A/N: I think it's criminal how incredibly little content there is on Garcia & Charlie. Those two could literaly be the same person, they have so many similarities. I love the though of the two interacting, so I just had to write something about it.

There is a lot of hacking stuff in here, but there is no deeper knowledge of how it works needed. I don't know much about it either, apart from a basic google search.

Enjoy!


"Hey, bitches. I heard you managed to get yourselves into trouble again." Charlie let her backpack drop to the floor right there at the entrance of the bunker and pulled Dean into a hug.

"Hey, kiddo. Long time no see." Dean chuckled as he hugged her back just as hard. "Sorry for getting ourselves caught on camera and tipping off the police that we're maybe not quite so dead. Thanks for coming."

"Are you kidding? I can't leave my favorite pair of non-fictional superheroes hanging, can I?"

"Naturally," Dean replied with a grin that the redhead returned enthusiastically.

"Now, where do I set up?" Charlie asked as she picked her bag up again and pulled one strap over her shoulder.

"Sam's prepared the control room with everything he thought you might need," Dean said as he waved her down the stairs to the first floor of the bunker.

"Yeah, thanks, but no." Charlie said and unceremoniously dropped her bag onto the library table. "No offense, but I've seen this place's technology and believe me, you can tell it's from the last century." She turned her back to Dean as she started pulling multiple laptops and cables out of her bag and began to set up. "I brought my own stuff. All I need is the bunker's untraceable internet connection, a few energy drinks and some time."

Dean looked dumbfounded for a moment, but then he just shrugged. "If you say so. I'll get the other nerd; maybe he can help you a bit."

Charlie snorted out a laugh and energetically threw her hair out of her face as she sat down in her newly erected computer cave. "Nothing against Sam's computer skills, but I don't think he's quite ready for something like this. After all, you need me to hack into the fricking FBI."

Garcia spun one of her hair ties around her finger as she scrolled through some of her favorite community messenger board websites. She had more than twenty tabs open on her small private laptop that she held balanced on her lap as she sat leaned back in her comfortable office chair.

In front of her, multiple big screens were illuminated with various programs and files as well as the report that she was supposed to be working on. She was so bored with doing stupid reports. It was a slow week at the office. With no new cases, the team was using the time to catch up on their paperwork. It was sooo boring.

The last potential case had been a few days ago, when a call about an alleged sighting of the Winchesters had reached the BAU. Infamous serial killer brothers that were supposed to have died for no less than three times already. That was pretty much the only reason Hotch had even agreed to look over it. But with nothing more to go on than a greasy security footage picture, the team had decided that there was nothing they could do about the maybe-not-a-case case at the moment. Still, Garcia had quick access to all the files at the ready in her system if needed.

For now, her mind was elsewhere, however. She was bored with reports and had needed a distraction. She had learned her lesson about gaming at work, but no one could say anything against her scrolling message boards online. On her private laptop with its separate, mobile internet connection of course.

She distantly wondered, if she could maybe get away with slipping Reid some of her paperwork as Morgan was known to do, when she opened one of her favorite gamer chat boards. One new message blinked back at her.

QueenOfMoondoor56: Hi, haven't played in a hot minute. U up?

Garcia grinned at the invitation link her fellow gamer girl had sent. They'd played 'Blade & Soul' together a few times already and the games were always hella fun. With a deep sigh she glanced at the clock. Only 1pm. Damn.

TechGodessBG1: Sorry, at work

The Queen (as Garcia had secretly taken to calling her in her head) replied almost instantly.

QueenOfMoondoor56: Sucks. want some mood tunes?

TechGodessBG1: Definite

A link to an open Spotify playlist followed. It was titled 'Girl power for the win!' and Garcia grinned at the name as she clicked on it. The app opened in a new window and a loading signal appeared. Garcia frowned when it took a lot longer to load than usual. She prided herself in her fast internet connection. When the screen finally filled, a message appeared. 'Apologies, the site you are trying to reach has been closed.'

Garcia straightened in her chair and stopped playing with her hair tie as she leaned forward in concern. "That's weird," she mumbled.

She went back to the messenger board and typed:

TechGodessBG1: not working

It took a minute, in which Garcia anxiously tapped her leg, then an answer came through.

