Author's Note: I love it when headcannons come true. Do not read my Author's note at the end of this if you don't want spoilers for 09x04 Slumber Party.

Disclaimer: Not my stuff.

Warnings: I named Cas's cat Gabe, even though it's a female. Do not think I've made Gabriel show up through magic and stuff.

"This is ridiculous," Castiel said as he watched Dean show off his Halloween costume in front of him.

"No it's not," Dean said, shoulders slumping a little. He had been hoping that after the last couple of hunts Castiel would feel like they deserved a little break.

"Grown men don't go around trick or treating." Castiel said insistently. He crossed his arms and leaned against the back of the couch. Sam walked in and sat on the armrest of the couch.

"Well, we do alright?" Dean said adjusting his cape a little.

"No we don't, this is the first time since—"

"Can it Sam," Dean said jabbing a finger in Sam's direction. Sam rolled his eyes and replaced his ginger wig.

"Can I at least choose my own costume?" Castiel asked as Dean made Sam stoop down (just a tad more, the couch adds height he claimed) so he could adjust the wig.

"No, I already got you one; it's hanging in your room,"

"Why is it in my room and not in ours, I stay there most of the time anyways,"

"Because, I didn't want you to see it, Gabe better not have gotten anywhere near it."

"She wouldn't do anything to it Dean,"

"Gabe would tear it apart with his sharp-ass claws."

Castiel grumbled all the way to his room and Dean followed giddily behind him. Sam chuckled and went into Aziraphale and Crowley's room to help Crowley help Aziraphale with his costume. He figured it would be less of an explosion there.

"Crowley these stupid things aren't going on right, and look they're all askew,"

"Stop fidgeting angel. Thisss damn headband issssn't staying put,"

"Oh boo-hoo you terrible old snake, why do I have to go like this?"

"It's ironic,"

Sam stepped into the room.

"You guys sound like you need help?"

"Dressing a fallen angel like an angel is NOT ironic," Aziraphale said tugging at the too short white robe he was forced into wearing.

Crowley smirked behind him in his red suit and fake horn headband.

"I don't know, I think it's cute you guys have a couple costume,"

"A couple costume?"

"Yeah, it's a costume that when you wear it with your significant other makes a lot more sense than just wearing it on your own,"

"In this case, Zirah, we're an Angel and a Demon,"

"Yes but how is that any different from who we really were? I thought Halloween was for dressing up as someone you're not?"

Crowley deadpanned. His angel was right. He looked to Sam for help.

"Dressing up is for kids?" he offered.

"Yeah," Crowley said, "That's right, dressing up is for are grown men or men-shaped beings. We don't dress up, we dress as ourselves."

"So then why is Sam dressed like-"

"Sam is young enough to dress up,"

"And what about Dean? And Castiel?"

"We are millennia old beings. No matter what age your body thinks it is. They aren't millenias old, they're just babies really."

"Cas is," Aziraphale pointed out.

"Cass is… Dean's mate, they need to have a mate costumes."

"Fine,"

"Oh no, no no no no no, no no, no, no, no. No, no, no no, no."

"16 no's?"

"I'm not wearing that Dean,"

"Aw, come on babe,"

"No. Where is Gabe? She can destroy this costume, I am not wearing it."

"I thought you might say that."

Almost as if summoned, Gabe padded her way into the room.

"Gabe, destroy,"

Gabe looked at the white fluffy mess on the hanger and out popped her pink tongue almost as if licking her lips.

'Gladly master,' she said extending and retracting her claws.

"Wait Gabe, let me give Cas his other option,"

Gabe sat and licked her paws, purring contentedly.

"Either you can wear the Angel costume that Crowley and I worked very hard to put together. Seriously, no one was selling any so last minute and we had to go to ten different stores looking for the halos. Or, you can be the Robin to my Batman,"

Castiel thought for a moment before answering/

"No."

"No to what?"

"Robin, that's much too 'chick flicky' especially for you Dean. I will wear the angel costume, but do not make fun of me. I remember how I looked when Heaven first issued those types of gowns, back when the humans first fell and there was no armor to protect ourselves with… Or suits…. I can honestly say, they do not flatter me."

"I'm sure they do flatter you Cas"

"You are sorely mistaken,"

They heard knocking on the bunker door and Dean smiled.

