Chapter 13

Kelly focused on his breathing until the wave of nausea passed, his eyes still fixed on the display of his phone. He took a deep breath of fresh air, coming from the nearest open window, but he was struggling to calm down, the idea of losing the man he regarded as a brother, and a little boy now occupying his entire mind…"Ahhh, damn!" He cursed quietly when Matt twisted his face in agony, without realizing he was being filmed.

A wave of adrenalin rushed into Kelly's system, causing him to lose touch with reality, everything around him except for the two faces on the screen becoming just a blur…Tightening his grip on the phone, he started moving forward in the direction of the stairs…

"Kelly - " Doctor Shaw's voice sounded from the office, Severide's brain registering the opening of the door and the words spoken, without making sense of anything.

Kelly walked out of the building without noticing the concerned glance the receptionist shot him. Making a few more steps towards the street, he looked left, then slowly turned his head right, but his Camaro was nowhere to be seen. "Damn!" Was the only word that escaped his lips when his eyes finally fell on Matt's truck parked on the street leading to the very small park. He got to the car, his attention still focused on the phone screen, and froze on his feet next to the passenger's door, his mind somehow concluding that he could not open it, that he could not go anywhere…nothing made sense anymore, nothing…he was afraid to use his phone to call Erin as the live-stream could stop, he could lose Casey…

Xxx

Erin pressed the "end call" button on her phone, muttering a curse. She slammed it on her desk, Antonio and Halstead looking up, having been watching video tapes from security cameras for the past two hours.

"No answer?" Jay asked, not really to hear the "no" his partner uttered, but to show her that she could talk to him.

"Casey's usually - "

"Relax." Antonio interjected, ignoring the very bad feeling he was having…it wasn't in Matt's style to not answer his phone for over three hours.

Their small chat was interrupted by Mouse, the new tech guy Jay had vouched for, who muttered "yes", balling his fists in excitement. "You'd wanna see this."

Voight's entire team gathered around the computer. Mouse pressed "play" and they all watched Spellman, holding Logan's unconscious body, and Hadley get into a dark blue pickup and drive away.

"I'll check the car." Ruzek volunteered.

"Put out a BOLO!" Voight barked just before Erin's phone rang. She grabbed it, believing it would be Casey, but the number was one she had not seen before.

"Lindsay." She grumbled.

"Detective Lindsay, it's Doctor Shaw."

"Kelly okay?" The words escaped her lips instantaneously, her gut churning, her face losing its color.

"I was hoping you'd tell me…He got a phone call and just left, his jacket's still in my office. I was sure he was going to come back so I did not go after him, but it's been nearly five hours since he left…I rang Lieutenant Casey first, but no one answered."

"You called Kelly?"

"I tried."

Erin sighed, her free hand landing on her coat…she had tried Kelly's mobile about three hours earlier, assuming that his meeting with the shrink hadn't been over yet. "Okay, thanks. I'll…I'll see what's going on."

"Let me know."

"Sure." She uttered before the line went dead. Ignoring all the people now staring at her, she dialed Kelly, holding her breath without realizing it…

It was one of the first sunny days in Chicago this spring and no one found it unusual that a man, wearing only a dark green shirt, no jacket on, had been sitting on a bench in the small park for over five hours, staring at his phone motionless…But Lieutenant Kelly Severide was paralyzed with an overwhelming sense of fear and unreality, as if he was detached from the world around him, not able to think, to stand up and go anywhere, to look sideways as he could not know when the live video would stop, when Casey and Logan would disappear from the screen. He had already seen Spellman untie Logan, bring him a burger, coke, water…He had seen Casey struggle to move and shift his position, unsuccessfully, but he was alive, it's all that mattered now.

Kelly's phone jumped up and down on his lifeless hand, almost falling down, Erin's name appearing on the screen, on top of Logan's and Matt's faces. "Erin…PD." His brain finally put two and two together. Against his own better judgement, he took the call, opening his mouth to say something, anything, but no words escaped his dried throat.

"Kelly!...You there?" Lindsay's petrified voices sounded in his ears, her voice making him focus.

"I'm…I'm here." He uttered, not sure if his voice was loud enough for her to hear.

"Kelly what's going on? Where's Casey?"

He shot a glance at the screen to check that Matt was still there. "He's…they have him. They have him!"

"What?...Where are you?"

Kelly looked around, his eyes darting between the tall building not far from where he was, the street and Matt's truck, and the park area surrounding him. "The park…near Shaw's office." He managed to explain, hearing Lindsay bark at Antonio to get the car and meet her outside.

"Kelly, stay there! I'm on my way!"

"Yeah."

"Hey, keep talking! You gotta calm down and tell me where Matt is!" She was trying to keep the line open. Hearing his voice over the phone meant he was okay, because, yeah, Erin Lindsay was also scared now.

