Requested By Anon: Could you do a Kelly x SquadFF!Sister. Kelly’s new girlfriend doesn’t like his sister. Kelly doesn’t notice this and wants them to be friends. His sister try’s for Kelly but when he’s not around or not looking the girlfriend is a b****. When the sister mentions it to Kelly, he brushes her off basically saying she’s imagining things. One day Kelly is with his gf and he gets a call something has happened to the sister (minor emergency, nothing crazy unless that’s what you’re feeling) and when he tells his gf he’s gotta go she gets mad and basically gives him the “its me or her” speech and he breaks up with her on the spot.
I know it’s kinda long and specific but feel free to change anything you want! All I ask is that if you do write this, can you please make the reader (sister) very not dramatic. Like she tries not make a big deal out of it even though it bothers her. Also big fan of badass women… just saying. 😉

The past 24 hours had been one of the most taxing shifts in a good while, Squad had been called to back-to-back long, complicated, rescues which had left you feeling pretty zonked and somewhat deflated, in need of a recharge. However, other than a deeply satisfying and long sleep, you had personal matters that required your attention. One such matter was that you would be meeting Kelly, your big brother and Squad Lieutenant, for drinks at Molly’s. This wasn’t just a hang-out that you could call off, however, as tonight you’d be meeting his new girlfriend, Olivia.
You tried your best to be supportive of Kelly and his romantic endeavours, you knew that your brother had a heart of gold and always went in with the best intentions. Yet, you also knew he had emotional baggage that he was yet to face full on, and although you and he would talk about anything and everything, it was still down to him to make decisions for himself. So here you were, willing to give Olivia your most polite, undivided attention and see what she was all about, whether Kelly had made a good choice or not remained to be seen. He had seemed really happy of late, and who were you to put a question mark over that?
Arriving at Molly’s your bladder instantly decided that before drinks it would need a visit to the bathroom, so giving your brother a quick wave and Herrmann a salute you headed straight to the restroom. You noted on your walk through that Kelly was alone at the bar, you just figured Olivia hadn’t arrived yet and thought nothing of it. In your brief cloud of thoughts, you didn’t notice someone exiting the bathroom, walking straight into them and snapping yourself out of your musing.
“Oh shit, I’m so sorry, I was totally somewhere else! My bad…” You spoke quickly, apologising profusely as a small embarrassed expression came across your face, smiling to diffuse the annoyance the stranger might feel.
However, the stranger scoffs, shoving past you as she comments, “For christ’s, just pay attention! What’s wrong with you, are you stupid, bitch?”
Leaving you standing there dumbfounded as it was clearly an accident and you had apologised, there was no need for that kind of venom. Before you can even respond the door to the main bar area swings shut and the stranger is back out into the foray.
You head to the bathroom for the pee you’d gone for, feeling irritated that you hadn’t had the chance to call that woman out on her nastiness. You were used to stressed out and sometimes volatile people whilst working on Squad, but experiencing that kind of behaviour in a bar really got under your skin.
Washing up and making sure you were presentable for Olivia and Kelly, you head back out into the main area of Molly’s, laughing quietly as Herrmann gives you an encouraging thumbs up on your way back to where Kelly was sitting, now with a woman with long, straight, almost midnight black hair…
You recognised that hair. You had just seen it swishing past you outside the bathrooms.
“Of course, it would be wouldn’t it.” You exhale in irritation, muttering to yourself as you take the last steps toward Kelly and his companion. Plastering the best smile on your face.
“Kelly.” You wrap a friendly arm around your brother’s shoulder, waiting for him to introduce his new demonic girlfriend.
“Hey! I’m so glad you’re here. Y/N this is Olivia, Olivia this is Y/N.” The lieutenant gestures to the woman beside him, and it’s like looking at a completely different person from minutes ago. Her eyes are softer, less hardened, and a sickly sweet smile greets you - it’s almost shy. She even reaches in to give you a half-hug complete with a pat on the shoulder. You want to laugh in her face, but you don’t show any other emotion other than polite joviality and return the gesture.
“It’s SO amazing to finally meet you, Y/N. Kelly has told me so much about his amazing little sister.” Your eyes do light up a little, not because of Olivia but because Kelly had been talking about you - he had always been so supportive and encouraging of you, he was the reason you fought so hard to get a place on Squad 3 with him. Working with your brother was the dream, and he had let you cut no corners. You were sure that you’d had one of the more gruelling application processes for Squad.
“The same for you, Olivia. It’s really nice to meet you.” You smile as best you can, slotting yourself next to Kelly at the table they’d moved to.
The night was going somewhat successfully, trading work stories, interests and future hopes for trips, experiences and so on, you could feel your irritation from before thawing out… That was until Kelly decided he needed to pee. Something you couldn’t be mad at him for, but desperately wanted to given what happened as a result.
Kelly had left you and Olivia to make small talk, and you had decided that perhaps you had caught her in a bad spot outside the bathroom earlier, choosing to hope that the person you’d been talking to all night was genuinely the kind and the interested person she seemed to be.
“I’ve really enjoyed this tonight, Olivia. It’s so good to see Kelly happy and excited about things other than work.” You smile, sipping at your drink, waiting for some kind of response.
Olivia simply stares at you, an arrogant smirk on her face, she raises an eyebrow.
“You think this is for you? To enjoy tonight? I’m here because your brother wanted me to be, don’t get it twisted. We’re not going to become best friends or fun sisters-in-law or whatever. Kelly’s got a right to have a life away from his little sister hanging off of him at every moment, don’t you think?”
The words cut into you and you feel your body turn cold, she’s still got a smile on her face for anybody that might look over to the table and see whether Kelly’s sister and his new girlfriend are getting along. You feel the rage bubbling up in your chest, jaw clenched, you really didn’t understand what this woman’s problem was.
“I didn’t… I’m sorry, what have I done to offend you? What happened earlier was an accident, and I know Kelly has his own life, I would never-” The sound of her grating laughter cuts through the air, and you have no idea what’s going on until you feel Kelly return beside you.
“Kel, Y/N was just telling me stories from when you were kids.” She grins, giving him the doe eyes as you sit dumbfounded.
