It was Cas's idea.

A double date. Destiel and Sabriel, out to dinner, with no one trying to murder each other. A calm, peaceful meal between two sets of boyfriends. Two set of brothers. Four friends. 

Simple, for average people. But we all know that the Winchesters are not average people.

"This is so stupid," Dean complained, fixing his shirt. 

"It's not stupid," Sam objected, rolling his eyes, and adjusting his own clothes.

"Yes it is. We've NEVER done this. Why would we ever do this?" Dean paused. "Wait, why HAVEN'T we done this before?"

"Because if we ever decided to double date with a pair of girls, we'd spend the whole time forcing the crazy one to like the other one."

"What?"

"You'd flirt with the hot girl and ditch me with the friend, and I in return, would also flirt with the hot girl and try to ditch you with her friend."

"Yeah, but I'd win."

"No you wouldn't."

"Yes I would." Sam rolled his eyes and Dean groaned. "Why did we agree to this, Sam?"

"Because Gabriel and Cas thought it would be a good idea."

"Why do we listen to them?" Dean grumbled.

"Because they're sleeping with us." Sam said bluntly. Dean paused.

"....Can't argue with that logic."

"No you can't."

"Okay, let's do this."

****

"Okay, I get the whole Double Date thing, but why do we have to get dressed up?" Gabriel complained.

"Because it's a fancy restaurant, and in fancy restaurants, you get dressed up." Cas explained. "And according to Dean, you're also supposed to get dressed up for dates too."

"Screw that- I've shown up to dates with Sam in a onesie before."

"...And somehow, I don't think Sam appreciated that."

"Well, he was in his pajamas, so I think we were equal."

"Where did you even go on that date?"

"A Broadway play."

".....How-"

"I have my ways, and my Sammoose only gets the best." Cas sighed.

"Can you just promise me you'll behave?" He questioned.

"I always behave."

"NO, you don't. And I just want dinner to go over smoothly, so I'd appreciate it if you didn't do anything that offended Dean."

"Uhhh, Cassie? You do realize that I'm showing up this thing under the title of Sam's boyfriend, right? No matter what I do, it will offend Dean and he will want to shove me off a cliff."

"Why do you think I picked a restaurant that is nowhere near a cliff?"

"Dear Dad, you've thought this through?"

"I thought everything through, because I know what happens when you and Dean end up in the same room together."

"Well hey, Sam can keep me under control, and it'll be your job to control Deano."

"Pretty sure both of you are two man jobs."

"Tell you what, Cassie. Since it means that much to you," Gabriel smirked. "I'll be a little angel."

"This is not the time for sarcastic humor, Gabriel."

"Yes it is- we're going on a date with Tweedle-Dumb and a sexy moose."

"Tweedle-Dee and a cuddly cowboy."

"This is gonna be fun."

****

The four men met up at the restaurant, and separated into their individual couple pairs.

"Dean," Cas nodded, looking a little stressed.

"Calm down, angel," Dean advised. "It's just dinner, we'll be fine." Cas looked unsure. "I'll behave if Gabriel does."

"Okay, so then no one's gonna behave." Cas declared. 

"Relax. It'll be fine."

"If you say so..."

"Hello Samsquatch," Gabriel declared, waggling his eyebrows. Sam fought back a grin.

"Gabe," He offered. "You should wear suits more often. They look good on you."

"And you, Sammy-candy, should wear less clothes." The moose rolled his eyes.

"You know that's the exact type of comment that's going to piss Dean off, right?"

"So what, I can't flatter my boyfriend at all tonight?" 

"Of course you can," Sam insisted. "Just.... Try to be subtle." Gabriel snorted.

"Well, you know what subtlety gets you? Ten seasons of built up tension and no smooching. No thank you." Sam grinned.

"You're ridiculous." He declared. Gabriel smirked.

"That's why you love me," He retorted.

A waiter led them to their table. It was a simple booth. Sam and Gabriel took one side, and Dean and Cas sat across from them.

"Can I start you off with something to drink?" He asked.

"Beer," Sam and Dean said in unison.

"Vodka." Cas said bluntly. "And lots of it."

"Whatever drink is most likely to give me diabetes." Gabriel insisted. The waiter backed away slowly, and Gabriel smoothly slid his arm around Sam's shoulders.

"So," The trickster commented. "Double date.... Fun." Dean glared at him, and Cas glared at Dean in return.

"Sooooo," Sam said awkwardly. "Cas! Why the vodka? Usually you're more of a water person."

"I assumed that the least painful method of getting through a dinner with all three of you would be to consume copious amounts of liquor." The angel offered.

"Well, at least the two alcoholics have found each other." Gabriel declared.

"Gabe-" Sam muttered.

"So! Gabriel," Dean offered. "How's Asmodeus doing?" That one earned him a bitchface from both members of Sabriel.

"I don't know," Gabe countered. "How's Mikey?"

"Shut your piehole."

"You shut yours first."

"ANYWAYS!" Cas tried to think of a safe topic. "Nice weather today."

"Yes, bright and sunny." Sam agreed.

"Reminds me of a Tuesday," Gabriel said dreamily. "We should've eaten at a diner."

"And this is why I thought this was a bad idea." Dean muttered.

"Yeah, well, no one else was pulling anything out of the idea book, so here we are." Cas insisted.

"Wait- Dean- you KNEW about this?" Sam questioned. "I thought you hated the idea of a double date!"

"I do." Dean grumbled.

"Then why did you agree to one?"

"Because I had to admit that it was the easiest option."

"Easiest option for what?" The waiter returned.

"Don't worry about it." He said sharply.

Copious amounts of alcohol later, dinner was much more enjoyable.

