Jay was up late at night, plagued by insomnia as he often was nowadays. Restless and unable to sleep, he slipped into his athletic clothes and decided to go for a run to clear his mind. The cool night air and the familiar streets of Chicago provided a distraction from his thoughts as he ran through the city.

As Jay approached Navy Pier, he noticed something alarming - a car heading straight for the pier, seemingly out of control.

The sound of screeching tires and the sight of the out-of-control car sent panic coursing through Jay's veins. Without a moment's hesitation, he broke into a sprint towards the pier, his heart pounding in his chest.

The car slammed into the barrier surrounding the pier, the impact sending it careening into the water. Jay reached the edge of the pier just in time to see the car disappear beneath the surface of the lake.

As Jay watched the car sink beneath the lake, his mind switched into cop mode. He quickly ripped off his gloves and pulled out his phone. With a steady voice, he spoke into the phone with his badge number and full name:

"This is Detective Jay Halstead, badge number 51163. We have a vehicle submerged in Lake Michigan at Navy Pier. Requesting immediate assistance. Send police, fire, and paramedic units."

With the call placed, Jay dropped his phone into his pocket and scanned the scene, looking for any signs of movement in the lake. But the surface remained eerily still, the only disturbance being the ripples spreading outwards from where the car sank.

Jay's body hits the cold water of the lake with a splash. The shock of the cold seeps through his clothes, sending a shiver down his spine. But he ignores it, pushing forward with every stroke.

He swims deeper, his eyes straining to see through the darkness. The surface tension of the lake makes it feel like he's fighting against a thick wall, making each stroke more difficult than the last. The cold air filling his lungs each time he gasps for air only adding to the struggle.

As Jay pulls the door open, a rush of bubbles burst from the interior. He quickly reaches in and grabs the unconscious man. But as he does, he feels a sharp pain on his wrist - the woman, who he hasn't noticed before, is clinging to him, her manicured nails digging into his skin.

Startled, Jay winces at the sudden pain but doesn't let go of the unconscious man. He looks down at the woman, desperately trying to communicate with her but the bubbles and her panicked state make it difficult.

Her grip on his wrist is tight, her eyes wild with fear. He can feel the desperation in her claw-like grasp, the sharp manicured nails making it difficult to pull his arm away. He tries to reassure her, his voice soft but firm.

"It's okay, I'm here to help you. But you have to let go."

But the woman doesn't listen, her panic overriding her reasoning. She clings to Jay even tighter, her eyes fixed on him as if he's her only lifeline in this nightmare situation. He can feel his wrist starting to throb under her relentless grip.

With a firm but gentle tug, Jay finally manages to free himself from the woman's grip. His wrist is red and sore where she had been holding on, but he doesn't have time to dwell on it right now.

Pulling the unconscious man with him, he pushes against the water's resistance and swims back up to the surface, gasping for air as he reaches the top.

But the woman doesn't listen, her panic overriding her reasoning. She clings to Jay even tighter, her eyes fixed on him as if he's her only lifeline in this nightmare situation. He can feel his wrist starting to throb under her relentless grip.

With a firm but gentle tug, Jay finally manages to free himself from the woman's grip. His wrist is red and sore where she had been holding on, but he doesn't have time to dwell on it right now.

Pulling the unconscious man with him, he pushes against the water's resistance and swims back up to the surface, gasping for air as he reaches the top.

With the man's limp body draped over his shoulder, Jay swims with difficulty back towards the steps of the pier. Once he reaches the steps, he heaves the man's unconscious form up onto the concrete, cursing as he continues his efforts to revive him.

Jay positions himself over the man's chest and begins performing CPR, pressing firmly on the chest with each compression. His focus is intense, his face concentrated as he works to bring the man back to consciousness.

"Come on, breathe!" Jay mutters, panting with exertion as he continues the CPR compressions. He checks the man's pulse between compressions, frustration and worry growing with each passing second.

"Damn it, wake up!" Jay can't help but curse, his voice ragged from the effort.

As he continues the CPR, Jay's mind races, wondering why this man isn't responding to his efforts. The sound of approaching sirens echoes faintly in the distance, but he doesn't stop, his focus solely on the man lying lifeless in front of him.

The ambulance door swings open, and Jay is rushed inside, shivering violently. The paramedic takes one look at him and recognizes the signs of severe hypothermia.

