Chapter Five

Kelly looked down the hallway in the direction Casey had just gone, blowing out a sigh as he turned back towards Antonio. The detective hadn't said a word since Matt walked away, surely taking a minute to process everything that had just happened. Voight tapped Antonio on the shoulder, nodding him to the exit, figuring it was best to leave.

"Sorry we had to do this." Voight apologized towards Boden, Chief giving him a nod of acceptance.

"It's okay, just keep me in the loop." Boden spoke lowly, Voight giving him a nod of his own before the two cops disappeared through the double doors.

Boden took the few steps to the entrance of the common room, seeing the men and women of 51 still in slight shock from the events that had transpired in front of them. It had been a long time since Dawson was a topic of conversation in the house, and the circumstances surrounding her surely left them all confused. Hell, Boden was confused as well. When he got the call from Voight, it was hard to hide his surprise. He wasn't given any insight as to why they wanted to come and ask about Gabby, just that they needed to talk to Casey about her. They didn't give him any more information than that, but Boden was a smart man. Something was going on with Dawson, and he was sure Casey knew that as well.

As Boden took steps into the common room, Kelly quickly walked towards Naomi, who hadn't moved from her position against the wall.

"So, Gabby... That's her, right? The ex-wife." Naomi asked him before he could even get to her. "And that cop, he's her brother? I should've known it was something like that, from how he acted seeing me at Matt's place last week." She rambled, Kelly glancing back towards the common room, seeing everyone looking at the two of them.

"Naomi, you should go. It's not a good time for you to be here right now." Kelly told her, ignoring what she had just said.

"But she's the one who left him, right? Why is her brother so mad at Matt?" She pried, also choosing to ignore what Severide had told her.

"It's complicated. Way more complicated than I could even begin to explain, and if Matt wants to tell you, he will." Kelly told her, seeing a satisfied nod come from her. In reality, Kelly knew Matt probably would never tell her about Gabby, but he wasn't about to tell that to Naomi, not when he needed her to leave. "Matt will reach out when he's ready, but really, it's not a good time…" Kelly tried again, leading her towards the exit. Huffing out a frustrated breath, she nodded, giving Kelly a hard look before walking out the doors.

Severide brought his hands up to cover his face, pressing harshly against his eyes as he let out a soft groan. He turned back towards the common room, seeing everyone sitting in their quietly, Boden standing in the middle of the room with his arms crossed over his chest. Knowing he was being waited on, Kelly entered, giving an apologetic nod towards Chief as he leaned his body against the wall.

"I know you all probably have a lot of questions, and are curious about everything that just happened-" Boden started, the eager ears of 51 listening to his every word. "But right now, I just need to know if any of you have heard from Dawson recently." He asked, glancing around the room.

No one made any move, everyone glancing at someone else to see if anyone had in fact spoken to her.

"No one has, at all?" Boden asked, looking around again. Some members of 51 had their eyes on the ground, others looking around, waiting to see if anyone was going to speak up. "Brett?" Boden asked with a slight hopefulness in his voice, but the blonde paramedic shook her head.

"Okay, well-" Boden started, clearing his throat, "if any of you hear from her, you need to tell me. Or Antonio, Voight. Someone." He finished, catching the concerned and worried gazes from the firehouse.

"What's going on, Chief?" Cruz's voice broke through the silence, concern laced in his words. But Boden merely shrugged, his hand rubbing over his mouth.

"I don't know, all I know is if you hear from her, Antonio needs to know." Boden spoke sternly, members of 51 nodding in understanding. A few members of 51 went back to what they were doing before Casey and Antonio had their fight, but most of them were seemingly stuck in place, all trying to figure out the same thing.

"So no one's heard from her?" Herrmann finally asked after a few painful moments of silence.

"Not since she left." Brett mused, a few others nodding in agreement.

"I hope the kid's alright." Herrmann muttered.

"Did anyone try and call her?" Severide wanted to know, seeing heads snap up at the sound of his voice. A few guilty looks spread across the faces of 51, while others kept their gaze focused solely on the ground. The reactions from his question were enough to give him an answer.

Pushing himself from the wall, Kelly starting walking from the common room. He needed to talk to Matt, he needed to know what all was said in Boden's office.

"Did you call her, Severide?" Otis asked, stopping Kelly as he was almost in the hallway. Turning back to face them, he shook his head softly.

"No, but I should have…" He regretfully spoke, turning away from them to walk down the hallway, his next words coming out barely above a whisper. "We all should have."

