Stella and Kelly were cozied up on the couch watching a movie when they heard a knock on the door. Severide got up and opened the door to Sylvie.

"Hey, guys. Can I hang out here a bit? Casey and Gabby are at our house and I think they need some space," she lied.

"What?! Are they back together?" Stella looked at Kelly for confirmation, but he just shrugged. He knew what had happened the last time Gabby was in Chicago, but he wasn't about to tell them that.

"No idea, I just know I don't want to get in the middle of it," Sylvie said, flopping on the couch.

"Aw, I'm sorry, girl. Just when you were finally realizing your feelings for Casey!" Stella exclaimed. "Talk about bad timing."

Sylvie shrugged , turning her attention to the movie. Stella went to make popcorn, and Brett glanced over at Severide who had a a questioning look on his face.

"What?" She asked.

"You really think Casey would just get back with Gabby? After everything going on with you and him?"

Sylvie froze. What did Severide know? Casey had told him when they kissed, had he told him what else they'd done!?

"Popcorn is up, and I'm ordering pizza!" Stella said excitedly. "We should all go out tonight, too!"

Sylvie's face had a pained look. "Please Stella, no more clubs," Sylvie begged.

"Well where do you propose we go?"

Brett and Severide exchanged a grin, and Stella sighed. "Of course."

Hours later Casey walked into Molly's, hoping he'd find Sylvie there. She'd been gone the rest of the day, and he didn't want to overwhelm her by going after her. He wasn't sure what the right thing to do was, but he was trying to give her space. He walked in and breathed a sign of relief when he saw her sitting with Kidd and Foster... and Gabby. Seriously?

Casey headed for the opposite end of the bar, ordering a drink. He watched Sylvie at the end of the bar, talking to Gabby. This was seriously unfair.

Sylvie saw Casey walk into the bar and ordered another drink. Running into him eventually was inevitable. Gabby had sat with them, talking about her work in Puerto Rico, and Sylvie was doing her best to be interested. Gabby leaned in asking the girls,"So, who's Casey's new girlfriend?"

Sylvie swallowed her drink, forcing a smile. "What!? He has a girlfriend?!"

Emily had a confused look, and Stella's mouth dropped open a bit in surprise. She turned to Sylvie, a look of triumph on her face. Stella quickly asked, "what makes you think that?"

"Oh, he said he was seeing someone."

"Did he say who?!" Stella asked, her eyes still watching Sylvie.

"No? You guys don't know?"

"Nope." Sylvie responded, sipping her drink and glaring at Stella.

"Well, it sounds like he's really into her," Gabby said. "You know, I'm happy for him, really. He deserves everything he wants in life."

"Don't we all!" Foster laughed, taking a drink. "Now, if y'all will excuse me, I've got to meet someone." She walked off, meeting a handsome dark haired man at the door.

"I'm going to go talk to the boys, catch up with you guys later?" Gabby said, heading towards Cruz and Mouch. Brett and Kidd smiled and gave her a little wave.

Stella turned to Sylvie, slapping her arm. "You've been holding out on me!"

"Ow! No!" Sylvie rubbed her arm.

"It's you. It's gotta be you. What happened with you guys?!" Stella was buzzing with excitement.

"It doesn't matter," Sylvie groaned. "It was a one time thing, it meant nothing to him, that's what he said."

"ONE TIME THING!?" Stella hissed, "Holy shit, did you sleep with him!?"

Sylvie put her head down on her arms on the bar, mumbling into her sleeve, "I'm an idiot."

Stella's eyes grew wide, but she stayed cool. "Stop. Stop being dramatic. Forget all this crap you're making up in your head about how Casey feels and go talk to him," Stella demanded.

"But what if-"

Stella held up her hands to silence Sylvie. "No buts. Just talk to him."

Sylvie glanced towards the end of the bar to where Casey sat alone. She downed the rest of her drink, gaining a little liquid courage for the next conversation. Moving towards him, when he looked up at her she gave him a small smile.

"Hey," she said sitting next to him. "Can we talk?"

Relief flooded him. "Sylvie, you have to know, I didn't mean it like that, Gabby coming back made me realize I don't have feelings for her. I have feelings for you." He said quietly to her, his voice pleading.