"We need to get you out of those wet clothes," the medic says firmly. Her voice is steady and commanding, leaving no room for argument.

Jay tries to speak, his teeth chattering from the cold. His words are coming out in a series of stutters and gasps, as his body struggles to regulate its temperature.

"I-I w-was r-running," he manages to say, "Saw the car go off the pi-pier..."

The medic nods, listening intently. She notices how pale and shivering he is and quickly helps him remove his damp clothes, replacing them with dry, warm blankets.

"And then I... j-jumped in." He continues, his voice becoming weaker as his body begins to lose its fight against the cold. "I couldn't l-let them d-drown."

The paramedic nods again, her expression one of respect and concern. She quickly sets to work, wrapping Jay in several blankets and preparing a warm IV solution to help raise his core temperature.

"You did good," she tells him, her voice gentle but firm. "But we need to get your body temperature up now, okay? Just stay with me."

As the medic works, Jay continues to shiver and shake. His body is still trying to recover from the shock of the cold water, and his mind is still trying to process what happened.

"I-I w-was j-just running," he repeats, still stumbling over his words. "J-Just r-running and t-then I s-saw the c-car go i-into the water. I h-had to d-do something... I c-couldn't let them drown."

The medic nods, encouraging him to keep talking as she starts the IV to deliver the warm fluid into his veins. "You did the right thing. Just keep talking, okay? It'll help take your mind off the cold."

The ambulance arrives at Chicago Med, and the paramedic rushes the unconscious man on a stretcher into the ER. The medics follow closely behind, explaining the man's condition to the doctors, nurses, and staff.

"Male, early thirties, unresponsive," the medic reports briskly, rattling off the details of the man's vitals. "Found submerged in the lake, probable drowning victim. CPR performed en route."

The medical team springs into action, taking the man into a trauma room and starting to assess his condition. They prepare to initiate resuscitation efforts as Jay watches from his own bed nearby, still shivering despite the warm blankets wrapped around him.

As the doctors work on the unconscious man, Jay can't help but approach, wanting to offer his assistance if possible. He moves towards the man's bed, noticing the gun in plain sight.

"I can disarm it," Jay says quietly, his voice still shaky from the hypothermia.

The doctors look at him, eyes narrowed in concern and disbelief. One of them, a female doctor with a steely expression, steps forward.

"Detective Halstead, you're still undergoing treatment for hypothermia," she says firmly. "You're in no condition to be handling a weapon."

Jay opens his mouth to protest, but the doctor cuts him off. "No arguments. A nurse is coming to check you over now. You need to rest and recover from the hypothermia before we let you go anywhere."

Jay grits his teeth, frustrated and restless. He hates being sidelined and unable to help. But his body is still shivering, and he knows the doctor is right. He reluctantly moves back to his own bed and allows the nurse to check his vitals and fuss over him.

The nurse quickly assesses his physical state. She takes his temperature, which has thankfully risen slightly, and checks his blood pressure and oxygen levels. Despite his protestations, she takes the time to make sure he's not developing any further complications from the hypothermia.

As she works, he can feel his irritation building. He wants to be doing something to help, not lying here being poked and prodded like an invalid. He grits his teeth and tries to keep his impatience in check, knowing that arguing with the nurse would be useless.

The nurse carefully pulls back the blanket and gently lifts the gown, exposing his bare chest. Her touch is light and clinical as she places the stethoscope against his skin.

"Just need to listen to your lungs and heart, Detective," she explains softly, her voice soothing. "Make sure everything's functioning properly after your ordeal."

Jay shivers slightly as the cold metal of the stethoscope touches his skin. He does his best to keep still and cooperate, knowing that resisting would only slow things down.

The nurse takes her time, listening to his breathing and his heartbeat, her expression focused and concentrated.

She moves the stethoscope slowly over his chest, pausing at different spots to listen intently. The only sound in the room aside from the occasional beeping of medical equipment is her steady, measured breaths and the soft whisper of the stethoscope against his skin.

After a few moments, she removes the stethoscope and pulls the gown back down, covering his chest. "Everything sounds good," she tells him, her voice still gentle but a hint of a smile in her eyes. "Your lungs and heart are functioning properly and your temperature is starting to rise back to normal."