"That must be Charlie, oh, you are going to love her Cas,"

Dean went to the door and answered.

"Hey Dean," She said extending her arm out for him to cut.

"Hey Charles," Dean said after she passed and he let her in

"Nope, I was Charles Xavier last year,"

"Ah, so this year instead of going bald, you'll go black?" Dean asked fingering the wig.

"Charlie!" Sam interrupted as he walked somewhat clumsily over to her.

"Hey Samwise Gamgee!"

"Right, hey Frodo,"

"Hobbits," Dean smirked rolling his eyes.

"I still wish you'd let me be Frodo, this wig is hot,"

"It's cold outside. Besides, first of all, you're too tall, second, you name is already Sam,"

"Well then, why not Dean?"

"It's more ironic with you Sammy,"

"Sam"

"-wise Gamgee," Dean finished.

"Hey, did you ever get the angels to agree to dressing up?"

"We did actually."

"Great, I'm going to need a picture with them,"

"Why?"

"Um, Charlie's Angel's ring a bell?"

"Oh," Dean said realizing Charlie must have had this planned. "Nice,"

Crowley walked out of the room

"Well, aren't you a handsome Devil?"

"Why yes, thank you, you must be Charlie, it is a pleasure to meet the sister these boys never had,"

Castiel and Aziraphale came out of their rooms wearing slightly different costumes. Castiel's robe was more modest (only by the barest inch of fabric though).

"Here, videotape this." Charlie said tossing her camera at Sam.

"Good evening angels," Charlie said hardly able to contain her glee.

"Good evening Charlie,"

The rest of the bunker's occupants burst into laughter.

"Hey wait," Aziraphale said suddenly "How do a masked vigilante and an angel go together?"

Robin was putting the last touches on her popcorn balls when the doorbell rang.

"Coming," she yelled as she scurried out of the kitchen. She picked up a bowl of assorted chocolates and she straightened out her witches hat.

"Well what do we have here?" she asked opening her door.

It was a group of adults actually. One Batman, one Devil (or angel pimp?), two very unamused angels trying in vain to pull down their robes (or maybe angel prostitutes?), one very feminine Frodo, and one giant of a Hobbit she would soon find out was named Sam (or maybe he was dressed as Samwise Gamgee?).

"Trick-or-treat!" the pimp, Frodo, giant Hobbit, and Batman said. The angels sort of just stood there unsure of what to do. She laughed and placed a generous handful of chocolate into each of their bags (because really, when adults go trick-or-treating, if they get a few candies, it's luck. If she didn't give them a lot of candy who would?)

"Now Angels," the two angels looked up in alarm, "You didn't say the magic words,"

They looked confused and one cocked his head adorably to one side.

"I'm sorry, they're from out of town, WAAAAAAY out of town. They've been brought up very, very religiously and hardly know what to say,"

"Just say trick or treat you guys." The tall hobbit offered.

"Trick-or treat?" they asked in unison. Robin smiled and dumped some chocolate into each of their bags.

"Wait right here while I get you some popcorn balls."

The group left the house munching a popcorn ball and a nice somewhat heavy bag in their hand

"Why would they just give out free candy?"

"I've honestly no idea Cas, they just do, it's tradition."

"So, we spend money on costumes, they spend money decorating their house and buying candy for strangers in costumes who they may never see again?"

"Happy Halloween angels," Sam said shrugging and walking up the path to a new house.

are you sure you want to see this?

Alright. So anyways, I had a headcannon of there being a garage inside the bunker I DID NOT EXPECT FOR IT TO BE FILLED WITH CARS. but yes, what they showed on 09x04 is basically how i imagined it. My goodness, it feels amazing when head cannons are fulfilled. I always wanted a garage, ever since Charlie visited the bunker in her cute yellow car and all i could think was, 'dang, the men of letters need somewhere for Dean to put his baby or it'll get all dusty.' So then I wanted to write a chapter for that, and I did. but it's not coming up for another chapter or so. Anyways, also, DID YOU SEE THE HUGE LIGHTED TUNNEL AT THE END OF THE EPISODE WHEN THE BOYS REOPENED THE DOOR!? IT'S THE MOTHERFUDGING BATCAVE I TELLS YA! see you in a few days hopefully.
