Agent Y/N Hotchner

Summary: Y/N Hotchner (Aaron Hotchner’s younger sibling) joined the team six months ago, after Aaron's retirement, Y/N found interest in the team when they got their hands on an old case file. Signing up for training, Y/N underestimated the responsibility of being on the BAU team.

The warehouse smelled of oil and rust, the air thick with dust that settled on their skin like a second layer. JJ, Tara, and Y/N Hotchner had been searching for an escape route when the unsub, an unhinged, paranoid survivalist, had slammed a metal door shut behind them, locking them inside.

"Shit," JJ hissed, immediately reaching for her radio, but all they got was static. The unsub must’ve jammed the signal.

"We need to find another way out," Tara said, scanning the room. The only exit was the locked door and a boarded-up window near the ceiling. "If we stay put, he might come back, but if we make noise, he might just—" Before she could finish, Y/N spotted movement from the shadows. The unsub lunged.

Instinct took over. Y/N moved fast, trying to dodge his attack, but he was bigger, stronger, and caught them by the arm, yanking them off balance. She twisted in his grip, but the force sent them crashing to the ground, their left shoulder slamming against the concrete at a terrible angle.

A sharp, white-hot pain shot through their body. Y/N let out a rough, broken scream, their breath catching as agony swallowed them whole.

"Y/N!" JJ and Tara’s voices overlapped, their footsteps rushing toward them.

The unsub took a step back, breathing heavily, but instead of running, he sneered down at Y/N. "Should've stayed down, girl." JJ didn’t hesitate.

One shot.

The crack of the gunshot echoed in the warehouse as the bullet tore into the unsub’s chest. He staggered, eyes widening in shock before crumpling to the ground. JJ kept her gun raised, breathing heavy, her jaw tight. "You okay?" she asked Tara without looking away from the unmoving body.

Tara was already at Y/N’s side, pressing a steadying hand against their uninjured shoulder. "Y/N, talk to me," she urged, voice calm but firm. Y/N panted through the pain, their body curling in on itself. "Shoulder—" she rasped. "It’s—"

"Dislocated," Tara finished for them, carefully running a hand over the injury. Y/N flinched violently, a strangled noise escaping their throat.

JJ slowly approached the unsub, toeing his gun away before kneeling down to check his pulse. Two fingers pressed against his neck, waiting, nothing. She exhaled sharply, eyes dark. "He's dead." Without another glance, she turned back to Y/N. Y/N groaned, their body shifting slightly, sending a fresh wave of pain searing through their shoulder. "Fuck—"

"I know," JJ murmured, immediately kneeling beside them. She reached out, brushing damp strands of hair from Y/N’s forehead. "I know, sweetheart. Just breathe for me, okay?"

Tara stood, scanning the dimly lit warehouse. "We can’t just leave them like this. I need to find something to splint their shoulder, keep it stabilized." JJ nodded, her focus on Y/N as Tara moved through the space, rummaging through rusted shelves and discarded crates.

"J… hurts," Y/N whimpered, their breath coming in quick, shallow gasps. JJ’s fingers curled around Y/N’s good hand. "I know, honey. I know. But I’m right here. We’re gonna get you through this." JJ shifted slightly, allowing Y/N to lean against her chest.

She could feel the unsteady rise and fall of Y/N’s breathing, the tremors wracking their body. "Just focus on me, okay? What’s the first thing you’re gonna do when we get out of here?" Y/N exhaled shakily, their forehead pressing into JJ’s shoulder. "Shower… maybe s-sleep forever," she mumbled weakly.

JJ huffed a soft laugh. "Yeah? Sounds like a plan. I’ll even make you coffee in the morning."

"C-coffee…" Y/N breathed, the thought almost too far away to care about, but it still brought a small, appreciative smile to their lips. Tara returned a minute later, a wooden plank and some torn fabric in her hands. "This'll have to do until we can get them out of here."

JJ helped shift Y/N slightly, but even the smallest movement sent a sharp jolt of pain through their body. Y/N moaned low in their throat, eyes squeezing shut as their head fell back against JJ’s shoulder.

"You’re doing so good," JJ whispered, pressing her lips to Y/N’s temple. "Just a little longer, okay?" Tara worked quickly, binding Y/N’s arm as gently as she could. "It’s not perfect, but it’ll keep it stable." She met Y/N’s pain-glazed eyes. "You hanging in there?"