Jay nods, grateful for her thoroughness but still antsy to be up and doing something. "Am I cleared to get up and go?" he asks her, hoping against hope that she might say yes.

The nurse shakes her head, her expression sympathetic but firm. "Not yet, Detective. You need to stay and rest a bit longer. Your body is still recovering from the hypothermia, and we need to monitor you a while longer to make sure no further complications arise."

Jay lets out a long, frustrated breath, but nods in understanding. He knows that fighting the nurses on this will be pointless. He slumps back into the bed, resigned to at least a few more hours of being stuck here.

The nurse excuses herself, leaving Jay alone in the room. A few moments later, Sergeant Platt enters, carrying a bag of clean clothes.

As soon as Jay sees her, he's up out of bed, his frustration getting the better of him.

"Trudy!" he exclaims, his voice sharp with exasperation.

"For Pete's sake, sit down before you fall down," Platt retorts sternly, eyeing Jay with a mixture of concern and annoyance. She crosses the room and sets the bag of clothes on the bedside table.

"You're supposed to be resting, Halstead, not running around like a crazy man," Platt continues, her hands on her hips. "And don't think I don't know why you're so antsy. I get it, but you need to take it easy and let your body recover before you do something stupid."

Jay glares at her, his frustration still bubbling just below the surface. "I'm fine," he insists, his voice strained. "And I don't need to be coddled like a child."

"Oh, get over yourself," Platt snaps back, rolling her eyes. "You're not invincible, Halstead. You fell into a freezing cold lake and nearly died of hypothermia. Now sit your stubborn self back in that bed before I call that nurse back and have you strapped down."

Jay huffs out a breath, reluctantly admitting defeat. He knows arguing with Platt is like banging his head against a wall. He slowly lowers himself back into the bed, his arms crossed over his chest defiantly.

Once Jay is settled, Platt opens the bag and begins pulling out the clothes she brought, which include a pair of jeans, a t-shirt, and some comfortable-looking sweatpants. She lays them out neatly on the bed next to him.

"Got some fresh clothes for you," she says, her voice softer now. "Figured you'd be sick of hospital gowns by now."

"Thanks," Jay says grudgingly, reaching out to touch the fabric of the clothes. The sight and feel of real clothes rather than hospital-issued gowns is oddly reassuring, a small step towards normalcy.

"Speaking of the accident," Platt goes on, her tone turning serious once again. "There wasn't any sign of a woman in the car you found. You're sure you saw someone inside?"

Jay frowns, confusion and annoyance warring for dominance in his expression. "Of course I'm sure," he snaps. "I didn't imagine it. There was a woman in the car. I saw her."

Platt raises an eyebrow at his tone but doesn't comment. "Well, we searched the car, top to bottom. No signs of a passenger. Are you certain you didn't misjudge something in the confusion?"

"I'm positive," Jay insists, rolling up his shirt sleeve to show his wrist. "She grabbed me. Right here."

He points to the red marks on his wrist from where the woman had held on tightly. The skin is still tender and slightly swollen.

Platt leans in closer to inspect the marks, her expression thoughtful. "That looks like a pretty tight grip," she says, her tone contemplative.

Jay nods, his frustration still evident in his voice. "Yeah, it was. She was scared as hell and wouldn't let go. Thought we were both going to die for a second there."

Platt studies the marks for another moment before nodding. "Okay, I believe you," she says finally. "But if she was in the car, where did she go? It's not like she would have just gotten out and vanished."

"I don't know," Jay admits, frustration and worry etched onto his face. "That's what doesn't make sense. I saw her. I felt her holding on. She was there. And then she was just... gone."

Platt crosses her arms, frowning as she thinks it through. "It could be that she was thrown out of the car when it went into the water. Or that she was already dead when it went in. Either way, we're going to have patrol cars scour the area, see if we can find any sign of her."

Jay nods, relieved that Platt believes him but still troubled by the mystery of the woman's disappearance. "Good," he mutters, his voice shaky. "I just hope we find her. I need to know what happened."

As Jay steps out of Platt's car, he's suddenly enveloped in a tight hug from Hailey. Her relief at seeing him safe and sound is palpable, and she clings to him for a moment, her head pressed against his chest.

Jay returns the embrace, feeling his own relief and comfort in her arms. But then he stiffens, pulling away and quickly stepping back. He's still on the job, still the detective who needs to get straight to business.

