Chapter 15

"Casey's dead, your turn!" Spellman bellowed as if the unconscious Kelly could hear him...The ex-firefighter delivered one final kick in Severide's ribs and rushed in the direction of the master bedroom. Through his own and Logan's violent wheezing, he could hear the child's cries…he was a monster, but no, he could not let a kid die in such a painful way…he was too young, too innocent, just like his daughters. No…killing members of the firehouse that had ruined his life was one thing, but not Logan, no matter what Hadley had ordered him to do.

"It's okay…it's gonna be okay." Spellman whispered, Logan's wide, petrified eyes staring at him, begging him for mercy. The ex-firefighter was feeling the effect of the chlorine gas on his body, but he ignored the burning sensation in his eyes, knelt on the floor and untied Logan's small wrists, grabbing the child in his arms, using one hand to rub circles around his back. Logan pressed his eyes shut, not sure if the man was gonna save him, or let him die next to the fireman lying already half dead on the floor in the living room.

"Over there!" Lindsay slammed on the brakes, nearly getting hit by the car behind them. She ignored all the swearing coming from the other driver and pointed Kelly's car, Halstead's eyes moving from his partner, to the vehicle and back. After her visit at Matt's apartment and Boden's call, she had placed a GPS tracker on the underside of the Camaro, realizing thirty minutes later that it hadn't been configured properly. It had taken Mouse nearly an hour to fix it, but he had finally called the Detective to let her know that the car had moved to an address that meant nothing to her.

"Look." Jay's index finger pointed one of the windows of the apartment building on the street, thick yellowish smoke escaping through the small openings on the side. Before Lindsay could open her mouth, the fire alarm sounded, followed by a mother and two children bursting through the fire escape.

Instinctively, Erin placed her hand on her gun, making sure it was there and opened door, Halsted reaching out to stop her.

"Jay…"

"We gotta wait for back-up!"

"You stay here!" Lindsay growled, the stern expression on her face telling her partner she would not listen. "Call 911, get Voight here!"

Xxx

"No no no." Spellman mumbled when the fire alarm sounded in the whole building, footsteps coming from the floors above and below him. He peered through the window in the hallway, cursing when his eyes fell on Halstead, who was already guiding people out.

"Sir, you okay?" A middle-aged woman asked in concern, having just left her apartment and stumbled across a man looking too desperate and angry…With the corner of her eyes she could see Logan gasp for breath.

"Sir, you need to get out, now!"

Spellman shot her a glance, an idea striking him. "Take him." He murmured, turning around so she could take Logan from his arms. She hesitated for a few seconds, but grabbed the child, Logan wrapping his arms around her neck. "Go." Spellman instructed and she headed down the stairs. He waited for a few seconds before putting the hood of his sweatshirt up and following a family of four in the same direction…

He made it to the first floor's staircase when he caught a glimpse of Erin talking to a frightened woman between the ground and the first floor. Just after Lindsay instructed the single mother to run outside and wait for the fire department, Spellman sneaked behind the Detective and used one elbow to deliver a punch behind her temple, knocking her down…

"Clarke, take Capp and check the apartment! Tony, Mills, start from the top floor. Truck, vent the roof and do the prim - " Boden was cut off by an explosion on the third floor, clouds of smoke escaping through the broken windows.

"You smell that?" Jeff Clarke looked at Chief and then at Truck 81's temporary Lieutenant.

"Chlorine." Lieutenant Mitchel stated, masking up.

"GO!" Boden's voice boomed. He turned to look at two CPD officers standing behind him. "Clear the area!" But just when his men rushed inside the building, Scott yelled for a paramedic and ran in the direction of a woman…a woman carrying the motionless frame of Logan…

"Detective Lindsay's down!" Mills radioed a long minute later, the tension building further, especially for her team now standing next to Boden and staring at the chaos their arsonist had created. "She has pulse, Chief! We're coming out now!" Peter added and Voight stepped closer to the exit, instructing his team to start looking for any trace of Spellman or Hadley.