“Is that so, huh? Nothing too embarrassing, I hope.” Kelly turns to you, and you realise you’re frozen in incredulity. Seconds pass by, and your brain kicks back in, shoving out your best half-hearted laugh and smile. “Nothing too embarrassing, just the highlights” You jest, but really you just want to throw the rest of your drink in Olivia’s face. Your enthusiasm doesn’t quite land, Kelly gives you a weird look, but he figures you’re tired just like he is from the previous shift.
“Sorry, it's my turn to pee.” You mumble, as you get up and make a beeline for the bathroom, your emotions surging through your body, ready to spill out in either tears or a temper.
You shove your way into the restroom, immediately turning on the cold tap to splash some water onto your face, blinking back the angry drops that push their way past your eyelashes. Fist clenched against the counter by the sinks. Breathing hard as you try to corral your anger. Being too much of a nuisance, interference or burden on Kelly has long since been your no.1 fear, and you have always tried to let him lead an independent life without relying on him too much as a younger sibling. You thought you’d been doing a good job, in fact, you were certain that you and your big brother had a wonderful dynamic, and yet Olivia’s words had rattled your cage so thoroughly.
The minutes pass and you’re finding it hard to get yourself back out there, messaging Sylvie to ask if she could make up some sort of excuse about your shared apartment with her, something that would require you to go back and help sort it out.
Just as you think you’ve rallied yourself back together the bathroom door opens, and the last person you want to stand there is watching you with cold eyes.
“You’re not sulking in here, are you? I was just giving you some adult advice.” Olivia snips, and you want nothing more than to strike your hand across her face.
You were in your mid-20s, and you had one of the most serious and taxing jobs around, you knew what it meant to be an adult and you were already sick of this witch making you feel small. If Kelly could hear her now…
“I’m all good thanks, not looking for any extra unsolicited advice.” You bite, this time side-stepping around her to leave the bathroom.
“You’re not running off are you?” She calls out, just as you reach the door back towards the main area again.
You take long, quick, strides towards Kelly who’s now got Matt for company. You greet the Captain briefly before giving your excuse to leave to Kelly.
“Hey, Matt… Listen Kel’, I’m so sorry but I gotta dash. Sylvie called and said the showerhead won’t stop running, it’s making a weird sound. I gotta go help her and get hold of the landlord. I’m so sorry for rushing off.”
Even to your ears, the excuse sounds weak, but Kelly doesn’t show any signs of disbelief,
“Oh, no sweat. You do what you need to, we can do this again soon, yeah?” Kelly smiles, squeezing your arm.
“Of course, see you tomorrow. And nice to meet you, Olivia. Bye Matt.” You hurry your goodbyes, only glancing at Olivia who gets to the table as you start to depart, seeking the fresh air and distance from that situation as quickly as possible. Not noticing the curious look Matt gives you as you leave, grateful that he hadn’t offered to go help Sylvie, seeing as fixing things was his forte.
-
When you get home to Sylvie she’s waiting with some drinks of her own and some snacks, music and a listening ear. You had tried to not let it get to you so much, but in the safety of privacy with one of your dearest friends you felt the angry tears fall.
“She is so condescending, Sylvie. Jesus Christ… I don’t even know her and yet she’s got under my skin. I have always tried to let Kelly be Kelly and not interfere. And-”
“And what’s changed?” Sylvie queries, eyebrows raised in that big sister, no-bullshit, way.
“What? Nothing’s changed…”
“Exactly, Y/N. You haven’t changed, you haven’t done anything wrong. You and Kelly are a sibling fortress, and this woman needs to back the hell up if she thinks she can come between you.”
You’re stunned into silence for a moment, this was something you already knew but had let your mind run away from in an evening. You hadn’t done anything wrong, you were there for Kelly always and you hadn’t let your misgivings from tonight get in his way. You had done everything you could to keep the peace for your brother’s sake.
Your eyes filled with “Oh shit” meet Sylvie’s “Uh-huh, I’m right” expression.
“What do I do, Sylv? I can’t just let her walk all over me, but I don’t want to make a fuss in front of Kelly.”
Sylvie links her arm with yours, “Y/N, listen to me very carefully. If Kelly found out you had let this all happen and kept going, well how do you think he’d feel, hm? What are the chances of him ditching you for a woman he’s known for a minute compared to your lifetime?”
“Slim.” You murmur. Yet, something about the happy glint in Kelly’s eye told you it may not be as straightforward as telling him and then it all being over. A part of you was still hesitant to shatter the illusion that his new girl was as sweet as pie.
“Slim to not happening at all, there's no way.” Sylvie corrected.
“So I tell him?” You ask, needing confirmation that you weren’t crazy and that you had every right to go to your big brother about this.
“You tell him, you let him know exactly how it all happened, he’s not stupid and he is generally good at seeing people for who they are.”
You nod, resting your head on Sylvie’s shoulder. “You’re the best, Brett.”
“Only because I am friends with the best kind of person, Severide. Now, what are we getting drunk with, and are we ordering takeout?” You laugh at that, in total agreement with the new plan, squeezing her in a hug as you pick up the remote to find something for you and her to enjoy whilst forgetting about bitchy people snooping around in your life.
-
The next shift with Kelly is a challenge, to say the least. Rather unexpectedly your brother is particularly hard on you, through maintenance, through drills and, rather frustratingly, on calls. For some reason, you couldn’t do anything right in your brother’s eyes and it was starting to piss you off. Things you did that would have been perfectly acceptable or up to standard for him were suddenly done too quickly, or not taken seriously enough on your behalf; it meant that, despite your best efforts to appreciate that you would be treated like any other firefighter, you were starting to get short with your Lieutenant. It hadn’t gone unnoticed by your crewmates either, with Joe, Capp and Tony all giving each other a look as if to say “What the hell is happening?”
The most recent call had been the last straw, on the return journey you had sat next to Joe in the back simmering with rage. Kelly had undermined you and called you out on something in front of the entire scene of responders, for something you were sure had been the appropriate course of action during the call. Kelly’s tirade had been such that even the Chief had to tell him ‘Enough’ and sent 81 and 51 back to the firehouse, making Squad 3 clean up alone. You hadn’t answered back, or protested, accepting your Lieutenant’s words as something to take on board, yet inside it felt like a fire was ripping through you.