"What did the gun desk say?" Jay asks, his voice steady and professional. The Intelligence Unit, who had been standing nearby, moves closer to fill him in.

Voight steps forward, "We identified the owner of the gun. Thirty-two year old male named Tyler Hayes. Ran a background check on him, and it turns out he has a history of domestic violence. Multiple arrests, but no convictions."

Hailey nods, adding, "And guess who his girlfriend is?"

Jay looks at her, his expression becoming more serious. "His girlfriend?" he echoes, waiting for her to continue.

Hailey holds up a folder, flipping through pages of information on Tyler Hayes. "His girlfriend has a name: Anna Rodriguez. Early thirties, been with Hayes for two years. History of drug abuse, theft...you name it."

Jay frowns as he takes in the information. "So we've got a violent boyfriend with a gun and a drug-abusing girlfriend. Not exactly a match made in heaven."

Voight nods grudgingly in agreement. "Exactly. And Hayes has a history of possessive behavior, according to his previous girlfriends. Seems like the type to try and exert control over those close to him."

Kevin hangs up the phone and turns to the team, a serious expression on his face. "I just spoke to my contact. He says there's a security camera a few blocks from the bridge. Might have caught something on tape about what happened with the car."

Voight nods, "Alright, let's check it out. We need all the information we can get about what happened out there."

The team gathers closely around a computer, watching as Jay pulls up the security camera footage. His fingers fly over the keyboard, bringing up the necessary files and loading the video feed.

The scene on the screen is chaotic, the rain and darkness making it difficult to see clearly. But as they watch, they can make out the indistinct shape of a car careening towards the bridge.

Hailey leans forward, her eyes squinting as she tries to make out the details in the darkness. "There," she points out, jabbing a finger at the screen. "See that? That's the car."

The image becomes clearer as the car approaches the bridge, and the team can now see the horrifying struggle taking place inside. The man—identified as Tyler Hayes—forces the woman into the car and shoves her roughly inside before getting into the driver's seat and speeding off.

God," Adam mutter, his expression horrified as he takes in the scene.

Voight's expression darkens, his lips pressed together in anger. "Looks like she didn't go willingly," he comments grimly.

"No kidding," Hailey mutters, her own expression grim. "She's fighting him every step of the way. She didn't want to get in that car."

Voight's voice cuts through the horrified silence as he barks out his orders. "Okay, we need to find this girl and get to Hayes before he does something worse. Hailey, you go with Burgess. See if you can locate Anna Rodriguez. Check out her usual haunts, talk to her friends, anyone who might know where she is."

Hailey nods, already moving to grab her badge and gun. She exchanges a quick glance with Burgess, the two of them on the same wave length.

Then Voight turns to the rest of the team. "The rest of us will head to Hayes' last known address. See if we can find him there and bring him in for questioning."

Everyone nods, a grim determination settling over the group as they prepare to dive back into the case. The image of the terrified Anna Rodriguez is burned into all their minds, the clock ticking down to find her before it's too late.

Hailey's hands are tight on the wheel as she navigates the city streets, her focus trained on the road ahead. Burgess glances over at her, noting the tension in her expression.

"How's Jay doing?" Burgess asks, her voice gentle but concerned.

Hailey lets out a soft sigh, the sound heavy with worry. "He's... holding up," she says after a moment. "Physically, he's doing okay. He's got a few bumps and bruises but he'll be fine. But emotionally... he's pretty shaken up."

Burgess nods, smiling softly. "He's strong, you know that?"

"Yeah, he is," Hailey agrees firmly, her love and concern for her husband obvious in her voice. "He's always been strong. And he's stubborn as hell. But... this is different. He almost died, Burgess. I've never seen him that close to... to..."

Her voice trails off, the fear and worry that she'd felt that night crashing over her again. She takes a shaky breath and grips the wheel harder, trying to keep herself together.

Burgess nods, her expression filled with empathy. "I know," she says softly. "It's hard seeing someone you love in danger like that. But Jay's tough. He's going to get through this. And so will you."

The radio crackles to life, and Jay's voice comes through, steady and reassuring despite the circumstances.

"Babe, got your ears on?"

Hailey's heart skips a beat at the sound of her husband's voice, relief flooding through her. "I'm here," she responds, her own voice betraying a hint of emotion. "What's going on?"

