A/N: This is for a prompt I got from my IRL friend, TheChiaroscuro, who said, "The BAU are after an Un-sub who's been targeting blondes, and as bait J.J. goes out to lure in the killer with Emily and Reid as her back-up." This came out much longer than I expected, and she really enjoyed it, so I'm publishing it! Enjoy!

Summary: JJ is sent undercover to a bar, with Reid and Emily as backup. Of course, nothing is going to happen, is it? Right, this is the BAU team we're talking about, people.

Warnings: Brief violence, implied rape and torture, very very small mention of drug use. Honestly, I don't know why I'm putting these warnings down, everything in this chapter is really mild, really.

Disclaimer: As always, I don't own Criminal Minds, which disappoints me. Although is I DID own the show, that means I'd have to write up plot-lines and such, which I would suck at. On the up side, I could meet the actors!

I've Got You're Back

"How did I get stuck doing this?" complained JJ, tugging at the rim of her sparkling red cocktail dress. "Why can't Reid do it?"

"Reid isn't blond enough," Emily soothed her friend patiently for the hundredth time, brushing a bit of eye-shadow over JJ's face with precise ease.

"Plus I'm not a female," piped up Reid, leaning on the wall across from them where he had been for a while, watching the conversation with interest.

"You sure about that, Pretty Boy?" Morgan joked, just walking into the room and catching the tail-end of their conversation. "You look pretty feminine to me; est tu gay?"

Emily and JJ both burst into noisy giggles. Reid, not missing a beat, fired back at his friend, "Says the man who calls me 'Pretty Boy.'" A dumbfounded expression took over Morgan's features and Emily and JJ howled even harder with laughter. "And it's êtes-vous gay."

"Touché, kid; touché," Morgan conceded in defeat, lifting his hands in surrender. Reid felt a small smile of victory tug at his lips and Emily gave him a secret thumbs-up Morgan thankfully didn't catch.

Hotch entered the room then, frowning slightly at the ruckus he found. Deciding he didn't want to know, he asked, "Are we ready to go?"

"Yep," Emily answered, carefully adjusting the last part of JJ's outfit. JJ gave a small gulp and tugged nervously at the hem of her dress, her fingers flitting over the silky fabric.

None of the profilers in the room missed this and Morgan asked somewhat cautiously, "JJ, you OK?"

"You don't have to do this if you don't want to," added Hotch gently, his face blank but his eyes betraying his concern for his young agent.

JJ let out a loud exhale through her mouth. "I'm good; let's do this."

Emily smiled lightly then said seriously, "Me and Reid will be there the entire time, OK? So don't worry, you'll be perfectly safe." The raven-haired woman gave her blond friend a quick hug, smiling again.

"Thanks," said JJ, somewhat gratefully. "And I trust you guys completely."

And that's how JJ found herself standing in the middle of a darkened club, the floor vibrating from the thumping music and the lights wildly spinning across the walls in diamond-shaped patterns. JJ jumped slightly when a voice came through her ear, breaking her out of her trance.

"JJ?" Morgan's voice called through her earpiece.

Cupping her hand casually over her ear, JJ said back, "I hear you."

Sounding satisfied, Morgan continued. "OK, we're looking for a vibrant, flirty man in his early thirties. He'll be drawing attention to himself, and is most likely attractive and charming. Do you see anyone like that?"

JJ scanned the group, glancing over all the idiot drunks spilling their drinks over their friends, sweaty people dancing on the main floor (some of them looked like they were having seizures, the dancing was that bad), a group of scantily dressed women giggling in one of the booths, until finally her eyes landed on a man sitting on a bar stool.

He was dressed casually but brightly, with blue jeans and a purple button-down shirt. His hair was sleek and tipped with baby-blue highlights, bringing out the colour in his eyes, and JJ could swear he was wearing some eye-liner, although it was impossible to tell from this distance. He was very attractive and was chatting up a pretty young girl that seemed enthralled with every word he said to her.

"Over by the bar," JJ told Morgan, "He could be our guy."

There was a moments silence from Morgan before he made a sound of agreement. "Yeah, he looks like the unsub. Act natural, and go up and talk to him."

"He's talking to another girl," JJ said, taking a deep breath.

"So, use your feminine charms to get his attention away from her and onto you. That's no too hard, is it?"

Rolling her eyes but not responding to Morgan, JJ made her way over to the bar, remembering when she was half-way there to sway her hips like Emily had told her to. She felt ridiculous doing it, but at least three men did a double-take as she passed them, so she figured her "feminine charms" were working.

She slid in between the girl and their possible unsub, cutting off what the girl was currently saying with a loud proclamation of, "What's a girl got to do to get a drink around here?"