QueenOfMoondoor56: Sorry. Accidently closed the playlist. 'New link' working now?

Garcia hesitated for a moment, suddenly berating herself for so thoughtlessly clicking on a link. The whole situation seemed suspicious to her. With a few clicks she ran the new link through her background check system. It seemed legit. When she clicked it this time, the promised site opened.

"Nice," she whispered to herself. She opened the first song. 'I kissed a girl' by Katy Perry started playing and she had to laugh.

TechGodessBG1: working. ty. Dig it

QueenOfMoondoor56: no prob. I ll let u get back to work

Garcia groaned at the thought of working, but she had already wasted enough time. Besides, she now had great music to accompany her. So she closed her personal laptop and got back to working on her actual computers.

It was only about half an hour later that she was interrupted again. Morgan stood in her opened door. "Hey, Baby Girl. Wanna go get some lunch with me and the kid?"

"Oh you're a godsend, my Honeybun." Garcia let out a relieved sigh and pushed back from her table.

"Everything okay?" Morgan asked with a raised eyebrow.

Garcia shrugged, the movement betraying her frustration, as she pulled on her comfy over-jacket. "My computers are loading slower than usual. It's only like half a minute, but this is supposed to be state of the art technology. It's annoying as… well, you know."

Morgan grinned at her aborted curse. "You think there's something wrong with the servers?"

Garcia shrugged as she made sure to log out of all her open accounts and close all important programs and files. "Dunno. Something's buffering the system in the background. I'll take a look after lunch."

If she'd thought a bit deeper into it, she would have realized what was going on and not gone to lunch. She'd berate herself for that later; right now she was too hungry to notice.

They returned after a refreshing half hour long lunch. Reid was trailing after Garcia, excitedly telling her about the new 'Doctor Who' episode he'd watched last night. He followed the tech analyst into her office, claiming that he'd already finished all of his paperwork for the day.

Garcia smiled as she listened to his excited ramble. However, her smile dropped when she entered the room and her gaze fell upon her computer screens, where the cursor was moving on its own.

"What the…? No! No, no, no, no," she interrupted Reid as she rushed forward and practically threw herself into her chair and frantically started typing on her keyboard. She instantly noticed that multiple new files had been opened in the background of her system.

"Oh no, you don't," she hissed through her teeth as she frantically clicked and shifted through her programs. It took her a minute, but she finally managed to gain back the main control over the operating system. There were still traces of the other hacker, they weren't gone yet, but at least she was in charge again.

"Garcia, what's happening?" Reid leaned over her shoulder in concern, but she quickly shooed him back. She needed her space. "Someone hacked into my system," she said.

She saw Reid's eyes widen out of the corner of her eye. "Seriously. But how? Your programs are brilliant."

Garcia internally brightened at her genius boy's compliment, but she squished it down. She must have messed up somewhere if this other presence had managed to get in. "I don't know how, but I'm gonna find out," she promised darkly. "Now, let's see what you're so interested in…"

It took barely two minutes for her to find the files that had been accessed in the background.

Sam and Dean Winchester,

glared back at her from the screen.

"I see. So you're interested in immortal serial killers," she mumbled.

"Uhm, me?" Reid asked from beside her. Garcia jumped. She had all but forgotten about his presence.

"No, the hacker in my system. They're trying to delete the files, from the looks of it," she explained. Half her attention was still on the screens and keeping the other operator back from the files. Reid was leaning over her shoulder with his mouth half opened as his eyes tried to follow what she was doing.

"Boy genius, I love you and everything, but you are seriously distracting me right now," Garcia ground out as she lost another piece of code to the outside force.

"Sorry," Reid stepped back.

"Go do something useful. Ask if any of the others have copies of any of the stuff on the Winchesters on their computers. If so, tell them to print them out. Do not try to get into the server files; it'll distract me."

"I have physical copies," Reid said.

"I know honey, I'm the one that printed them out for your technophobic butt," Garcia said with a distracted pat to the young man's arm. "But those are just the most basic files. There are a lot more on here. Now, scatter my knight and fulfill your mission."

