Meta for Month-of-Meta: Disability and Breaking Bad

I'm not signed up with this topic or anything, but it's meta so I'm cross-posting it here hoping it might be of interest. I've been thinking about Breaking Bad and the way it handles disability. There's probably discussions of this somewhere that I just haven't seen, I've read so many things about how Glee handles its disabled characters (in the usual Glee way, which means it's a mess), but the character of Walter Jr. is never brought up. I've kept spoilers vague and to a minimum, and I'm hoping it might make sense even if you don't watch the show. ( So here are my many thoughts on this subject... )
