Dean Winchester stood at the stove in the bunker's cavernous kitchen, humming Eye of The Tiger to himself. The boys had just returned from a successful vamp hunt, and Dean was riding the high out, flipping burger patties and enjoying the occasional hiss of oil as it sizzled in the pan, while Sam stood at the counter slicing salad to go with the burgers. Rabbit food didn't particularly appeal to Dean, but if Sam was happy to chop it up, hell, HAPPY, period, then Dean wasn't going to make a fuss about it.
Easing the spatula under the first beef patty, Dean flipped it enthusiastically, splashing oil over the stove top and up the wall; he winced when a few large drops of oil landed on his arm, then wiped it away with his sleeve before Sam could see and start going all mother hen about it, making him run his arm under cold water or something stupid like that. Ignoring the angry red welts now marking his arm, Dean flipped the second patty, more carefully this time, taking a deep breath and inhaling the delicious greasy smell. Mmmmmm he could get used to this...
Sam studied the piles of burger ingredients, a feeling nagging at him that he was missing some key element. Lettuce, tomato, cheese, mustard, mayo, ketchup, hamburger buns - Dean had talked him out of adding beetroot, so that couldn't be it.
Sam frowned, thinking hard, and then it came to him a fleeting memory of something Dean had shouted to him a million times over the years - EXTRA ONIONS! Damn it. He'd forgotten Dean's onion rings. Sam abandoned his chopping board and hurried to the pantry, groping in the dark depths at the bottom of the cupboard and and brushing away cobwebs before he managed to put his hands on some onions. Yes! Lucky! Dean would never let it go if he forgot the onion rings... Striding back over to the kitchen counter with a smile tugging at the corners of his mouth, Sam started carving the onions into thin slices, just the way his brother liked it.
"Patties are done!" Dean declared proudly as he took a swig of his beer.
"That's great Dean." Sam replied. "We just need some plates then."
Just as Dean was reaching for the plates, there was a sudden BANG! from upstairs and both Winchesters jumped, startled.
Dean dropped the plates he was holding and as they shattered on the floor, Sam slipped with the knife and sliced his hand open. The Winchesters both swore in unison, swivelling toward the doorway, guns trained on the stairway as the sound of footsteps echoed through the foyer...