You had swept and hauled debris in silence, opting to work next to Capp and away from your brother who was discussing something with Joe. You couldn’t even look at him as you passed him to get into the truck, you were close to ripping into him personally and unprofessionally - even though you considered his behaviour to not have been appropriate.
By the time you’d got back you were nothing short of having a breakdown, yet you held your head high and chose to simply pack away your gear ready for the next call, electing to find Matt Casey as soon as possible.
Making a beeline to the Captain’s office you knocked, barely waiting for the “Come in” before opening Casey’s door and pushing it firmly shut behind you. Sinking down onto the floor between the wall and his bed.
“What’s up, kiddo?”
“If you don’t help me figure out how to keep my cool, I am going to strangle my Lieutenant, your best friend.” You muffle a yell into your palms, looking up at Matt with imploring eyes.
“So he’s not your big brother anymore, just my best friend?” Casey’s face carries a hint of a smile, but he senses you’re not in the teasing mood.
“Case, you heard him out there today, he’s been up my ass all day. Did that bitch break up with him or something, because I-”
“Woah, hold up. You don’t know?” Matt’s eyebrows raised in confusion.
“Know what?” You’re focused on Matt now, your heart hammering in anticipation of what you didn’t know.
“Olivia told him that you tried to start a fight, and called her some pretty uh, nasty things. He came to me asking if you’d said anything, and I said I hadn’t seen you since Molly’s the other night. I figured this whole mess from today was the fallout of that…”
You stared at Casey with what felt like your entire stomach about to fall out of your ass.
“She, what?” You murmured, your head was pounding and your mouth had gone dry.
He rose from his chair, coming to sit on the floor with you, a hand on your shin in reassurance. “I know, I told him I didn’t think it sounded like you, but he was pretty mad, Y/N. I couldn’t calm him down all that much.”
Your face fell into the palm of your hand, you were so full of adrenaline you didn’t know what would happen to it next.
“That bitch. That honest-to-god bitch… All I did was accidentally walk into her at Molly’s, Matt. That’s it! I apologised and she in return told me how useless I was, then accused me of leeching off my brother, then she tried to make me feel like a fucking child… All the while I’m doing my best to keep the peace and not upset Kelly. I’m gonna… hoo, boy, I am gonna lose my goddamn mind.” You exhaled sharply, suddenly springing to your feet which caused Matt to scramble back and do the same, not sure where this was all going.
“Y/N, don’t do anything you can’t take back…” Casey warned, eyeing you with concern.
You can’t speak, shaking your head, patting his arm as you leave his office without another word.
Matt cautiously follows in your quick footsteps, watching as you head towards Squad 3’s table. He swallows, scratching the back of his head, waiting for the implosion.
You come to stand by Kelly’s feet, he doesn’t look up from his newspaper as you stand patiently. “Lieutenant? You got a second?”
“Can this wait?” He replies, not even looking up at you. You bite your lip, willing your anger and upset to go away. You didn’t want to do this in front of the firehouse.
“Unfortunately not, sir. It’s an urgent matter.” You bite your tongue, keeping it amicable, waiting for your brother’s response.
“Alright, my office.” He replies emotionlessly, getting up from his armchair as he wordlessly heads back in the direction you’d come from.
Matt eyes you sympathetically, and you smile weakly, steeling yourself for the conversation you were about to have. Joe, Capp and Tony eye the captain, looking for extra gossip. Matt shakes his head, “Back to work, or…whatever it is you guys do out here.” ignoring their noises of disappointment as he heads after you and your brother, wanting to be some kind of mediator if it got too heated.
Kelly stands by the entrance to his office, waiting for you to get inside the space before closing the door and shutting the blinds.
Next door you hear Casey's door shut, and you know he's on standby if anything gets out of hand.
You stand in front of your big brother with arms folded, a defiant expression on your face. You weren’t going to take any of this bullshit, and you weren’t going to let Kelly have the wool pulled over his eyes.
Kelly’s jaw is clenched, he speaks in a deadly serious tone.
“Explain yourself.”
You swallow a scoff, shaking your head as you look at him. “Explain myself? You really think I am nasty enough to make your new girlfriend feel unwelcome? To get physical with her? To jeopardise your contentment for my own selfishness?” You stare him out, daring him to actually say yes to any of those. You can see the faltering in his eyes, he knew you, he knew how kind you were, how strong and loving you were. Yet, Olivia had put on a good show and for some reason, he couldn’t see past it.
“She was crying that night after Molly’s, Y/N. She was really upset at the way you treated her,”
You shake your head in disbelief, eyes closing for a second, searching for composure.
“I accidentally bumped into her on the way to the bathroom, Kel. When I arrived that night, you remember? That’s all that happened, I bumped into her and she called me a “stupid bitch”, and then for the rest of the night proceeded to accuse me of selfishly taking up your time, of being needy, of being a child.”
There’s silence between you, Kelly shifts awkwardly on his feet, he knows when you’re lying and he can’t see a hint of it in front of him. Still, he can’t understand why Olivia would have been in hysterical tears over nothing. You can see the wavering in his decision, you can see that he’s not going to fully commit to seeing your side of the story and your heart sinks.
“Kelly, I don’t want you to say another word without you really considering what comes out of your mouth next. Just know that if we lose this great family between us because of something she made up… I can’t take that, Kel. You’re my no.1, the one I trust…I thought I was the same to you.”
Your brother’s eyes are full of emotion, and you swallow, you just want to break down and beg him to believe you. You wanted to be strong though, to be believed because it was the truth and not because you’d made a fuss. And just like that, the cruel hand of fate sounds the alarm, and the voice asks that all units from the firehouse attend. You don’t say another word to your brother as you both leave in a hurry to get to the truck.
-
Sitting in the truck waiting to arrive on the scene gives you enough time to get your head together, as always you had a job to do and there was no room for the racing thoughts in your mind.