"Door's locked." Clarke shouted, stepping aside so Capp could pry it open. "We're in!"

"Severide!" The Squad members yelled, then once more, but no reply came.

"Do we have a vent?" Another voice sounded through the radio.

"Negative!"

"Top floor's clear!" Cruz yelled.

"Roof's gonna collapse!" Otis shouted not able to mask the agitation in his voice.

"Watch out!" Someone shouted.

"Cruz!" Otis yelled again, horrified. "Chief, the stairs are gone. We're trapped!"

"Move that ladder!" Boden barked to whoever was outside with him. "I'm coming!"

Jeff crouched and moved forward through the tick poisonous smoke, his gloved hands landing on random objects in the living room, Capp doing the same but going in the opposite direction…everything was happening too fast…the fire spreading too quickly.

"Severide!" Capp yelled when he finally stumbled across the body of his friend.

"Crap!" Clarke jumped on Kelly's legs, fighting the flames eating his jeans and skin, Capp checking for a pulse, desperation on his face. He let out the breath he had been holding when Jeff cut off the oxygen fuelling the flames. "C'mon buddy!"

"Chief, we're coming out now!" Capp grabbed Kelly under the armpits, Clarke carefully holding his legs and leading the way out.

They had barely made it out of the apartment when Capp felt Kelly's unconscious frame convulse, Severide trying to twist his torso, carrying him out getting twice as hard. They didn't have time to stop…just two more floors down. "C'mon Severide!"

"He's gonna throw up!" The moment Clarke gave the warning, Kelly twisted the upper part of his body, his mouth opening.

Capp acted instinctively and used one hand to turn Kelly's head around, trusting Clarke to support Severide's weight, so that Kelly would not choke when the content of his stomach flew out of his mouth.

Chief was listening to his men's every word. He moved closer to the exit, meeting them at the bottom on the stairwell to help the two Squad members place Kelly on the awaiting gurney. He could not do anything else…Boden joined the rest of the men watching helplessly as the two paramedics struggled to stabilize Squad's Lieutenant…it was hard to focus, for all of them. They could hear the paramedics mention obstructed upper airways, bronchospasm, their failed attempt to intubate…and the second successful one. When the ambulance took off, Jeff locked eyes with Boden, as if to remind him of the deal they had – Clarke had agreed to be a temporary Lieutenant, keep Kelly's job safe for whenever he was ready to return…he was going to make it…he had to…right?

The last thing Casey saw before a massive piece of the ceiling collapsed on the camera videotaping the events in the building he had used to call home was Capp and Clarke pulling Kelly's lifeless body away…When it all went blank, Matt pressed his eyes shut, getting closer to losing his own strength and willpower…his mind couldn't process all of it, he just couldn't believe it…Kelly couldn't be dead, not his friend, not the indestructible Kelly Severide…Casey was thirsty, but he wasn't going to beg for water…yet. The strong smell of chlorine and the brake fluid on his skin were making him sick, Hadley sensing how weak his pray was.

"Game over." The corners of Kevin's mouth twisted in a sick smile. "I wanted my face to be the last thing Severide sees, but I can't have it all, right?"

"He's…not…" Matt's voice trailed off, talking hurting his sore throat too much, making breathing extremely hard.

"If not yet, he'll be soon…You saw him, Lieutenant, you can imagine the concentration of that chlorine gas in the unventilated room, he was lying there for what…five-ten minutes? His body was on fire, the blow to the head. You know him, you know he blames himself for everything, and it's his fault… you think he's even gonna fight?"

Matt listened carefully to every word of Hadley's speech…and his heart tightened. What if his friend just gave up, escaped their word, followed Shay? Did Kelly even have a reason to fight anymore?

"Don't worry, you're next." Kevin shrugged his shoulders innocently, the evil grin spreading across his face. He squeezed the water bottle he was holding and poured some of the liquid into his mouth, looking down at Casey's figure.

"I think - " Matt coughed, taking a few seconds to catch his breath, then swallowed before looking at Hadley again. "that Spellman…ruined your…plan. Don't think…they'll let him…get…away now."

