Rowena dropped a few more ingredients into the bowl, double-checking the measurements before resting her hands on the table. She glanced up at the four sets of eyes staring holes into her face and rolled her eyes, standing straight again.
“Alright, boys,” -Rowena took a step back, gesturing to the bowl- “everything’s ready.”
“You sure this’ll work?” Dean grumbled, eyeing the bowl suspiciously.
“It should,” Rowena huffed, shrugging one shoulder. “I can’t be sure how angel grace will affect it, though.”
Cas looked over at Jack, his brows pulling together while Jack’s eyes flickered around the bowl, admiring the different ingredients. “Let’s do it,” Cas grumbled, absently scratching at his forehead.
“Hands on the bowl, boys,” Rowena ordered, curling perfectly manicured fingers around the rim. They stood around the bowl, hands almost touching, waiting for Sam to strike the match and get his hand back on the bowl. Rowena mumbled something Dean couldn’t quite make out, and then the bowl lit up with a bright blue flame; Rowena’s hand tightened on the rim, but before she could yell for them to get back, the flame sputtered and sparked.
“Oh, shit,” was all Dean got out before they were sucked off their feet, leaving the library empty.
The FBI field office was bustling outside the conference door where the Avengers were sitting around a table. After the fiasco with Hydra and SHIELD, the team needed somewhere to sit down with Fury that wasn’t two hours outside the city. Fury pulled some strings and managed to get the FBI to buckle and let them use a conference room once a month.
Fury stood at the end of the table, yapping and pointing at a projection, barely keeping the attention of 90% of the team. Tony was doodling on a piece of paper, keeping his hands busy as he absorbed Fury’s information. Steve was locked in on Fury like the good agent he was while Bucky shifted his chair side to side next to him. Nat and Clint were mumbling back and forth, glancing at Fury even though there was a good chance they weren’t really listening. Thor sat opposite Fury, mindlessly rubbing his stubbled cheek as he nodded along; Bruce was hunched over beside him, taking sloppy notes. Vision even seemed board while Wanda spun a pencil around the table, periodically poking Peter to keep him awake.
A high-pitched ringing jolted the entire room to attention, stopping Fury midsentence; he grumbled, fishing the phone out of his pocket. “What?”
“That never happens,” Tony chuckled, leaning back in his chair, earning a glare from Fury.
“Well, good thing I have the Avengers in the city,” Fury grumbled, aggressively ending the call. “Look at that; your trip wasn’t for nothing.”
“What’s going on?” Steve cut in, furrowing his brow.
“We picked up a power surge a few blocks from here,” Fury provided, waving away the hologram, gesturing for everyone to stand.
“Okay, what’s that have to do with us?” Clint asked, stumbling over Bucky when Nat pushed him forward.
“It was four times what the average power surge should be,” Fury snapped, hurrying the team through the door.
“Yeah, that doesn’t sound good,” Bucky sighed, running a hand through his hair.
“Suit up; you’re leaving in ten,” is what Fury left them with before disappearing down the hall. The group let out a collective sigh before hurrying towards the hanger to get changed.
Dean landed first, groaning when he felt the rough grit of concrete under his cheek. He tried to push himself to his hands and knees only for 200-and-some pounds of pain in the ass brother landed on top of him. Cas, Jack, and Rowena followed, creating a groaned pile of bodies as they tried to get their bearings again.
“Get…off!” Dean gasped, trying to roll out from under the pile.
“Oye, stop moving!” Rowena shouted, hanging onto Jack to keep from tumbling to the ground. The rest of the pile stopped squirming, letting Rowena land on her feet before helping Jack up; Cas followed, hefting Sam to his feet to take the weight off Dean. Dean rolled onto his back, staring at the gray sky as he pulled air into his lungs.
“Fuck,” he panted, slamming his eyes shut.
Peter and Clint perched on a roof, scanning the streets while also keeping an eye on the Avengers scattered around the area. Thor and Bruce leaned against a random brownstones railing in an attempt to blend in while Bucky and Wanda leaned against a bench across the street from them. Steve and Nat walked along the block, subtly clearing the civilians, and Vision and Tony waited a few blocks away for the green light before flying in.