Casey paced the confines of his office, ignoring the stinging pain in his hand as the events of the past hour crowded his mind. A million thoughts were hitting him at once, and he didn't know which to follow.

He knows he shouldn't have punched Antonio, he should not have done that. But he couldn't help it. Hearing those words come from Antonio's mouth, and how he clearly believed them, it infuriated Matt. Antonio had been there since the beginning, he saw more than most about his and Gabby's relationship, he had no right to claim that Matt never loved her. That he never cared about her, because it simply wasn't true.

The regret he was feeling about punching Antonio was nothing compared to the worry and concern that was flooding his body. Emotions were overwhelming him as he thought over all the possibilities of why Antonio needed to know if he'd heard from Gabby, and none of them were good.

Gabby had just spoken to him, barely a week ago he had heard her voice, what could've possibly happened to her in that time?

Matt blew out a sigh of frustration as he continued pacing, his mind always going back to Gabby. If she had kept calling him, certainly she would've been calling her brother. It made no sense for her to call him, but not Antonio. Matt knew how much Gabby and Antonio kept in touch, at least they were when he and Gabby were still speaking, and he couldn't see any reason as to why they wouldn't still be now. He couldn't understand why she'd reach out to him, but not Antonio, when Antonio was clearly worried about her.

As his pacing continued, his eyes caught the photo of her sitting on his desk. It caused him to slow down his steps, as he stared at it, taking in the features he knew by heart. He walked up to his desk, picking up the photo to examine it closer. His fingertips traced over her face as he held the frame tightly in his grasp.

He just wished she was here now. That whatever was going, whatever had Antonio so worried, could all be easily explained and that she was fine. That none of them had any reason to be concerned for her.

But she wasn't here. And Antonio did have some reason to be worried, Matt just didn't know what it was.

Sitting down at his desk, Casey put the picture back in its place, pulling his phone from his pocket. He needed to call her. He needed to hear her voice again, and have her explain to him what was happening. To ease his fears, to hear her tell him that Antonio had no reason to be worried. He needed that. He needed her.

He'd be lying to himself if he said he hadn't been waiting to hear from her again. After their last phone call, he found himself needing to hear her voice. He wanted to call her, so many times he almost did, but he didn't want to push her. He knew he was the one to end their contact, he didn't want to force her to talk to him if she didn't want to. But that didn't mean he wasn't hoping she'd call him again. That he kept his phone near him all the time, that every time it rang he felt a smile fall onto his face at the thought of talking to her again, just to have it fall in disappointment every time he saw it wasn't her.

Fumbling with his phone in his hands, he quickly dialed her number, putting the phone up to his ear as fast as possible. He frowned as it went straight to voicemail, but that frown was replaced with a small smile as he heard her recorded message. It wasn't what he wanted, but at least he was hearing her voice.

As the tone beeped, Matt spoke softly, "Gabby, hey, it's me. Please call me when you get this, alright? I really need to talk to you."

Sighing, he hung up and called again, feeling more defeated each time he'd call only for it to go straight to voicemail.

Going over to his recent calls, he found the number she'd been contacting him on. He wasn't sure where this number went, where she had been calling him from, but he could only hope she would answer.

He felt a sliver of hope as the phone actually rang, but he was quickly met with the voicemail again. It wasn't her this time, just the automated droning telling him to leave a message. He had no way of knowing if this would ever get back to her, but he had to try.

After leaving her a voicemail similar to the first, he angrily slammed his phone down against his desk. With each moment that passed, he felt his stomach sink a little further, feeling nausea creep up inside him as he thought over what could possibly be going on with her.

He knows he needs to tell Antonio about the call he got from her, the calls he had been getting from her. Antonio needed to know, for whatever reason. He just didn't know how to make sense of it all.

It had been almost two weeks since the first time she tried to call him, since that night she first reached out, when Naomi had answered his phone; the thought made him sick. The thought of Gabby calling their home phone and finding another woman on the other end. He knows he had every right to move on, she's the one who left him, but he can only imagine what Gabby must have been feeling when she heard Naomi answer the phone. What went running through her mind when she realized he'd had a woman in the home that they shared. While he technically knows he did nothing wrong, it doesn't make him feel any better, knowing that he hurt her without even getting the chance to speak to her.

Matt snapped out of his headspace as he heard his office door open, Kelly stepping inside without even bothering to knock. Severide saw the look of confusion and hurt covering his face as Matt looked up at him, and Kelly couldn't help but hurt for his friend. For both of his friends.