"A damn traitor!" The expression on Kevin's face suddenly changed, betraying his anger and disappointment. "But he served his purpose well…now I gotta make sure he keeps his mouth shut…he's gonna suffer."

An hour had passed before the rest of Fifty-one made their way to the emergency room, Boden leaving other firehouses in charge to putt off the fire and deal with the poisonous gas.

"She lost consciousness so I want to keep her overnight, as a precaution, but I believe she is going to be just fine." The firemen walked into the waiting area just as a female doctor updated Voight on Erin's condition. The detectives around relaxed, Jay leaning on the back of the chair, Antonio smiling at his little sister who had joined them ten minutes earlier. Otis and Cruz were sitting next to each other, Joe having been transported to Chicago Med after the stairwell collapse, but he was fine.

"What about my men?" Chief barked from behind the Doctor, startling her. She turned around, staring at him in confusion.

"Sir, I'm sure someone is going to update you soon. Why don't you sit – "

"I can't wait!" Boden snapped, the Doctor not intimidated at all. Voight made a step forward, resting his palm on Chief's shoulder and looking at her apologetically.

"Lieutenant Kelly Severide and Logan Rice…victims of two monsters." Hank spoke, clenching his fist tight at the thought of Spellman escaping from the building, unharmed.

The doctor sighed, taking another look at the people there…covered in dust, sweaty, they were all one family, serving to protect the city, a family she and all the hospital personnel belonged to. "I'll see what I can do. But you need to sit down and let us to do our job."

Boden nodded, collapsing on the nearest available chair.

Hank turned to look at his team. "We've got a fireman to find and justice to serve!" He kept his hoarse voice low, out of respect for the people in the waiting area. "I'm gonna check on Lindsay and meet you at the District!"

Xxx

Twenty-five long minutes went by with no update on Kelly's condition or Logan before Voight returned into the waiting room, informing Boden that Lindsay had wanted to leave, but had agreed to stay after hearing everything about Severide. Hank asked Chief to look after his girl and left, to serve justice, his type of justice.

Another ten minutes later Herrmann rushed into the room, terrified, fixing his eyes on Boden. "Any news?"

Chief grimaced, the answer going without saying. He wasn't sure if his friend was asking about Severide, or Casey, or both, but it was a "no". Otis buried his face in his hands, leaning forward, Mills pressing his eyes shut, Capp and Clarke remaining silent and motionless.

"Saw Rice in the pediatrics ward." Christopher spoke with a hint of hope in his voice. "Said Logan's scared, but he's gonna be fine. The chlorine didn't do any damage…apparently Spellman's been taking good care of him." He snorted, biting his lips to stop himself from saying how ironic it was that the same ex-fireman had allowed for Luke to get injured, but had suddenly decided to not harm another kid. He was grateful to God Luke was awake and responsive, the rest of his family living in Mouche's house, but Christopher could never forget what those monsters had done to Luke.

"Good." Brett uttered, nobody daring to say another word.

They sat in silence for another twenty minutes, Boden using five of them to call Benny Severide, until a different doctor appeared, asking for family of Kelly Severide.

"Leslie Shay?" Doctor Andreas moved his eyes from Brett to Dawson.

"She..."

"Died last year." Herrmann finished Brett's sentence, his heart sinking, no matter it had been nearly a year.

"She's listed as Kelly Severide's next of kin."

Boden snorted, of course Kelly hadn't bothered changing his emergency contact…not that he'd had time to do it after he had finally come in terms with losing his best friend. "I'm his Chief!"

Doctor Andreas paused to look at each and every member of the family, the concern on their faces, the desperation…"He's stable for now…But his condition remains critical. He's had two mild head-traumas in the past few months and the blow to the head he's suffered now has caused an epidural hematoma. We've managed to reduce the pressure, but I can't make any prognosis yet. The chlorine gas exposure's led to a severe respiratory arrest, a perforation in the uppermost part of the oesophagus - "

"English!" Chief growled, regretting his harsh tone when Mouch shot him a glance, begging him to calm down.