“All clear,” Steve mumbled into his earpiece.
“Let’s move in,” Nat added. The scattered Avengers jumped into action, following the GPS coordinates down the now-empty street; Peter brought Clint down from the roof as Tony and Vision flew in the join them. Tony fell in step with Steve at the front of the group, his suit disappearing as he walked while Vision followed behind Wanda; as they got closer to the coordinates, muffled shouting from a break in the buildings caught their attention. The Avengers approached the edge of the wall, half of the group hurrying across the gap to press themselves against the other building.
Tony leaned around the wall, narrowing his eyes at the five figures scattered around the small alleyway. A ridiculously tall man clad in orange flannel rubbed a hand over his face, his long hair falling from where it was tucked behind his ears. A few paces away, another dark-haired man wearing a suit and trench coat was whispering to a kid that couldn’t be much older than Peter. The last two, a shorter man in blue flannel, was looming over a short red-haired woman, visibly seething as his jaw ticked.
“You said this would work,” the shorter man growled, stepping a hair closer to the woman, who didn’t even flinch.
“No, what I told you was-“ the redhead was cut off when the short man threw his arms up and turned his back to her, letting out a bitter laugh.
“Oh no! Don’t you dare.”
“Look, guys, now really isn’t the time,” the taller man cut in, rubbing at his eyes with his thumb and pointer finger.
“This is what caused the power surge?” Bucky mumbled, raising an unimpressed brow.
“Not what I would’ve pictured but whatever,” Tony sighed, stepping away from the wall. The rest of the Avengers followed suit, stepping up behind Tony in a loose formation to follow him towards the group. The dark-haired man noticed them first, immediately pushing the kid behind him; this movement drew the attention of the three arguing, and they fell quiet, turning to face the approaching Avengers.
“Great,” the shorter man huffed, rolling his eyes.
“Hands where we can see them,” Steve started, moving to Tony’s side. “We don’t want any trouble.”
“Manete,” the redhead yelled, flinging a hand out. Tony tried to take a step closer only to find his feet stuck to the ground; he looked around only to see the rest of the team looking down at their feet, too.
“Damnit, Rowena!” the shorter man yelled, turning a death glare at the woman, Rowena.
“Hands up, or I’m shooting,” Bucky yelled, aiming his handgun at the woman. Instead of looking scared, Rowena giggled, her eyes squinting as she covered her mouth.
“Oh, darling, that won’t hurt me.” Her Scottish accent was a little hard to understand, but Bucky still got the general idea and scoffed, shaking his head.
“You don’t know that, Rowena,” the dark-haired man cut in, squinting at her.
“Castiel,” she purred, resting a hand on Castiel’s arm, shooting him a wicked grin. “It hurts that you doubt me. Do you see them moving?” Instead of answering, Castiel glared at her, shrugging her hand off, making her smile wider.
“Cas, can I learn that spell?” the kid asked, tugging on the man’s trench coat sleeve.
“Jack now’s really not the time,” the taller man sighed.
“Enough!” Steve yelled, his jaw clenching and unclenching. “I want hands in the air, and I want names.” The five opposite the Avengers shared a few glances before raising their hands, a few exasperated sighs falling from the group. “Names, now,” Steve ordered.
“Dean Winchester,” the short man grumbled, still glaring at the redhead.
“Rowena MacLeod.” Rowena’s smile sent shivers down a few of the Avengers’ spines, but they stayed quiet.
“I’m Sam Winchester,” the taller man sighed, turning to look at the last two.
“Castiel” -Castiel rested a hand on the kid’s shoulder, giving him a tight smile- “and this is Jack.”
“Hello,” Jack greeted excitedly, raising one hand.
“Now…” Dean trailed off, finally taking a good look at the people blocking their exit. “No fucking way.” Dean’s eyes darted around the group, his face lighting up with excitement as he blindly smacked his brother.
“What, Dean,” Sam hissed, grabbing his brother’s wrist.