Pulling up outside a three-story home a blaze taking hold comes into view on the west side, you pile out of Squad 3 and head towards Chief Boden, masking up as you go, checking each other’s SCBAs as you listen to who is going where.
Your Squad is sent to the upper floor and you’re behind Kelly as you march up the stairs, announcing yourselves as you go, looking for any potential victims. Room by room you search, under beds and in closets, the neighbour next door had told you as you were going in that a large family lived there, with two parents and 5 kids. She wasn’t sure if they were home or not, but she knew that sometimes the kids would stay home alone if the parents had to work.
At the same time outside was the eldest child talking to the Chief, they had been found in the basement, crying hysterically as they explained that their 6-year-old brother and 10-year-old sister were still in the house. They had been playing hide and seek.
As you shut one door and go to open another, you hear what you think is a wail coming from above your head. You look up to see the hatch is partially open,
“Squad 3, come in.” Your radio comes to life.
“Copy you, Chief.” You answer Boden, still eyeing the gap in the hatch.
“There's a 6-year-old and a 10-year-old still in there somewhere, you have five minutes, Severide.”
“I think I see one or both of ‘em chief, the attic hatch is partially open, I think I’ve got movement.”
“I’m sending you Truck 81 on the East side to assist, can you get to that window?”
“Copy, Chief, I’ll get us to the East window.” You let go of your radio, picking up your halligan as you jump to reach the handle to the pull-out steps. Calling out.
“Fire department! I’m coming up!”
Over the radio you can hear that Capp and Tony were coming back out to assist below, whereas Kelly was relaying the fact that he’d found the older kid in a bedroom, he was bringing them out too. So that left you with just the six-year-old.
With a quick climb, you were able to shine your helmet into the smoky confined space, revealing a terrified-looking boy coughing and crying, huddled in on himself by the hatch.
“Hey, buddy. My name’s Y/N, I’m here to help you, alright? You’re just gonna hold on to me, and then we’re gonna climb back down. Easy peasy, huh?”
The boy whimpers, shying away as the fire roars down below.
“Listen, sweetheart. I know it sounds scary, but it’ll be scarier if you stay up here, alright? We’ve just gotta get to a window upstairs, and my friends are gonna have a fancy ladder waiting for us, they’re gonna help us too, okay?”
You lean further in, painfully aware of the groaning of the house’s structure beneath you, you beckon the child with your hand-clad gloves.
“Come on, kiddo. You got this, I won’t let you go, and we’ll be okay.”
The boy wails again but this time shimmies forward,
“Okay, that’s it, you’re doing great, sweetheart. Just wrap yourself as tightly as you can around my neck, and then I’m gonna climb down with you, yeah?”
He nods frantically, instantly getting a death grip around your neck, it makes you almost want to laugh. “That’s a good job, okay we’re going down now, just stay close to me and don’t look.”
With careful steps you push your body out to allow for the boy’s frame, steadily moving down until you feel the solid floor beneath your boots. Though solid, with each additional bit of your weight you can hear it protesting, prompting you to move a little bit quicker to the rendezvous, the staircase now engulfed in flames.
“Chief, I have the kid, we’re coming to the East window now.”
You move quickly, arriving at the window where you can see that Casey had broken the glass to get you and the kid out. You hand off your precious bundle to Matt, waiting for them to descend enough so as not to add too much weight to the top of the aerial.
Behind you you can hear the fire spewing and latching onto the upper floor, grabbing at the doorframe to the room you’re in. You watch in anticipation as the glow grows stronger behind the door you’d shut. Glancing out of the window you can see that Casey is nearly at the bottom to Mouch, so you start to turn yourself around and climb out onto the aerial too, as you do so you hear the telling sound of the impending flashover, trying to correct your feet fast enough to beat the powerful force of the heat and flames blowing out the windows, but it’s too late.
With a bang the force of the flames pushes you from the ladder, you try and reach out for one of the rungs as you fall but your gloves slip from the speed and force of your falling body, and your helmet collides with the side of the aerial, your mind going blank as you fall helplessly onto the grass below, ignorant of the calls of your name and the sounds of rushing footsteps as you lose consciousness.
-
The next thing you hear is an annoying beep, at first you think it’s your PASS alarm but it’s not that annoying. You groan, your head clouded in fog with your body feeling heavy, sore.
There’s a movement by your side, and you decide to blink open weary eyes to find out what it is. Your eyes meet your big brother’s worried ones, and you smile weakly, still feeling weird from the sedation you’d been under. You were very much aware of the fact you had ended up at Med. Again.
“Mnh, hey.” You murmur. You realise now the weight on your other side was your arm in a sling, your knee was strapped up pretty good and you were sure you could feel stitches on your neck going down into your shoulder.
“Hey, kiddo,” Kelly murmurs, stroking your hair, mindful of the stitches just under your hairline.
“Guess I should have taken the aerial rather than just the air, huh?” You quip, a dopey smile from your own joke.
Kelly half-smiles, still looking so morose and only partially relieved. “I would have preferred that yeah. Instead of being scared that my sister had just broken everything in her body. You got so lucky, Y/N.”
“Feels it, I expected worse…” You sigh. “I’m sorry, Kel.”
Your brother shakes his head, “No, no more apologising from you. You’ve done nothing wrong, and all I’ve done is be an asshole to you.”
His lip quivers, grasping at your hand gently as he feels the tears fall silently.
“Hey, I’m here. Why are you crying?” You rub your thumb across his knuckles, worried at what had him so upset.
“Because you’ve done nothing but support me, and I let practically a stranger almost ruin all of that, take my sister away and have her maybe never know how much I love her.”
Your eyes well up now, all that restrained emotion coming to the surface, and your lip trembles too. Relieved that he had seemingly come to his senses in believing you.
“Kel, it’s alright, you’re here and-”
Kelly’s phone rings. He ignores it and you nudge him. “Hey, answer, it could be work or something. I can’t exactly run away.” You grin, he shakes his head with a sad smile.
As his eyes clock the name on the ID, his face darkens and you frown, you think you can guess who’s on the other end.
He answers, putting the phone on speaker. “Severide.” Voice clipped, in no mood for politeness.
