A/N: Swearing warning

It had snowed a whole foot in Lebanon, Kansas, and Cas and Jack were freaking out.

You see, Jack had never experienced snow before. Never seen it before, didn't know what it was, or what to do with it.

Cas knew what snow was. He loved it. Dean had explained it to him a few years back, and while he still did not understand the concept of snow angels or why three snowballs on top of each other made a snowman- he still loved snow.

So Cas and Jack were very excited to inform Sam and Dean of the weather when they noticed the ground.

"SAM!" Jack pounced on the moose like a child on Christmas. "There's stuff outside! And it's white and it looks fluffy and Cas said it's called snow! What's snow? Why do we have snow? Cas says it's really fun- why is snow fun? What are snow angels? Do we hunt those? Is an army of snow angels going to attack the town? SAAAAAAMMMMM!" The hunter blinked at him.

"Um," He rubbed at his eyes. "Coffee. Then questions."

"Okay, I'll go see if Cas has gotten Dean awake yet!" Jack bolted out of the room.

Cas knew better than to startle Dean awake. The guy would scream and pull a gun on you. Dean was a bear in the morning- Cas would know- and he was to be carefully roused. 

So the angel crawled into bed next to a sleeping Dean and wrapped his arms around him.

"Dean," He whispered into the hunter's ear, his eyes wide with excitement.

"Hm?"

"You need to wake up."

"Mph."

"There's snow outside."

"So?"

"So Jack has never seen snow. He doesn't know what it is."

".....Please tell me he's not going to ask about snow the same way you did."

".....I don't know what you mean."

"...Sure. Okay. I'm up."

"Really?"

"Yeah," Dean opened his eyes and Cas grinned.

"Great! I'll go make coffee; you and Sam will need it."

"Let me guess- Jack was sent to wake up Sam."

"Yep."

"I know I should feel sorry for the moose, but I don't."

"I know."

******

Ten minutes later, the Winchesters were sipping coffee as Jack chatted about snow and they answered his questions.

"I don't understand why snowmen require carrot noses," Cas declared. "Human noses rarely resemble carrots."

"It's because of Frosty," Dean explained.

"I don't understand him either. How can a magic hat bring a snowman to life? And if it did, then it's probably because the hat is a cursed object, and the snowman's existence would be forever miserable because it was never meant to be alive."

"It's just a kids story, Cas."

"But a snowman isn't even shaped like a real person! If it came to life, it wouldn't be able to walk, I doubt sticks would make good arms- it'd be like that Teddy bear you encountered, and it would most likely beg for death, just to put out of its misery. That wouldn't befriend children, it would traumatize them." They stared at him.

"Cas, you just shattered my childhood," Sam admitted.

"Mine too." Dean agreed. "I mean, I always wanted to gank Frosty, but not like that."

"....Can we go play in the snow now?" Jack asked.

"Get a coat on and sure." Dean offered.

"Dress warm, it's cold outside." Sam said as the kid ran out of the room.

"I really can't stay," Dean sang, grinning.

"But baby, it's cold outside," Cas replied in his deep voice.

"NOPE," Sam walked out.

"I gotta go away," Dean set down his coffee as Cas stood up and rounded the table.

"But baby it's cold outside."

"My mother will start to worry," Cas wrapped his arms around Dean and sat in his lap.

"Beautiful, what's your hurry?" Dean laughed, pressing a quick kiss to Cas's lips.

"You know that song has become extremely controversial, right?" Cas reminded him. Dean raised an eyebrow.

"Does it look like I care?" 

******

The four of them were outside the bunker, in the snow, an hour later. Jack, clad in even more layers than the average Winchester, faceplanted into the snow and burst out laughing.

"You bundled him up like the kid from A Christmas Story," Dean commented. Sam shrugged.

"At least he's warm." He declared. "Cas must be freezing." The Winchesters were in their usual layers, but Cas had slimmed down to a T-shirt and jeans. No shoes or socks, no coat. He was tracing patterns in the snow with his bare feet, looking surprisingly comfortable.

"Angels don't get cold, stupid." Dean reminded him. Sam glared at him, and promptly shoved a handful of snow down Dean's shirt. Dean yelped and jumped, grabbing another handful of snow and pelting Sam with it.

A snowball fight erupted between the two brothers immediately after.

"What are they doing?" Jack asked curiously, slipping off a few jackets while Sam was distracted. He knew it was cold, but he wasn't, so why not ditch a few layers.

"That's a snowball fight," Cas explained. "Although they fight dirty." Jack grinned.

"Can we join them?" Cas thought for a second.

"Yes. Yes we can."

So Jack and Cas started pelting the boys with snowballs until an all out war erupted. Dean made a huge snowball and climbed up on a mound of snow behind Cas. The angel remained oblivious, a snowball in jhis hand as he debated whether to hit Jack or Sam.

And then Dean launched up, smashing the snowball down on Cas's head.

Sam and Jack gaped in shock, and Dean fell to the ground, howling with laughter as Cas blinked and brushed the snow off his shoulders, completely unfazed.

The snow fun continued as Sam and Cas made snow angels, and Dean and Jack started making a snowman.

"You know," Jack began. "Claire taught me a song related to snow."

"She did?" Dean raised an eyebrow. "I didn't realize you knew Claire." Jack shrugged.

"We text sometimes. She likes to check up on you guys, but refuses to actually admit it, so she asks me instead. I send her pictures of Felix, and she sends me videos and stuff. And one of the videos had some skeleton guy singing while he was surrounded by snow."

"Huh," Dean offered. "Do you remember the words?"

"Yeah."

"Then sing it."

"...Really?" Dean shrugged.

"Go for it. Sam and Cas are used to hearing me blurt out Metallica at all hours of the day. They might appreciate a change in singing voice." JAck thought for a second and then smiled innocently.

"Okay." So he got up and grabbed a couple handfuls of snow, throwing them up in the air as he started to sing.

"The fuck!" Dean choked on air and started half coughing, half laughing. Jack NEVER swore. 

"The fuck!" Jack went on innocently. "The fuck is in the air? The fuck! There's white shit everywhere," Cas and Sam stopped, staring at him.

"The fuck! I must be fuckin' baked and this shit's prolly fake, the fucking hell did I just take- the fuck!" Cas, Sam, and Dean had no words as Jack continued to dance around, belting out the song.

"The fuck? The fuck? There's something fucking wrong. The fuck? These bitches singing songs, the fuck! The streets are lined with sketchy creatures laughing, why the fuck are they so happy? Holy hell these things are fucking creepy, the fuck is this? The fuck!"

"It's really fucking awkward, fucking dancing all around, you think they'd have a guy to get this white shit off the ground, It's really fucking messy, Shit! I think my shoe is broke, I should've known to stay inside and just had one more toooooke....."

He stopped, glancing back at their shocked faces.

"Cas, your daughter corrupted the kid!" Dean declared.

"Shut up, Dean, she's your daughter too." Cas countered.

"Say who?"

"Says EVERYONE."

"Where did you learn those words?!?" Sam demanded.

"Claire," Jack said innocently.

"Do you even know what that means?" Sam questioned. Jack thought for a second and then slowly shook his head. "....Don't repeat that again."

"Okay."

"No! Do it again!" Dean retorted. "I wanna film, that was glorious."

"DEAN!" Cas and Sam snapped.

"Oh, like you didn't laugh your asses off." Dean declared. "That was freaking hilarious."

"No more parody songs for you," Sam proclaimed. Jack shrugged.

"You should be Jack Skellington for Halloween." Dean said. Jack frowned.

"Who's that?"

"Who's- OH MY GOD, we're watching that movie. NOW."