“Dude…dude…oh shit,” Dean gasped, looking like he was ready to start bouncing in place. “Do you know who these people are!”
“Obviously not,” Sam sighed, rolling his eyes.
“They’re the fucking Avengers, man!” A nervous yet ecstatic smile spread across his face as he shuffled around Rowena, getting closer to Castiel and Jack.
That stopped Steve short, and he glanced around at his teammates, noticing the universal confused looks on their faces. “Uh, yeah, we are,” Steve confirmed, blinking a few times. The team had run-ins with excited fans before, but something was different about this; Dean almost seemed in disbelief.
“From the movies?” Jack gasped, turning owlish eyes on the superheroes.
“That can’t be right,” Castiel mumbled, squinting at Dean. The longer they listened to the strangers, the more confused Tony got before he finally had enough.
“Look, release our feet,” Tony started, turning his gaze on the redhead.
“Rowena,” Sam huffed, side-eyeing the woman until she caved, waving a hand but not without rolling her eyes.
“Bucky and Wanda, stay with us,” Tony started, scanning his teammate’s faces. “Everyone else, head back to Federal Plaza; we’ll meet you there.” Bucky and Wanda shuffled forward, standing in line with Steve and Tony while the rest of them reluctantly moved towards the street again. Tony only turned back to their interesting visitors when they were alone again.
“You need to come with us,” Steve spoke up, drawing attention back to him.
“Actually, I think we need to go home,” Castiel countered, leveling Steve with a glare that made fear buzz under their skin.
“How?” Sam asked, leaning forward to see his friend’s face.
“What about the God squad?” Dean shrugged, glancing between his brother and his best friend, ignoring Rowena’s laughter. “I’m surprised they haven’t come to smite us out of existence.”
“They know we’re here; I can hear them,” Castiel grumbled, squinting at the ground. The remaining Avengers just stared in confusion as they tried to figure out what the hell was going on.
“God squad?” Bucky scoffed, shaking his head. “What kind of nutcases are you people?”
“No, no, no,” Dean rushed out, clapping a hand over Castiel’s mouth when he tried to talk again. “You either,” Dean snapped, pointing at Jack.
“Oh,” Jack hummed, furrowing his brow before nodding. “They don’t know angels exist.” Dean threw his hands up, releasing Castiel, and turning away, resting one hand on his hip while he massaged his temples with the other.
“You really thought that would work,” Rowena giggled.
“Can it, Red,” Dean snapped. Tony, Steve, Bucky, and Wanda looked at each other before bursting into laughter that echoed off the building around them, using each other to stay on their feet.
“Angels,” Wanda managed between giggles.
“Enough!” The four froze, their laughter cutting off abruptly at the booming voice, and they straightened, gaping at Castiel, who the voice belonged to. Bright blue light burned in his eyes, making his already intimidating scowl that much scarier, and the Avengers seemed to be the only ones fazed by it.
“Alright, Cas, dial it back with the angelic wrath,” Dean chuckled, resting a hand on his friend’s shoulder.
“Holy shit,” Bucky breathed, breaking the silence first.
“As you can see” -Rowena took a step closer, gesturing to Castiel behind her- “he’s an angel with a short temper that would like to go home. So, if that’s all, we’ll be on our way.”
“What no wings,” Tony scoffed, still not believing angels were real.
“I have wings,” Jack cut in, his face lighting up with a smile.
“Okay, I’ve had enough of this,” Steve snapped, narrowing his eyes. “You’re getting in the van waiting on the street, end of discussion.” Dean, Sam, Rowena, and Castiel shared a look, seemingly talking with their eyes before they all deflated.
“Lead the way,” Sam mumbled, giving Steve a tight smile. Bucky and Wanda moved first, periodically glancing over their shoulders, watching the five strangers begrudgingly follow as Steve and Tony brought up the rear.
Bucky noted how they all moved and interacted; Jack walked between Dean and Castiel, leaning in when Dean wrapped an arm around his shoulders to whisper something to him. Castiel let a slight smile tug at his lips as he watched them and Bucky the feeling he was looking at two fathers with their son. Sam and Rowena walked a few paces behind them silently, stealing glances when the other wasn’t looking, and Bucky could almost see the tension between them.
