I've had this up on my ao3 account for a month now and forgot to put it up here as well. I only have two parts written as of now because I'm finishing up the sequel to Comrades and Brothers at the moment. Once I'm done with that I'll go back to this story and my SPN/SV crossovers. Let me warn you this is different from the typical HP/SPN crossover fics you see on here. Gabriel will only be known as Loki so no spoilers to season 4 and beyond in SPN. There is no romance. Harry is in his first year. The Winchesters have wings. Harry is just a wizard. Etc. Etc. If you want to read this in AO3 format, just copy and paste this but put an actual period: archiveofourown(period)org/works/1082493/chapters/2176272

Part 1

"Tell me, Dean, you like Champagne? Or frisky women? Or how 'bout both at the same time?" The trickster asked with a smirk on his face, snapping his fingers and suddenly Dean was on stage, sure he was dreaming, sure the trickster had been snooping in his head and just pulled everything Dean daydreamed about with a single stroke of motion. The strippers closed in on Dean just as Sam darted out of the shadows with the stake, aiming for the trickster's heart.

Yes, yes, do it, Sam come on, do it, Dean chanted in his head. The trickster, however, seemed to have counted on Sam's lunge and with a snap of his fingers, he disappeared only to reappear a few seats down. Damn it. Sam stumbled and swiped at air as Dean growled in frustration. He ducked away from a stripper with a devil's headband that suddenly made to grab him. He dodged a few aimed kicks and rushed down the stairs. Plan B, then. Rush the trickster like a bunch of psychos.

The trickster was sitting comfortably in his seat like he had all the damn time in the world, which made Dean angry. It was like he didn't view Sam or Dean as a threat. The trickster grinned and snapped his fingers again and suddenly Sam was holding a bouquet of fucking flowers. Dean paused to stare at it, bewildered. Sam huffed in frustration and threw it to the side. It was pretty useless now. Dean looked back at the trickster to see him laughing, a bucket of popcorn in one hand now. He chucked a few at Dean, still amused as hell.

"Come on, guys, lighten up a little," he said, chowing down on fucking popcorn. Seriously. What the hell was with this guy?

"How are we supposed to lighten up when you hurt those people?" Sam demanded, bitch face and all—well he called it a scowl but it looked pretty bitchy to Dean.

Trickster frowned as he popped in more popcorn into his mouth. "Those people got what they deserved you know," he said it all casual like.

"You made a guy fall out a window," Sam said.

Dean was sure Sam would have better luck trying to reason with a brick wall all the response he was getting out of the guy. "Not really my fault the poor bastard couldn't take a joke."

"You made him see a dead chick," Dean chimed in. "And what about the kid you turned into some freaky alien's bitch? What's the excuse there?"

The guy grinned wide at that one, like it was one of the funnier pranks. Which it really wasn't. Fucking creepy if you asked Dean. "Dude, come on. Aliens! That was funny, you have to admit," the trickster said in between huffs of laughter. But Dean and Sam weren't laughing. Because no, it fucking wasn't funny. Not really…maybe at first, a little…when the kid rehashed it to them. Dean scratched his head when he realized he had laughed at the kid. Jesus. Dean really was a dick.

"Okay, fine. They weren't funny. I get it. People got hurt and blah, blah, blah. I'll leave then," the guy said with a long, almost dramatic sigh.

The whole theatrics was starting to get on Dean's nerves. "And let you go on hurting people? Sorry, Chuckles. No can do."

The trickster got up and looked pointedly at the two weaponless hunters, then the discarded bouquet of flowers. "And how do you propose to kill me without your little stick?"

"You really think we would come here hunting down a demigod without a backup plan?" Sam asked. "Come on, Loki."

Loki glowered as Sam revealed his name. Dean was impressed, hadn't really thought much on Bobby's plan. Supposedly demigods had a lot of power, could conjure almost anything, stuck with illusions mostly though. At least Loki, in particular. Fucking tricksters, man. As if on cue, Bobby came running in from the back and Loki turned in surprise.