“Kel, are you on your way, the reservation’s at 8pm, you know how many strings I had to pull to get us a spot?” Olivia thinks she’s good at putting on an innocent enquiring tone, but all Kelly can hear now is the controlling and demanding woman that was in front of him all along.
“I’m not on my way, I’m at the hospital with Y/N, she had an accident at work today. I’m gonna be with her overnight and then I’ll be taking her home tomorrow as well.”
There’s silence on the line, you can feel Olivia’s irritation through the phone and it makes you roll your eyes. Kelly’s jaw is set tight.
“Kel, really? She can’t be in the hospital for one fucking night on her own? This restaurant doesn’t take kindly to cancellations, not when I called in favours. You have to stop babying-”
Your eyebrows go up at the unmasking of her feelings, and you watch in pure satisfaction as Kelly cuts her off.
“Olivia, I’m going to say this once. We’re done. Take your restaurant and shove it, we won’t be seeing each other again. Lose my number.” With that, Kelly disconnects the call, flicking around in the phone app to block the number. Letting out the biggest of sighs as he looks at you, you try not to smile because you still understand it’s hard to lose what you thought was a good connection, but at the same time, you’re elated that you have your brother alert and seeing that you’d never get in the way of what he wanted.
“Remind me to never lose my mind and believe some witch over my own sister again.”
“Oh don’t you worry, Kel, we’re not doing this again, if there’s a next time the gloves come off and I kick either your or your new lover’s ass.”

Requested by Anon: Hi 😊 as i love your imagines, i also dare to send one in. Maybe a Kelly Severide one where he and his sister had a great relationship earlier but meanwhile they barely talk or just fight. One day there's a huge fire at an office building and CFD gets called. Kelly then finds out his sis is in there and immediately searches her. She's unconscious and took some damage but at the Med he stays with her an later he promises her no more fights and that he'll be there for her like he was before. Hope that does not sound too weird 😅
A/N: I realised about halfway through this fic that Peter Mills would have been on Squad around this time, but I love Joe too much to take him out, so sorry Pete, but Joe's on Squad for this fic.

You glanced at your phone for the 10th time in an hour, sighing when the screen had nothing to offer except a two-for-one offer on pizza, a weather alert and a reminder of an upcoming bill. You stayed looking at the wallpaper for a moment, it was a photo of you and your brother on your most recent camping trip with Matt Casey; a rare moment where the two firefighters could get the same furlough lined up. The three of you were bundled up beyond recognition in the cold snowy mountains of Colorado, but with the brightest smiles on your faces.
You sigh, putting your phone down, begrudgingly going back to what your computer screen was demanding of you. Being at work in the aftermath of an argument with Kelly was never fun, especially if he was on duty. It meant waiting almost two days before you could see him face to face and resolve whatever you’d fallen out over.
Falling out with him wasn’t at all usual, and when it did happen it happened in an explosive fashion, taking a while for the tension to dissipate. It was mostly about being too protective of each other, sometimes you found yourselves arguing over the family or decisions the other sibling was making - and though it was meant with love, it could sometimes be too much for the other.
Growing up in a household where your dad was either cheating, avoiding the family or drinking, and where your mom was trying her best to just stay afloat, often required you and Kelly to become your own two-person family unit. And you did, the both of you found comfort in that, always looking out for each other and encouraging each other.
This time around it had been you who had caused the problem, you had tried to tactfully suggest that Kelly be wary of his old flame, Renee. Renee had seemed okay enough until she didn’t. Suddenly returning to Chicago and bringing a pregnancy to Kelly’s doorstep was all a bit suspicious to you - the timing hadn’t added up at all, and after asking Shay a few questions about the logistics and whether it would be physically possible, you only grew more dubious. Feeling sure of your suspicion, you had broached the subject with your brother.
Objectively you knew Kelly would react exactly as he had, nobody likes to be told that they might be being made a fool of, but it still stung that Kelly got angry at you and seemingly protected Renee instead.
You then found yourself crying in your car in the parking lot outside his apartment, having left your brother standing in his kitchen simmering with anger, you were absolutely frustrated and hurt that he had so sharply dismissed your concerns.
Now you could only play the waiting game, using Shay as a feeler for whether things had cooled down or not. You were under no doubt that she probably gave Kelly a piece of her mind too, and probably could have handled whatever he threw back a lot better than you could sometimes.
Staring at an email for two minutes more before deciding you needed a quick coffee and fresh air break, you put your computer to its idling screen and stand, stretching in the process as you eye everybody else in their little units. Many were engrossed in whatever business they were attending to - or whatever leisurely activity they were secretly trying to get away with.
Making eye contact with one of your colleagues, your friend Maisie, you give her an exaggerated yawn and a mime of asking if she wanted another coffee - to which she nodded and put her hands together in prayer, silently thanking you. You held out your hand in a show of five, telling her you’d be five minutes as you headed towards the elevator to head to the cafeteria floor.
Blinking away the tiredness and rolling out the tension in your neck some more, you watch as the numbers tick down to the floor you had requested. Just as the elevator should have dinged on the cafeteria floor the car came to a sudden, groaning, halt. The motion wobbles you on your feet, forcing you to snatch out a hand to grab the handrail to steady yourself. Heart thundering wildly you tried to take a second, to process what had just happened.
In the quiet of your surprised panting breaths, the lights splutter on and off, you close your eyes willing the electrics to hold out as the elevator car still bounces slightly from the abrupt stopping of momentum. Then, it’s darkness. A red security light blinks on and leaves you in an ominous dark glow, barely able to make out the panel in front of you. Luckily, you had slipped on your coat before leaving your floor, which meant your phone was in one of the deep pockets. Fishing it out you illuminate the screen and then turn on the torch, shining it on the panel so you can make sure it is the emergency ‘call’ button you're pressing rapidly.
You press three, four, times and are met with a static-y silence, you groan in frustration.
“Shouldn’t somebody be there to answer the damn thing?” You grumble to yourself, eyeing your phone and its “No signal” icon with disdain. That was your backup option out of the question.
Minutes go by and you don’t hear much of anything, only the ominous creaking groan of the metal box you were sealed in. Deciding to shed your jacket as you begin to feel quite warm in the confined space, wondering whether anybody knew of your predicament. How long would it be before Maisie questioned your absence?
