Snow
It started over the simplest thing and Sam would blame Gabriel for it later.
They'd been joking arguing about something, Christmas chocolate, and Gabriel was praising it while Sam was less impressed by it. In the middle of their light hearted, and actually rather flirtatious, debate Dean had snapped at them to shut up. Sam was willing to bet it was because Castiel had to deal with some heavenly business. But either way Dean stormed out of the Impala, slamming the door behind him. Gabriel smirked at Sam and followed.
Sam was still in a rather mischievous mood, so when they got out, he grabbed a handful of snow.
How Gabriel knew there was a snowball flying towards him was beyond Sam, but in any case he ducked. He turned to grin at Sam, when the snowball hit.
Right in between Dean's shoulders. He whirled, to see Gabriel still ducked and Sam with a guilty look.
The next thing Sam knew he was dodging snow balls from Dean, while Gabriel laughed.
Until one hit him.
At first Gabriel was on Sam's side, throwing snow back at Dean, then he hurled one at Sam and everyone was fair game. Sam hadn't grinned or laughed like this in a long time as he tried to dodge both Dean's snow.
"Ow!" Gabriel yelped, "that one had ice in it!"
"Whoops!" Dean called back, ducking as a snowball flew at him.
Sam had darted behind the Impala to stock up on ammunition, temporarily taking their attention off him. He stood up, and signaled to Dean to ignore him, while creeping up on Gabriel.
"Oh come on, what kinda throw was that?" Dean taunted, standing on the stairs leading up to their rooms.
Gabriel's retort became a startled yelp, and he about jumped a foot in the air as Sam dumped two handfuls of snow down his back.
"Sam!"
Sam laughed and darted back towards the Impala to restock, as three snowballs pelted his back, still laughing.
Sam ducked and began returning fire, unable to stop grinning.
They were running out of snow though, and Sam had just thrown his last snowball at Dean when it happened.
Castiel appeared, his back to Sam and Gabriel, and thus, was hit in the back of the head.
Sam flinched while Gabriel cheered.
"Damn, that was just…"
Castiel slowly turned around, and Sam quickly sank down behind the Impala, eyes darting around.
Gabriel crossed the parking lot to hide with him, smirking slightly, "geez Sam."
"It was an accident!"
Gabriel ruffled his hair, his own was dusted with snow, "oh I know, but that was hilarious."
Sam smiled back, "I should probably apologize though."
Gabriel shrugged, and pulled him over for a warm kiss.
But as nice as the kiss was, Sam didn't miss when the snow slid down his back.