"We're at Hayes' place," Jay replies, his tone all business. "No sign of him, but he definitely lived here. We're going to search the place, see if we can find any clues about where he might have taken Anna."

"Copy that," Hailey says, her mind already formulating a plan. "We're on our way. Be there in ten."

"Copy that," Jay responds before the radio goes silent. Hailey steps on the gas, the urgency of the situation pushing her to drive faster. She glances over at Burgess, who nods grimly, knowing that they're running out of time.

As they speed through the city, Hailey's mind races, trying to think of every possibility, every way they might find Anna and bring her home safely. And through it all, the image of her husband's face, wet and pale, struggling to stay afloat, never quite leaves her mind.

The team arrives at Hayes' apartment, a crumbling building in a sketchy part of town. As they enter the apartment, the stench of decay and dirt hits them like a wall.

Jay immediately moves to Hailey's side, his hand brushing against hers briefly as he begins filling her in on the details they've discovered so far. "Looks like he hasn't been back here in at least a few days," he says, his voice low. "But there's plenty of evidence of drug use and signs of violence."

Hailey nods, her gaze sweeping over the room as she takes in the surroundings. The place is a sty, with empty beer cans and takeaway containers scattered around. There are dark stains on the walls and floors, evidence of what might have been blood or other bodily fluids.

Hailey pulls out her radio, pressing the button to talk. "This is Hailey. We need a CSU team down here ASAP. And I want an APB out on Anna Rodriguez and Tyler Hayes."

The radio crackles with acknowledgement, and Hailey shoves it back into her pocket. She turns to Jay, her expression firm. "We need to find them fast," she says quietly. "God knows what Hayes is doing to that girl right now."

Jay nods grimly, his hand clenching into a fist at his side. "I know," he replies, his voice rough with anger. "But we will find them. We're not going to let him hurt her anymore."

The room is tense as the team pores over the evidence, searching for any hint of where Hayes might have taken Anna. Adam, his expression strained, suddenly speaks up, his finger pointing at a piece of paper.

"I think I found something," he says, passing the paper over to Voight.

Voight takes the paper and scans over it quickly, his expression becoming more grim as he absorbs the information. He looks up at the team, his voice firm. "Looks like an address. Could be where Hayes is hiding out."

Hailey steps forward, her entire body taut with anticipation. "What's the address?" she asks, her voice impatient.

"It's an old warehouse down by the river," Voight replies, his hand tightening around the paper. "Looks like it's been abandoned for years. That's probably where he's holed up with Anna."

The team moves quickly, the urgency in the air driving them all to move faster. They pile into their cars and race towards the location, adrenaline coursing through their veins.

Hailey and Jay are in one car, their eyes fixed on the road ahead as they speed towards the warehouse. The silence in the car is heavy, each of them lost in their own thoughts.

The team arrives at the warehouse, the crumbling building looming over them like a dark shadow. They fan out, guns drawn and their senses on high alert.

As they make their way inside, the sound of faint screams reaches their ears, sending a chill down their spines.

"This way," Hailey mutters, her eyes locking onto the source of the sound. She points down a long hallway, and the team moves silently down the corridor, their footsteps muffled on the concrete floor.

The screams grow louder and more frenzied as they approach a closed door. Light seeps through the cracks, illuminating the dim hallway in an eerie glow. Voight motions for them to hold back, his own gun raised and ready.

He steps up to the door, gesturing for the others to stand back. Pressing his ear against the door, he listens to what's happening on the other side for a moment before he slowly reaches for the doorknob.

The knob is unlocked, and Voight pushes the door open, revealing what's inside. The team gasps at the horrific sight that greets them.

The room is dimly lit, but they can make out a figure huddled in the corner. It's Anna, her body shaking and her face bruised and streaked with tears. Infront of her stands Tyler Hayes, his hand clamped over her mouth and his body tensed like coiled snake.

Jay's eyes are like ice as he moves, his body surging forward with a speed and fury that surprises even himself. He yanks Hayes away from Anna and spins him around, shoving him against the wall. As Hayes struggles and tries to push back, Jay jams his gun against Hayes' head, his eyes never leaving the man's face.

"Don't move," he snarls, his voice low and dangerous.

