Time appeared to drag on as Severide watched Casey being assessed and cleaned up. Chaos still seemed to reign around them, as crews rushed to clean the accident scene. Kelly had focused mainly on Matt, knowing that he couldn't do anything to help his team. All he knew was that some of the men from Truck 66 were in critical condition and on their way to the hospital. Which is where Matt should be headed… His mind reminded him. Looking briefly at the paramedics tending to Casey, Severide frowned when he realized they weren't packing up. The second the paramedics signaled for Severide to return to Casey's side, the squad lieutenant immediately complied, reaching to gently grasp Matt's good shoulder.

"What's going on?" he asked, scrutinizing his blonde counterpart. "Shouldn't you be loading up Trouble here to head towards the hospital?"

"Lieutenant Casey is refusing transport to the hospital," one of the EMTs explained.

"He's what?!" Kelly yelled, whipping around to glare at Matt. "What the hell do you think you're doing, Matt?"

"They can set the shoulder here, Sev," the younger man attempted to reason. "They set the shoulder, give me some meds, and then I can go back to the house. There's no need for me to clog up the ER with all of the other guys surely headed there."

Severide ran a hand over his face in frustration, pacing for a brief second before turning back to Matt. "Matt, your shoulder is dislocated…severely dislocated. You were barely conscious when I got you out of the truck. What if you did more internal damage? Or hit your head again? You're bleeding … you know that right?"

One of the paramedics spoke up then. "We need to know whether or not we're loading him up, sir."

"You are."

"You're not."

The two lieutenants locked eyes after chorusing opposing opinions. Kelly's glare softened as he noted the exhaustion and pain still lingering in his brother's eyes. "I can't make him go, can I?" he asked the paramedics.

"No, sorry, sir."

Clenching his jaw tightly, Severide ran a hand through his hair, sighing. "Damn it Matt…Fine. Okay, fine. You," he said pointing at the blonde. "Can get your shoulder fixed here. BUT then you're not returning to the House. I'm taking you home where you will let me worry over you. End of discussion."

"But I get to choose the movie," Matt reminded, pleased Kelly had given in. He truthfully didn't have enough energy to continue to protest. Any further insistence from the older lieutenant would've had Matt on his way to the hospital whether he wanted to or not.

Kelly, meanwhile, swallowed the fear crawling through his veins, and offered Matt his hand. "Right. Let's get you put back together and then you can pick the movie," he confirmed, nodding to the paramedics.

The EMTs pushed up the sleeve of Casey's shirt, exposing the swollen joint. Gently feeling along the shoulder, one of them quickly depressed a syringe full of muscle relaxant into the deltoid. The other grasped Matt's forearm, carefully lifting the arm off of fireman's chest. The blonde lieutenant grasped Kelly's offered hand tightly as fire lanced through his right arm. Severide maintained a steady grip and used his other hand to alternate between grasping Matt's good shoulder and mussing the sweaty blonde hair.

"You're okay, Matty," he soothed as the paramedic wrenched the arm straight before moving it in a circle. There was an audible 'crack' followed by a hollow 'pop' as Casey visibly paled and bit his lip to keep back a partial scream. The EMTs outfitted the Truck lieutenant with a sling and Kelly gently covered the spasm-ridden hand until the muscles stopped convulsing. "How're you feeling now, bud?"

"I can feel my arm again…" Matt breathed shakily.

"Yeah? Bet that feels great," Severide quipped, helping the younger man sit upright. Briefly looking around, he noticed that his squad truck was still idling on the edge of the accident scene, the bustle of activity slowly dissipating.

The paramedics quickly injected Casey with a dose of morphine before bringing forth a clipboard full of paperwork. "Because you refused transportation to the hospital, we need you to sign this form," the one explained. "We also need Lt. Severide to sign this one stating you won't be driving or going home alone now that we gave you morphine."

Seeing that the truck lieutenant's dominant hand was incapacitated in a sling, Severide grabbed the clipboard, earning a raised eyebrow from the paramedics and an amused look from Matt. "What? I'm Trouble Magnet's medical proxy so I can sign the papers for him."

"S'what big brothers are for," Casey slurred.

The EMTs just nodded distractedly, ready to hand the blonde over to his overprotective counterpart. Once the paperwork was in order, Kelly carefully eased Matt off of the gurney, holding him upright. Then the paramedics loaded their empty ambulance and drove away, leaving the two lieutenants standing in the aftermath of the collision.

"Well what do you say, Matty? Want to go for a ride in the Squad truck?" Severide asked lightly, leading the younger man towards the vehicle. "Can't trust you to ride in just any truck now…"

Matt snickered lightly. "Just what I've always wanted, to join Squad."

"C'mon, Trouble…the morphine's getting to you, huh?" Kelly noted, opening the side compartment door. Seeing Newhouse sitting next to an empty seat he gestured towards his usual spot up front. "Take my spot, Newhouse. I've gotta keep an eye on the drugged one, so…"

Easily making the switch, Newhouse was soon seated in the Lieutenant's seat upfront as Matt and Severide were settled in the back. Then the Squad truck was underway, making a brief stop at House 51 to drop off the Lieutenants before heading to support their fellow firemen at the hospital.

A short while later, Kelly was finally able to drag a drugged and drowsy Matt into the space they now shared. Carefully depositing his younger friend on the couch, Severide moved to fetch him a glass of water. "Alright, bud. The first thing we need to do is figure out how to get you into more comfortable clothing."

Taking the glass Kelly offered him, Matt pouted with glazed over eyes. "Then the movie, Kel?"

