imagine gabriel pulling all kinds of pranks on sam and dean. dean tries to get him back but gabriel never falls for them. sam doesn't react at all and gabriel keeps trying and trying to get a reaction. until one day sam pulls some prank on gabriel and gabriel totally falls for it. but he's not mad, instead he just stares at sam like - holy shit i really love this guy.
OH GOD I FUCKING LOVE THIS BECAUSE IT MAKES SAM AND GABRIEL EQUALS IN THE WORLD OF TRICKING AND I SWEAR TO GOD NOTHING MAKES GABRIEL LOVE SAM MORE.
Oh god, and Dean’s trying all the stupid shit that he normally tries on Sam, and it’s total failures on Gabriel, and Gabriel even mocks him a little bit about it.
Which just makes Dean try harder and harder, and Sam just rolls his eyes and ignores all of it. Which intrigues Gabriel, so Gabriel keeps pranking Dean, but still, no reactions from Sam, and oh god, he wants to know why Sam isn’t reacting.
And it’s because Sam is biding his time. He knows if he’s going to get Gabriel it has to be subtle, and perfect, and also totally unexpected. Dean is treating Gabriel like a human, and Sam knows better than that.
So he figures out what he’s going to do. Figures it out and makes sure he sets it up.
He goes grocery shopping and comes back, and Gabriel is always begging him for skittles or M&Ms and sometimes he brings them back. Except, except THIS time, this time, he plans ahead. He takes a pack of skittles and carefully dumps out half and mixes in Reeces and M&Ms. He then reseals the package, and takes it with him to the store.
It looks brand new, if he does say so himself. So Sam comes back and he puts the bag on the counter as he unpacks normally. Gabriel is drawn by the sounds and he makes a pleased, happy noise at the sight of the skittles.
He has the bag open and a handful in his mouth in a few seconds afterward. Gabriel freezes after the first chew and stares at him, in eye-widening horror.
Sam just winks at Gabriel and keeps unpacking, unable to stop from grinning as he walks around the kitchen. Gabriel is still staring at the bag in horror and appreciation and then looks up at Sam, his face widening into a slow, wide grin. Holy shit, he loves that human.