But Kelly could not say a word more….He had to watch, powerless to do anything, as Spellman walked closer to Casey with a glass of something, Severide praying it was just water. Squad Lieutenant ended the call just before Spellman grabbed hold of Matt's blond hair and pulled his head back, Casey trying to fight the strong grip with whatever energy he had left. Spellman turned Matt's head in the direction of the camera, a smile dancing on his face, then released his grip. A second later he used his right hand to lift Casey's jaw, squeezing it so hard that his lips opened, and slowly poured the clear liquid into Matt's mouth…

He had no idea how much time had gone by since he had ended Lindsay's call when her husky voice, coming from the distance, snapped him out of his trans. "Kelly!" She kept yelling, her eyes finally landing on the motionless figure of her fireman.

"Damn, Severide!" Antonio imprecated, getting at his side first, Erin joining them seconds later. While Lindsay was just staring at the man she loved, trying to figure out what was wrong, Dawson took his jacket off and covered Kelly's slightly trembling frame, glancing at the phone in the lieutenant's hand…

"Hadley has Casey." Kelly finally spoke, the warmth, the familiar faces, her gentle touch bringing him back to reality, making him aware that he had already wasted almost six hours, time they could have used to find Truck's Lieutenant.

"Look." Antonio's eyes pointed the screen. She expected to see many things, but a crying child and Matt struggling to free his hands were not among them.

What happened next horrified them even further. The images of the people disappeared, replaced by five words…"Can you save them both?"…The display went blank, the man watching them from a safe distance deciding that Kelly had seen enough.

Kelly jumped on his feet bewildered, angry even, mad that CPD's appearance had caused the live video to be turned off. Not letting out anything more than a snort, he lifted his right hand up, but Erin grabbed it and took the phone away before he could smash it on the ground. "Evidence." She told him firmly, not sure if his mind was making sense of her words.

"I…I need to go back to the apartment." He mumbled as millions of thoughts and ideas, all of which included Hadley's dead body and Spellman's funeral, rushed into his head. "Need my car."

"Okay." Lindsay replied, covering him with Antonio's jacket that had fallen on the bench when he had gotten up. She could hear Dawson talking to his sister on the phone a few step away, telling her to get to the district as quickly as possible, not revealing more details…yeah, they were all heading to the district, no matter where Severide wanted to go…she wasn't letting his shivering, anxious frame out of her sight.

"How's Logan?" Spellman demanded before Hadley even had the chance to announce his presence. Kevin didn't rush his answer. He made his way to the corner of the big room, adjacent to the one Matt was in and put down a cardboard box of brake fluid bottles next to the chlorine powder already there.

"Doing great." Hadley answered with mild sarcasms, not liking Spellman's concern for the boy. He knelt on the floor and made sure the lids of the bottles were tightly shut…he didn't want anything to ruin his perfect plan. "Can't say the same for Lieutenant Severide."

"Why?" A smile appeared on Spellman's stony face.

"Seemed broken" Kevin snickered. "His face when you cut off the live-stream…"

"Told ya he's the dead man walking!" Spellman hissed, burying his right hand into the pocket of his jacket to make sure he had some cash in there. Satisfied that he was going to have enough for a cheap vodka and dinner for the boy they had dragged into their game, he blocked Hadley's way, raising his eyebrows expectantly. "I wanna see the others join him in hell!

"Told you, tomorrow!" Kevin answered in a calm manner, making a step to the left and then continuing on his way to the dirty chair on top of which a small backpack lay. "Do your job and let me work now!" He muttered, taking a match box out of the left side pocket.

Lindsay guided Kelly to her desk, Scott pacing around the crowded room like a lion in a cage, Gabby sitting on her brother's desk chair, the color combination of her clothes suggesting that she'd left home in a hurry. The moment she saw Kelly walk in on autopilot, his mind only party registering where he was, not having the power to protest and demand for Lindsay to take him to his place, the tears Gabby had been holding for the last twenty minutes just fell down her cheeks…Matt not being there with Severide just proved her that she had been right – something bad had happened…

Antonio was at her side instantly, crouching so he could wrap his hands around her. "Gabby…shhhh."

Voight's eyes darted between Detective Dawson and Erin, whose left hand was placed under Kelly's cheek, the right one rubbing comforting circles around his back. Seeing Lindsay so vulnerable broke Hank's heart…the monsters torturing the fireman were upsetting her…and nobody was allowed to make his girl cry…nobody was allowed to kidnap kids and firefighters, even if it was the one he didn't like that much.

"What've we got?!" His hoarse voice boomed.

"They've kidnapped Casey." Lindsay's voice was quiet, in contrast to her mentor's. She let go of Kelly when Nadia brought a glass of ice cold water and he poured the liquid into his mouth, not able to stop thinking that he'd done nothing for hours, hours that could be crucial…guilt hitting him harder than a train could…

"I saw Spellman." Severide's voice was surprisingly even. "They sent me a live-stream from where they keep Logan and Matt…saw Spellman."

