So, I was heavily inspired by Dark-Supernatural-Angel's Supernatural Serum, and I was sad when I found out it was only four chapters. I really liked the dynamic between the Winchester brothers and Felicity Smoak, and it helps that I'm a huge fan of both fandoms. Well, anyways, I hope you guys enjoy!

It was an early night, and they were finishing up their rounds when Detective Lance called. There was a disturbance in the Glades, a typical theft, but the police officers at the scene weren't able to stop it. Detective Lance had not been there, only having talked with the two survivors of the shooting, but it had scared him unlike any other case. "We're on it," Oliver promised in his Arrow voice, and Detective Lance gave them the address.
They had just finished watching the video, visions of bullets ricocheting off their target, flying cars, blood everywhere, and pure-black sclera grinning at them flashing before their eyes, and they stood there in shock. "That could not have been Mirakuru," Digg said, looking to the three vigilantes who knew the drug the most.
"Last time I checked, Mirakuru did not give its user telekinetic powers," Roy said, still unable to process what he'd seen, and Oliver and Sara murmured their assents.
They began to list off possible theories, theories that they put down immediately after they were said, when Diggle noticed that their resident blonde genius had not said a word throughout all this. Oliver noticed as well. "Felicity?" he asked, grasping the blonde's shoulders.
The blonde sharply exhaled, clearly gathering her thoughts, before pulling away from her desk, surprising the others. "I- I think I know what this case is about," she said slowly, casting a worried glance at the monitor.
"You do?" Sara stepped closer to her friend, frowning. Felicity's tone worried her, as did the three other males.
"Yeah," said Felicity, nodding, "and it's not good." Trembling, she pulled out her cellphone and glanced at the four who were staring at her, confused and worried. "I- I need to make a call. I know people— two brothers— who know this type of stuff. They're experts in it, actually. Like, actual legends in their field, not that you know what that field is, exactly—"
Oliver cleared his throat, his eyes never leaving Felicity's. "Felicity," he stressed gently.
She cleared her throat. "Right. Sorry." She punched in digits in her phone, expelling the breath she was holding in her chest when she heard a familiar voice answer. "Hey, Dean, it's me, Felicity. What?" She paused before rolling her eyes. "Yeah, I'm fine, I told you last night… Yes. Dean, calm down, I'm not hurt." She squeezed her eyes, looking very much annoyed. "Look, I need your help." She groaned quietly and held the phone away from her ear, and the others could hear a muffled, male voice shouting.
"Dean, for fuck's sake, shut up for one second and let me explain!" Four sets of jaws dropped at the curse. "I'm fine, and I'm so sorry for snapping at you. It's just— I'm kinda panicking right now, and I know you and Sam trained me in this, but it's bad, like really bad. I mean, I thought Dick was bad, but I didn't expect— what? Dean, I said I'm fine! I'm not hurt!" Her eyes bulged momentarily, and she cast a glance at her listening friends. "No, they would never do that. I said I'm fine, now will you just shut up and calm down? I swear to all that is holy…" Felicity squeezed her eyes shut, her free hand coming up to rub her temples. "Where's Sam? He'll probably be more level-headed than you right now— ugh, Dean!" She stomped her foot in irritation. "I THINK THERE'S A DEMON IN STARLING CITY!" she bellowed, her chest heaving up and down as she glared at a spot on the wall.
"A demon?" Sara repeated, her voice coming out in a hiss.
Felicity must've heard her because she looked up at that, sending her a mouthed, 'Sorry,' before turning back to her cellphone. "Yes, a demon—" She growled, actually growled, and the other four gave each other wide-eyed looks because holy crap, that was actually kind of terrifying. "What do you mean, I should've told you? You wouldn't let me, you idiot!" She massaged her forehead, her eyes falling shut again. "Look, I kinda need you guys now. Like, right now. Think Cas can hook you up?"
Her eyes flew open then, wide and panicky. "Wait, I didn't mean it like that— stop laughing, Dean. Seriously. Stop." She rolled her eyes before an evil glint lit up her eyes. "You remember those books Chuck wrote? Because I seem to remember coming across this interesting piece of fiction in the internet with you and—" Her lips twitched. "Okay. Okay," She rolled her eyes. "Dean. Bye." She paused, her eyes softening, and Oliver felt a slight tightening in his chest. "Love you too. I'll see you guys later." She snapped the cell phone shut with a soft smile.
Turning back to her team, Felicity noticed the questioning looks in their eyes before sagging. "Who was that?" Digg asked, his eyebrows raised. From the corner of his eye, he could see Oliver's muscles subtly tensing and relaxing, tensing and relaxing, as if he didn't know what exactly he should be feeling at the moment.
Felicity rocked back and forth slightly on the balls of her feet. "One of the experts I told you about," she said lightly. She walked back to the desk, settling back on to her chair, before pulling out her tablet and hooking it to the monitors on the table. They watched as Felicity's fingers flew over the tablet, and on the monitor's screen, articles and pictures popped up, many of which took Team Arrow by surprise. "I never believed in the… paranormal, and frankly, I never probably would had it not been for these two." She pulled up a picture of two men, one with cropped, sandy hair, the other with long, flowing brown hair that barely grazed his shoulders.