Y/N gave a small, tired nod. "Barely." JJ adjusted her hold on Y/N, wrapping an arm around their back to support them. "I’ve got you," she murmured. The minutes stretched into an eternity. JJ and Tara kept talking to them, keeping them awake.

JJ rubbed slow, comforting circles into their back, whispering soft reassurances. Tara kept checking their pulse, making sure she wasn’t slipping too far into the pain. "You’re a tough one, Hotchner," Tara mused, her tone light despite the tension. Y/N huffed a weak chuckle. "Runs in the family."

"Yeah, I know." Tara kept a careful eye on Y/N as her voice softened. "You’re gonna be okay. We just gotta keep you talking, all right? Let’s take your mind off the pain." Y/N nodded, their throat tight. "I don’t know if I can."

"Yes, you can," JJ insisted, brushing her hand over Y/N’s damp forehead. "You’ve got this, just talk to us. Tara, make them talk. Anything." Tara raised her brows, a playful glint in her eyes. "Okay, okay. Fine, let’s see… You ever think about going skydiving, Hotchner?" Y/N let out a weak breath. "Skydiving? Are you crazy?"

Tara grinned. "Well, you’ve gotta die somehow, right? Might as well be in a way that makes people say, ‘Man, they were brave.’" Y/N laughed weakly, but it was enough to draw out another strained but genuine smile. "I’m more of a stay-on-the-ground kind of person."

JJ smiled, continuing her gentle ministrations. "You and me both." The sound of approaching sirens finally broke the silence. JJ exhaled in relief, her grip tightening around Y/N.

"They’re here," she whispered. Y/N let out a shaky breath, their body trembling against JJ. "You did good, kid," JJ murmured, pressing a soft kiss to their hair. "You did real good."

The warehouse door was kicked open, a burst of voices flooding inside. "FBI! Hands where we can see them!" Emily’s voice. Tara stood immediately, signaling to the team. "We’re clear! Unsub’s down... Y/N’s hurt!"

Boots pounded against the concrete floor as their team rushed in, led by Emily, Luke, and Rossi. Emily’s eyes swept the room, landing on JJ and Y/N, her expression shifting from hardened focus to sharp concern.

JJ barely looked up. "She needs a medic... now." Emily knelt beside them, her hand grazing Y/N’s uninjured arm. "Hey, kid," she said gently. Y/N groaned in response, their head rolling weakly against JJ’s shoulder.

"She needs help Em," JJ murmured. "She’s exhausted." The paramedics arrived next, their med bags already unzipped. "What are we looking at?"

"Left shoulder dislocation," Tara answered, stepping back to give them space. "She took a hard fall." One of the medics knelt, assessing Y/N’s arm with careful hands. "We’ll get them on a stretcher, stabilize the joint, and give them something for the pain."

Y/N whimpered when they moved them. JJ ran a soothing hand over their hair. "I got you," she whispered. "Just breathe, sweetheart." Emily’s gaze flicked to JJ, catching the rare softness in her eyes. She knew JJ cared about Y/N, hell, they all did, but this? This was different.

JJ had spent an hour holding Y/N together, keeping them from breaking under the pain. That kind of care wasn’t just professional. It was personal. The medics got Y/N secured, an oxygen mask over their nose, an IV slipping into their arm to deliver pain relief. The tension in their body finally started to ease.

JJ stood, hesitating for only a second before squeezing Y/N’s fingers once more. "I’ll be right behind you, okay?" Y/N’s eyelids fluttered, a ghost of a nod. As the stretcher rolled out, Emily turned to JJ. "You okay?" JJ let out a breath, her eyes trailing after Y/N. "I will be."

Emily studied her for a beat before nodding. "Let’s get them to the hospital."

The hospital room was bright, too bright, the overhead lights casting a sterile glow over the pale blue walls. Y/N lay on the exam table, their body finally beginning to relax as the drugs coursed through their system.

JJ stood beside them, one hand wrapped around Y/N’s as the doctors and nurses moved efficiently around them, preparing to reset their shoulder. "You’re doing great, kid," JJ murmured, her thumb tracing small circles against Y/N’s skin. "Just a little longer."

Y/N blinked slowly, their pupils dilated, their lips parting as if she wanted to say something but couldn’t quite find the words. "Alright," the doctor announced, positioning himself at Y/N’s side. "We’re gonna get that shoulder back in place. You might feel some pressure."