Her attention was back on the computer before he'd even exited the room.

It took her ten minutes, but she managed to push the other hacker back and lock them out of her system. "You're good," she murmured to herself. "But not as good as I. Be gone, be gone."

She smiled when one of her programs signaled that all outside activity had been removed. She quickly used another program that she'd written herself only a few weeks back to automatically reset and change all her passwords.

"And that, my dear friends," she said with a small bow to an imaginary audience, "is how it's done."

A second later a line of code flashed red and her grin faltered. "What the heck? How…?"

She quickly shifted a few windows around and saw the renewed activity in one of the background files. "Oh, you are good. Really good. Infiltrated my password program, didn't you?"

It had been a long time since Garcia had been up against a hacker this skilled and she couldn't help the thrill that went through her. She cracked her knuckles. "Let's do this."

And with that she went to town. Her fingers flew across her keyboard, muscle memory and the adrenaline of a good digital combat taking over.

This time it was a lot easier to push the other hacker back. They hadn't infiltrated the system quite as deeply, still hung up on some of the deeper passwords and security programs. Garcia managed to throw them out of the system in only four minutes and thirty seconds. This time she made sure to change all of her passwords manually and pull up some more serious digital security walls. She checked over her key-programs again to make sure the hacker was removed completely.

When she was satisfied, she leaned back in her chair and let out a deep breath. She allowed her heat-rate to calm down again. She had to admit, the challenge had been fun.

She took a deep gulp from her tea, that had gotten cold by now, before turning back to her loved computers. "Now, how did you get into my system," she murmured as she thoughtfully tapped one of her fidget toys against her desk.

Her mind went back to earlier that day. The link that had already seemed fishy to her at the time. She straightened again in her chair. "Oh, Queen of Moondoor. Did you dare?! Did you dare break into my digital babies?"

She took out her personal laptop and turned it on. The first thing she did was to do a sweep of the software for any viruses or malware. When that came up blank, she opened the website from the messenger board again.

TechGodessBG1: did you seriously just hack me?

QueenOfMoondoor56: I can neither confirm nor deny that ;)

Despite the seriousness of the situation, Garcia couldn't suppress her grin at the cheeky answer. So apparently the Queen was a hacker. A quite talented one at that.

TechGodessBG1: Gotta say. That was impressive. Could probably still teach you a thing or two though

QueenOfMoondoor56: We ll see about that ;) 3 3

Garcia frowned at the message. She quickly returned her gaze to her FBI computers. She used a program of her own making to scan for any attempted security breaches. At first nothing jumped out at her and she was almost ready to brush the comment off as a joke, when something caught her eye.

She pushed a few programs aside and opened the general server port overview. A disbelieving laugh escaped her when she saw the Queen trying to get in through one of the ports. "An open port? Is she serious? This is the fricking FBI, girl. It won't be that simple. Try again."

It took the tech genius barely five seconds to close and secure all the ports. Most of them had default security anyway. Then she tried to trace the invading signal back to its source. She was surprised when there wasn't even the beginning of a digital trace from the Queen's side.

Suddenly, the coding language on the screen, where she was following the Queen's path in the servers, changed. Garcia frowned, thrown for a loop for a moment. Then the smile returned. "Switching the coding language," she exclaimed, jumping back into action and changing her own coding as well. "C, nice. Good move."

"Garcia!" her eyes widened at the sudden voice behind her and she spun around. Hotch stood in the door to her room, a serious look on his face. Garcia gulped. Shit. "Reid told me you got hacked."

Her face burned with embarrassment and she ducked in her seat in shame. "Yes, sir. I'm so sorry, sir. I'm working on it, sir," she squeaked in a high pitch.

"What exactly happened?" her boss asked as he stepped up behind her and looked over the lines of coding on the screens, clearly not understanding any of it.

"It wasn't my fault, sir. Well, technically it is, but I swear it's not like last time. I wasn't even connected to the office internet. I don't know how this could have happened-"

"Garcia," Hotch interrupted her calmly. The woman nervously tapped her fingers against the table. She still had to keep at least some of her attention on the still ongoing battle of coding on her screens, adding to her overall stress. "I trust that you weren't careless. I just need to know how they got into your system and if it's something the other departments or the IT needs to be briefed on."