"I don't know Matt, It's just all so complicated," she whispered staring at the floor.

"Sylvie, please. Give me a chance. I think you're amazing. And we could be something amazing." She looked up at him, his eyes begging for forgiveness.

"Take me home." She said, her eyes not leaving his.

Casey stood up quickly, heading for the door, Sylvie at his heels. As they passed Stella, she winked at Sylvie, who blushed. Climbing into Casey's truck was so familiar, she was giddy with excitement. And maybe she had a little bit to drink. As he drove, Casey's hand was draped across the seat of the truck, touching her shoulder. She slid over to the middle seat, leaning her head onto his shoulder, and he wrapped his arm around her body. They got up to their apartment door, Casey started unlocking it, Sylvie's hand wrapped around his bicep. They entered the dim apartment, Casey pulled her into his arms, bringing her face to his. He kissed her deeply, pushing her back against the closed door. Her hands slid down his chest, pulling up on the hem of his shirt, she helped him take it off. Putting his hands on her thighs, he pulled her up into his arms, her legs wrapped around his torso, and he carried her to his bedroom.

Sylvie stretched awake as morning light filtered through the widow. Sitting up, she saw Casey was already gone from his bed. She pulled on one of his shirts, walking out to the kitchen where he sat in just a pair of sweatpants drinking his coffee and looking at some drafts. He turned when he heard her, smiling and saying "Good morning, beautiful."

She rolled her eyes, motioning to her wild hair and smudged make up. "Oh yeah, so sexy."

He laughed, but he still thought she looked beautiful. Her messy hair, standing there in his t shirt, her bare legs begging to be caressed. He grabbed her hand, pulling her into his lap for a kiss, Sylvie ran her hands down his bare chest. Casey glanced at the clock, scooping her up and carrying her back to the bedroom. They had some extra time...

Chief Boden was pacing outside Casey's office. It was unlikely for him to be late, he was usually early to shift. Glancing at his watch again, he was starting to get worried, when he saw Casey jogging down the hallway.

"Sorry Chief, got caught up in traffic."

"Huh. Okay, well, I want to go over some paperwork with you." Casey followed Boden to his office.

Meanwhile, Sylvie slipped into the break room, grabbing a bagel for breakfast, sitting quietly next to Mouch. Suddenly, she felt fingernails digging into her arm as someone pulled her up.

"Supply closet, NOW," Stella hissed, dragging Sylvie down the hall. She thrust her in the door, where Foster was waiting with a confused expression.

"Why are you kidnapping us to the supply closet?" Foster questioned.

"YOU know why," Stella said, pointing at Sylvie. "Spill all the details."

"Guys, I don't think -"

"We had a deal!" Stella exclaimed. "C'mon, you've been leaving Foster in the dark. Tell us all the juicy details!"

"What juicy details are we learning?" Foster questioned.

"About Brett and Casey's love affair."

Foster perked up. "Oh, now I'm definitely interested."

Sylvie sighed, "Guys, there's not much to tell."

"Except that you slept with him at least once!" Stella exclaimed.

Emily's mouth fell open. "Holy shit. You have been holding out on us!"

Sylvie's face was turning red. "Maybe it was a few times."

Foster and Kidd broke out into excited rambling, asking a billion questions, Sylvie trying to shush them. "Guys, be quiet!" She pleaded, "I am so not ready for this to be public."

"Well, how was it!?" Stella asked.

Sylvie gave them a small, shy smile. "Amazing."

Her friends squealed with delight, hugging her. "Girl, you deserve to be happy," Foster affirmed, and Stella nodded her head.

"Yes. It's about time you were with a guy who's going to put you first."

"I hope so," Sylvie responded nervously as the alarm went off and they all raced to their rigs. As she climbed into the ambulance, she caught Casey's gaze, and he flashed her a grin that made her heart flutter. As they raced down the road, a thought creeped into her mind that she couldn't shake. She knew she was falling hard for him, but there were so many things that complicated their relationship. Gabby. Their shared living situation. The fact that he was technically her boss. Everything was happening so fast, and Sylvie was not one for spontaneity. Look where that had gotten her in the past. But their was something about Matt Casey that made her want more. As they arrived on the scene and she watched him race into danger, one more thought popped into her head.

She was going to get her heart broken.