"You okay?" Severide asked cautiously, Matt opening his mouth to speak but then just closing it, not knowing how to respond. "They came to talk to you about Dawson, didn't they?" He asked, but the tone in his voice told Matt he already knew the answer.

"They wanted to know if I'd spoken to her, if I've heard from her at all." Casey found his voice, the usually self-assured Captain sounding lost.

"Have you?" Kelly asked after a beat of silence. Matt's eyes flickered down towards the ground, as he took a deep breath.

"I have." Matt whispered, Kelly's eyes widening.

"I thought you said you hadn't spoken to her since-"

"I hadn't." Matt cut him off, looking back up at Severide. "When you asked me, I hadn't heard from her. But a week ago, I talked to her." Kelly leaned back against the frame of the door, taking a second to gather his thoughts before speaking up again.

"How is she?"

"I-" Matt stuttered, not sure how to answer, "I thought she was okay, she sounded alright. But now, all this stuff with Antonio, I don't know…" Casey trailed off, covering his face with his hands.

"What did Antonio say?"

"... I didn't tell him." Matt spoke sheepishly, Kelly in disbelief.

"Casey…"

"I know, I know." Matt said, frustration evident in his voice. "I messed up, I should've told him."

"Why didn't you?"

"Because he stormed in here, demanding to know if I'd heard from her but he wouldn't tell me why. All he said is that it wasn't my place to know anymore, he wouldn't even tell me if she was alright!" Anger was building inside Casey once again as Antonio's words came back to the forefront of his mind.

"Casey, I don't care what he said, you have to tell him, he's been freaking out and-" Kelly stopped himself as he saw the look that covered Matt's face, the anger now mixing with confusion.

"What are you talking about?" Matt asked apprehensively, standing up from his desk. Huffing out a breath, Kelly met Matt's narrowed gaze.

"Antonio called me, the shift where you cleaned out Gabby's locker. He asked if I'd heard from her, if anyone had heard from her." Matt stood emotionless as Kelly spoke. "He sounded freaked, like something was wrong." Kelly watched as Matt tensed from his words, Kelly taking a deep breath before continuing. "He refused to say much, in fact he pretty much hung up on me. I went to speak to him a few days later, to try and figure out what was happening, but he wouldn't tell me anything. I told him to at least tell you what was happening, that you needed to know. I'm guessing he never did." Kelly finished, watching as mixed emotions played out over Casey's face, clearly trying to understand what all he'd just heard. Nearly a minute of silence passed before Matt spoke up.

"He did, or he tried to I guess… He came to my place, said he needed to talk to me about something important."

"What happened?" Kelly pressed.

"Naomi was there…" Matt spoke, almost wincing from the thought of that day. Kelly gave a slight nod in understanding, realizing more of what Antonio had been talking about during his and Matt's fight in the hallway.

"He, uh, stormed off after that. I tried to stop him, to get him to tell me what he was there for, but he wouldn't. He was pissed, and I get it. I do, I just- god how did this all get so fucked up?" Matt said angrily, collapsing back down into his chair, his head falling down into his hands. Kelly watched his friend closely, seeing him starting to crumble. He walked the few short steps to the desk, placing his hand supportively on Matt's shoulder.

"I need to know what's going on…" Casey muttered, Kelly barely able to hear him.

"You need to go talk to Antonio, man." Kelly spoke, Matt nodding slowly as he lifted his head to meet Severide's gaze.

"I know, I just-"

"Now, Matt. You need to go talk to him now." Severide spoke firmly, removing his hand from Matt as he took a step back. "Something's going on with Dawson, you know that." He paused, seeing Casey's already rigid form tense more. "Whatever it is, she's gonna need you." Kelly took a breath, seeing a look of panic clouding his features. "But right now, Antonio needs your help. You need to go talk to him." Blinking back the few tears welling in his eyes, Casey nodded.

"Okay." He agreed, pushing himself up from his chair.

"I'll talk to Boden, you go to 21." Kelly instructed, both men leaving the office, Kelly heading towards Boden, Matt heading towards the locker room. "But Matt," He called, stopping the Captain, "don't punch him this time." Matt gave little reaction as he made his way to the locker room, Kelly making his way to the Chief's office. His path was stopped when he saw Boden still in the common room with everyone else, low chatter surrounding the group.