"Really?" Sam raised an eyebrow at Gabriel, who, instead of ordering a normal dinner meal, had gotten Belgian waffles with so much whipped cream, you couldn't even see the breakfast food.

Cas and Dean had opted for burgers, because Cas like burgers, and Sam, ever the vegan moose, stuck to salad.

"Really." Gabriel confirmed, his eyes gleaming. "Oh! Here's an icebreaker for the table. Hottest stripper you've ever seen- go!"

"That's-" Cas started.

"Saphira Shimmer," Dean said instantly. "She worked at this little club in Nevada- that girl had it all."

"Are we really-" Sam asked.

"Roxanne." Gabriel insisted. "Worked at a club in Buenos Aires. It was decades before either of you boys were alive, but oh, did that girl have style and sass."

"This is ridiculous-" Cas offered.

"Probably Erica Lazuli." Sam admitted.

"No way," Dean insisted. "Her?"

"Hey, you've got your pick; I've got mine." The moose declared. "She was a dancer at this bar in Louisiana. Short but sexy."

"What about you, Cassie?" Gabriel pressed. Cas blinked. He had no real encounters with strippers.

"....Chastity was nice." He said quietly. Dean choked on his drink and burst out laughing.

"Who's Chastity?" Sam and Gabriel demanded. Dean only laughed harder.

"She worked at a den of iniquity that Dean took me too once." Cas offered. "She hit me with her shoe and yelled at us, and we got thrown out. She was quite pretty though." Dean could barely breathe; he was laughing so hard at the memory.

"....I'm gonna need a better explanation then that." Sam admitted.

"Me too." Gabriel agreed.

"I took him to a brothel!" Dean burst out. "And he told the woman that he was sorry her father ran out because he hated his job at the Post office!"

Gabriel burst out laughing, and Sam facepalmed. 

"Only Cassie," Gabe grinned.

"I don't know why you find my every encounter with the female species amusing." Cas declared.

"Because you around women is like Sam around Clowns," Dean explained. "You're terrified, and that makes it amusing to the rest of us."

"Sam doesn't like clowns?" Gabriel asked deviously.

"Dean, why have you betrayed me..." Sam muttered. 

"NO WAY." Gabe proclaimed.

"It's true." Dean grinned. "He used to be so terrified of the Joker, I'd tell him I was Batman so that I could defeat him." Cas smiled.

"I hate clowns," Sam admitted. Gabriel started humming circus music, and Sam stamped on his foot under the table. Gabe only smirked at him.

"So Cassie, Deano," The trickster asked. "Why did you two come up with the ingenious plan for a double date?"

"I wanna hear this too," Sam agreed. "We've been dating in separate pairs for years- why have dinner together now?"

"Exactamundo." Gabe offered. Cas and Dean exchanged a glance.

"Do you want to tell them?" Dean asked.

"Sure." Cas agreed. He sighed, taking Dean's hand in his.

"Now I'm scared." Sam admitted.

"Who's dying?" Gabriel demanded.

"If you're breaking up, I'm going to shoot myself." Sam proclaimed. Gabriel gasped.

"Oh my freaking dad, is Dean pregnant?" Sam burst out laughing.

"So childish." Cas commented.

"You know, Sam is normally a very serious person," Dean offered. "And then Gabriel walks into the picture, and my brother's maturity level drops thirty years."

"It's amazing."

"Okay, okay, sorry." Sam collected himself. "What is it?"

"We'll behave, we swear." Gabriel insisted, still smirking. Cas and Dean exchanged another glance, smiling at each other.

"Dean and I are getting married." Cas announced. Gabriel's jaw dropped, and Sam's eyes widened.

"Seriously?" The moose questioned. Dean nodded, grinning.

"Seriously." He confirmed.

"What." Gabriel gaped, and Sam jumped up from his seat with a fanmoose squeal and hugged his brother.

"FINALLY!!" Sam declared. "It's only been like twelve years I've been waiting for this!!" Dean laughed and hugged him back.

"Why." Gabriel questioned.

"Because I love him." Cas admitted.

"But he's a moron!"

"He's my moron." Cas smiled. 

"Cassie," Gabe whined.

"Gabriel," Cas insisted looking unsure. "We both know the other angels won't be happy about this."

"Damn right they won't be."

"So I need you to have my back on this. I don't care what your personal opinion is, but you're the only brother I can trust anymore, and I need the ally. Can I count on you?" Gabriel smirked.

"Aw, shucks, Cassie. You know you can always count on me." He smiled. "I'm happy for you." Cas grinned.

"Thanks Gabe."

"Anytime, brother." Gabriel turned his attention to Dean. "And YOU."

"Gabriel." Dean deadpanned. Gabe stood up and pointed a spoon threateningly at Dean.

"You hurt my baby brother, I'll smite you." He warned. Dean smirked and stood up, pointing a knife at Gabriel.

"Right back at you." He warned.

"Alright, sit down, sit down." Sam ordered. "Before you both get us thrown out for murdering each other."

"I'll win." Gabriel proclaimed.

"You have a spoon." Dean insisted.

"Yeah. And you have a knife. That's just an angry spoon."

"What?" Sam and Cas facepalmed.

"You sure you want to marry into this?" Sam asked.

"I'm sure." Cas grinned. "What about you?" Sam eyed the standoff worriedly.

"Well, there no way I'm getting out of it." He admitted. "Might as well go all in."

"Exactly." Cas agreed.

"I'll stab you." Dean warned.

"And I'll Connecti-CUT you." Gabe shot back.

"To our brothers," Sam offered, raising his glass.

"To our brothers." Cas replied, raising his own. They drank, and Gabriel launched over the table, tackling Dean to the ground.
