> And Dad won't mind if we're out just to watch the fireworks, really!
Unfortunately Dean's equally sure of the counterargument he posits in an increasingly irritable tone - “Yeah he will. Really”
It's amazing how Sam can miss the point entirely; maybe Dean didn't explain well enough. Monsters are real, and Dad fights them, and that's his job and he's good at it and so it's not dangerous for him. But they're still small (Sam's still small; Dean's old enough to take care of himself) and it's still dangerous for them (for Sam; Dean would be fine going out there alone, except that he's got an important job keeping Sam safe so he won't) and Dad's told them to stay in the motel room – behind the lines of salt he diligently checks each morning - where it's safe. Running around the car park in daylight is one thing. Going out in the dark is another.
He tries to concentrate on the film (which is really stupid; some Christmas-y thing about a ghost who doesn't realise they're a ghost who's come back to bug their stupid family, which doesn't really improve his mood because ghosts don't work like that and if they'd any sense they'd break out the salt and iron. Maybe there's a twist ending where the ghost eats the family to serve them right for being stupid) and when that fails on the magazine, which is out of date by a good few months but classic cars are forever, so Dad says, so it doesn't matter and he flicks through the articles looking for anything about an Impala he can put aside for when Dad gets back.
> Pleeeease?
Sam whines, and it's both hilarious and pathetic, and Dean turns to face him with what he hopes is a fairly decent parsing of Dad's I'm putting my foot down and that's final face, all raised eyebrow and nothing you can say will change my mind brow furrow, and there follows a battle of wills settled as these things usually are – with a staring contest until one or other of them caves with a fine, whatever and it's over. These are the arguments he doesn't mind so much, because there's no pressure to be clever, to try and convince Sam of anything other than that he's right, and he usually doesn't have to storm out and clear his head afterwards.
Doesn't look like Sam will be the one caving, though.
Goddamn it, Sammy. He looks so damn excited, and it's really hard to say no to that. And it wouldn't hurt, right? It's a public display, there will be other people about – normal people, and police and stuff even though Dad says the police are rubbish, that they try to do his job but suck at it – and they'll just be two normal kids doing normal stuff. He can almost see how excited Sam will be at getting to see the fireworks for real rather than on tv or in the distance out of a window – he was hyper enough over the shitty little fireworks Dean stole on July 4th so they could have their own display in the motel car park, which were all noise and a pretty pathetic bang at the end all things considered, hardly worth the effort except that they made Sam happy – and isn't that kinda what all this about? Why they don't go hunting, why Dad leaves them out of that side of things? That Sam gets to be a kid just a bit longer?
“Fine. Okay. Stop looking at me like that” So Dean's the one who breaks off eventually, sulky with embarrassment at himself for breaking that easily (Sam really has got him wound around his little finger, huh?). “We go there and nowhere else, though.” - and then Sam gets another pointed look, this one all Dean (in as far as any of his expressions are 'all Dean' and not a little bit of Dad mixed with whatever telly tells him is 'cool' right now), the I'm deadly serious face. “And if you tell Dad I let you go out I'll end you”
