Amos, you're quite possibly one of his favorite people on the planet right now. Or maybe just in dreamspace - but that doesn't matter, because he's picked up on the younger Winchester gunning for one of those sparklers, and he takes it with the sort of triumphant grin he gives Dean when he's either just proven him wrong or managed to get one over on him.

He's just short of sticking his tongue out him. Sam Winchester, you're old enough to know better, and you know it.

He lights his sparkler, and watches as it fizzles into life, eyes lighting up as though they hadn't already been filled with the sort of delight that can only come from doing something that he isn't supposed to be doing. "We'll be careful," he adds absently, twirling the firework around and around and watching the after-images left in the dark from the bursts of light.