"Chief." Kelly called from the entrance of the common room, stopping the conversation he was currently having with Herrmann. Boden raised his eyebrow as he turned to face Severide, Kelly taking a few steps into the room as he felt everyone's eyes on him.

"Casey left to go talk to Antonio." Kelly saw Boden tense at his words, "he's not going to fight him Chief, he's really going just to talk." Severide tried to ease his worries.

"About Dawson." Chief said, not as a question but rather a statement. Kelly nodded slowly, Chief resting his hands on his hips as he sighed.

There was an unsettling silence that fell over the room, no one willing to voice the questions they had, not until Brett spoke up.

"Is Gabby okay?"

Kelly felt the expectant eyes of 51 turn to him for answers, each of them wearing a similar face of worry. Locking eyes with Brett, he finally spoke.

"I don't know."

It took all of a minute for Matt to collect his keys and his wallet before jogging out towards his truck, fumbling with the lock for a moment until he was able to get in. His engine roared to life as he took a slow, deep breath. He needed to calm down. His emotions were running high, but he knew he needed to be level headed when talking to Antonio or he'd get nowhere.

Pulling his phone from his jacket pocket, he frowned when he saw he had no missed messages. Not able to stop himself, he called the number again, his frown deepening when it went straight to voicemail this time. Words started fumbling from his mouth before he could even process them, let alone stop them. "Gabby? It's me, Matt. I really-" He drew in a breath of air, cutting himself off as he tried to keep his emotions in check, "I really need to hear from you, I just- god, baby, I need to know that you're okay." His words came out in a whisper, his voice breaking as he spoke. "Please call me if you get this… Please." He pleaded, the phone cutting him off before he could say more. He tossed his phone onto the bench seat of his truck in frustration, pulling out of his parking spot quickly.

He couldn't shake the terrible thoughts crowding his mind during his drive to the district. More than anything, he hoped this was all some misunderstanding. That Antonio was worried for nothing, that Gabby was fine. But Matt knew how unlikely that scenario was, which lead to the much more horrifying ones to plague his mind.

He needed to know what was happening.

Before he knew it, he found himself at the 21st, parking in the first spot he could find. He tore his keys from the ignition, grabbing his cell phone before practically throwing himself from the truck. As he locked it, for the first time he noticed his hands were shaking.

Forcing himself to calm down, he jogged down the sidewalk to the entrance of the district, taking the steps two at a time as he made his way inside. His eyes moved around the lobby, seeing policemen buzzing around him. His eyes landed on a familiar face, Matt's long stride getting him to her desk quickly.

"Captain?" Casey heard the surprise in Platt's voice at seeing him arrive at the district, the cop knowing he should be on shift right now. "What can I do for you?" Trudy asked, tearing her eyes away from her computer screen as she took him in. He gave her a polite smile, eyeing the stairs up to Intelligence.

"I need to see Antonio, is he here?" Casey asked, shoving his trembling hands into his pockets.

"Should be, let me call up there- oh hey, Halstead." Platt called, Matt turning around as he saw Halstead and Upton walking in. "Dawson upstairs?" Jay eyed Casey, his gaze flickering back to Platt as he nodded.

"Should be."

"The Captain needs to see him."

"We'll take him up." Halstead agreed, Matt walking over towards the partners, giving them a slight head nod. "How you been, Casey?" Jay asked as they started the climb, Upton unlocking the door to get upstairs, Matt following the two detectives as they walked through it.

"Alright." Matt mumbled.

"Is Antonio expecting you?" Hailey asked him as they walked. Although she didn't know much of the situation, she did know Casey had been married to Antonio's sister before she left town. While she'd only met the woman in passing, she knew how much Gabby meant to Antonio, how much she surely meant to the man behind her.

"Uh, no. He's not."

The three of them got to the top of the steps, Matt noticing instantly that Antonio wasn't at his desk. Looking around, he saw Ruzek and Burgess at theirs, both of them giving him small smiles when they noticed his presence. It was unusual for Casey to stop by, considering his long history with Voight, and now the more recent history with Antonio, so no one really knew what to make of him being here.

"Looks like he's talking to Sarge." Jay spoke, breaking away from them and heading towards his own desk. Matt gave a nod, signaling he heard what Jay said, but didn't give much else as a response. He stood there at the top of the staircase, looking into the closed office door, seeing the two men deep in conversation.

