The Myth of the Open Road

I don't think Sam is looking down his nose, so much as he doesn't get it. I think Sam is showing what a lot of people (including fans apparently) don't understand about disabilities and aging. I doubt he's ever been exposed to either much, so that isn't too surprising, although he's supposed to be the more empathetic brother (or rather he was - until they totally screwed up his character - but that's a different rant!) I think they needed to have the contrast there, to make the point: Bobby stuck in the wheelchair and has been for a few weeks at least; Dean suddenly aged and not as challenged mobilitywise as Bobby, but still challenged in some degrees. And Sam, whole, healthy and young. At least I hope that's what they were showing, otherwise, I'm ready to take Bobby's gun and shoot Sam (or the writers!) for having him be so blithely cold and oblivious.