Something lit up in the man's eyes as JJ pretended to ignore him, also ignoring the dirty looks she was receiving from the young girl. Technically, thought JJ, it was this girl's lucky day; if this man was their unsub, they had just saved her from being his next victim.

"Let me get that," the man said when the bartender slid a drink over to JJ.

JJ batted her eyelashes at him and purred as convincingly as possible, "Why, thank you very much."

The younger girl tried to get the man's attention back on her, but his eyes were now firmly fixed on JJ. Looking deflated, she stalked off, sending a vicious glare JJ's way. The blond agent almost flinched at that; she hated acting so rude, even if it was to catch a killer.

"Good, keep that up," Morgan couched through her ear. "Now that you've got your drink, take a few sips then excuse yourself to the bathroom; Reid and Prentiss will be watching to see if he puts anything in your drink."

JJ bit her lip to refrain herself from snapping at Morgan, telling him that she knew the plan and could take care of herself and would he stop treating her like a newbie agent. Instead, she ignored him and smiled at the man, stirring her drink slowly and not breaking contact with the man's fiery, greedy eyes.

"So, I haven't seen you around here before."

"I'm just visiting, looking for a good time," flirted JJ, taking a sip from her glass. Urgh, some sort of fruit mix; not her favourite alcoholic drink to have.

The man flashed a smile at her, his eyes watching her every move and subtly admiring the curves of her body. "Hmmm… I can give you that…" He leaned forward slightly and a cold chill raced through JJ, twisting her gut into a sick knot.

She quickly gave a sip of her drink, blocking the man from moving any closer to her, before she set her glass down and stood up. "Just let me run to the bathroom real quick, 'K?"

The man leaned back again, a predatory smirk taking over his features as he gave a nod. Suddenly, under the shadows of flickering lights, he didn't look very attractive.

Not even bothering to look behind herself, JJ walked as fast as she could to the bathroom without actually running. Bursting through the door, she was relieved to find it empty, except for a girl passed out in one of the back corners. JJ made a note to herself to make sure someone came in and got her; she didn't want the poor drunk girl to be taken advantage of just because she had had a little too much to drink.

Leaning against one of the sinks, JJ drew in a shaky breath, running a hand through her hair and trying to quell the queasy feelings coiling in her stomach. Her head jerked up when the door opened again, but she relaxed when she realized it was just Emily.

"You OK?" the black-haired woman asked, alarmed.

JJ waved a hand casually, straightening back up. "Yeah, I'm fine. Reid's watching him?"

"Like a hawk," clarified Emily, looking a tad more relaxed, and JJ gave her a tight-lipped smile.

"Good; guess I should go back in there, hah?" said JJ, feigning another unconcerned smile. In truth, the thought of seeing the man again made her heart jump and her stomach lurch uncomfortably.

"Yeah," Emily nodded. JJ moved to leave, but Emily grabbed her arm at the last moment. "Don't worry, OK, JJ?"

JJ lightly ripped her arm from her grip, brushing off the other agent's worried eyes with an unconvincing smile. "I'm fine, Emily."

Venturing back out into the bar, JJ swallowed nervously, her eyes locking on the man patiently waiting for her.

"He hasn't put anything in the drink."

JJ nodded slightly at the sound of Reid's voice coming through her earpiece. She scanned the crowds quickly and was able to pick out his lanky, awkward form farther back in a booth, casually watching the bar where the man sat.

"I don't think it's him," Morgan chimed in. "I think we have the wrong bar, guys."

"Are you sure?" questioned Reid, "I was almost positive he would turn up here…" The genius lapsed into silence, and Morgan gave a small sigh.

"Reid, relax. So you got one thing wrong for once, no big deal." Then addressing everyone else, Morgan said, "OK everyone, lets pack it up."

JJ could briefly hear Reid mumbling under his breath of how, "He was never wrong," when she noticed the man was approaching her again.

Morgan must have noticed as well because he said, "JJ, get rid of him, we're going."

JJ rolled her eyes to herself. "Yes, mom," she mocked. She heard the soft chuckle of Morgan in her ear before the man from the bar was suddenly in front of her. Still smiling from her team's antics, she directed it at the man, hoping it looked more sincere than she felt.

"You took a while," he pointed out, although he didn't look too offended; in fact, he smiled charmingly at her like she was a troublesome toddler.

"Yeah, sorry, someone just phoned me. I gotta go," she said, quickly coming up with an excuse. She was surprised when he just grinned again.

"OK, it was nice meeting you. Have a nice night." Then he turned and started back to the bar, not sparing her a second glance.

JJ shook her head for a moment, trying to drive out the foggy thoughts that invaded her mind. Definitely not our guy, she thought, wandering towards the back door the team had agreed they'd use to exit. However, as soon as she had exited into the alleyway, she knew she had made a mistake.