"How is he?!" Scott grumbled from the behind the white board now displaying Hadley's and Spellman's photos. "You should have called me!" He moved forward in the direction of Lindsay's desk, Olinsky blocking his way, gently grabbing him by the shoulders.

"I was close to losing my daughter once! You gotta stay strong!" Olinsky whispered in his ear, only Hank hearing those words. Rice snorted and jerked his arms free, then turned around and leaned on the wall in the corner of the room.

Erin shot Kelly a glance, then grabbed his phone that she had put on her desk. "Mouse!" She barked, the tech guy not intimidated by her. "I don't care how, just trace that video!"

Jay gave his friend a look saying "don't argue", but for his surprise Mouse jumped off his seat in excitement. "The BOLO's just come back."

Gabby's head turned to look at the tech guy who had just given her hope…hope that her fiancé would be alright. She let go of her brother and Antonio jumped on his feet, stepping to the desk Mouse was using. "Gimme the address!" He grumbled, patience not something he had in that moment. It took Antonio only a quick glance at the street name to recognize it. "It's in front of fifty-one!"

"He's messing with us!" Ruzek snorted in anger, doing what everybody else was – grabbing their gear, mainly their weapons.

The commotion around him was Kelly's clue to get up and finally do something, save his friend, kill Hadley…it sounded so simple in his head – kill Hadley. End of their problems. He pushed himself upright, ready to join Voight's team, but stumbled over the desk's leg before making even a step forward, Erin's quick reflexes preventing both of them from ending on the floor.

"Whoa, cowboy!" She pushed him back on the chair. "You're not going anywhere, need to get your statement when we get back…you're the only one to have seen Spellman's face on the video." Her tone didn't leave room for negotiations…she could not let him go anywhere alone.

"Both of you," Voight looked at Rice and then at Severide. "Keep each other company. Will call you if we find anything."

Xxx

Scott and Kelly waited all night…neither of them had said a word for the seven hours they've spent in the desk area of Intelligence, Mouse too immersed in his work – tracking down the source of the live video, to talk to them. Antonio had instructed Nadia to take Gabby home and stay with her…

They were still waiting when the morning sun shone through the kitchen window and Kelly poured yet another shot of espresso in his mug, cursing quietly when he saw the time…their shift was about to start in half an hour…maybe…Second Watch was down so many people that Severide wasn't sure if Boden hadn't requested other companies for the upcoming shift…The two lieutenants were not there, one of them maybe never coming back…Kelly shook his head, trying to get the thought of losing his brother out of his mind, but it didn't want to go away…Gabby was probably taking time off as well, Herrmann not leaving Luke's bedside, Scott in the same shoes as him…

He was grateful when he finally heard Erin's voice from the desk area, Jay trying to start a conversation with Scott. Finishing his coffee, he left the mug on the counter and joined the two detectives, the rest of Voight's exhausted team being downstairs with the car. With arms folded together across the chest, he stared at Erin, desperate for news.

"The car's empty." She uttered, not missing the tears welling in Kelly's eyes, Scott punching the whiteboard, making them wince. "We've searched the entire firehouse, but it's clear, no sign of…anything!"

"Track that damn thing down already!" Kelly snapped, looking at Mouse with a scowl, the later raising his brows, the sleepless night taking its toll on him.

"You think it's that easy?!" Mouse's eyes were daring Severide to say yes, his military training kicking in. "I don't even have that video! If you'd come here when it was live - "

"Hey!" Lindsay growled, raising her index finger.

"Let's take a break." Jay urged his friend, pulling him away from the two firemen, Scott deciding to follow Halsted out for some fresh air. He was sore, angry, devastated, powerless...No, he did not blame Kelly…how could he? He knew Hadley himself, had had beers with him many times…Never in his worst nightmare had he imagined that a fellow firefighter, a brother, would do what Kevin had.

"I'll be back in two minutes and you and I are gonna talk!" Erin kept her husky voice firm. She needed Kelly to pull it together, for her, for Matt, for the little boy. "Hey…you and me, together, right?!" It was a reminder of the promise she had given him the day he had asked for help after Shay's death, the day he had tried to take his life in hands.

"Yeah." Squad's Lieutenant uttered, watching her disappear in the direction of the restroom. He was about to sink into her desk chair when his phone, now connected to the computer on Mouse's desk buzzed, the MMS sign appearing on the screen. Not thinking twice, he pressed "open", the message containing two pictures and text – Logan holding a bottle of brake fluid, the same liquid being poured on top of an unconscious Casey, a wound somewhere on his head bleeding, leaving red marks on his face, and words – "tick tack". Kelly fought the new wave of panic and shock, not able to stop thinking of Matt's head injury that had almost claimed his life, his cracked skull and the beating on the head he had taken…and Logan's petrified, innocent face…Kelly disconnected the phone from the computer, threw it gently on Lindsay's desk and took off…to find his brother and kill two monsters.