The gray van sat idling near the curb, the side door sitting open; Castiel tilted his head, looking at Dean for an answer to a question he hadn’t voiced. Bucky and Wanda settled in the fourth row behind where Steve, Sam, and Rowena sat in the third row, giving Dean, Castiel, and Jack the row directly behind the driver and Tony.
“So let’s try this again,” Tony grumbled, turning in his seat to face the van full of faces. “Why were you five at the center of an enormous power surge?”
“That’s my fault, dear,” Rowena spoke up, bracing her hands on the seat between Jack and Dean. “I told Dean I didn’t know how the spell would react to angel grace, but he didn’t listen.” Rowena playfully looked at the ceiling, shrugging and shooting Dean a sweet smile when he turned to glare at her.
“Spell? Angel grace? What the hell are you talking about?” Steve cut in, looking down at the redhead next to him.
“Uh, y-yeah,” Dean started, suddenly fidgeting like he was nervous. He turned in his seat, only meeting Steve’s eyes for a split second before glancing away, attempting to hide his excitement.
“Jesus Christ,” Sam groaned, throwing his head back. “Should I just call you Captain?” Steve leaned forward some, using a hand to steady himself in case they hit a bump, and studied Sam for a few seconds before nodding. “Well, Captain, I think what happened is the spell we were attempting to use brought us here from our universe because of Cas and Jack’s grace.”
“What’s grace?” Wanda questioned from behind Sam.
“Our life force,” Castiel provided, turning just enough for the other to see his profile. “Angels have grace instead of souls like humans do.”
“Where were you trying to go?” Tony wondered aloud, shrugging when Steve shot him a dirty look.
“Hell,” Jack chirped, earning a groan from Dean and Castiel.
“It looks like I’ll need to make some adjustments to that spell before you boys can come to visit,” Rowena commented, picking at her nails.
“Back up, Hell?” Tony choked out, his eyes bugging out.
“Well, of course, dear,” Rowena chuckled, crossing her legs and nearly stabbing Steve with her heel. “I hope things will be alright until I return.”
“Why the fuck would you want to go to Hell?” Bucky asked, staring at the back of her head, his eyes narrowing in disbelief.
“I’m queen,” Rowena replied with a smirk.
“What kind of fucked up world are you people from?” Tony’s eyes darted around the van, watching each of their guests’ expressions change, ranging from defeated to irritated.
“One you don’t want to visit,” Sam snorted, crossing his arms.
As soon as they reached Federal Plaza, FBI agents descended on the van, dragging the five strangers from their seats and slapping cuff on them immediately.
“Cas. Dean,” Jack whimpered, looking like a child as he searched for his fathers.
“Jack,” Dean shouted from where he was being pinned to the ground. “Don’t do anything, okay? You do whatever they tell you.”
“But…” Jack started, looking down at the handcuffs around his wrists.
“No!” Castiel yelled, lunging towards his son only to be wrestled back. “Jack, please.” The boy nodded faintly, letting his hands hang in front of him; Sam wasn’t putting up a fight until Rowena cried out and attempted to stomp on the foot on the agent cuffing her. Sam surged toward, shouting at the agent for manhandling Rowena before he was yanked off his feet.
“Does something feel wrong about this?” Wanda whispered to Bucky, turning wide eyes on the ex-assassin.
“I know what you mean,” Bucky replied, his brows pulling together.
“They’re a threat,” Steve sighed, crossing his arms and ignoring Bucky and Wanda’s pained gazes.
Jack sat cross-legged on the small cot in his cell, looking around with child-like wonder. Cas’ cell was next to his, where he sat hunched over, his head in his hands as he listened to Dean shouting and banging on the transparent wall opposite him. Sam was sprawled on his bed, one hand behind his head, the other swinging off the side of his bed, occasionally shouting at Dean to shut up. Rowena paced her cell, mumbling under her breath and attempting a few spells despite the missing ingredients.