Garcia bit her lip and avoided eye contact in embarrassment. "It was a phishing link, sir. It's stupidly basic, I know. I should have been more careful-"

"Garcia," Hotch set a careful hand on her shoulder. "It's okay," Hotch continued. "It happens. All I need to know is, if you can fix it."

She took a deep breath, trying to regain her composure in front of her boss. She pushed a hand through her slightly wild hair and nodded to herself in determination. "Yes, sir. Definitely."

"Okay, then don't worry. I believe in you." Another encouraging squeeze of her shoulder later he left her alone and Garcia returned all of her attention to her computer. "Alright. Let's do this."

With her full attention back on task, she had no problem securing all the port entrances that the Queen kept attacking over and over again. "Seriously, what's she trying to accomplish? This is the fricking FBI, does she really think she can hack in here through something as simple as an open port?" Garcia kept talking to herself as she easily pushed every new attempt by the Queen down.

After a few minutes the onslaught of attempted attacks subsided and Garcia leaned back in her chair with a satisfied grin. Nothing happened for a few more minutes, before a light knock on the door had her looking up. Reid was standing there with a coffee in hand. "Hey. I thought you might need some caffeine," he said as he put the cup on her table.

"Thanks, boy genius. You're my hero." Garcia took the cup to her lips and took a few long gulps as she kept carefully monitoring her programs for any sign of intrusion.

"So, what's happening there?" Reid asked with a hand motion towards the computers.

Garcia regarded him for a moment with a raised eyebrow. Reid wasn't typically the type to ask too many questions on how technology worked as long as it got him the required results. But then again, he was a curious person and always eager to learn new things, so she shrugged and started to explain in as few technical terms as she could.

"This hacker - she calls herself Queen of Moondoor - she sent me a phishing link and got into the FBI database system. She must have brute forced herself through some of my passwords, cause she managed to get deep enough to get to the files." She gestured to the files of the Winchesters that were displayed on the far right screen. "She must have infiltrated my password program while she was in, cause when I changed them, she could read the new ones and get right back in. But I upped the security and put some of my programs a-la-Garcia in place, so she shouldn't be able to do that again. Then she-"

Garcia cut herself off when she noticed a movement in one of the operating programs. "Hey! Oh no, you don't!" She quickly scooted back to her keyboard to retaliate, but found to her shock that she couldn't control the cursor of her mouse. The Queen had taken control of her entire operating system.

"Shit, shit, shit," she muttered as she frantically tried to stop the Queen. When she found that she couldn't control anything in any of her computers, she quickly scooted to the side and fired up a previously off-turned screen at the next table.

"What's happening?" Reid asked nervously. He eyed her in concern, not used to hearing her swear like that.

"Boy genius, I need you to lock in with your account. Quick!"

Reid did as he was told, while Garcia was nervously clicking her nails together. He was being painfully slow about it, in her opinion, and right now every second mattered.

As soon as the screen was unlocked, she pushed the young man aside and started opening various programs. She needed to find an access point into her compromised account and then write a program that would allow her to regain control.

She hacked into her own system easily, knowing all the security walls and protections she'd put in place by heart. Simultaneously, she started writing the needed program, using the time whenever the first window was loading. The program was almost finished, when there was sudden pushback against her advances into the system.

"Oh, you wanna play it like that? It's on!"

With a few lines of code, she went around the new block. They battled back and forth for a while. The lines of code were streaming out of her and she felt herself slip into her favorite mindset. The hacker zone. She got further this time, was almost in, when the Queen suddenly changed her strategy, pushing her back again.

Garcia couldn't help the grin that was starting to form on her face. "Oh, smart girl! Good move. Now let's see how you like this." She quickly rerouted her own advances.

"You are enjoying this," Reid suddenly spoke up from beside her.

Garcia shot him an incredulous look. "No! I don't know how you could have gotten that idea." When their eyes met, however, she couldn't help but grin again and when he returned it, she winked at him. "You didn't see anything."

She went back to coding. Her algorithm was almost finished. Now all that was left was to get into the core of the system. If she could just reroute all network activity to the FBI's immediate hard servers, then the Queen would automatically be out of business.

