“Yeah, right, laugh it up. Bitch” Dean's tone is still wounded, but the way he's shaking his head he's also amused (in a everything's something like normal way rather than a being shot down is awesome one, of course) and soon enough Sam's on his feet and they head out to the kitchen just in time to catch the end of the mother-daughter exchange.
Jo rattles off some orders and Dean fires off a lazy half-salute, still grinning, and leans in to Sam with a stage-whisper - “See, Sammy. Bossy chicks. Am I right?” - before pulling away into the kitchen, riffling through the freezer first, then the fridge for the bacon, and then the cupboards, he guesses. It's an odd feeling; Ellen had told him it was fine to raid the kitchen, of course, but last night he'd been too distracted to really process what that meant beyond grabbing and nuking a can of soup and now it's... yeah, it's odd. Like Sam said, they don't really 'do' kitchens and store-cupboards and even though he's been invited in it still feels like an intrusion. More so, weirdly, than the whole 'hey, I got your daughter kidnapped, can I kip on the couch?' thing...
In short, Dean's got issues, and issues with weird things like the notion of 'home' at that, but that's nothing especially revolutionary or worthy of comment, okay? Moving swiftly on.
Kevin Cronin's voice filters through into the kitchen and Dean winces as he's taking various bits-and-pieces out of one of the cupboards, setting down salt and pepper and that other things she mentioned (man, who'd've thought burgers had this much stuff in them?), shoots her you can't be serious? look as she comes back in to join them.
“REO? Jesus, someone shoot me already; I'm hoping that's just on 'cos your fingers are smashed-up pretty good and you can't really press the buttons right.”