As you gently fold your jacket over the handrail you jump out of your skin when you hear the blaring whine of the fire alarm, and the hairs on the back of your neck stand on end. Your heart pounds firmly against your chest, limbs tingling with anxiety.
Exhaling as your stomach flops wildly, “Shit.”
You had discussed this kind of thing with your brother before, but it was one thing to hear about a scary scenario than actually find yourself in it. Alone.
You take a second to gather your thoughts, gripping your phone tight as you try the call button again. And again.
There’s static for a minute or so more, then someone speaks, it’s static-y still but a voice nevertheless. Even more surprising to you, there were literally 100s of firefighters that could have been on the other end, but the voice was someone you knew.
“This is the Chicago Fire Department, do you know what floor you are on, is there anybody who needs medical attention?”
“Mouch? It’s Y/N Severide! I’m between the 9th and 6th floor, I’m not sure how far down I’ve got! I'm alone, uninjured, just ready to crap myself.”
“Y/N? Oh hell… Okay, it’s alright. We’re all here, you brother’s waiting for my info, I’ll tell him, alright? Just stay calm, I’ll be here the whole time. Just gimme a second.”
“O-okay, Mouch. I’m so glad it’s you.”
“Me too, kiddo. Me too.”
You could imagine poor Mouch's expression, perhaps even him making a panicked gesture of him telling you to hang tight as though you could see him. It gives you comfort to know that people who you considered to be family were there for you, the most reassuring thing however was knowing Kelly was literally the one coming to get you.
You stand pacing slightly back and forth, waiting to hear Mouch’s voice again. Or better yet the sound of Squad 3 trying to work through the opening and into the elevator itself.
“Y/N, Mouch again. Squad 3 are on their way to you, don’t touch any of the elevator walls, the fire is coming up from the basement. I repeat, the heat is rising, keep away from any of the metal surfaces.”
“Okay, Mouch, copy that.” You try and even out your breathing, not wanting to psyche yourself up into a panic about the confined space or the evergrowing heat. You keep yourself dead centre standing on the rubberised floor, snatching your jacket back off of the handrail so you could use it for protection if needed.
[Outside the elevator shaft doors on the 8th Level]
Kelly already knew there wasn’t anyone or anything stopping him from getting to you, the second he heard the address for the call his heart and stomach plummeted. On any given day he’d have had this reaction, but he felt the twinge in his gut even more considering how things had been left between you both.
Truck 81 and Engine 51 had remained further down to tackle the origin of the fire, some construction materials on the lower floors had been accidentally ignited. The older lining of the walls and the ceilings had acted as a tinder box, hurrying along the flames to some of the upper floors, with flames still attempting to rise.
Joe turned the drop key to open up the hoistway doors to reveal the shaft, all four men of Squad 3 winced at the blast of heat coming up from the shaft. Putting their SCBA’s on they suited up, Kelly was harnessed whilst Capp and Tony ensured he was securely held by the ram attached between the hoistway opening. Kelly starts with a preliminary look, immediately recognising that you had, in fact, got stuck between the 6th and 7th floor. He attaches a C-collar to his belt, a precaution he felt compelled to take as the fire continued to climb.
Joe radios Mouch, “Mouch, we got eyes on the car, we’re lowering down from the 8th to the 7th, Severide is on his way down to Y/N.”
“Copy that, Joe. I’ve got eyes on the others, the fire is coming up on the 5th, and the East stairwell is still free for you to exit.”
“Got it, Mouch. We’ll let you know when we got her.”
“Copy.”
The radio crackles into silence, Kelly turns his back to the elevator shaft so he can begin repelling down to you, slow steady pushes of his boots against the walls as he eases himself down towards the top of the car.
With every push it gets darker, only the light on his helmet to guide his way, the smoke had begun to reach up past the elevator car now, shrouding the shaft in thick smoke. He knew he had to get to you fast, there was only a certain amount of ventilation and, therefore, oxygen available to you. Kelly would never let fear cloud his focus on his work, but the sense of urgency only thrummed stronger knowing it was his little sister in there.
[Back in the elevator]
"Y/N, Kelly can see you, he's coming, sweetheart. How you holding up?" Mouch is back, and you feel tears sting at your eyes, you had been doing your best to remain stoic in the face of danger, but hearing Mouch connected you back to your reality.
You knew that by all standards your rescue was actually going quite quickly when the alternate option was being left to suffocate, yet that still didn’t stop the anxiety from seeping into your veins, the adrenaline pulsed wildly through you as the smoke began to push in thicker bursts through the vents of the elevator car.
"I know, it's gonna get tough in there, kiddo. But he's almost there, you just hang on, I'll be right here."
"Thanks, Mouch." You say it so quietly you're surprised when you even get a response.
"No need to thank me, Y/N. Just keep low, keep covered, let your brother do the work until he can instruct you."
"Will do." You coughed, the smoke was invading your breathing comfort now. At first, a few splutters, until it turns into a more steady rhythm of your body rejecting the foul air.
It had been drilled into your brain that you should never try and climb through the elevator hatch by yourself, and besides, it was unlikely you would be able to reach if you wanted to, but as the acrid smog continued to fill the confined space your brain was fighting against the urge to try and climb up and out anyway.
You were staying low to the ground with your jacket shielding your head and face, but the more you tried to recover your breathing the worse it got. Each inhale seemed to add weight inside your rib cage, lungs starting to burn as you could actually hear the roar of the fire beginning to eat the materials below your elevator car.
Loud, shuddering, clunks were coming from beneath and you started to feel the car vibrate, a high-pitched whipping sound could be heard and suddenly you were tilting violently to the right, the outer wall of the car hitting the inner wall of the shaft itself.
The momentum catches you off guard, sending you sliding into the side of the hot metal head first, almost bouncing off as you fall back and to your side, unconscious.
The sound of Mouch's frantic calls out to you and the sound of urgent radio chatter above your head are oblivious to you, blood drips from the gash in your head, your face covered in the blackness of the smoke.
You don't move.