Reid continued to hover over her shoulder as she leaned forward in her chair. His presence was starting to irritate her as her stress level rose with every minute that she was blocked out.

"Can you explain to me what's going on," Reid asked. "Why did you need my lock-in?"

Garcia hummed, distracted, "She must have created a backdoor on the SSH server and managed to get herself super-user privileges to all my accounts."

Reid squinted at her in confusion. "What does that mean?"

"She's in control of everything in my account."

"But-"

Garcia cut him off with another curse when she saw the first file being deleted on her other screen. "Reid! I need to concentrate. Go sit and don't distract me!"

She would have felt bad for snapping at him, but she was distracted. The time for games was over. Files were being deleted. She was running out of time to get control back, before the damage would be too much.

She had just seen another file disappear from the database, when she finally managed to get around the Queen's final security wall. She was in.

Garcia quickly fired up her by now finished program and used it to take control back. Barely three seconds later the account was back in her hand and just as quickly the Queen was out.

Garcia let out a relieved sigh and slumped back in her chair. The adrenaline was still buzzing in her veins and she was still riding the high of a high-stake hacking job. However, when she went over the internal database and deep net backups, her happy demeanor was starting to fade. The Queen had managed to delete quite a few files. A sense of failure and guilt was starting to pool in her stomach. She should have been faster.

Behind her Reid nervously cleared his throat. "Uhm, are you done? Did you do it?"

"Yeah," she sighed, resigning herself to having to come clean about her partial failure. "But a few files still got deleted."

"Can't you get them back?" Reid asked and Garcia had to suppress the urge to give him a pitying look. Poor child, so smart and yet so clueless.

"Those were the backups, honey. I'm afraid they're gone for good." She looked further through her various programs. At least there were still traces that told her where there used to be files. "Looks like she managed to get the main files and a few background stuff; most of Agent Hendrickson's former profile is gone." She sighed again and grabbed one of her fidget toys in an attempt to calm herself and distract her nerves from the on-setting post-adrenaline anxiety. "Hotch's gonna kill me," she murmured.

"Hey," Reid waited until Garcia raised her head and looked in his direction. Though he wasn't touching her, he had a hand half-raised as if he'd thought about it and on his face was a sympathetic expression. "It's gonna be fine. We can build a new profile and we still have my physical copies. I read all the files that appeared on screen while you were doing your thing. I'll transcript them for you."

Garcia felt her eyes fill with tears at the gratefulness that flooded her at his words. Without thinking, she jumped up and rushed to pull him into a tight hug. "Thank you so much!"

At first he stiffened at the initial touch and she was just about to pull back and apologize, when he relaxed in her arms and returned the hug. "Of course. It's all gonna be okay."

She released him after thirty seconds, aware that he wouldn't be comfortable with any more prolonged contact and gave him a watery smile. "You're a lifesaver."

Reid chuckled awkwardly and looked away. "We should probably tell Hotch what happened."

Garcia grimaced. She'd rather not. But she knew it was necessary. They'd need to evaluate whether the hacking attack had been random – a tech genius kid hacking into the FBI as a challenge – or if it had something to do with the Winchesters' supposed reappearance. She really hoped it wasn't the latter. Now that she thought about it, the timing was almost too convenient and to their knowledge, none of the Winchesters had any kind of advanced hacking background. Maybe it was all a set-up. Orchestrated to seem like they were back to keep the BAU busy from other cases. If that was the case, then maybe the first video had been a fake as well. She'd have to reanalyze it. And she still had to try and trace back the attack to a location or person.

Garcia sighed at the thought of all the work that would be awaiting her. But secretly she couldn't help the spark of excitement. It had been a long time since she'd had as much fun hacking as today. The Queen was seriously good. When the formal investigation was over, she wouldn't mind digging her brain and texting a bit more.


A/N: I hope you enjoyed the story. Please consider leaving a review if you did.

There might not be a huge audience out there for this specific character crossover, but I like the concept of them interacting a lot. I'm considering writing more chapters. Let me know what you think about that and if anyone would be interested in reading more about those two girls.