"Now, Dean! Do it!"

Dean rushed forward, pulling out the extra stake he kept stashed in his jeans. He plunged the wood into…air. Dean toppled into the empty chair. What the fuck?

"Where'd he go?"

"You didn't think it'd be that easy, did you? Seriously, boys, I'm a demigod. Do I have to spell it out for you?" Dean rolled to his feet to see Loki standing on the stage, a woman on either side of him like he was some rich douchebag. He probably was now that Dean was thinking about, probably could conjure money up whenever he felt like it.

"Oh shut up," Dean told him, then spun around to look frantically at Bobby. He said this would work.

The older hunter scratched his beard, just as confused as Dean, maybe a little worried. Which wasn't good. He and Sam were relying on Bobby after all. It was his freaking idea. "Bobby, the hell do we do now?" It was never a good thing when Dean panicked. But it was even worse when Bobby didn't have a response. And Sam? Just standing and gawking? Yeah, real helpful there, man.

"You know, I got a suggestion for you guys since you seem pretty stumped," Loki chimed in cheerfully, too cheerful if you asked Dean. "How about a vacation? Hm. Hawaii maybe?" Then he snapped his fingers and suddenly…well, suddenly Bobby wasn't there with them, and that was kind of, kind of Dean's limit right there. Wide eyed and maybe a bit in shock, he wasn't so sure, he charged to the stage. Then…then, god, was this was weirdest case Sam and Dean ever taken up.

Then he kind of just froze, one foot on the step to the stage. Dean could move his eyes around, but his arms, and legs, all his muscles, they were just kind of stuck. "What the hell did you do to me!" was what he wanted to say. But he didn't, because he couldn't. What came out was more, "Mmphh, mmmphh, mmmpph mmphh!" or something like that.

Loki chuckled at him and Sam, who had been running after his brother came to a skid a few feet away. Eyes huge as he took in scene of his frozen brother sounding like he was talking through an invisible gag. By this point, Dean knew they were really, really in over their heads. Loki didn't seem to notice either their discomforts to the situation. He snapped his fingers and a table that looked like it had been snatched out of a high class restaurant appeared, lit candles and a vase of roses and all. He sat in the chair and gestured for Sam to take the other. Sam walked on stiff legs and sat down cautiously so they facing each other. It was like a bad parody of every romance scene in every bad soap opera Dean had ever seen on TV. He really wished he could move because his legs were going to be shaky by the time they were out of this and he really wanted to demand what the trickster really wanted from them.

"So Sam…what would you like?" Loki asked as Sam just sat there looking like a bewildered kid. Two menus popped up and Loki handed the extra over. He set his down and looked at Sam expectantly.

Sam awkwardly put the menu to the side. "Uh, nothing. Look, let my brother go and we'll let you leave."

Loki leaned back on the chair casually, propping his feet on the table. Suddenly a large cake appeared on the table like magic, one of those wedding cakes Dean was sure. Only this one was made of chocolate and had way too much candy sprinkled all over it. It made Dean's stomach lurch just looking at the damn thing. Loki swiped some of the frosting off with a finger and brought it to his mouth to suck at like a goddamn Popsicle. Bobby wasn't kidding about the sweet tooth.

"What if I don't feel like leaving now?" Loki asked after he licked his finger clean.

Sam frowned, bitch face back on. "You can't just keep killing these people, Loki."

Loki rolled his eyes as he swiped more chocolate. "Fine, no more killing then. You hunters are really sticks in the mud, you know that?"

"Let my brother go now."

"Okay, okay, no need to get your panties in a twist."

Dean staggered forward in sudden movement, catching himself on the stairs before he did a nice face plant on it. "At least warn a guy," he grumbled as he straightened back up.

Loki just grinned, a smudge of chocolate on his face that made him look oddly childish. "You know, you and Sam could use a break. From hunting all the big, bad nasties."

Dean snorted. "Thanks but no thanks, pal."