Rolling his eyes at the drugged blonde, Severide nodded before disappearing into Matt's room. Grabbing a pair of sweats, he returned to the living room to find Casey slumped against the end of the sofa. Noticing the way he was leaning on his injured shoulder, Kelly quickly moved to sit him upright once more. "Jesus, Matt…can't leave you alone for a second, can I?"

"Didn't hurt," Casey countered, letting Severide help him stand upright, muttering under his breath about morphine. Following his friend's instruction, he kicked off his shoes before attempting to unbutton his pants. After a few tries with his left hand, the truck lieutenant cursed and slumped back on the couch.

"C'mon you," Severide insisted, laughing lightly. Standing Matt back up, he swiftly undid the button and zipper on the younger man's pants and yanked them down. Matt obediently stepped out the pants and into the sweats Kelly offered. Then the squad lieutenant tugged the sweats up to his friend's hips and lightly tied them, frowning at the bruise he saw stretched across the blonde's waist. "See? No problem. Now let's get you out of that shirt…"

Removing the tshirt proved to be more difficult as they had to take off the sling and maneuver Matt's injured arm out of the sleeve, eliciting yelps and groans from the incapacitated lieutenant. Temporarily ignoring the pained noises, Kelly focused on successfully removing the shirt and quickly replacing the sling, leaving the blonde shirtless. Removing the shirt revealed the darkening bruise that now graced the other man's chest; a clear indication of the seat belt that had restrained him just hours before. Severide growled lightly.

"Kel…"Casey protested as his friend felt along his bruised chest, checking for any signs of internal damage.

"Shh…" Kelly tsked, swatting his hand away lightly. "You should've gone to the hospital. But since I'm weak, I fell for those damn eyes and took you home. So now you're going to let me fret for just a minute before you pick the movie."

Matt was silent for a second before poking Severide in the forehead. "Hey Kel? Can we watch Brother Bear?"

"Brother Bear? Really?" Kelly scoffed, moving to sit next to Matt.

"Yeah…s'got brothers and an adventure with animals and Phil Collins music and…you said I got to pick," he protested.

"Alright, alright…" Kelly relented, using the remote to select the requested movie. "But if you start singing, we're switching to Fast Five."

Matt agreed, moving to lean against his brother, leaving his injured arm undisturbed. The boys settled in to watch their movie, each slowly drifting off to sleep after a short while.

The smoke was thick, filling his vision and making him gag, despite his mask. He smelled gas and char and began to slowly register sounds. There were screams and the penetrating beeps of PASS alarms going off all around him. Where was he? What had happened? Finally clambering to his feet Kelly moved unsteadily towards the screams, moving instinctively. Something was drawing him this direction; someone needed him.

Turning the corner of the stone building, Severide came face to face with a living nightmare. There, sprawled out on the concrete, lay Leslie Shay, a pool of blood forming around her, eyes staring blankly back at him. Screaming her name, Kelly collapsed to his knees, cradling her still form to his chest. He knew she was dead; these nightmares were nothing new. He'd be allowed a few agonizing moments holding onto his other half before his subconscious would rip him back to reality.

Suddenly, the scene around him changed. Severide was thrown into the scene he'd witnessed earlier that day. He watched over and over again as Truck 66 slammed into the side of 81, repeatedly watching Matt's side be bent in and warped. He ran out of the truck, scrambling towards the fallen fire engine, noting the distinct lack of his team. Kelly was alone, racing to save his friend. The asphalt seemed to stretch and lengthen intent on hindering the lieutenant's progress. Eventually making it to the overturned vehicle, he practically flew up the side of the truck, not caring if he damaged himself on the way up. Finally coming to Matt's door, he anxiously peered inside.

The blonde lieutenant hung limply as before, but this time he was entirely alone and covered in blood. Screaming his brother's name, Kelly smashed the window with his elbow, frantically reaching for Matt's neck; needing a pulse to end this nightmare. But no pulse beat beneath his fingers, no blue eyes blinked wearily up at him, and no voice told him not to worry. Sobs erupted from Severide's chest as he reached to gently tilt Matt's face upwards. "I'm so sorry Matty…I'm so sorry…you and Shay…oh God…"

Kelly jerked awake with a gasp, breathing erratically. Feeling a comforting weight on his shoulder he moved to see Matt snuggled contently into his shoulder. Running a hand over his face, Severide let out a shaky breath. Now that they were home, all he could think about was how close he'd come to losing Matt. "Not now…Andy, Shay…not Matt…" he muttered.

"Kel?" Matt sleepily slurred. "You okay?"

"Yeah," Kelly cleared his throat. "Yeah, I'm alright…go back to sleep."

"You didn't lose me," the blonde persisted, fighting the morphine-induced haze. "I'm right here because you saved me again."

"Guess I did, huh? We were supposed to have a talk about that," Severide remembered, biting back his emotions. "You made me rescue you again, Trouble."

"I'm sorry, Kel," Matt insisted. "I didn't mean for you to worry again."

The squad lieutenant scoffed at that. "Yeah, like you intended for your precious truck to get Tboned. I think we can agree that it wasn't your fault, Matty. Just scared me a bit is all. But, you're right…you're okay, I'm okay…we have each other."

"Brothers," Casey promised.

"Brothers," Kelly agreed, settling back on the couch with Matt. "Go back to sleep, bud…Big Brother's orders."

Matt complied, relaxing against his brother. They'd always be in some sort of danger in their line of work, but at least they knew they could always count on each other to be there. They were brothers, bonded by fire, and they'd always have one another's back.