"Hold up," Diggle said, his eyes narrowing as he recognized the two men. Then, they widened in shock as he remembered where he'd seen them. "Felicity!" he barked, unable to hide the displeasure in his tone. "Those men are serial killers." Turning to Oliver, Sara, and Roy, he elaborated, "They were on the FBI watch list for months—"
Felicity waved her hand. "I know, I know, but it really wasn't what it looked like, and I— we— that is, me, Sam, and Dean took care of that, okay? They're fine, you can trust them."
Oliver gritted his teeth as his eyes bore holes on her back. "And how do you know that?" he asked, his voice dipping into what sounded a lot like his Arrow voice.
Her eyes narrowed at the irritating man. "Because, Oliver, I've worked with them before," she said simply. "Back when I was in MIT." She sighed, rolling her chair back. "Long story short, they saved my life from monsters, I saved theirs, and they'd asked me for help while they helped train me. And even though they're often halfway across the States, they still call in to check on me often."
"Train you?" Oliver, Sara, Roy, and Diggle echoed, gawking at her.
Felicity nodded, choosing to ignore the surprise and inadvertent skepticism of her abilities. "It wasn't anything intense like you guys, but it was more than enough training for me. I can handle myself fairly well against the things that go bump in the night. Maybe not to the extent as Sam and Dean, but I'm still pretty good!"
Diggle chuckled, patting his blonde friend on the back. "I have no doubt about that, Felicity."
"Look, guys, Sam and Dean are good guys. They really are, and I have absolutely no reason to doubt them." She glanced up at them, her wide eyes pleading. "They saved my life. And I know that they would do that again tme and time again, no questions asked, just like you guys, so please… trust me."
Oliver exhaled, defeated. "Alright," he said reluctantly, much to the surprise of Felicity. "Do they know how to get here? Should we pick them up at the airport tomorrow?"
A smirk tugged at her lips. "I highly doubt that," she said, chuckling. "Dean does not like flying. Absolutely hates it, Nah, they'll be arriving a la Baby, a.k.a Dean's beloved car. Hell, I caught him talking to it from time to time. He's even worse than the Doctor."
"What?"
"Nothing," she said flippantly before turning back to her tablet, the other four finally dispersing. Disconnecting it from the monitor, the articles and crime scene pictures that were on the screen disappeared, and the interface returned back to normal. Nodding to herself, Felicity stood, grabbing her jacket on the way.
"Going home?" Digg asked, watching Felicity's movements.
"Nope," she said, popping the 'p' cheerfully and effectively gaining the attentions of the other three vigilantes.
"Felicity," Oliver bit out when she continued her merry way without a glance in his direction. "Where are you going?"
The blonde sighed, stopping on one of the stairs. "Okay, fine I'm sorry, do you guys want anything from Big Belly Burger? I was gonna get some for my guests—"
"Your guests?"
"I thought you said they were in the East Coast…?"
"Won't it be a while until they arrive?"
"I'd like a deluxe burger," Diggle chirped, earning an odd look from Oliver.
Felicity laughed. "Copy that, Digg," she said, sending her friend a wide grin. "And yes, I know I said that they live halfway across the country, but they travel a lot. They said they were nearby and that it won't take long. I think they'll be here in a couple hours, and yes, they're staying at my house, not some crappy motel in the Glades." She paused then before smiling tentatively. "Team dinner?" she asked, and it was the hopeful look in her eyes that had all of them agreeing.
After a relaxing evening out, Felicity, Oliver, Diggle, Roy, and Sara stepped out of the restaurant. "Thank god they're open 24/7," Felicity said happily. "And thank you guys for joining me."
"Even though that wasn't your plan in the first place," Sara teased, nudging the other blonde with her shoulders.
"Ugh, sorry, I was just excited," Felicity said, laughing. "I haven't seen Sam and Dean in a while."
"You're really close to them aren't you?" Sara asked gently, casting a quick glance at Oliver.
Felicity smiled and was about to answer when 'Eye of the Tiger' began to play almost obnoxiously. "Oh, excuse me, I think it's Dean. Hello?" She walked away from the group, but still close enough to hear her talk on the phone.
"You okay, man?" Digg asked, clasping his hand on Oliver's shoulder. He took in his pensive face and creased eyebrows. "What are you thinking about?"
"I'm having a hard time believing that demons exist," Oliver said slowly, his eyes still on Felicity.