Y/N let out a breath, their gaze flicking up to JJ, "Stay?" JJ’s heart clenched. "I’m not going anywhere," she promised. The doctor nodded at the nurse, who adjusted the IV drip, pumping more painkillers into Y/N’s system.

JJ could see the drugs taking hold, the tension in Y/N’s muscles easing, their expression softening, their blinks growing slower. The doctor gave JJ a small look of warning before he took hold of Y/N’s arm, rotating it gently. Y/N whimpered, a small, pained sound escaping their lips, their fingers weakly squeezing JJ’s hand.

JJ leaned closer. "I know, sweetheart. Almost done."

A swift movement, a deep pop...

And then it was over.

Y/N let out a slow exhale, blinking up at JJ with glassy eyes. "Did you see that?" she mumbled, voice slurring. "My arm just—boom—" she wiggled their fingers lazily, "back in place." JJ bit back a smile, brushing her thumb across Y/N’s knuckles. "Yeah, I saw."

Y/N grinned, slow and sleepy, "I feel great. I love drugs. I should dislocate stuff more often." JJ snorted, "Let’s not make a habit of that, okay?" Y/N just giggled, their head lolling slightly to the side. "You're so pretty."

JJ huffed a quiet laugh. "You’re definitely high."

"Maybe," Y/N mumbled, their voice barely above a whisper. "But you’re still pretty." JJ shook her head, smiling as she brushed a damp strand of hair from Y/N’s forehead.

The door burst open seconds later, and the rest of the team rushed in. Rossi, Tara, Luke, and Emily all crowded around the bed, their faces a mix of concern and relief. "How’s she doing?" Emily asked, her sharp eyes immediately scanning Y/N’s face.

JJ smirked. "She’s high as hell." Y/N blinked sluggishly at the new arrivals, their face lighting up when she spotted Emily. "Boss lady!" she greeted with a bright, dopey grin. Emily arched an eyebrow. "That’s me." Y/N nodded sagely, squeezing JJ’s hand. "Did you know… that JJ is so pretty?"

JJ sighed. "Oh god, we’re back to this." Luke grinned. "I like high Y/N. She’s affectionate." Y/N’s head lolled toward him. "Luuuuke," she drawled. "You’re so... so... tall." He chuckled. "Can’t argue with that." Rossi stepped closer, his hands tucked into his pockets. "How’s the shoulder, kid?"

Y/N stared at him for a long moment before whispering, as if revealing a great secret, "Attached." The whole team laughed. Even Rossi let out an amused chuckle, shaking his head. "That’s good," Tara said, amused. "Let’s keep it that way."

Y/N nodded solemnly before their eyes drifted down to where JJ’s hand was still in theirs. She patted it clumsily. "This... is my emotional support JJ." JJ groaned, but the team lost it, laughter echoing through the small hospital room.

"You’re not wrong," Emily said, shooting JJ a teasing glance. Y/N sighed dramatically, leaning their head back against the pillows. "I love you guys." Tara chuckled. "You’re gonna regret saying that when you sober up." Y/N’s face scrunched up.

"Nope. I mean it. You’re all my bestest friends." She turned to Emily, their eyes shining with exaggerated sincerity. "Even you, boss lady. Even though you’re scary sometimes." Emily smirked. "That’s fair." Luke shook his head, grinning. "I should record this."

Y/N gasped. "Nooo." She clutched JJ’s hand dramatically. "JJ, protect me!" JJ rolled her eyes but gave Y/N’s hand a reassuring squeeze. "Alright, alright. No recordings." Y/N exhaled in relief before their gaze landed on Tara. "Taraaa," she drawled. "You were so cool back there. Like a doctor. You should be a doctor."

Tara laughed. "I’ll consider it." Y/N nodded. "Good. You’d be great." Rossi smirked. "I think the painkillers are wearing off." Y/N pouted. "Nooo. I like being floaty." Emily shook her head, amusement twinkling in her eyes. "You’re gonna hate yourself in the morning."

Y/N groaned, already feeling the first hints of exhaustion creeping in. "Ugh. Future me’s problem." JJ smiled softly, brushing her thumb over Y/N’s knuckles. "Alright, enough excitement. You need to rest."

Y/N sighed but nodded, their eyelids already drooping. "Okay. But only 'cause you said so, emotional support JJ."

The team chuckled again, the weight of the day finally beginning to ease as Y/N drifted off to sleep, still holding onto JJ’s hand.