[On top of the elevator car]
Kelly had been brought to a swift stop by Joe and Tony up above, the all-too-familiar sound of one of the elevator car’s support cables snapping had your brother’s team, rightly so, fearing for their lieutenant’s life. Once the commotion had died down Kelly was left gripping to a beam trying to recollect his thoughts, looking down at the car now listing to one side with you inside it.
“Severide!” Joe’s voice hollered across the radiowaves, concerned for your brother's wellbeing.
Kelly exhales sharply, pushing his feet back up against the sides of the shaft, ready to keep repelling. “I’m fine, I’m still secure, no signs of further deterioration. Come on, we’re running out of time, keep me going!”
Without resistance or protestation, Joe and Tony kept lowering Kelly to you, slowing down as his feet came into contact with the top, in the background Capp could be heard relaying information to Chief Boden.
Once he had got his bearings, Kelly gave the signal that he was securely on board the car. The rest of the Squad guys at the top waited with bated breath as Kelly set to work on opening the elevator hatch.
The sight that greeted your brother was hazy but still distinguishable, your prone form lay still in the layer of smoke that hung over you, his eyes change from worry to focus, keying his radio immediately.
“Capp, how much longer have we got?”
“Chief says 7 minutes, Severide, no more no less.”
Kelly doesn’t acknowledge that particular information, simply using the time he has to order that a stokes basket be lowered and that Joe also come down to assist.
“The car and the remaining cables can hold us both, Cruz, but we gotta move quick, she’s not conscious, possible head and spinal injury, we need to secure her and get the hell out of here.”
“Copy that, Severide. On my way with the stokes basket.” Kelly takes calming breaths inside his mask, focusing on the next task, instantly leaving Joe who's lowering from behind, as he climbs into the elevator to get to you.
Touching his boots to the elevator floor he feels the surface protest under his weight, which he promptly disregards as he moves down low to assess you. Taking a glove off he feels for your pulse, utterly relieved when he feels it there, sluggish but there.
Unhooking the C-collar from his belt he secures you in it, at least reassuring himself he was working towards your rescue as he waits for Joe and the basket.
With a firm rub of the heel of his hand against your sternum, he calls your name, imploring you to respond to the stimuli. He’s met with stillness, the gash is oozing slowly now, highlighting a swollen lump at the side of your head. It’s a sight that releases queasiness into his gut, another emotion to be ignored, knowing he had no room for familial concern right now.
There’s a thunk above Kelly’s head, moments later the front end of the stokes basket appears as Joe lowers it in. The elevator continues to growl at the added weight, Kelly could do nothing but pray the flames didn’t take any more of the cables until the three of you were free.
Kelly slides the basket next to you, rolling you onto the basket as he instantly begins securing the various straps into their crisscrossed positions, he had to make absolutely certain you were secure before being lifted up and out of the confined space.
“I got you, kiddo. I’m here, I love you and I’m sorry, so please hold on for me so you can chew me out for being a defensive asshole.” He murmurs as he works, hands moving on autopilot as Joe gives him a 3-minute warning.
The final knots are tired and your feet are secured, chest strapped and thighs banded across, neck and head fixed into place. Satisfied you wouldn’t be going anywhere Kelly starts to tilt the basket with you in it, leaning it up and vertical so that Joe can start to guide you to be lifted towards Capp and Tony.
Watching you disappear through the hatch, Kelly moves underneath it to grab onto Joe’s hands, the winch could have lifted Kelly alone but time was of the essence and it was faster for Joe to at least hoist him out of the dangerous metal box threatening to free fall at any moment.
Joe and Kelly stand in anticipation as they watch you in the basket rise up the two floors to Capp and Tony and witness the two men carefully pulling you into the open hoistway space and into the building.
It’s Capp over the radio, “Severide, Cruz… 81 came to get Y/N, time for us to go, are you secure?”
“We’re secure, Capp. Bring us up!”
The winch seems to take forever, and Kelly mentally notes that he and Joe will have to move with a rocket up their ass lest they get themselves into a pickle. Hearing the raucous sounds of materials perishing to the ferociousness of the flames below. Kelly is itching to get onto solid ground and get outside to you as soon as possible.
In true Squad 3 fashion it's just about the time Tony and Capp pull your brother and Cruz into the main part of the building that they hear several ear-splitting whips and cracks of the other cables snapping under the pressure of the flames; the four men disconnect their harnasses and push each other forward and out of the way of any stray flying cables, stumbling forward as they head towards the exit stairwell.
-
Kelly can start to hear the Chief over his radio as he descends to freedom, he had already known they were working on borrowed time and if it weren’t for him worrying for his fellow Squad members, he wouldn’t have worried at all - knowing you were safe would have been enough.
Ensuring Tony, Capp and Joe were out Kelly follows suit, blinking into the sunlight as he practically rips off his mask, he eyes Chief with an apologetic look, the older man simply holds up a hand, as if to say “I know.”
Kelly’s eyes are frantically looking around for the Ambo that had you, and Boden whistles, nodding in the direction of Ambo 61 where Gabby and Shay were by your side, seeing to your injuries.
Your brother takes off, shedding his jacket and handing it to Casey who is standing in wait for him. Kelly looks from your sooty face beneath the oxygen mask where Gabby is squeezing the bag, to Shay, then to Casey and then back to you again.
It's Gabby who speaks up first, eyes focused on you but relaying the details, "She's stable, Kelly. Just took in too much smoke and got a pretty nasty knock to the head. We're gonna get her to Med, they'll probably keep her overnight, maybe more depending on the tests and scans."
"She'll be alright, Kel. She's a fighter like her annoying big brother." Shay wraps an arm around him, and Kelly lets out a choked laugh, his eyes filling with tears. He could have lost you in so many different ways today, and it would have all been left with you thinking he was mad at you.
"Case, you got her out?" Kelly asks,
Matt nods, "Of course, Sev. Couldn't let you Squad guys do all the work, you already complain enough as it is." Matt grins, brushing off the grateful look Kelly was giving him. It was nothing to come and get you, it was their job and you were like a sibling to all of them as well.
Kelly moves forward, wrapping Matt in a squeezing hug, feeling his fellow Lieutenant pat his back.