“You done?” Fury snorted, approaching Dean’s cell. Dean immediately stopped, his eyes growing wider as he took in the face in front of him.
“You’re Nick Fury,” Dean laughed, stumbling back a step.
“So I’ve heard,” Fury huffed, crossing his arms. “How do you know about the Avengers?”
“Uh, the movies?” Dean stuttered, glancing over his shoulder at Cas, who was looking at him now.
“What movies?” Fury snapped, narrowing his good eye.
“Look in our world you guys aren’t real. You’re characters in comic books and movies,” Dean mumbled, rubbing the back of his neck.
“Ah yes, this other world you’re from where angels exist,” Fury scoffed, shaking his head.
“Angels exist here too, right Cas?”
“Yes,” Cas answered, propelling himself to his feet and strolling towards the front of his cell. Fury turned away from Dean, stopping a few inches from Cas’ cell, scanning the face of the supposed angel.
“Then why haven’t I ever met one, Cas.” Cas narrowed his eyes, not liking the condescending way the man with one eye used his nickname.
“There’s no reason,” Cas replied, his tone clipped. “They have no business on Earth in this universe.”
“How convenient,” Fury hummed, raising a brow at Cas.
“Look, we just wanna go home,” Sam cut in, now leaning against the front of his cell.
“Oh, that’s all,” Fury laughed, stepping away from Cas’ searing glare. Dean watched Fury wander towards his brother before glancing at Cas, his eyes widening in fear; the angel was running a hand over the transparent surface when he suddenly pulled his arm back like he was going to throw a punch.
“No!” Dean yelled, plastering himself against the plexiglass or whatever the stupid cell was made of. Cas froze, his eyes flickering up to meet Dean’s, but he didn’t lower his fist. “Cas, don’t.”
“I’d listen to your friend. We learned our lesson after the Winter Soldier punched his way out of a supposedly impenetrable box,” Fury explained.
“You better know what you’re getting us into, Cas,” Dean grumbled, walking to the back of his cell. Fury’s eyebrows pulled together as Sam took a deep breath and followed his brother’s lead, lazily wandering towards his cot again.
Cas took a deep breath and went for it; Fury jumped when a fist exploded through the barrier, and he stumbled away, covering his head when Cas used his grace to blow the spiderwebbed material into the hall. Cas stepped out, squinting down at the shattered remains of his cell before lifting a hand, repeating the action with his grace, and blowing the front of Dean’s cell open.
“Awesome,” Dean laughed, stepping out to meet Cas.
An explosion rattled the building sending puffs of plaster dusk raining down on the conference room where Thor, Steve, Bucky, Tony, Wanda, and Nat were lounging.
“What was that?” Thor asked, getting to his feet instantly.
“Great question, pointbreak,” Tony mumbled, jogging to the door, poking his head out.
“Are Bruce, Peter, Clint, and Vision still in the building?” Steve asked, grabbing his shield from where it was leaning against the wall.
“No, they went to pick up something to eat,” Nat sighed, following Tony into the hallway. The building shook again when another explosion went off, sending the six Avengers stumbling into the walls; they got their footing again when an FBI agent ran around the corner, skidding to a stop in front of the team.
“Thank god,” the agent sighed, bending in half to catch their breath. “It’s the prisoners.”
“I told you!” Steve yelled, scowling at Tony.
“Yeah, whatever, you can give me shit later, Capsicle,” Tony grumbled, taking off for the steps at the end of the hallway. Thundering footsteps echoed through the stairwell as they ran for the basement; Steve made it to the bottom first, sending the door flying off the hinges with one kick. The team flooded the hallway just as the last cell exploded under Castiel’s fist; he offered a hand to Rowena, helping her step out to join the other near the end of the hall.
“Woah,” Bucky breathed at Steve’s side. “I couldn’t even break that shit with one punch.”
“Stop!” Steve yelled. The five at the end of the hall turned on their heels, anticipating a fight; Dean smiled, looking a little too excited before Cas barked something they couldn’t hear, and his smile fell away.