Every one of her senses lit up in flames that had developed over the years she had worked with the FBI, and she took an instant step back, bumping back into the door she had just come out of.

"JJ?" came Morgan's voice, before something was smashed violently into her temple. With a gasp, she slumped down onto her knees, her hands scrapping against the rough pavement as they came down to break her fall.

Wrong back door then.

Blinking blood out of her eyes and trying to stop the whirling in her head, she dizzily forced herself to her feet, staggering back a little from the effort it took. Her mind was still moving too slowly for her to really understand what was happening, but when she saw the baseball bat swinging towards her, she acted.

Using all the self-defense classes Morgan had taught her, along with her martial arts she had begun to learn with Emily, she ducked. She heard her attacker give off a surprised noise, probably not expecting his victim to be so fast, especially after bashing them in the forehead with a baseball bat.

Not giving the man time to recover, JJ launched herself blindly at the man that had attacked her. He gave a loud grunt as she slammed into him, and both of them tumbled to the ground. JJ heard the dull clunk of wood as the baseball bat fell away out of the man's grip.

Together, the two of them wrestled on the ground, JJ managing to pin and punch the man nearly three times full in the face before he got his wits back and slammed his fist into her stomach. Drawing back with a gasp, he pushed her off of him before lunging to where the baseball bat was.

JJ recovered herself enough to leap back onto the man, both of them scrabbling for the weapon that could mean the difference between living and dying for the FBI agent.

It was at this point that JJ realized that her earpiece had fallen out, since she couldn't hear anything her team was undoubtedly saying. She also realized that the fogginess in her mind couldn't have possibly just been from the blow to her head; no, somehow the unsub had managed to drug her, even with Reid and Prentiss's careful watching.

Blinking with this new awareness, she focused her eyes on her struggling attacker, fighting against the heaviness that was taking over her limbs. She recognized the man beneath her, and the pieces clicked together.

Their unsub was the bartender; with a flashy, handsome partner, they could distract a woman so he could slip something in her drink. And then when the woman had passed out, the bartender could easily remove her from his bar without suspicion; then later, he and his partner would go get her from where she had been stashed, so they could fulfill whatever sick fantasies plagued their minds.

Panic took over JJ as her arms suddenly went limp, and the man was able to flip her over, pinning her smaller form beneath his bulk. Less than a minute had passed since the fight had begun, but to JJ it felt like hours. Panting like an animal, the man grinned at her, the darkness and blood and wildness in his eyes making it look twisted and deranged.

"Got ya now, Sweetheart," he snarled, licking the blood from his lips. Everything was paralyzed in JJ, whether from the drugs or her own fear, she wasn't sure. All she could think of was her son waiting for his mommy back home, and Will, always so worried for her although he hid it as best as he could. She would never see them again, and if nothing else, that is what terrified her; she had worked at this job for too long to fear her own death. But her family, her team…

"Hey!" someone barked, and relief instantly washed through the blond woman. Morgan. Her team. They would never abandon her, they would always save each other.

"You have two seconds to get off of her, or I will shoot your ass!"

The unsub gave a bark of laughter, his eyes rolling madly down to meet JJ's. They looked almost completely black in the night, glinting sadistically down at his captive.

"Get off of her."

The quiet voice of Reid, boiling with concealed rage beneath the surface froze JJ's blood. Anyone that knew her friend would know he was meek, awkward around others, sometimes painfully shy and self-conscious. But if you broke past enough of his barriers and stung something at the center of him, he would release a cold and calculating fury, that quite frankly, scared her out of her mind. She had only seen him act like this a few other times in her life, and each time it had chilled her to the bone.

Something in Reid's voice froze the unsub as well, but when he turned and looked behind himself, he just coughed out another maniacal laugh. JJ could imagine what he saw; the skinny and laughably young Dr. Reid, pointing a gun at him with a shaky hand. Not exactly a very threatening image, compared to the pissed-off bulk that was Morgan, undoubtedly standing next to him.

"What, are you serious?" the unsub sneered, his eyes turning back down to JJ. The woman's eyes got wide when she saw a shadow suddenly loom over them, and the man followed her gaze above and behind him, his eyes also bugging out. Then he was tackled off of her.

JJ blinked tiredly up into the now empty space above her; the night sky was pretty, cloudy, so no stars, but still nice. Then Morgan's concerned face was hovering over her, and she smiled.

"Hey," she rasped out, and he gave her a strained smile in return.

Then she proceeded to pass out, not catching Morgan's reply and ignoring the sounds of blows being exchanged and the screaming of sirens around her.

XXXXX

JJ woke up to a sharp, sterile smell that she could taste on her tongue and which she instantly recognized. Many times, whether for herself or her team or even a survivor of one of their unsubs, she had visited a hospital, and she found that each one smelled the same. Cracking open her eyes, she observed, that like almost every other hospital, the room was also a blank, colourless white. This room she was in was darkened though, probably to let her sleep peacefully.