"Hey, go on, I got this-" Matt holds up Kelly's turnout coat. "You go with them to Med, we'll be there in a bit."
Kelly nods, "Thanks, man. Really." Matt simply shoos him away with a smile, leaning forward to give your leg a squeeze.
"Wake up for us, kiddo."
Gabby nods at Shay who helps get you into the back of the vehicle, Kelly climbs in after you and Gabby, being sure to stay out of the way. The doors slamming shut almost make him jump, the anxiety returning as he watches Gabby continue to supply your oxygen.
Shay starts the Ambo and with blaring sirens, they're carrying you to Med.
-
Kelly was made to wait in the family room for a good few hours whilst you had tests done both for your head injury and the smoke inhalation. Will Halstead had come back periodically to personally reassure your brother that what he had seen so far was promising, but they would be keeping you for a few days to make sure nothing more sinister developed.
In that time the rest of the firehouse had been and gone once they knew you were most likely out of the woods, with many of them promising to come back tomorrow to check in with the Severide siblings.
Now, Kelly sits by your bed, waiting for you to wake up again. You had regained consciousness not long into your arrival at Med, but you had already been whisked off for scans by that point. Your current sleeping state was just that, sleeping, given that your ordeal had been quite the draining afternoon.
Your big brother runs a hand through your hair, simply watching you like a hawk as if you’d disappear right in front of him.
Lost in thought and guilt about your argument he doesn’t even realise your eyes are now half-open, drowsy but coming back to reality.
“Are you staring at me, weirdo?” You croak, even half-awake you have the ability to tease your brother, and it makes him scoff with laughter immediately, relieved butterflies tumbling in his stomach.
“I gotta make sure you don’t go off and get yourself stuck again.” He poked back, smiling brightly now. “God, I’m so glad you’re okay, sunshine.”
Your own heart hammered at the mention of being “stuck”, the darkness, the smoke, the closing in of metal walls, and the loud creaks, groans and clunks flashed across your mind. Kelly saw your expression darken and leaned forward, giving your hand a squeeze.
Your eyes close, taking a breath as you squeeze Kelly’s hand back in return, he had always been good at helping you with panic attacks and general anxiety.
“Take it slow, okay? Deep breath in…1, 2, 3… deep breath out.” He encourages you, giving you a moment when the breathing invokes a few deep hacks of coughing from you. He keeps a steadying hand on you, gently offering you a cup of water to sip at after the hacking subsides. You lick your lips, smiling thankfully.
“I’m so glad it was you, Kel. I’m glad it was 51.” You sigh, keeping your breathing as steady as possible, feeling a little better as Kelly rubs your back, just as he would when you’d had a nightmare as a kid.
“Me too, Y/N. I can’t even begin to think… the way I left things the other day…” Kelly’s face is pained, you can tell he feels supremely guilty about what happened.
Your expression softens, given everything that had gone down, you were simply relieved to have a life and a brother still. “Kelly, it’s okay, I get it-”
“No, it isn’t. You were right, Y/N. I confronted Renee, and she spilt the truth. You and Shay were right, and I was an asshole to think you had anything other than my best interests at heart.” He cups your cheek, knocking his forehead with yours.
“We’re a team, you and me, kid. I trust you with anything, and I should have trusted you with that.”
Silent tears escape you now, feeling so relieved that he wasn’t mad and that you didn’t have this tension between each other anymore.
“Team Severide, woo woo.” You whisper with a smile, wrapping your arms around your brother’s neck as you tuck your face into his shoulder. He holds you close, sighing, chuckling quietly too.
“Team Severide is right, kid.” You leaned back, grinning tiredly at your brother, you should have been annoyed that you were literally a grown adult and he still called you “kid” or “kiddo”, but really it never bothered you, it made you feel safe and connected to him like you always had been.
“So, does this mean I can have a sibling servant for a few days whilst I recuperate?” You ask with a picture of innocence on your face.
Kelly rolls his eyes but nods, still smiling, “Sure does, Chief has already cleared a few days for me, so make the most of this rare occurrence.”
You snort, squeezing your brother’s arm with a mischievous look, patting his face in a playful slap. “Oh, I will, brother. I will.”
A snippet from my upcoming Severide!Sister fic. Kelly has a new girlfriend and Severide!Sister is struggling to get on board:
Kelly had left you and Olivia to make small talk, and you had decided that perhaps you had caught her at a bad spot outside the bathroom earlier, choosing to hope that the person you’d been talking to all night was the genuinely kind and interested person she seemed to be.
“I’ve really enjoyed this tonight, Olivia. It’s so good to see Kelly happy and excited about things other than work.” You smile, sipping at your drink, waiting for some kind of response.
You were trying to reconcile yourself with the fact that she must have been caught off guard by you colliding with her, you were willing to give her the benefit of the doubt.
Olivia simply stares at you, an arrogant smirk on her face, she raises an eyebrow.
“You think this is for you? To enjoy tonight? I’m here because your brother wanted me to be, don’t get it twisted. We’re not going to become best friends or fun sisters-in-law or whatever. Kelly’s got a right to have a life away from his little sister hanging off of him at every moment, don’t you think?”
The words cut into you and you feel your body turn cold, she’s still got a smile on her face for anybody that might look over to the table and see whether Kelly’s sister and his new girlfriend are getting along. You feel the rage bubbling up in your chest, jaw clenched, you really didn’t understand what this woman’s problem was.
“I didn’t… I’m sorry what have I done to offend you? Earlier was an accident, and I know Kelly has his own life, I would never-” The sound of her grating laughter cuts through the air, and you have no idea what’s going on until you feel Kelly return beside you.
“Kel, Y/N was just telling me stories from when you were kids.” She grins, giving him the doe eyes as you sit dumbfounded.
“Is that so, huh? Nothing too embarrassing, I hope.” Kelly turns to you, and you realise you’re frozen in incredulity. Seconds pass by, and your brain kicks back in, shoving out your best half-hearted laugh and smile. “Nothing too embarrassing, just the important bits.” You jest, but really you just want to throw the rest of your drink in Olivia’s face.