As Hayes freezes, the rest of the team rushes in to help Anna, moving towards where she's huddled on the ground. Burgess is the first one to reach her, her face filled with concern as she crouches in front of the girl.

"It's okay," she says gently. "We've got you. You're safe now."

Anna nods weakly, her body still trembling. Her eyes dart around the room, taking in the familiar faces of the police officers who had rescued her. And then her gaze falls on Jay, who still has his weapon pointed at Hayes. A flash of recognition crosses her features, her eyes widening slightly.

The team leads Anna towards the door, supporting her weight as she stumbles and struggles to walk. But as they pass by Jay and Hayes, she stops, her eyes locked on the man who had terrorized her for so long.

Despite the fear still coursing through her body, there's a hardness in her expression now. A raw defiance that hadn't been there before. She takes a shaky step towards Hayes, her eyes meeting his.

"You're a monster," she says, her voice rough with anger. "You tried to take everything from me. But you didn't win. You're never going to win."

Hayes sneers at her, his eyes cold and cruel. But before he can respond, Jay's voice cuts through the tension. "That's enough," he says firmly, his gun still trained on Hayes' head.

"You've done enough damage," Jay continues, his voice filled with anger and disgust. "You'll get your day in court, but for now, you're coming with us."

The door to their apartment shuts with a gentle click, the world outside disappearing as the familiar surroundings of their home envelop them.

Jay sits on the edge of the bed, his body tense and weary. Hailey stands in front of him, her hands slow and gentle as she unbuttons his suit jacket.

She continues unbuttoning his shirt, sliding it off his shoulders and folding it neatly beside him on the bed. She can feel the tension radiating off him, the stress and anger of the day still lingering in his muscles.

"Are you okay?" she asks, her hand coming up to brush back a lock of his hair. She looks at him, her eyes filled with concern.

Jay nods, but she can tell he's far from okay. The lines of his face are taut, his eyes haunted by the events of the day. He reaches out and takes her hand, holding it tightly.

"Bit of a headache…"

Hailey nods in understanding, her fingers moving to his forehead, gently massaging away some of the tension there.

"Have you taken anything for it?" she asks, her voice soft.

Jay shakes his head, leaning into her touch. "No," he admits. "I've got some over there," he gestures to a bottle of painkillers on the side table, "but I'm not sure they'll do much good."

Hailey stands up and moves over to the table, picking up the bottle and shaking out a couple of pills. She hands them to Jay, who downs them with a gulp of water.

"You need to sleep," she says firmly. "You're exhausted."

Jay nods, his eyes drooping closed for a moment. "I know," he mutters, his voice slurring a little. "But I don't know if I can…"

Hailey slides back onto the bed next to him, wrapping her arms around his shoulders.

"Just try," she coaxes, her hand rubbing soothing circles on his back. "Lay down for a bit. I'll stay here until you fall asleep."

Jay doesn't have the energy to argue, his body too weary to protest. He lets Hailey guide him down onto the bed, his head resting against the pillows. She pulls the covers over him, then snuggles down next to him, her body pressed to his.

She runs a hand through his hair, her fingers carding gently through the messy strands. She leans in and presses a kiss to his forehead, her lips lingering there for a moment, feeling the heat of his skin.

"Close your eyes," she whispers. "Just rest, okay?"

Jay nods, his eyes fluttering shut, his body starting to relax. Hailey continues to stroke his hair, her touch light and soothing. Within minutes, he's asleep, his breathing deep and even.

Hailey pulls out her phone and opens the group chat with the CPD unit, typing out a quick message.

"Just wanted to let you know, Jay's crashed. He's got a nasty headache but otherwise he's okay. I'll keep you updated."

She sends the message, watching as the "message sent" notification pops up on her screen. She puts her phone down on the bedside table, her gaze returning to Jay's sleeping form. He looks peaceful now, all the lines of tension smoothed out on his face.

Hailey snuggles back down into the bed, pulling the covers up to her chin. She knows she should sleep as well, but her mind is still too wound up from the day to rest yet. Instead, she just watches Jay, making sure his breath continues to come slowly and evenly.

She watches the steady rise and fall of his chest, the soothing rhythm of his breathing slowly lulling her into a state of calm. Finally, her eyelids begin to droop, her body finally succumbing to the exhaustion she's fought against all day.