"JJ?" said a low voice, and JJ was startled to see someone was sitting in a chair by her bed. Emily, looking at her with concern and a fair amount of relief etched over her face.

"Hey," she said back softly, her voice sounding like nails on a chalkboard. Emily reached over and gave her a cup of water which she gratefully swallowed down in one gulp, soothing her burning throat.

"What happened?" she asked, giving the empty cup back to her friend.

"The bartender was the unsub," said Emily, and JJ nodded.

"Yeah, I figured that out when he bashed me over the head," replied JJ, memories trickling back to her. With her words, she realized she didn't have a pounding headache, odd after being hit with a baseball bat. "Did they give me something for my head?"

Emily nodded. "You had a very minor concussion, so they thought it would be safe to give you a bit of pain medication. Although I don't think Reid was too pleased. You know how he is whenever drugs are mentioned."

JJ gave a slow bob of the head, before another question sprung into her mind. "Reid, is he OK?"

Emily suddenly beamed brightly. "As Morgan tells it, when the guy pinning you refused to back down, Reid 'sprung like a freaking cat or something and tackled the guy to the ground before beating the everlasting shit out of him.'"

JJ blinked. "Reid?"

Emily nodded. "Reid."

"Hah," said JJ, thoroughly shocked.

"Hey, are you OK?" asked Emily suddenly.

"I'm fine, Em, why?" JJ said, slightly exasperated.

"When we were in the bar," JJ flinched, and Emily continued, "You seemed… uncomfortable." Leaving her words hanging there, Emily leaned back in her chair, letting her friend think over her words.

Finally, JJ said softly, "I know what I was doing, going undercover like that, was to catch a killer but… the entire time it felt like I was cheating on Will. Like I was betraying my son and husband, just for doing my job." JJ's blue eyes slid down in shame. "And I know it's not true, but I couldn't help feeling that."

Emily reached forward and wrapped her friend in a small half-hug. "I'm so sorry, JJ. You don't ever have to go undercover again. And don't feel ashamed, there is nothing wrong with being faithful to the ones you love."

JJ smiled thankfully. "Thanks, Em."

"Knock, knock," called a soft voice, and JJ looked up with a grin to where Reid was now standing in the doorway, a sheepish expression on his face. A white bandage was wrapped around his forehead and he was sporting a black eye, but otherwise he seemed fine.

"I'm gonna go get some coffee," Emily declared, standing up. As she passed Reid, she patted his arm. "And I'll get some for you too, genius."

He flashed a quick, relieved smile at her then carefully settled himself next to JJ. "You OK?"

"I'm fine, Spence, are you?"

Reid gingerly touched his head and winced. "I've been better, but I'll be fine."

"Thanks, by the way. Emily told me that you jumped the guy."

Reid blushed. "I didn't want to shoot him, but he wasn't backing down so I decided to surprise him. Nobody ever expects me to fight."

"That's 'cause it's not in you, Spence," she teased lightly. "Violence just doesn't flow through your veins."

Reid nodded thoughtfully. Then his face fell a little. "I'm sorry, Emily said we would watch your back, but we-"

"Spence, thanks," JJ said sincerely, cutting him off, and he ducked his head, rubbing his neck. He knew from her firm tone that she didn't blame him or anyone else on their team, and if she was willing to forgive him, he would drop the matter.

"No problem."

"And for the record," said JJ, forcing Reid to meet her eyes, "I know you guys will always have my back." Reid gave her a hesitant smile which she returned, patting his arm comfortingly like Emily had done.

Hotch suddenly gave a sharp rap at the door, interrupting the moment, and both of his agents looked up. "Prentiss said you were awake. Will and Henry are here to see you, JJ; do you want me to send them in?"

JJ sat up, wincing as the bruises all over her body ached. "Yeah, I'm good; send them in, please."

Hotch nodded but instead of instantly leaving, he said, "Nice to see you awake, JJ." Only then did he turn and leave.

"Well, I'll be going," said Reid, getting up slowly and stretching. JJ waved to him, muttering a good-bye absent-mindedly, already having caught sight of Will and her son coming into her room.

"Hey, honey," she cooed to her son, when Will lifted him up to sit by his injured parent. "How are you doing?"

Henry started babbling happily, eager to tell his mommy about his friends and school-work and anything else on his young mind, as Will grinned down at his wife, leaning forward and lightly pressing a kiss to her lips.

"You OK, JJ?" he murmured.

JJ smiled and relaxed against the back of her hospital bed, and for the first time since this case began, responded with absolute certainty.

"Yeah, I'm OK."
