apartment? Did Jay leave the window open or something? She shivered violently. God, even the bed was freezing. And uncomfortable. This wasn't her bed. Did she pass out on the floor? She attempted to push herself up before realizing her hands were tied behind her back. Landon. Erin forced her eyes open, overwhelmed by the darkness she was met with.

She was in a basement of some kind, the floor and walls made of concrete, covered in dirt and what felt like tiny sharp rocks that were imprinting her skin painfully. Erin was laid against the wall in a heap, her face on the ground and mouth gagged. She groaned and her stomach turned as the memory of someone cracking her in the back of the head came rushing back. Her head was throbbing. Whoever had struck her had gotten her good.

A small reflection of light illuminated her service weapon and badge that sat on a stool across the dark room. Her captors hadn't been stupid enough to bring her cell phone with her unconscious body, but they certainly weren't smart enough to ditch her piece. If she could get to it, she might have a chance.

Erin looked around, trying to discern if there was an obvious exit or anyone in the basement with her. She silently cursed herself for being careless enough to let fucking Landon and whatever idiot he was working with get the jump on her.

Suddenly, the room was illuminated as the door at the top of some very rickety wooden stairs swung open and heavy footsteps descended into the cold basement. "Oh finally, you're awake," a deep voice chuckled, "Good to see you again, Erin."

Sorry this chapter was short! Beginning was inspired by a thread I saw about Erin & Jay wearing the same button down.