"If you say so." Loki said with a casual shrug. If Dean hadn't been so freaking tired, he probably would have thought it a bit odd the way the trickster was looking at his brother as Sam turned to head back down to Dean. The smirk was kind of out of place, one that was usually associated right before all the bad crap happened. "Say, Sam."

Sam turned at his name. "What?"

"What do you think of wizards and magic, oh and unicorns?" That was when Dean saw it, that weird gleam in Loki's eyes, the one that all the bad guys got before they did something diabolically evil. He darted out and grabbed Sam's arm just as Loki snapped his fingers.

The next moment had to be a dream or something. Dean was suddenly pushed away from his brother and was hurtling into the wall…which he was pretty fucking positive wasn't there moments ago. But there was. Lo and behold, it was like magic, just grew out of the ground in the auditorium. Dean looked around him carefully. No hold on, this was not the auditorium. This was, they were in some kind of closet, with a bed and a table and a light. Okay not a closet. Just a really, tiny bedroom. An elbow shoved into his side and fuck, couldn't Sam keep to himself for once? Dean shoved back and was met with a hissed, "Ow! Jesus, Dean!"

"Watch it then, asshole," Dean responded. He was getting sick of Sam's crap.

"Dude! Fuck! Why don't you take your own advice and keep your hands to yourself? Come on, Dean, this isn't funny!"

"You think? And what do you mean 'keep your hands to yourself'? I didn't touch you!"

"Uh, yeah, you did. Or am I just imagining something jabbing me in the rib?"

"Dude, that's not me! I swear!"

"Then what the…oh god, oh god, Dean, Dean, Dean…"

Dean turned around in exasperation. "What is it now…" Oh fuck. Were those…were…Eyes wide, nearly popping out of their sockets, Dean reached a slow hand out to, to prod the thing still jabbing at his brother. Holy fuck, they were real. Solid and real and god this wasn't happening. His gaze trailed up, up his arm, holy god, it was stretching to his back. He spun around trying to see where it was coming from. White feathers fluttered to the floor. Oh god, oh god. Dean froze in place, like a deer caught in headlights. These were…

"FUCK! OW!" Sam tugged sharply at a few feathers.

"Looks like…they're a part of you," he said in awe.

"Ya think? Wait, wait, wait, what do you mean 'a part of me'?"

Don't say it. Don't you dare fucking say it, Sammy, Dean thought frantically. But dammit Sam opened his mouth and said, "Dude, incase you haven't noticed, but you got ginormous wings growing outta your back." Fuck.

And if that wasn't goddamn enough, lo and behold, Loki popped right on in, strolling through the door with a lollipop and a lopsided grin. He tilted his cowboy hat and Dean almost thought he was going to greet them with a "Howdy, Partner". Instead he hopped on the tiny bed, laying down with his head propped on the pillows and his ankles crossed, looking at Sam and Dean like this was just an average day out. In the life of the Winchesters, Dean supposed it might as well be.

"Loki," he ground out, ignoring the new extensions protruding from his back, currently slapping his brother's face. Eat it, Sam, he thought darkly when he heard another indignant sputter.

Loki grinned from ear to ear. "Bet you're wondering what's going on right now."

"No. I'm more wondering how I can get close enough to stab you in the freaking heart."

"Oooh feisty. I always did like you, Dean-o," Loki said.

"Enough with the games, Loki," Sam said as he pushed the wing out of way for what must have been the seventh time. "Seriously, Dean, can you at least move?"

Dean grumbled as he stepped closer to the wall, giving his brother more space. Sam nodded his thanks and turned back to the demigod. "Look we said we'd let you go and we did so just cut to the chase and tell us what you want."

Loki frowned, then sighed. "Sammy, Sammy, Sammy. You hunters are so self-centered. Who said I wanted anything from you boys?"

Dean couldn't believe this guy. He gestured wildly around them and then pointed to the fucking contraption on his back he refused to acknowledge. "Hello!"

Loki glanced at Dean then to his latest addition, grinning when he caught sight of it. "Oh yeah. Like my gift?"

"No, I freaking don't! Take it back!"