"You can sit down if you want, it might be awhile." Burgess offered, Matt's gaze snapping from the office towards Kim. The entire Intelligence Unit knew her words to be true. It wasn't uncommon over the past week for Antonio and Voight to be locked up in his office, in fact it was more uncommon if they weren't. No one else on the team knew what had them working so hard, and so secretly, but they knew whatever it was had been causing the younger detective stress. Not a day had gone by where Antonio came into work looking anything other than worn out and worried. And when Voight and Antonio returned this afternoon, the latter sporting a busted lip, the team had even more cause for concern.

"I'm good." Casey gave shortly, clenching his hands in his pockets, willing the slight tremor that was still present to go away.

"Casey…" Only moments had passed until Matt heard Antonio's voice say his name, obviously not expecting to see him there.

"We need to talk."

Antonio wasn't sure what to make of the lack of emotion in Casey's voice, and he had no idea what to expect from him. He knew Matt was angry, but judging by the look in his eye, he was more concerned than anything. With a small nod, Antonio gestured towards the break room.

"We can talk in here." Antonio headed in first, Matt noticing Voight follow in after him as Casey walked through the bullpen, ignoring the glances from everyone else. He had no idea if the rest of the team knew of Antonio's worries about Gabby, but based on their confused reactions to his presence, he was guessing they didn't.

When Matt walked into the room, he immediately shut the door behind him, staying close to the wall as he met Antonio's gaze. The looks of anger that both men had held onto so strongly nearly an hour ago were long gone.

Pulling his hands from his jacket pocket, Matt crossed his arms over his chest, glancing to Voight as the man leaned against the counter, but he forced himself to focus back on Antonio. He was the person Matt needed answers from.

"I need to know what's going on with Gabby." Casey spoke firmly, his stance strong. If Antonio was surprised at this being the reason for Matt's visit, he didn't show it. Matt watched as Antonio glanced to Voight, and before the detective even spoke Matt knew Antonio didn't want to give him any answers.

"Casey-"

"You keep saying it's not my place to know, but that's not true and you know it." Matt cut him off, surprising himself by the strength of his words. "By the way you've been acting, I know something's wrong. What happened to her?"

"Matt, listen-"

"I talked to Gabby."

Matt's admission caused Antonio's spine to straighten, stunning the room into silence, Voight instinctively leaning forward as the words resonated. Once the initial shock wore off, Antonio took a step forward towards Casey, his eyes narrowing.

"You talked to her?" He asked for clarification, even though he heard the words loud and clear. Matt nodded slowly in response. "When?"

"About a week ago, last Tuesday night."

"The night I came to see you, you had spoken to her?"

"It was after you left, maybe an hour later? I don't know. But she called me." Casey was surprised to see just how relieved Antonio was to find out he'd heard from her, which only made Matt's stress levels spike.

Antonio's hands came to rub over his face, blowing out a slow shaky breath, Matt watching as Voight came over and patted him on the shoulder, almost as if for reassurance.

"Dammit Casey, why didn't you tell me at the firehouse?" Antonio asked. Even though Matt was expecting there to be anger laced in his words, there wasn't any; the relief seemed to be outweighing everything else.

"I know I should have," Matt started honestly, "but I also knew if I had, I would never know what's going on. I need to know, Antonio." His voice started wavering towards the end of his sentence, the detective noticing immediately. He wasn't able to hide the emotion in his voice this time. "Something's wrong with her, isn't it?" The shakiness in his words only increased, Antonio frowning softly as he listened to Casey.

No matter what Antonio thought about him, Antonio knew Matt was worried. He noticed how the firefighter's body had been trembling, the look of fear that would flash in his eyes every so often, the man unable to stop it. Hearing the concern in the man's voice only confirmed what Casey's body language already told him. Matt was terrified. Terrified of something being wrong with Gabby, scared that something bad had happened to her. Despite whatever fronts Casey had been putting up before, for the first time in a long time Antonio had no doubt in his mind that Matt was still in love with his sister.

"Antonio, please…" Matt pleaded when he hadn't responded.

Eyeing the desperate man in front of him one more time, Antonio nodded towards the table as he walked closer to it, taking a seat. Reluctantly Matt followed, taking a seat in the chair beside him. Antonio took a deep breath, glancing back to Voight who gave him a slight nod.

"We thought she was missing, Casey."

I can't wait to hear what you all think. Answers as to what's going on with Gabby are coming in the next few chapters. And the next few chapters are actually the idea in my head that started this story, so I'm really excited for those.

Hope you all liked this chapter, thanks for reading!