They moved at the same time. Steve’s shield went flying through the air just as Dean started for them, but he rolled out of the way, and the shield broke through the plaster. Dean and Bucky met in the middle of the hall, exchanging blows; Castiel stepped up, facing Steve as Sam ran for his brother. Thor cut off Sam’s advance, rocking him back with a well-timed punch, dropping Mjolnir; Steve surged forward only for an invisible force to stop him, and no matter hard he fought, he didn’t budge.
“I don’t want to harm you, Captain,” Castiel warned, flicking his wrist, sending Steve flying across the room, taking Tony out in the process. Wanda and Nat jumped out of the way, rolling to a stop; Bucky stumbled over Nat in the narrow hallway sending him to the floor. Nat jumped to her feet, spinning to kick at Dean, her boot snapping his head to the side. Wanda walked up to Castiel, magic swirling around her hands; he managed to block the first few blows, but he slipped, and a ball of scarlet magic slammed into his chest, sending him flying back.
“Almost ready!” Rowena yelled, drawing everyone’s attention to the end of the hall. Sam had ducked under Thor’s fist, backing down the hall away from his family, but when he heard Rowena, Sam lunged around Thor again, giving him an opening to run when he needed to. Dean yelled for Cas, distracting Sam long enough that Thor landed a brain-rattling punch, sending Sam sliding down the hall, coming to a stop when he bumped into the hammer.
“Fuck it,” Sam mumbled, shaking away his blurry vision and wrapping his hand around the handle. Thor stopped short, gaping at Sam as he watched the power bouncing across Sam’s skin as he stood.
“You gotta be shitting me!” Tony yelled from where he was helping Steve off the floor.
“Now, Jack!” Castiel yelled, blocking another blow from Wanda.
Jack’s eyes started to glow bright enough that they could be seen from the end of the hallway; he lifted a hand and uttered a single stop, sending a wave of energy through the hall. Everyone froze mid-fight except for Sam, Dean, and Castiel; Sam dropped Mjolnir laughing awkwardly before running towards Jack, followed closely by Dean and Castiel.
A tear opened, blanketing the empty cells in bright orange light as the tear rippled slowly; the light intensified momentarily when Rowena stepped through. Castiel glanced back at the Avengers, shooting them one more glare before he disappeared into the tear. Sam barely managed to toss his brother through the portal before stepping through himself.
“I’m sorry,” Jack announced before backing through the portal. The tear flared one more time before it curled in on itself, disappearing without a trace. The Avengers were all released as soon as it was gone, each of them stumbling under the sudden momentum that the kid had paused somehow. Steve was still sitting on the floor where Tony was kneeling, both men staring at where the five strangers had just disappeared. Bucky was helping Nat to her feet after she toppled forward while Thor offered a hand to Wanda, who was struggling to stand from where she fell face down.
“I need a drink,” Tony announced, still staring dumbly at the destroyed corridor.
The portal snapped shut as soon as Jack stepped through, and everyone let out a sigh of relief. Sam dropped into the nearest chair, dropping his head into his hands; Cas joined him, slouching down in his seat, visibility exhausted after using so much of his grace. Dean was still standing at the end of the table, staring at the space they just fell through, his lips slightly parted.
“Dean,” Cas hummed, tilting his head. “Are you alright?” Dean blinked a few times, slowly turning to face his best friend, a bright smile spreading across his face.
“Dude! I just fought the Winter Soldier and Black Widow!” Cas didn’t bother to fight the smile spreading across his face; he was too tired to act like Dean’s excitement wasn’t endearing. Rowena stepped up behind Cas’ chair, chuckling to herself as Jack vibrated with just as much excitement.
“I touched Captain America’s shield!” Jack exclaimed.
“I lifted Thor’s hammer,” Sam mumbled into his hands. “And Cas held off the Scarlet Witch.” Dean’s eyes widened, and his mouth fell open as he stared at his brother and then his best friend, barely containing his excitement.
“Our lives are fucking awesome,” Dean laughed, dropping into an empty chair, smiling at the ceiling.