"His airways are scarred and severely swollen. We've put him on a ventilator, meds to treat the bronchospasm, antibiotics, diuretics, but right now I have no idea how much his lungs are compromised. Two cracked ribs, second degree burns on his legs and first degree on his abdomen and back, but they are under control. If he survives -"

"If?" Cruz looked at the doctor in shock, voicing out everybody's fears. "He's going to pull through, right?"

"Look, these injuries are life-threatening on their own, not to mention in combination. The chances for a full recovery are about fifteen percent, forty that he'll have a relatively normal life, desk job - "

"He's a firefighter!" Lindsay's voice boomed from the entrance of the waiting room. She stepped forward, dressed in a hospital grown, a bruise where her left cheek had connected with the edge of the stairwell.

"I'm sorry…Does he have any close relatives around – parents, siblings? In case any decisions need to be made."

"His father's on his way." Mouch didn't like the question, but it was the Doctor's job to ask.

"I want to see him." Boden barked, needing to make sure his man was really alive and fighting. Because he couldn't do that for Casey…he could only prey.

"He's heavily sedated and I intend to keep him in a medically induced coma until – "

"Doc…" Herrmann uttered, blinking once in an attempt to mask the tears welling up in his eyes.

Doctor Andreas sighed, pausing for a second, and nodded.

Lindsay pushed the door of the ICU room opened, letting Boden in first, scarred of what they might see inside.

"Kelly…" She uttered, taking a few more steps in the direction of the bed, wrapping her fingers around his hand. That wasn't her Kelly…wasn't the big, strong fireman she knew…it was a man paler than a ghost, bandages wrapped around his head, a tube in his throat, a machine breathing for him, thinner tubes and lines stuck in his veins, electrodes attached to his chest…it wasn't like he was sleeping…it was as if he was dead, only the beeping of the machines and the readings displayed hinted his heart was still working, his brain was still functioning. "Why…why did you have to go alone?!" She wanted to be mad, to yell at him, but she couldn't…

Boden rested his palm on the bed, afraid he would cause Kelly more pain if he touched his burned legs. "You've still got your spot on Squad, Severide..." With the corner of his eyes he saw the Detective rest her head on Kelly's arm, her hands touching his cheek, not giving a damn if it was a sign of weakness. Chief squeezed his Lieutenant's hand, hoping to feel it moving, twitching, but it remained still as a cold stone. "The house needs you…Casey would need you…just keep fighting. Can't lose any more people."

Boden rubbed his eyes with his free hand, preparing to leave and give Erin some more time with the man she loved like no one else in her life.

"Kelly!" There was panic in her voice. Lindsay jumped on her feet, Chief turning around to see Kelly's body convulsing, alarms going off. Two nurses rushed in, one of them asking them to leave, but they could not move. Doctor Andreas ran into the room, another nurse guiding them to the door…

"Oxygen levels and heart rate are dropping!" A male nurse shouted.

"Damn it! He's going into acute respiratory distress! Lungs must be filling up with fluid - "

Xxx

"What the hell?!" Sergeant Platt could not believe her eyes when a man, whose photo was hanging on her desk, walked into her District. Burgess put the car keys she had just been given in her pocket and drew her gun, Roman and three other officers doing the same.

"He's…got my daughters." Spellman uttered, getting his hands in defensive position in front of him.

Thank you all for reading, and thanks sooo much for reviewing to those of you I cannot pm.

I promised you hurt Kelly and here it is, he's not walking away with just scratches…now would he find strength and willpower to fight? Especially if he thinks Casey's dead…and yep, hurt Matt as well, and he's about to give up…damn you Hadley! But Logan's safe, who would have guessed Spellman's not entirely heartless…

A bit more Boden in this chapter, felt as if it was time for him to step up and be there for Kelly when Casey's unable and Benny's far away. Did you like it? And some Clarke, too.

Who's looking forward to some Voight/Spellman time?

Would love to hear your opinion so please review before you go Thanks!