"But Dean-o, they're gorgeous wings," Loki said looking affronted.

They certainly were not. Loki's gaze moved back to Sam. "What about you then, Sammy? Do you like my gift? You've always been the more polite one."

Sam scowled at the nickname. "It's Sam." Then, he paused, looking more suspicious. "And what gift?"

Dean swallowed, not liking where this was going. Especially with that gleam in Loki's eyes that made him look too much like a cat that just caught up with its dinner. Sam must have caught it too because then his eyes were widening and he was checking his back suddenly, looked kind of like a dog chasing its tail. Had this been any other circumstance Dean would be laughing his head off. Sure enough, he didn't need to turn a whole lot. Huge black wings, looked like Dean's really except his were white, were growing out of his back. It was kind of a gross process and Dean didn't really want to get into the details.

"Dude! Stop! Oh god, get rid of them! What the hell did you do?"

Loki grinned through Sam's panic, twisting the lollipop in his mouth. "I gave you both wings. No need to thank me." Then he sat upright. "Okay let's get straight to business then, shall we?" He paused to stare at the Winchesters, the smile dropped for a thoughtful frown. "You two stopped my fun so I decided, to make it even, you'll be my entertainment tonight. Welcome to my reality, boys." He extended his arms out and gestured to the small room they were in.

Dean scowled, crossing his arms. He did not want to be anyone's entertainment. Hadn't been in the cards. But he and Sam weren't holding the winning hand here, so grudgingly he had to play along. "So, what? Your entertainment include us standing around in someone's closet looking like a freak show?"

"Ever read 'Harry Potter'?" Loki asked suddenly.

Surprised by the change in topic, Dean shook his head. "Hadn't read it but I watched a few of the movies."

"Magic, wizards, werewolves, unicorns, hell it's pretty much up your alley, boys," Loki said.

"Except the unicorn part," Sam said.

"Whatever. What does that have to do with anything?" Dean asked.

"Why, everything, Dean-o. You're in it now," Loki said with a smirk. He leaned forward. "Now here's the first rule to the game, boys. It's actually fairly simple. You just gotta survive."

"And then you'll let us go?" Sam asked hopefully.

Loki nodded and produced a picture of a kid with dark hair and green eyes. He wore glasses. Dean thought he looked like any other normal kid, a bit nerdy, but whatever. Then he squinted. "Hang on. Isn't that the kid…"

"Yep. That's Daniel Radcliffe. In here, however, he's Harry Potter. He's your objective tonight."

Dean blinked. "What? Are we playing 'Call of Duty' or something? What do you mean 'objective'?"

Loki chuckled as he tucked the picture away. "What I mean, nimrod, is you have to protect him. You know, like make sure he doesn't get hurt, that stuff. Should be easy for you, Dean-o."

Dean scowled at the implication. "Okay, so what, we just survive and protect some kid, right?" Sam butted in before Dean could speak.

Loki nodded. "Got it in one."

"Okay. Great. Glad we got that cleared up. So mind telling us why we need these?" Sam asked gesturing at their wings.

Loki looked at him and then smirked. "Thought it'd be fitting seeing as how you two are going to be playing Guardian Angels. So why not?"

Fucking logic was messed up. Dean wanted to rip the guy's head off. "Take them back," he said through gritted teeth. "We don't need or want them."

Loki shook his head, the freaking bastard. "I can't even if I wanted to, Dean-o. Only way to get them off is to play and win the game. But cheer up, boys! They're not just pure decoration you know."

"Wha…wait, what? We can use these? How?" Sam asked.

"Jump and see," Loki said, wiggling his eyebrows. "'Guardian Angels' isn't just a fancy title I felt like giving out, you know. Anyways, look at the time, this is my cue to leave, boys. See you in about a year. Au revoir!"

"Wait! A year? You just said it was only for tonight!"

Loki grinned. "Have you forgotten already, Dean-o? You're in my reality. My reality, my rules. One year here is the same as one night out there." He tipped his hat and strolled out.

Dean rushed to the open door but the trickster was gone.