"But Felicity was the one who told us," Diggle finished, smiling slightly. That girl was as honest as she was bright,
"You're in my house?" Felicity's exclamation drew all four eyes at her again. "How, it was only an hour since I— it's already 11?" She whirled around and gaped at her friends. "Guys, it's already 11! We've been in there for three hours!" She paused and glared at her phone. "No, I was not talking to you, idiot. Yes, I'm with my friends, and hell no, Dean. Uh-uh. I am so not doing that, I am not suicidal. And I am not discussing this with you again, Dean." Felicity groaned, throwing her hands up. "I'm hanging up!" she hollered into the phone. "I don't care! I'm hanging up, and unless you learn to shut up and actually listen, I'm not talking to you. Well, you can tell Sam that it's your fault— Oh, hi Sam. I gotta go, I think I've filled the quota of shouting into my phone today. Yeah, you can thank Dean for that. I know, I love him too. Okay, bye, I'll see you later."
Roy gave her an amused smile. "This Dean seems to like riling you up," he said, voice teasing. He bit back a grin when he heard a small growl from Oliver the Ice Queen.
Felicity scowled, her face flushing, but from anger or embarrassment or something else entirely, the team had no clue. "That's him," she said. "Annoying and never knows when to stop. Doesn't help his case that he's an idiot. I mean, he's not actually an idiot, the guy's actually kinda smart. Maybe not as smart as Sam, but still, he's not completely hopeless with technology—"
"Aww, 'Liss," a voice interrupted and sending the Arrow team members into high alert. They quickly gathered in front of Felicity, their stances on defensive. A man with cropped hair, an older version of the picture they had seen earlier at the lair, stepped out from the shadows, two others— one with long hair and the other wearing a trench coat. He smiled, lifting up his arms. "I didn't know you cared."
Oliver glared at him. "Who—"
The quiet "Dean?" from Felicity froze Oliver, and he turned to look at the blonde. "That's Dean?" he asked, pointing at the man as if he had expected more from him.
Dean didn't take the condescension so well. "Hey, buddy—"
Felicity pushed past the wall of bodies protecting her, and she marched up to Dean, stopping before him with her feet heavily planted on the ground and arms crossed. "Dean Winchester, I thought I told you to stay at my house, you asshat!" She pushed him angrily, and to her mounting irritation, he didn't budge.
Grinning, Dean gently grabbed her wrists, his eyes flicking briefly to Oliver's own narrowed blue, before glancing down at Felicity. "Hi, 'Liss."
"Oh, I am not falling for your damn smile again, Dean Winchester," she huffed, earning an even wider grin from the man. "And you— I am still mad at you, you reckless idiot!" She pulled herself from his grasp, took a deep breath, withdrew her arm, and punched Dean Winchester in the face. Sam burst out laughing. Felicity looked up, her eyes zeroing in on Castiel, and the angel actually stepped back. "And you— oh, ho, ho, ho, ho, I am going to enjoy ripping you a new one, Castiel. You think the Leviathans were bad? You obviously haven't met me."
Sam, still chuckling behind his hand, stepped up and decided to take pity on Castiel and Dean. "Felicity," he said, grinning and wrapping her into his arms, "it's nice to see you again, too."
Dean slowly stood up, rubbing his jaw gingerly. "It's almost been two years, Fel— shutting up." He held up his hands.
"I am not done with you guys," she said before turning back to Team Arrow. "We have more pressing matters here."
The brothers sobered immediately. "Right," Sam said. "The demon."
"It's the first one, too," Felicity muttered under her breath. "There's some vampires and ghosts here in the Glades, but never demons."
Dean frowned. "Whoa, what? Felicity Megan Smoak, are you telling me you've been hunting alone?"
Felicity shook her head. "Now's not the time, Dean."
"Seriously? Sam, you gonna let her get away with this?"
"For the moment, yes," Sam said, his attention now on the other four. "Hi there, I'm Sam Winchester."
John Diggle was frowning, Felicity noted, and that was not a good thing. "I'm aware," Digg said. "Your and your brother's faces were on TV for some time."
The brothers winced. "That… that wasn't us," Sam said, rubbing his neck.
"They're right," Felicity said. "Again, kinda a long story. We were dealing with a complete dick—" Dean snorted, and Felicity flushed. "Pun totally not intended," she hissed.
"Right," Sam said, glaring at his brother. "I know you don't trust us," he said, turning back to the others. "And, frankly, I wouldn't trust us as well."
"But," Felicity cut in, "they're the best of the best. Like I've told you guys." She gave her team a challenging glare.
Diggle backed off. "Alright, alright, I'll give you the benefit of the doubt."
"But," Oliver said, his voice ringing into the night and sounding dangerously like the Arrow's, "we're going to need to know everything. Like, for example, how you were able to arrive here when you were in Felicity's house just a few minutes ago."
Dean blinked innocently. "We drove?"
"Sure. But Felicity's house is twenty minutes away from here." Oliver crossed his arms and glared at the older man. "And that is not enough time for you to travel from her house to here."
"I can explain that," Castiel said. "But first, why don't we go back to Felicity's house?" Pushing the boys closer to Felicity and Team Arrow, he gathered them into a small and tight circle, and in the blink of an eye, they were in Felicity's living room.
"What the actual living fuck?" Roy exclaimed, his eyes round.
Castiel stepped back, his blue eyes serious. "That is Sam and Dean Winchester, and I am Castiel, an angel of the Lord."
